One example is the cellular disposal system, called autophagy, which is disrupted in patients with Alzheimer&rsquo;s disease, causing the accumulation of toxic protein plaques characteristic of the disease. Jae-sung Bae and colleagues had earlier noted that the brains of Alzheimer&rsquo;s disease patients have elevated levels of an enzyme called acid sphingomyelinase (ASM), which breaks down cell membrane lipids prevalent in the myelin sheath that coats nerve endings. But whether increased acid sphingomyelinase directly contributes to Alzheimer&rsquo;s disease (and if so, how) was unclear.</span></p> <p><span style="font-size: 10pt;"><br />The group now finds that these two defects are linked. In mice with Alzheimer&rsquo;s disease-like disease, elevated acid sphingomyelinase activity clogged up the autophagy machinery resulting in the accumulation of undigested cellular waste. Reducing levels of acid sphingomyelinase restored autophagy, lessened brain pathology, and improved learning and memory in the mice. Provided these results hold true in humans, interfering with acid sphingomyelinase activity might prove to be an effective way to slow&mdash;and possibly reverse&mdash;neurodegeneration in patients with Alzheimer&rsquo;s disease.</span></p></div> Scientists find new clues to brain’s wiring http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/scientists-find-new-clues-to-brains-wiring 2014-07-21T15:40:00Z 2014-07-21T15:40:00Z <div id="ImageMain3" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/scientists-find-new-clues-to-brains-wiring"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/Brain_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction3" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>New research provides an intriguing glimpse into the processes that establish connections between nerve cells in the brain. These connections, or synapses, allow nerve cells to transmit and process information involved in thinking and moving the body.</strong></span></p> </div><div id="Text13" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Reporting online in&nbsp;<a href="http://www.cell.com/neuron/home" target="_blank"><em>Neuron</em></a>, researchers at Washington University School of Medicine in St Louis have identified a group of proteins that programme a common type of brain nerve cell to connect with another type of nerve cell in the brain.</span></p> <p><span style="font-size: 10pt;"><br />The finding is an important step forward in efforts to learn how the developing brain is built, an area of research essential to understanding the causes of intellectual disability and autism.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We now are looking at how loss of this wiring affects brain function in mice,&rdquo; says senior author Azad Bonni, the Edison Professor of Neurobiology and head of the Department of Anatomy and Neurobiology at the School of Medicine.</span></p> <p><span style="font-size: 10pt;"><br />Bonni and his colleagues are studying synapses in the cerebellum, a region of the brain that sits in the back of the head. The cerebellum plays a central role in controlling the coordination of movement and is essential for what researchers call procedural motor learning, which makes it possible to move our muscles at an unconscious level, such as when we ride a bicycle or play the piano.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The cerebellum also regulates mental functions,&rdquo; Bonni says. &ldquo;So, impairment of the wiring of nerve cells in the cerebellum may contribute to movement disorders as well as cognitive problems including autism spectrum disorders.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />His new results show that a complex of proteins known as NuRD (nucleosome remodelling and deacetylase) plays a fairly high supervisory role in some aspects of the cerebellum&rsquo;s construction. When the researchers blocked the NuRD complex, cells in the cerebellum called granule cells failed to form connections with other nerve cells, the Purkinje neurons. These circuits are important for the cerebellum&rsquo;s control of movement coordination and learning.</span></p> <p><span style="font-size: 10pt;"><br />Bonni and his colleagues showed that NuRD exerts influence at the epigenetic level, which means it controls factors other than DNA that affect gene activity. For example, NuRD affects the configurations of molecules that store DNA and that can open and close the coils of DNA like an accordion, making genes less or more accessible. Changing the accessibility of genes changes their activity levels. For instance, cells cannot frequently make proteins from genes in a tightly packed coil of DNA.</span></p> <p><span style="font-size: 10pt;"><br />NuRD also alters tags on the proteins that store DNA, decreasing the chances that the gene will be used. Among the genes deactivated by NuRD are two that control the activity of other genes involved in the wiring of the cerebellum.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;This tells us that the NuRD complex is very influential&mdash;not only does it affect the activity of genes directly, it also controls other regulators of multiple genes,&rdquo; Bonni says.</span></p></div> New concept for treatment of multiple brain metastases http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-concept-for-treatment-of-multiple-brain-metastases 2014-07-21T13:46:00Z 2014-07-21T13:46:00Z <div id="ImageMain4" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-concept-for-treatment-of-multiple-brain-metastases"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/040/Brainlab_brain_metastases_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction4" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Brainlab has announced the release of Elements Automatic Brain Metastases Planning. The new software will simplify stereotactic radiosurgery planning for metastatic brain tumours and is the newest addition to the Elements A La Carte software portfolio.</strong></span></p> </div><div id="Text14" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Brainlab will showcase the software at the 2014 American Association of Physicists in Medicine (AAPM) Annual Meeting and Exhibition, 20-24 July in Austin, Texas.</span></p> <p><br /><span style="font-size: 10pt;"> &ldquo;When a patient develops more than one metastasis in the brain, one of the best treatment options available &ndash; radiosurgery &ndash; becomes impractical because the treatment time increases at the same rate as the number of metastases,&rdquo; says Stefan Vilsmeier, president and chief executive officer at Brainlab. &ldquo;With our new technology, we are poised as a company to shift the treatment paradigm and provide more treatment options and a consistent way to deliver them.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> Brain metastases are the most common type of brain tumours and the numbers continue to rise due to improved diagnostics and control of the primary disease. Radiosurgery is a critical option for the treatment of these secondary cancers. No other new technology has had a greater impact on the management of metastatic brain cancer than stereotactic radiosurgery. Whole brain radiotherapy (WBRT) is still considered the standard of care, however, it has shown that whole brain radiotherapy can only prevent new tumours arising for a maximum of six months. There is clear recognition that not all patients with brain metastases have equivalently poor survival outcome, and a significant group lives for a longer period of time, prompting the debate regarding whether the patients in at least the best-prognosis category should be treated solely with more aggressive therapies upfront and keep whole brain radiotherapy as an option for later. Brainlab Automatic Brain Metastases Planning software brings to market technology that consistently and rapidly generates radiosurgery plans for the efficient treatment of multiple metastases.</span></p> <p><br /><span style="font-size: 10pt;"> &ldquo;The Brainlab Automated Brain Metastases Planning software enables a &lsquo;monitor-unit&rsquo;, and time-efficient treatment planning and delivery, while reducing the dose to healthy brain tissue,&rdquo; says Niko Papanikolaou, chief medical physicist, University of Texas Health Science Center, San Antonio, Texas, USA. &ldquo;This novel approach to the treatment of metastatic brain tumours from Brainlab can potentially benefit several patients that are currently receiving whole brain radiation. We can now plan and treat metastatic brain cancer, for patients with larger volumes and higher number of metastases without the anticipated association of a decline in neurocognitive function.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;"> Brainlab Automatic Brain Metastases Planning automatically selects a group of metastases in such a way that the &lsquo;multi-leaf collimator&rsquo;, or treatment beam shaper, fits to the shapes of these selected targets without leaving gaps. The algorithm generates an optimised &lsquo;volumetric conformal&rsquo; radiosurgery plan in a matter of minutes after all metastases have been outlined and the clinical user can focus on reviewing and approving the plan in various innovative and comprehensive views. With this new treatment concept, the software creates an optimised dose distribution no matter if one or ten metastases are being treated.</span></p></div> Making a mental match: Pairing a mechanical device with stroke patients http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/making-a-mental-match-pairing-a-mechanical-device-with-stroke-patients 2014-07-18T12:24:00Z 2014-07-18T12:24:00Z <div id="ImageMain5" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/making-a-mental-match-pairing-a-mechanical-device-with-stroke-patients"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/040/Georgia-Tech-stroke-device_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction5" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>The repetitive facilitation exercise is one of the most common rehabilitation tactics for stroke patients attempting to regain wrist movement. Stroke hemiparesis individuals are not able to move that part of their body because they cannot create a strong enough neural signal that travels from the brain to the wrist.</strong></span></p> </div><div id="Text15" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">With repetitive facilitation exercise, however, patients get a mental boost. They are asked to think about moving. At the same time, a practitioner flexes the wrist. The goal is to send a long latency response from the stretch that arrives in the brain at the exact time the thought happens, creating a neural signal. The result is a strong, combined response that zips back to the forearm muscles and moves the wrist.</span></p> <p><span style="font-size: 10pt;">It all happens in a span of approximately 40 to 60 milliseconds.&nbsp;</span><br /> <br /><span style="font-size: 10pt;"> &ldquo;Timing is everything. When the window is that small, it is not easy for two people to match each other,&rdquo; says Georgia Institute of Technology master&rsquo;s graduate Lauren Lacey.</span></p> <p><br /><span style="font-size: 10pt;">That&rsquo;s why Lacey and a team of fellow Georgia Tech researchers created&nbsp;a mechanical device that takes people out of the process, replacing them with accurate computers. Their functional MRI-compatible hemiparesis rehab device creates a long latency stretch reflex at the exact time as a brain signal.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;It&rsquo;s kind of like trying to fill a bucket with water,&rdquo; explains Minoru Shinohara, an associate professor in Georgia Tech&rsquo;s Human Neuromuscular Physiology Lab. &ldquo;Stroke individuals can only mentally fill it halfway. The machine pours in the rest to make it full.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">So far, the research team has worked only with healthy individuals in their study. Study participants lie on a bed with the arm extended beneath a pneumatic actuator tendon hammer. In order to simulate the weak signal created by hemiparesis individuals to move their wrist, a transcranial magnetic stimulator (TMS) is placed on the heads of these healthy individuals at a 45-degree angle. Milliseconds after the hammer taps the wrist&rsquo;s tendon, the TMS creates a weak signal in the motor cortex. The responses overlap, produce and send a strong signal back to the arm, and the wrist moves.</span></p> <p><br /><span style="font-size: 10pt;">The team has successfully varied the timing of the transcranial magnetic stimulator signal and speed of the hammer to strike faster or slower depending on how much of a boost is needed to complement the brain signal. Now that the researchers have proven the viability of the transcranial magnetic stimulator-actuator system, they will next work with stroke individuals.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;The device is designed to adapt to people whether they are hyper, normo or hyporeflexive,&rdquo; says Lacey, who graduated in spring with a master&rsquo;s degree from the George Woodruff School of Mechanical Engineering.</span></p> <p><br /><span style="font-size: 10pt;">Also, because the machine is MRI-compatible, it will allow the team to study what is happening in the brain during rehab, opening the door for robotics.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Once we fully understand what is happening mentally and physiologically, we should be able to create a robot that can reproduce successful rehabilitative exercises such as repetitive facilitation exercise,&rdquo; says Jun Ueda, an associate professor in the School of Mechanical Engineering. &ldquo;It appears that the timing is the critical piece of this exercise. Robots are great at timing, so the results are very promising for robotics.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">The Georgia Tech team was assisted by researchers at Japan&rsquo;s Kagoshima University, Kazumi Kawahira, Megumi Shimodozono and Yong Yu, who originally performed clinical studies of conventional repetitive facilitation exercise. The device was presented at the&nbsp;Design of Medical Devices Conference&nbsp;in Minneapolis, Minnesota, USA this spring.</span></p> <p><br /><span style="font-size: 10pt;">This research was partially supported by the National Science Foundation (NSF) under sub-award EEC 0540834.

However, the decline in stroke risk was concentrated mainly in the over-65 set, with little progress in reducing the risk of strokes among young people. In contrast, the drop in stroke-related deaths each decade was primarily found among those under age 65, with mortality rates holding firm in older people.</span><br /> <br /><span style="font-size: 10pt;"> A report on the results is published in the July 16 issue of the&nbsp;<a href="http://jama.jamanetwork.com/journal.aspx" target="_blank"><em>Journal of the American Medical Association</em>&nbsp;(<em>JAMA</em>)</a>.</span><br /> <br /><span style="font-size: 10pt;"> &ldquo;We can congratulate ourselves that we are doing well, but stroke is still the number four cause of death in the United States,&rdquo; says study co-author Josef Coresh, a professor of epidemiology at the Johns Hopkins Bloomberg School of Public Health. &ldquo;This research points out the areas that need improvement. It also reminds us that there are many forces threatening to push stroke rates back up and if we do not address them head-on, our gains may be lost.&rdquo;</span><br /> <br /><span style="font-size: 10pt;"> Coresh says he worries what the future of stroke will look like as the obesity epidemic, which began in the 90s, matures. As millions more are diagnosed with hypertension and diabetes &ndash; which often go hand-in-hand with obesity -- they will face increased risk for stroke.</span><br /> <br /><span style="font-size: 10pt;"> For their analysis, researchers used results from the Atherosclerosis Risk in Communities (ARIC) study, a prospective study of 15,792 residents of four US communities who were between the ages of 45 and 64 when the study began in the late 1980s. In this analysis, they followed 14,357 participants who were free of stroke in 1987, looking specifically for all stroke hospitalisations and deaths between then and the end of 2011.</span><br /> <br /><span style="font-size: 10pt;"> Seven per cent of the study sample (1,051) had a stroke over that period. Of those, 10% died within 30 days, and 21%, 40% and 58% died within one year, five years and by the end of the study in 2011. Each decade, the number of deaths occurring within 10 years of a stroke was reduced by roughly eight deaths per 100 cases. The decrease was not across the board. Instead it was primarily the result of stroke victims under the age of 65 surviving longer. While they varied by age, the results were similar across race and gender, a finding that researchers were heartened to discover since a previous study suggested African-American stroke rates were not improving.</span><br /> <br /><span style="font-size: 10pt;"> The researchers found that the decrease in stroke incidence and mortality is partly due to more successful control of risk factors such as blood pressure, smoking cessation and the wide use of statin medications for controlling cholesterol. However, an increase in diabetes likely acted in the opposite direction, pushing up stroke rates, though to a lesser extent. Stroke severity and improvements in treatment likely also impacted the data, though the study could not measure the exact role they played.</span><br /> <br /><span style="font-size: 10pt;"> The age disparities in outcomes suggest areas where physicians and researchers may want to focus in the future to prevent strokes in those under 65 and reduce deaths in those over 65.</span><br /> <br /><span style="font-size: 10pt;"> Nearly 800,000 Americans suffer strokes each year; of those, about 600,000 are first-time strokes. &ldquo;Stroke is not only one of the main causes of death, but a leading cause of long-term disability in adults. Therefore, prevention is the best strategy,&rdquo; says study leader Silvia Koton, a visiting faculty member at the Bloomberg School and incoming nursing department chair at Tel Aviv University.</span><br /> <br /><span style="font-size: 10pt;"> National data show that the number of death certificates listing stroke as the underlying cause of death has decreased for a long time. However, only research studies such as this one can distinguish whether the decline is due to a reduction in the number of strokes or whether people are just living longer after having them, researchers say. In this study, researchers also confirmed the occurrence of each stroke by reviewing each medical chart using uniform criteria. Researchers focused on deaths from all causes because following a stroke, many patients die from other causes including heart disease and pneumonia.</span><br /> <br /><span style="font-size: 10pt;"> &ldquo;Since rates are not equally falling across the board, physicians and policymakers need to pay closer attention to specific subgroups,&rdquo; Koton says. &ldquo;These data are also helpful in monitoring the results of how we care for people of all ages, hopefully helping them even before they have a stroke.&rdquo;</span><br /> <br /><span style="font-size: 10pt;"> The ARIC study is supported by contracts with the National Institutes of Health&rsquo;s National Heart, Lung, and Blood Institute as well as NHLBI grants.</span><br /> <br /><span style="font-size: 10pt;"> &ldquo;Stroke Incidence and Mortality Trends in US Communities, 1987 to 2011,&rdquo; was written by Silvia Koton; Andrea L.C.

The trial was the first of its kind to study the treatment of carotid artery stenosis by placing a stent via direct access to the common carotid artery in the neck in an entirely new minimally invasive procedure. The device under study is the company&rsquo;s Enroute transcarotid neuroprotection system which incorporates proven surgical principles to protect the brain from a stroke during carotid angioplasty and stenting, and features a mechanism to divert dangerous debris away from the brain by temporarily reversing blood flow. Data from the trial will be used to support 510(k) clearance of the Enroute transcarotid neuroprotection system as well as pre-market approval of the Enroute transcarotid stent system.</strong></span></p> </div><div id="Text17" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;The Enroute transcarotid neuroprotection system was designed to reduce the excess stroke risk of a carotid stent procedure, while at the same time minimising the surgical risks of an open carotid artery surgery known as carotid endarterectomy,&rdquo; says Sumaira Macdonald an expert in the field of carotid artery disease and Silk Road Medical&rsquo;s chief medical officer. &ldquo;Until now, carotid stents were typically placed via the femoral artery approach, which is about three feet from the culprit carotid stenosis, and requires navigation of catheters and other instruments through often hostile territory, increasing the risk of stroke during or immediately after the procedure,&rdquo; she says. &ldquo;We know that carotid stents are effective in preventing strokes in the long term, but we need a safer way to deliver them. The Silk Road procedure moves the access point to within inches of the stenosis to avoid at-risk steps and provides a surgically-inspired method of protecting the brain throughout the simplified procedure.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">By contrast, the gold standard carotid endarterectomy procedure requires a large incision in the neck and a surgery that carries some risk of nerve damage, bleeding, scarring and infection. The Silk Road procedure is designed to reduce these surgical risks as well. &ldquo;Historically, there has not been a safe and effective minimally invasive procedure that could hold up to the clinical outcomes established by carotid endarterectomy. This new procedure may be it,&rdquo; says Richard Cambria, chief, Division of Vascular and Endovascular Surgery at Massachusetts General Hospital and The Robert R Linton MD Professor of Vascular and Endovascular Surgery at the Harvard Medical School. &ldquo;The results from our centre will be announced at the VEITH Symposium.&rdquo; Cambria serves as the National co-principal investigator for the ROADSTER trial.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;The ROADSTER trial included an elite, multi-disciplinary group of physicians across the US and Europe with vast experience in treating carotid disease,&rdquo; says Christopher Kwolek, director of the Vascular and Endovascular training programme at Massachusetts General Hospital, chief of Vascular Surgery at Newton Wellesley Hospital, and National co-principal investigator for the ROADSTER trial. &ldquo;Similar to important endovascular innovations in aortic aneurysms and peripheral arterial disease, this new minimally invasive procedure will be an important step forward in the treatment of carotid artery disease for the vascular specialist.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Erica Rogers, chief executive officer for Silk Road Medical, comments, &ldquo;We believe the ROADSTER data will support clearance and approval of our planned marketing applications with the FDA.

According to the authors, this study is the first to examine the role of discharge disposition in an acute stroke treatment trial in the modern era.</strong></span></p> </div><div id="Text18" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Rishi Gupta (Wellstar Neurosurgery, Marietta, USA) and others evaluated the demographic data from the SENTIS (The safety and efficacy of NeuroFlo technology in ischemic stroke) trial to determine the impact of stroke severity and discharge disposition on 90-day outcomes in US patients&mdash;the results were published in the <a href="http://jnis.bmj.com/" target="_blank"><em>Journal of NeuroInterventional Surgery</em></a>.</span></p> <p><br /><span style="font-size: 10pt;">The <a href="http://clinicaltrials.gov/ct2/show/NCT00119717?term=SENTIS&amp;rank=1" target="_blank"><strong>SENTIS</strong></a> trial, originally published in the <a href="http://www.ajnr.org/" target="_blank"><em>American Journal of Neuroradiology</em></a> in 2013, was a multicentre, prospective, randomised controlled trial that evaluated the safety and effectiveness of the NeuroFlo catheter (CoAxia) in stroke patients compared to standard medical therapy. In the trial, it was found that there were consistent reductions in all-cause and stroke-related mortality in the NeuroFlo-treated patients. Although the results showed that treatment with NeuroFlo was safe, it was also demonstrated that there was not a benefit of doing so when compared to standard medical therapy. Therefore, Gupta and colleagues analysed NIHSS from days one and four, discharge disposition and 90-day modified Rankin Score to investigate whether discharge disposition to home or acute rehabilitation is associated with a clinical favourable outcome from the SENTIS data.</span></p> <p><br /><span style="font-size: 10pt;">Of the 292 patients, 153 (52.1%) were discharged to an inpatient rehabilitation facility, 11 (38%) to home and 28 (9.6%) to a skilled nursing facility.</span></p> <p><br /><span style="font-size: 10pt;">Two out of the 28 patients discharged to a skilled nursing facility achieved a 90-day modified Rankin Score of &le;2 compared with the 60/153 patients in the inpatients rehabilitation facility (OR 8.39, 95% CI 1.92 to 36.64, p=0.0047).&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />According to Gupta <em>et al,</em> these results show that an association between outcomes and discharge disposition remains after adjustments for age and admission NIHSS.</span></p> <p><br /><span style="font-size: 10pt;">They add that three of the 50 patients with NIHSS of &ge;14 at four days achieved modified Rankin Scored of 0&ndash;2 at 90 days.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;This analysis shows that discharge to an inpatient rehabilitation facility is associated with better neurological outcomes than discharge to a skilled nursing facility. Additionally, patients with NHISS of &ge;14 at day four are unlikely to achieve independent function.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Co-author Samir R Belagaje, assistant professor, Neurology and Rehabilitation Medicine, Emory University School of Medicine, USA, spoke to <em>NeuroNews</em> and shed light on the implications of the findings of the study for the future.</span></p> <p><span style="font-size: 10pt;"><strong><br />How could these findings be applied to patient care after stroke in the future?</strong></span></p> <p><br /><span style="font-size: 10pt;">Our results reinforce the concept that care of patients with stroke must be optimised in all phases of their care and not just the acute phase. In the real world, neurologists and other healthcare practitioners should try to get their patients to their acute rehabilitation (inpatient rehabilitation) whenever possible and when their patients are unable to go home immediately. In the research world, our research helps with the design of future clinical trials of acute stroke intervention by pointing out the importance of the discharge disposition and possibly standardised. Our data may also point to further examination of the decision process in determining which patients go to inpatient rehabilitation facility vs. skilled nursing facility and help get more patients to an inpatient rehabilitation facility to improve their overall outcome.</span></p> <p><span style="font-size: 10pt;"><strong><br />Would discharging all patients to an inpatient rehabilitation facility be cost-effective?</strong></span></p> <p><br /><span style="font-size: 10pt;">We do not have any data at this point to clearly say one way or another. It is probably not cost-effective as there are some patients who, because of their stroke severity, simply do not make the improvements to justify the resources in terms of therapists and the intensity of therapy. They would do the same with less intensity as provided in a skilled nursing facility.&nbsp;</span></p> <p><br /><span style="font-size: 10pt;">Furthermore, there are some patients because of their age, stroke severity, or other medical comorbidities are unable to tolerate the intensity of the inpatient facility rehabilitation and could actually do worse. This would result in more acute hospitalisations, longer stays in facilities, and worsened outcomes all of which would add further costs making this strategy less cost-effective.</span></p></div> Banner Alzheimer&apos;s Institute partners with Novartis in new study of Alzheimer&apos;s prevention treatments http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/banner-alzheimers-institute-partners-with-novartis-in-new-study-of-alzheimers-prevention-treatments 2014-07-16T15:19:00Z 2014-07-16T15:19:00Z <div id="Introduction9" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Researchers from the Banner Alzheimer&rsquo;s Institute (BAI) have announced a partnership with Novartis in a pioneering medical trial to determine whether two investigational anti-amyloid drugs&mdash;an active immunotherapy and an oral medication&mdash;can prevent or delay the emergence of symptoms of Alzheimer&rsquo;s in people at particularly high risk for developing the disease at older ages.</strong></span></p> </div><div id="Text19" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The five-year APOE4 trial will involve more than 1,300 cognitively healthy older adults, ages 60&nbsp;to 75<em>,&nbsp;</em>at high risk of developing symptoms of&nbsp;Alzheimer&rsquo;s because they inherited two copies of the apolipoprotein E (APOE4) gene&mdash;one from each parent. About 2% of the world&rsquo;s population carries two copies of this gene and one in four people carry one copy of the APOE4 gene, which is strongly linked to late-onset Alzheimer&rsquo;s.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;We are taking clinical trials to a critical new stage,&rdquo; says Pierre N Tariot, study director for BAI, an arm of Banner Health, one of the largest non-profit healthcare systems in&nbsp;the United States. &ldquo;This approach shifts the research paradigm from trying to reverse disease damage to attacking and preventing its cause, years before symptoms could surface.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">The trial&mdash;subject to regulatory authority approval&mdash;will begin in 2015 at approximately 60 sites in&nbsp;Europe&nbsp;and North America, including BAI&rsquo;s headquarters in&nbsp;Phoenix, Arizona, USA.</span></p> <p><br /><span style="font-size: 10pt;">The active immunotherapy is aimed at triggering the body&rsquo;s immune system to produce antibodies that attack different forms of the amyloid protein, which many researchers have suggested plays a critical role in the development of Alzheimer&rsquo;s. The oral medication is a BACE (beta-secretase1) inhibitor, designed to prevent the production of different forms of the amyloid protein.</span></p> <p><br /><span style="font-size: 10pt;">The two drugs, which will be tested separately, are intended to stop the accumulation of amyloid. The drugs are being introduced even before amyloid accumulates in some of the participants&rsquo; brains. The trial will increase the chance of finding treatments that will prevent, slow or delay the loss of memory and other cognitive abilities associated with Alzheimer&rsquo;s.</span></p> <p><br /><span style="font-size: 10pt;">Study participants will be recruited via multiple venues, including the Alzheimer&rsquo;s Prevention Registry website created by BAI in 2012. The registry currently has more than 37,000 potential volunteers and is aiming to recruit more than 250,000.</span></p> <p><br /><span style="font-size: 10pt;">Volunteers who meet the study criteria will be asked to mail a sample of their genetic material (such as a cheek swab) to a laboratory. The volunteers will learn the results of that test in the context of possibly enrolling in the trial.</span></p> <p><br /><span style="font-size: 10pt;">Volunteers who are selected for the API APOE4 study will receive genetic counselling. &ldquo;We are keenly aware of the extreme sensitivity and emotional impact of disclosing genetic information,&rdquo; Langbaum says.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;There are no guarantees that any of these investigational treatments will prevent the clinical onset of Alzheimer&rsquo;s disease,&rdquo; says Eric M Reiman, one of the study directors for BAI. &ldquo;But we are grateful for these opportunities to find out.&rdquo;</span></p></div> Worldwide Alzheimer&apos;s and dementia epidemic grows http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/worldwide-alzheimers-and-dementia-epidemic-grows 2014-07-15T15:41:00Z 2014-07-15T15:41:00Z <div id="ImageMain10" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/worldwide-alzheimers-and-dementia-epidemic-grows"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/040/World_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction10" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>While the global epidemic of Alzheimer&rsquo;s disease continues to grow, new data on lower incidence in the &ldquo;youngest old&rdquo; from developed countries in Europe&nbsp;and&nbsp;the United States&nbsp;suggest the possibility of reducing risk and/or preventing the disease, according to the results of several research studies announced at the Alzheimer&rsquo;s Association International Conference2014 (AAIC&nbsp;2014) in&nbsp;Copenhagen, Denmark. Scientists suggest higher education levels and more aggressive treatment of cardiovascular disease may be key.</strong></span></p> </div><div id="Text110" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Pointing in the other direction, researchers reported at AAIC 2014 that incidence and prevalence of Alzheimer&rsquo;s in developing countries such as&nbsp;Colombia, and large regions of&nbsp;Asia&nbsp;and&nbsp;Africa, may be severely underreported. They also raise questions about the effects of the growing incidence of obesity and diabetes in developed countries, both of which are associated with increased risk of cognitive decline and dementia.</span></p> <p><span style="font-size: 10pt;">For clarity following are the definitions of prevalence and incidence:</span></p> <ul> <li><span style="font-size: 10pt;">Prevalence &ndash; the number or proportion of cases of a disease in a population. (ie., How many people have Alzheimer&rsquo;s disease in the USA right now?)</span></li> <li><span style="font-size: 10pt;">Incidence &ndash; the number of new cases of a disease in a population over a given time. (ie., How many new cases of Alzheimer&rsquo;s are there this year in&nbsp;Denmark?)</span></li> </ul> <p><span style="font-size: 10pt;">&ldquo;The good news is that recent trends in developed countries in&nbsp;Europe&nbsp;and the USA suggest that reduction and possibly even prevention of Alzheimer&rsquo;s disease might be possible &ndash; but, at the same time, we must acknowledge the growing worldwide epidemic,&rdquo; says&nbsp;Maria Carrillo, Alzheimer&rsquo;s Association vice president of Medical and Scientific Relations. &ldquo;We must continue efforts to halt this terrible scourge that devastates families and economies.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;According to new data reported at AAIC 2014, Alzheimer&rsquo;s and dementia incidence and prevalence in developing countries may be much higher than previously thought, and rising rates of obesity and diabetes pose an unknown but potentially serious threat to cognitive health throughout the world. Many questions remain, and the only way we can get the answers is through more research,&rdquo; Carrillo says.</span></p> <p><br /><span style="font-size: 10pt;">There are hints in the literature that engaging in more challenging mental activities, such as higher levels of education or intellectually demanding occupations, may increase cognitive reserve and thereby reduce the risk of developing Alzheimer&rsquo;s or another dementia.</span></p> <p><span style="font-size: 10pt;"><strong><br />Review of recent data suggests fewer new cases of Alzheimer&rsquo;s in&nbsp;the United States&nbsp;and&nbsp;Europe<br /> <br /> </strong>Worldwide prevalence of Alzheimer&rsquo;s disease is projected to increase in the decades ahead as the planet&rsquo;s population ages, but recently published studies from&nbsp;the United States,&nbsp;the Netherlands,&nbsp;Sweden, and&nbsp;England suggest a decline in incidence or prevalence of dementia (or both) in those countries, according to a review of recent research conducted by&nbsp;Kenneth Langa of the&nbsp;University of Michigan&nbsp;and the VA Ann Arbor Center for Clinical Management Research, and reported at a plenary session at AAIC 2014.</span></p> <p><span style="font-size: 10pt;"><br />Langa observed from the studies that a number of factors, especially rising levels of education and more aggressive treatment of cardiovascular risk factors such as hypertension and high cholesterol, may be leading to improved brain health and consequent decline of numbers of new cases of Alzheimer&rsquo;s disease and dementia in certain countries or regions of the world.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Whether this trend will continue in the face of rising levels of obesity and diabetes, and whether it is also true in low- and middle-income countries, are key unanswered questions,&rdquo; says Langa. &ldquo;The answers will have enormous implications for the extent of the future worldwide impact of Alzheimer&rsquo;s disease and dementia in the decades ahead.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />Extent of dementia in&nbsp;Asia&nbsp;and Sub-Saharan Africa may be severely underestimated<br /> <br /> </strong>In 2009, Alzheimer&rsquo;s Disease International (ADI) published data on global prevalence of dementia based on a review of 154 worldwide studies and United Nations (UN) population projections. Alzheimer&rsquo;s Disease International carried out an update on that data for the&nbsp;December 2013&nbsp;G8 Dementia Summit in&nbsp;London, focusing primarily on new evidence from&nbsp;Asia and Sub-Saharan Africa, and presented the results at AAIC 2014.</span></p> <p><span style="font-size: 10pt;"><br />Based on a meta-analysis of Chinese and Sub-Saharan African studies combined with the latest UN population projections, Alzheimer&rsquo;s Disease International concluded that the 2009 estimates of worldwide Alzheimer&rsquo;s disease were too low. Alzheimer&rsquo;s Disease International now estimates that 44.35 million people in the world were living with dementia in 2013, significantly up from the earlier estimate of 36 million people living with dementia in 2010. They project that the number will rise to 75.62 million in 2030 &mdash; 15% higher than the 2009 estimate &mdash; and 135.46 million in 2050, which is 17% higher than the 2009 Alzheimer&rsquo;s Disease International estimate.</span></p> <p><br /><span style="font-size: 10pt;">Specifically in the two focus regions, the researchers found that dementia prevalence increased for&nbsp;East Asia from about 5% to about 7%, and in Sub-Saharan African regions from a range of roughly 2 to 4% to 4.76%.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Dementia, including Alzheimer&rsquo;s disease, is one of the biggest global health challenges facing our generation,&rdquo; says&nbsp;Marc Wortmann, executive director, Alzheimer&rsquo;s Disease International. &ldquo;As more and better data becomes available, the effect we&rsquo;ve seen is a reduction in the variation of prevalence between world regions.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;In addition, newly available data suggests that the current burden and future impact of the global dementia epidemic has been underestimated, particularly for the&nbsp;Asia&nbsp;and Sub-Saharan Africa. Especially in light of these revised estimates, there is an urgent need to develop policies to face this disease in all countries of the world, and to enhance our efforts in finding a cure or treatment that can delay the onset of dementia,&rdquo; Wortmann adds.</span></p> <p><span style="font-size: 10pt;"><strong><br />New sases of dementia decline over three decades in the Framingham Heart Study<br /> <br /> </strong>At AAIC 2014,&nbsp;Claudia L Satizabal of&nbsp;Boston University School of Medicine&nbsp;and colleagues reported on the results of a study of dementia trends among participants in the Framingham Heart Study, an ongoing, long-term (since 1948), multi-generational cardiovascular health study of residents of&nbsp;Framingham, Massachusetts, USA, to which dementia tracking has been added since 1975.</span></p> <p><span style="font-size: 10pt;"><br />Framingham Study participants undergo comprehensive assessments for cardiovascular risk factors every two to four years, and remain under intensive surveillance for dementia and stroke. Study researchers defined four non-overlapping five-year time windows (epochs) across the past three decades, each beginning with a baseline examination, and studied new cases of dementia among all dementia-free participants age 60 and older.</span></p> <p><br /><span style="font-size: 10pt;">After adjusting for age at entry and gender, the researchers found that compared with the first epoch, the second epoch had a 22% reduction in new cases of dementia, the third had a 38% reduction, and the fourth had a 44% reduction. The reduction was strongest in participants between age 60 and 69.</span></p> <p><br /><span style="font-size: 10pt;">The researchers found the decrease in dementia incidence was greatest in women across all epochs, while men showed a more gradual decrease over time. The decreasing trend in dementia incidence was true for individuals with a higher educational level, defined as having a high school diploma, whereas individuals without a high school diploma did not appear to benefit from this reduction.</span></p> <p><br /><span style="font-size: 10pt;">During that 30-year time period, the researchers observed among the participants a substantial improvement in educational achievement, better management of blood pressure, higher levels of HDL cholesterol, and a considerable decline in smoking, heart disease and stroke across the same epochs. However, an increasing trend in obesity and diabetes was seen in this population.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;These reductions in age-specific rates of new cases of dementia in the Framingham Study participants might be partly explained by the beneficial trends we observed in educational attainment and heart health risk factors,&rdquo; says Satizabal. &ldquo;This leads us to cautious optimism that some cases of dementia may be preventable. However, one of the limitations of this work is that the&nbsp;Framingham&nbsp;sample is largely of European descent. Additional studies are needed in populations of different racial and ethnic backgrounds.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />In&nbsp;Colombia, dementia and Alzheimer&rsquo;s disease might be underestimated by up to 50%<br /> <br /> </strong>To date,&nbsp;Colombia&nbsp;has had only one study, known as EPINEURO, which attempted to estimate the country&rsquo;s dementia prevalence from representative samples of the population 20 years ago. Using updated population estimates and prevalence estimates published in the international literature,&nbsp;Yuri Takeuchi of Universidad Icesi (Colombia) and colleagues estimated the number of people with dementia, and especially Alzheimer&rsquo;s disease, in&nbsp;Colombia&nbsp;by stage of the disease. The results were reported at AAIC 2014.</span></p> <p><br /><span style="font-size: 10pt;">The researchers created three models for Alzheimer&rsquo;s prevalence in the country, each using different projections for the proportion of people with mild, moderate, and severe disease, and different theoretical assumptions on the transitions between stages. They found that the number of people with Alzheimer&rsquo;s in Colombia&nbsp;could be as much as 220,000 in 2015, and 260,000 in 2020. The scientists calculate that current estimates for Alzheimer&rsquo;s disease and other dementias in&nbsp;Colombia&nbsp;might be too low by as much as 50%. (The prevalence estimate of dementia for&nbsp;Colombia&nbsp;in people over 65 used in the study was 6%, according to Takeuchi.)</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;To our knowledge, this is the first attempt to model and estimate dementia prevalence by stage of disease in the developing world; it is certainly the first attempt in&nbsp;Colombia,&rdquo; says Takeuchi. &ldquo;The fastest growth in ageing is happening in developing countries such as&nbsp;Colombia. This has profound implications not only for older people themselves, but for their households, social and community infrastructure, and social policy. These estimations by stage of disease are key information for policymakers because both the social burden and social costs are substantially different depending on the stage of disease.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />Dementia in&nbsp;Germany&nbsp;declined between 2007 and 2009<br /> <br /> </strong>Gabriele Doblhammer of the German Center for Neurodegenerative Diseases (DZNE) and colleagues conducted a study exploring short-term dementia trends in&nbsp;Germany, and reported the results at AAIC 2014.</span></p> <p><br /><span style="font-size: 10pt;">The research is based on claims data from the largest public health insurance company in&nbsp;Germany&nbsp;which covers about one-third of the total population aged 50+ and more than half of the oldest-old. The data include complete records of the inpatient and outpatient services, including dementia diagnosis. The complete insured population of roughly five million people at risk of dementia and about 600,000 dementia cases was used to study the prevalence; a 2.5% sample was the basis for the incidence study.</span></p> <p><br /><span style="font-size: 10pt;">The researchers found that between 2007 and 2009, the total number of people with dementia decreased significantly among German women age 74 to 85. Dementia prevalence in 2009 was 3.6% lower than in 2007 and 1.8% lower than in 2008. Over that period, new cases of dementia decreased significantly for both men and women.</span></p> <p><br /><span style="font-size: 10pt;">According to the researchers, over the last decade there was reduction in new cases of cerebrovascular disease in&nbsp;Germany&nbsp;and a &ldquo;better treatment of vascular risk factors such as high blood pressure, hypercholesterolemia, and diabetes mellitus.&rdquo; Among the elderly, increasing levels of education and wealth also were observed.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;This was the first study to explore dementia trends in&nbsp;Germany,&rdquo; says Doblhammer. &ldquo;The ageing of the babyboomers and the increasing life expectancy will lead to more dementia cases in old age. It is necessary to explore the modifiable risk factors of dementia in order to prevent the occurrence of the disease. In addition, more research is needed whether the increasing obesity epidemic and related diseases, such as the metabolic syndrome, may counterbalance the positive trends we are observing today,&rdquo; the researchers add.</span></p></div> C2N expands partnership with Washington University School of Medicine http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/c2n-expands-partnership-with-washington-university-school-of-medicine 2014-07-15T15:11:00Z 2014-07-15T15:11:00Z <div id="ImageMain11" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/c2n-expands-partnership-with-washington-university-school-of-medicine"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/blood_tests_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction11" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>C<sub>2</sub>N Diagnostics has announced that it has expanded its partnership with Washington University School of Medicine (WUSM) in St Louis, USA. The objective of this collaboration is to commercialise a clinical blood test for detecting the earliest stages of Alzheimer&rsquo;s disease as well as mild cognitive impairment. Under terms of the agreement, C<sub>2</sub>N has acquired the exclusive worldwide commercial license rights to a suite of technologies developed in the laboratories of professors Randall Bateman and David Holtzman in the Department of Neurology at WUSM.</strong></span></p> </div><div id="Text111" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The licensed technologies build upon the Stable Isotope Labelling Kinetics (SILK) platform pioneered at WUSM and already marketed by C<sub>2</sub>N. The new technologies enable a novel approach to measure the metabolism of brain-derived proteins implicated in Alzheimer&rsquo;s disease and mild cognitive impairment. For the first time, instead of analysing Alzheimer&rsquo;s disease proteins in cerebrospinal fluid, it is now possible to detect the same metabolic markers in patients&rsquo; blood samples.</span></p> <p><br /><span style="font-size: 10pt;">This capability has implications for the advancement of new treatments, early prevention, and personal wellness. Alzheimer&rsquo;s is now one of the major global healthcare concerns. Approximately 44 million people currently have clinical Alzheimer&rsquo;s disease. Millions more have mild cognitive impairment that places them at high risk for progression to clinical Alzheimer&rsquo;s disease. The number of cases of Alzheimer&rsquo;s disease and mild cognitive impairment are expected to increase sharply in the years ahead due to the aging baby boomer population.</span></p> <p><br /><span style="font-size: 10pt;">Pharmaceutical companies developing new drugs targeting Alzheimer&rsquo;s disease increasingly recognise that early intervention provides the greatest chance of halting or reversing disease progression. Biomarkers are needed to detect this early pathology, which can begin at least 15 years before the onset of any clinical symptoms. At the same time, dynamic biomarkers, like those offered by the SILK platform, may also track treatment responses during the pre-symptomatic stages of disease.</span></p> <p><br /><span style="font-size: 10pt;">Since 2008, C<sub>2</sub>N has applied the SILK-A&beta;&nbsp;test to measure the kinetics of beta-amyloid in cerebrospinal fluid. The test has served as a primary endpoint in clinical drug studies to demonstrate target engagement and guide dose selection. The SILK-A&beta;&nbsp;isoforms test is also highly sensitive to identifying people with brain amyloidosis (one of the earliest indicators of Alzheimer&rsquo;s disease), even before amyloid deposits are seen with brain imaging. Still, the more invasive nature of cerebrospinal fluid sampling has impeded the full potential of the SILK-A&beta;&nbsp;method.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;With a simplified SILK-A&beta;&nbsp;test available through blood sampling, we now have an opportunity to validate a unique therapeutic and diagnostic marker,&rdquo; states Joel B Braunstein, chief executive officer of C<sub>2</sub>N. &ldquo;We plan to achieve this validation by collaborating with pharmaceutical companies that are testing their compounds in phase 2 and phase 3 clinical studies, as well as by participating in natural history studies tracking the progression of Alzheimer&rsquo;s disease. If successful, we expect to be able to offer a reliable and informative screening test that is also convenient for patients.&rdquo;</span></p></div> St Jude Medical announces definitive agreement to acquire NeuroTherm http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/st-jude-medical-announces-definitive-agreement-to-acquire-neurotherm 2014-07-14T16:48:00Z 2014-07-14T16:48:00Z <div id="Introduction12" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>St Jude Medical has announced that it has signed a definitive agreement to acquire privately held&nbsp;NeuroTherm, a manufacturer of interventional pain management therapies, for approximately&nbsp;US$200 million&nbsp;in cash.</strong></span></p> </div><div id="Text112" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">NeuroTherm is a global leader in the treatment of spinal pain using radiofrequency ablation (RFA), a segment of the chronic pain market in which&nbsp;St Jude Medical does not currently participate.

Additionally, in a population of people age 90 and older, high blood pressure was seen to help protect against cognitive decline. This is counter intuitive as heart health risk factors, including hypertension, are generally considered to elevate risk of Alzheimer&rsquo;s and other dementias.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Determining more specifically the factors that raise and lower risk of Alzheimer&rsquo;s disease and other dementias is an essential component in our battle against the Alzheimer&rsquo;s epidemic,&rdquo; says&nbsp;Heather Snyder, Alzheimer&rsquo;s Association director of Medical and Scientific Operations. &ldquo;We are now getting a more clear idea of the opportunities for risk reduction through behaviour changes and other health factors. We are learning that Alzheimer&rsquo;s risk and protective factors may change over the course of our lives.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;These studies from AAIC 2014 underscore the need to fund larger, longer-term studies in different and diverse populations to enable us to develop helpful &rsquo;prescriptions&rsquo; for lifestyle change &ndash; for example, which foods to eat and avoid, how much physical activity and what types &ndash; and to learn more specifically about how Alzheimer&rsquo;s and dementia risk factors change as we age,&rdquo; Snyder adds.</span><br /><br /></p> <p><span style="font-size: 10pt;"><strong>Cognitively stimulating activities are associated with greater brain volumes and higher cognitive test scores</strong></span></p> <p><br /><span style="font-size: 10pt;">Prior studies have suggested that participation in activities that stimulate thought, new ideas, new memories, and that challenge us mentally may encourage brain health as we age and possibly reduce risk of cognitive impairment and dementia. The mechanisms underlying this possible effect are not currently well understood.</span></p> <p><br /><span style="font-size: 10pt;">At AAIC 2014,&nbsp;Stephanie Schultz, and colleagues at the Wisconsin Alzheimer&rsquo;s Institute and the Wisconsin Alzheimer&rsquo;s Disease Research Center reported on the results of a study of 329 cognitively normal middle-aged adults (mean age=60.3 years, 69% women) enrolled in the Wisconsin Registry for Alzheimer&rsquo;s Prevention. Forty per cent of the participants were positive for the APOe4 gene and 74% had a parental family history of Alzheimer&rsquo;s, both of which are known to increase the risk for developing Alzheimer&rsquo;s.</span></p> <p><br /><span style="font-size: 10pt;">These at-risk adults reported their current engagement in cognitively-stimulating activities using the Cognitive Activity Scale (CAS), underwent MRI brain imaging, and completed a comprehensive battery of neurocognitive tests. The CAS consists of 10 items that ask individuals how often they participate in various cognitive activities, such as reading books and going to museums. The scientists focused on CAS-Games, which is a single item on the scale that asks participants how often they play games such as cards, checkers, crosswords or other puzzles.</span></p> <p><br /><span style="font-size: 10pt;">After controlling for factors known to influence brain volume and cognitive test scores, such as age and gender, the researchers found that a higher self-reported frequency of game playing was significantly associated with greater brain volume in several regions involved in Alzheimer&rsquo;s disease (such as the hippocampus) and with higher cognitive test scores on memory and executive function.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Our findings suggest that, for some individuals, engagement in cognitively stimulating activities, especially those involving games such as puzzles and cards, might be a useful approach for preserving brain structures and cognitive functions that are vulnerable to Alzheimer&rsquo;s disease,&rdquo; says Schultz. &ldquo;More detailed studies of specific cognitive activities, including games, would help further our understanding of how an active, healthy lifestyle may help delay the development of Alzheimer&rsquo;s.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />Moderate exercise in middle age is associated with decreased risk of dementia</strong></span></p> <p><br /><span style="font-size: 10pt;">Of the growing body of research concerning lifestyle and brain health, and also the possibility of reduced risk of Alzheimer&rsquo;s and other dementias, perhaps the strongest and most consistent evidence exists for regular physical activity.</span></p> <p><br /><span style="font-size: 10pt;">Yonas E Geda, and colleagues at the Mayo Clinic investigated the relationship between timing of exercise (mid-life/50-65 vs late-life/70 and above) and risk of new cases of dementia in 280 older adults (median age=81) with mild cognitive impairment from the Mayo Clinic Study of Aging, and reported on their findings at AAIC 2014.</span></p> <p><br /><span style="font-size: 10pt;">A person with mild cognitive impairment has a slight but noticeable and measurable decline in cognitive abilities, including memory and thinking skills. These changes are serious enough to be noticed by the individuals experiencing them or to other people, but they are not severe enough to interfere with daily life or independent function. People with mild cognitive impairment are at an increased risk of developing Alzheimer&rsquo;s disease.</span></p> <p><br /><span style="font-size: 10pt;">Study participants completed a questionnaire on the frequency and intensity of exercise during their lifetime. After following the participants for about three years, the researchers found that a history of moderate physical exercise in middle age was associated with a significantly decreased risk of mild cognitive impairment progressing to dementia. (The association did not hold for either light or vigorous exercise in middle age, or for any level of physical activity in late life.)</span></p> <p><br /><span style="font-size: 10pt;">In a second study reported at AAIC, the researchers looked at the timing of physical exercise and the risk of new cases of mild cognitive impairment. The study participants were 1,830 older adults with normal cognition from the Mayo Clinic Study of Aging. Participants underwent neurological evaluations, cognitive tests, and a self-reported questionnaire about physical exercise habits in mid-life and late-life, and were followed for an average of 3.2 years. The scientists observed that light physical exercise in mid-life and late-life were associated with decreased risk of incident mild cognitive impairment. Additionally, vigorous mid-life as well as moderate late-life physical exercise were associated with decreased risk of incident mild cognitive impairment.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;In our studies, we found that physical exercise at various levels, especially in mid-life, is beneficial for cognitive function,&rdquo; Geda says. &ldquo;These are intriguing results, but they are not yet conclusive. More research is needed to determine the extent and nature of physical activity in protecting against MCI and dementia.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />Poor sleep is associated with higher dementia risk in veterans; PTSD more than doubles that risk</strong></span></p> <p><br /><span style="font-size: 10pt;">It is known that sleep disturbance is a risk factor for cognitive decline and dementia, but this association has not been carefully investigated in older veterans. At AAIC 2014,&nbsp;Kristine Yaffe of the&nbsp;University of California, San Francisco&nbsp;and colleagues reported on the results of a retrospective study of sleep disturbance and dementia among 200,000 veterans age 55 and older, 96.5% of whom were male.</span></p> <p><br /><span style="font-size: 10pt;">The researchers examined eight years of the veterans&rsquo; medical records. After controlling for variables such as gender, income, education, and health status, they found that veterans who had a diagnosis of non-specific sleep disturbance, apnoea, or insomnia at baseline had a 30% increased risk of dementia compared with veterans with no diagnosed sleep problems. They also found that veterans with both PTSD and sleep disturbance had an 80% increased risk of dementia.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;This is the first investigation into the link between sleep disturbance and dementia in a large cohort of older, mostly male veterans,&rdquo; says Yaffe. &ldquo;Further research is needed to clarify the role of sleep disturbance as either a risk factor for, or an early symptom of, dementia among veterans, and in other populations as well.&rdquo;</span></p> <p><span style="font-size: 10pt;"><strong><br />In people 90 and older, late onset hypertension may protect against dementia</strong></span></p> <p><br /><span style="font-size: 10pt;">While hypertension during midlife is considered to increase risk for Alzheimer&rsquo;s and other dementia, there is emerging research evidence suggesting that its role in dementia risk may change over time, and may instead help protect against dementia in people age 90 and over, known as the &ldquo;oldest old.&rdquo;&nbsp;Maria Corrada of the&nbsp;University of California, Irvine&nbsp;and colleagues investigated the relationship between risk of dementia, age of the onset of hypertension, and blood pressure measurements in the oldest old, and reported the results at AAIC 2014.</span></p> <p><br /><span style="font-size: 10pt;">The researchers followed 625 participants every six months for up to ten years in The 90+ Study, an ongoing longitudinal study of people age 90 and older. At enrolment, participants did not have dementia and were 93 years old on average; 69% were female. The researchers found that participants with a hypertension onset age of 80 to 89 years had a significantly lower risk of developing dementia compared with participants with no history of hypertension. Participants with onset at age 90 or older had an even lower dementia risk.</span></p> <p><br /><span style="font-size: 10pt;">The investigators also found that people with blood pressure levels in the hypertensive range had a significantly lower risk of developing dementia compared to people with blood pressure in the normal range.&nbsp; The association was independent of whether participants were taking medications that treat hypertension.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;In our study, high blood pressure is not a risk factor for dementia in the oldest old, but just the opposite,&rdquo; says Corrada. &ldquo;Developing hypertension at older ages may be beneficial for maintaining intact cognition through mechanisms related to cerebral perfusion or to vascular or other pathologies. It is important to understand these mechanisms, because recommendations for healthy blood pressure in the oldest old may turn out to differ from those in younger people.&rdquo;</span></p></div> Cataract surgery improves not only vision but cognition and quality of life in dementia patients http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/cataract-surgery-improves-not-only-vision-but-cognition-and-quality-of-life-in-dementia-patients 2014-07-14T10:25:00Z 2014-07-14T10:25:00Z <div id="Introduction15" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Cataract surgery for people with Alzheimer&rsquo;s disease and other dementias not only improves vision but can slow decline in cognition and improve quality of life for both people with the disease and their caregivers, according to clinical trial results reported at the Alzheimer&rsquo;s Association International Conference&nbsp;2014 (AAIC) in&nbsp;Copenhagen, Denmark.</strong></span></p> </div><div id="Text115" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;This study supports the Alzheimer&rsquo;s Association view that people with dementia retain, and benefit from, full healthcare treatment,&rdquo; says&nbsp;Maria Carrillo, Alzheimer&rsquo;s Association vice president of Medical and Scientific Relations. &ldquo;Too common attitudes such as, &lsquo;There&rsquo;s no need for extra care&rsquo; or &lsquo;Why put them through all of that&rsquo; are not justified and are bad medical practice.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Appropriate thoughtfulness and restraint are necessary when considering surgery or other procedures for people with Alzheimer&rsquo;s or another dementia. However, we should not assume that medical procedures cannot be pursued or are too risky. As these new results show, improving sensory abilities, for example, can provide benefits in a variety of ways &ndash; for people with Alzheimer&rsquo;s and also for their caregivers from whom unnecessary burden can be lifted,&rdquo; Carrillo says.</span></p> <p><br /><span style="font-size: 10pt;">At AAIC 2014,&nbsp;Alan J Lerner, of&nbsp;Case Western Reserve University&nbsp;and University Hospitals Case Medical Center, and colleagues reported interim results from an ongoing clinical trial to determine the effects of cataract removal on several measures of visual ability, cognitive measures, and quality of life in people with dementia. Study participants are recruited from dementia and ophthalmology clinics at University Hospitals Case Medical Center and MetroHealth Medical Center in&nbsp;Cleveland, Ohio, USA, and are divided into two groups: (1) immediate surgery following recruitment and (2) delayed or refused surgery. Vision and cognitive status, mood, and capability to complete daily activities are evaluated at baseline and six months after recruitment, or six months after surgery.</span></p> <p><br /><span style="font-size: 10pt;">Preliminary analysis of results from 20 surgical and eight non-surgical participants showed that the surgical group had significantly improved visual acuity and quality of life, reduced decline in memory and executive functioning, and improvements in behavioural measures compared with the non-surgical group. Levels of perceived burden for caregivers of people in the surgical group also showed improvement.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;These preliminary results indicate that improved vision can have a variety of benefits for people with dementia and their loved ones, both visual and non-visual,&rdquo; says Lerner. &ldquo;Our findings need to be verified in a larger study, but they suggest the need to aggressively address dementia co-morbidities such as vision-impairing cataracts, while balancing safety and medical risks.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;If the results hold up, it will significantly affect how we treat cataracts in individuals with dementia. Other interventions to offset sensory loss &ndash; including vision and hearing &ndash; may help improve quality of life for people with dementia and their caregivers,&rdquo; Lerner adds.</span></p></div> New data shows combination therapy is more effective than monotherapy in removing beta-amyloid plaques from the brains of mice http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-data-shows-combination-therapy-is-more-effective-than-monotherapy-in-removing-beta-amyloid-plaques-from-the-brains-of-mice 2014-07-14T09:59:00Z 2014-07-14T09:59:00Z <div id="Introduction16" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Eli Lilly and Company has announced results from its non-clinical study in genetically engineered mice examining combination therapy with the murine version of the beta-amyloid antibody N3pG and beta-secretase inhibitor BACE (LY2811376). Data results found that combination therapy was more effective in removing clumps of amyloid-beta protein in the brain &ndash; a component that is thought to lead to Alzheimer&rsquo;s disease &ndash; than use of one therapy. These data were presented at the Alzheimer&rsquo;s Association International Conference 2014 (AAIC 2014) in&nbsp;Copenhagen, Denmark&nbsp;by&nbsp;Ron DeMattos, research fellow in the Neuroscience Division at Eli Lilly and Company.&nbsp;</strong></span></p> </div><div id="Text116" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;This non-clinical study demonstrates that by simultaneously targeting two different steps in the beta-amyloid disease process, researchers can slow the progression of Alzheimer&rsquo;s disease pathology in genetically engineered mice,&rdquo; says DeMattos. &ldquo;These results may have a significant impact on the future of Alzheimer&rsquo;s disease therapies as they support the clinical rationale for using future testing of combination therapy against the a-beta protein in the clinical practice.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Alzheimer&rsquo;s disease, the most common form of dementia, causes progressive decline in memory and other aspects of cognition. A number of new investigational mechanisms for the treatment of Alzheimer&rsquo;s disease are currently in development. One type of investigational mechanism, called beta-secretase inhibitors, aims to block the body&rsquo;s ability to produce beta-amyloid protein, a possible component that leads to Alzheimer&rsquo;s disease. The other type of investigational drug is called a beta-amyloid antibody, which targets the removal of the beta-amyloid protein. </span><span style="font-size: 10pt;">Compounds that are thought to work through these mechanisms have been studied in clinical trials on their own; however, most of the trials have not shown significant treatment effects. Therefore, many believe that multiple steps of the beta-amyloid deposition process need to be simultaneously targeted in order to remove significant quantities of the beta-amyloid pathology.</span></p> <p><br /><span style="font-size: 10pt;">The non-clinical study results showed that when used on their own (as monotherapies), the beta-secretase inhibitor and the N3pG beta-amyloid antibody removed approximately 50% of the clumps of amyloid-beta protein, whereas the combination therapy resulted in an even more substantial 86% removal. Additionally, combination therapy significantly lowered deposited A&beta;1-42 75 percent relative to the time zero controls. Histological analyses indicated that the BACE inhibitor monotherapy resulted in removal of diffuse deposits of beta-amyloid, the antibody monotherapy resulted in removal of cored plaques, and the combination therapy removed both the diffuse deposits and cored plaques. Multiple different types of biochemical analyses confirmed that the combination treatment was superior to the monotherapy treatments.&nbsp;</span></p> <p><span style="font-size: 10pt;"><strong><br />Study Methods<br /> <br /></strong>Aged PDAPP transgenic mice (17-19 months) were randomised into the following five cohorts: 1) time zero control, 2) large and small molecule compound controls, 3) plaque-specific A&beta; antibody (anti-A&beta;p3-x), 4) BACE inhibitor, and 5) A&beta; antibody + BACE inhibitor. The aged mice were treated for four months with either a beta-secretase inhibitor or the N3pG beta-amyloid antibody, or the combination of the two drugs. Effectiveness of the treatments was determined by measuring the amount of beta-amyloid protein remaining in the brains of the mice.</span></p></div> Post-concussion ‘return to play’ decision for footballers should be made solely by doctors, says new editorial http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/post-concussion-return-to-play-decision-for-footballers-should-be-made-solely-by-doctors-says-new-editorial 2014-07-14T09:47:00Z 2014-07-14T09:47:00Z <div id="Introduction17" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>An editorial published in <em><a href="http://www.thelancet.com/journals/laneur/issue/current" target="_blank">The Lancet Neurology</a>&nbsp;</em>calls for sports authorities to take into consideration the long-term neurological problems that repeated concussions can cause.</strong></span></p> </div><div id="Text117" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Cerebral concussion is the most common form of sports-related traumatic brain injury, and the long-term effects of repeated concussions may include dementia, amyotrophic lateral sclerosis, and other neurological disorders, say the journal editors.</span></p> <p><br /><span style="font-size: 10pt;">However, what is perhaps more concerning, is that even when the symptoms of concussion are delayed, or if they come and go quickly, neurological damage can remain without detection. This can lead to footballers, such as Uruguayan defender &Aacute;lvaro Pereira during the 2014 FIFA World Cup, overruling doctors&rsquo; advice to be substituted and returning to play after sustaining a head injury.</span></p> <p><br /><span style="font-size: 10pt;">The journal editors argue that the decision for players to return to a game after sustaining a concussion should be made only by healthcare professionals, and &ldquo;should surely be taken out of the hands of those with a vested interest in the player&rsquo;s performance.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">According to the journal editors, &ldquo;Many sporting organisations now acknowledge the potentially serious consequences of mild traumatic brain injury and have drawn up new protocols to protect athletes who sustain a head injury.

Stroke is a disease of the elderly predominantly, and so learning more about things that can influence risk for stroke as people age is important.&rdquo;</span></p> <p><span style="font-size: 10pt;">Researchers measured chronic stress in five domains: personal health problems, health problems of others close to the participant, job or ability to work, relationships and finances.</span></p> <p><br /><span style="font-size: 10pt;">They assessed depressive symptoms with a 20-question scale and analysed anger with a 10-item scale that captured the extent and frequency of experiencing that emotion.

He inserted a catheter in an artery in the groin, then guided the catheter up past the heart and through the carotid artery into the brain. Once the catheter reached the fistula, Ashley injected a liquid polymer that immediately solidified. This effectively sealed off the fistula to prevent a possible rupture.</span></p> <p><br /><span style="font-size: 10pt;">The case began when Abt consulted a physician about tinnitus (chronic ringing in his ear). The physician ordered a scan, which detected the arteriovenous fistula.</span></p> <p><br /><span style="font-size: 10pt;">Normally, arteries and veins are separate, with arteries transporting high-pressure blood from the heart to the body&rsquo;s organs, and veins carrying low-pressure blood back to the heart. But in Abt&rsquo;s case, an artery in his brain was directly connected to a vein. Consequently, high-pressure blood was shooting into the vein -- like a fire hose connected to a garden hose. The thin-walled vein, not designed to withstand such pressure, ballooned outward and was at risk of rupturing. Blood leaking from such a rupture could have caused a debilitating or fatal stroke.</span></p> <p><br /><span style="font-size: 10pt;">Christopher Loftus, chair of the Department of Neurological Surgery presented the case to a multidisciplinary cerebrovascular conference. Loftus led the discussion as physicians carefully examined the risks and benefits of all options, including traditional open surgery, the less-invasive endovascular treatment or no treatment at all. Loftus decided to bring Ashley in on the case.</span></p> <p><br /><span style="font-size: 10pt;">Abt underwent the less-invasive endovascular treatment on a Friday. He went home the next day, and began working from home the following week. The second week, he returned to work as senior vice president for administration and business at Carthage College in Kenosha, USA.</span></p></div> Treating oxygen-deprived newborns with hypothermia improves survival without brain damage in later childhood http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/treating-oxygen-deprived-newborns-with-hypothermia-improves-survival-without-brain-damage-in-later-childhood 2014-07-10T09:34:00Z 2014-07-10T09:34:00Z <div id="ImageMain24" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/treating-oxygen-deprived-newborns-with-hypothermia-improves-survival-without-brain-damage-in-later-childhood"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/028/baby_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction24" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>The cooling of newborn babies suffering from perinatal asphyxia &ndash; a lack of oxygen at the time of birth &ndash; significantly increases their chance of survival without brain damage to later childhood (age six to seven years), according to a Medical Research Council (MRC) funded clinical trial.</strong></span></p> </div><div id="Text124" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The study, published in the&nbsp;<a href="http://www.nejm.org/" target="_blank"><em>New England Journal of Medicine</em></a>, found that 51.7% of infants treated with hypothermia survived with an IQ of 85 or above, which is considered to be within the normal range, compared to 39.4% of those treated with standard care. Cooling significantly reduced the chance of oxygen-deprived children suffering from cerebral palsy and other moderate/severe disabilities. The children also showed improved motor functioning. However, the authors observed that there was no difference in mortality rate &ndash; reported to be around 30% of children enrolled in the trial &ndash; between the standard care and hypothermia-treated groups.</span></p> <p><span style="font-size: 10pt;"><br />The trial, led jointly by the National Perinatal Epidemiology Unit (NPEU) at the University of Oxford and Imperial College London, is the largest study of its kind and the first study to show improved brain function in children treated using this method in later life<strong>. </strong>Before this trial, there was limited information on the beneficial effect of cooling after asphyxia beyond the age of 18 months. This work is important because it demonstrates that the improvements observed in brain function are not just temporary.</span></p> <p><span style="font-size: 10pt;"><br />The <a href="https://www.npeu.ox.ac.uk/toby" target="_blank"><strong>MRC TOBY</strong></a> trial (Total body hypothermia) involved newborn babies of at least 36 weeks gestation that suffered from a lack of oxygen at birth. The children were randomly assigned into two groups within six hours of delivery, and either treated with standard care or standard care plus hypothermia, when their body temperature was reduced to 33.5˚C for 72 hours. After that time, they were slowly returned to a normal body temperature of 37˚C.</span></p> <p><span style="font-size: 10pt;"><br />The current research is part of the follow up <a href="https://www.npeu.ox.ac.uk/tobycs" target="_blank"><strong>TOBY Children Study</strong></a> that aimed to find out if there were any differences in the health of the children, treated with or without cooling, in later life. The scientists tested the children&rsquo;s mental abilities and performance at school, looked at parent and teacher reports on behaviour and investigated the presence and severity of any disabilities that resulted from oxygen deprivation.</span></p> <p><span style="font-size: 10pt;"><br />Following oxygen deprivation a number of processes are set off in the brain, which lead to brain cell death and permanent neurological damage. Hypothermia interrupts these processes to reduce brain injury and has consistently been shown to improve outcomes at 18 months. This study now confirms treatment with cooling is safe and effective, and that the benefits persist in the long term. The treatment has been endorsed by the National Institute for Health and Care Excellence (NICE) and adopted into clinical practice in the NHS; it has the advantage of being relatively simple and inexpensive to carry out.&nbsp;These new findings support its general use in neonatal clinical practice.</span></p> <p><span style="font-size: 10pt;"><br />Denis Azzopardi, of King&rsquo;s College London and lead author of the study, says: &ldquo;This study is important as it confirms improved brain function persisting into middle childhood with cooling treatment and it is a proof of the concept that treatment following oxygen deprivation at birth can be effective.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Brenda Strohm, research nurse and TOBY trial coordinator at the NPEU, University of Oxford, says: &ldquo;We are indebted to all the families who took part in the TOBY Trial and then the TOBY Children Study; their contribution to these two important studies has made a real difference to neonatal care.&rdquo;&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;While corresponding with the families over the years, I have shared many happy stories of achievement and success as well as moments of sadness and loss; this is a privilege which adds a special dimension to my role of study co-ordinator. Thanks to our latest research, now when a baby is treated with cooling, families can be more fully informed about what might lie ahead, not only in the coming months but in the next few years too.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Hugh Perry, chair of the MRC Neurosciences and Mental Health Board, says: &ldquo;This study is a great example of how research can change people&rsquo;s lives. Although major advances have been made in how childbirth is managed, approximately two out of every 1,000 newborn infants suffer from a lack of oxygen around the time of birth. Prior to the introduction of cooling therapy there were no approved, specific treatments that reduced the risk of brain injury long-term following asphyxia.<strong>&rdquo;</strong></span></p></div> Advances in trigeminal nerve stimulation featured at European congress on epileptology http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/advances-in-trigeminal-nerve-stimulation-featured-at-european-congress-on-epileptology 2014-07-09T14:49:00Z 2014-07-09T14:49:00Z <div id="Introduction25" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>NeuroSigma has announced top-line summaries of presentations made at the 11th European Congress on Epileptology in&nbsp;Stockholm, Sweden, related to the use of external trigeminal nerve stimulation (eTNS) in epilepsy.</strong></span></p> </div><div id="Text125" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Sean Slaght reported an update of observational findings in on-going adjunctive treatment with eTNS of adults at&nbsp;Kings College&nbsp;London, UK.&nbsp;In a group of 13 real-world, care-seeking patients with drug resistant epilepsy, who completed at least 12 weeks of nightly use of the Monarch eTNS system, they observed a median reduction in seizure frequency of 38%. The Kings College London researchers additionally reported on significant improvement in quality of life, mood, and sleep metrics.</span></p> <p><br /><span style="font-size: 10pt;">In the first-ever use of eTNS in paediatric patients with drug resistant epilepsy, Slaght reported preliminary findings on seven children, age 10 to 17, treated with this non-invasive, adjunctive therapy.

Brief magnetic pulses were used to assess cortical function before and after a course of treatment, in an effort to evaluate the mechanism of action of eTNS.&nbsp;&nbsp;Adam Pawley presented work conducted with Mark Richardson&nbsp;at Kings College London.&nbsp;Measures of cortical excitability consistently decreased with use of eTNS, implicating potential effects on signalling in both GABA<sub>A</sub>- and GABA<sub>B</sub>-mediated circuits.

The acute procedural performance of the CGuard device was 100% successful for all of the 30 patients enrolled in the trial.</strong></span></p> </div><div id="Text127" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Thirty patients were enrolled at four sites across Europe and will be followed up using traditional assessments post-procedure and at 30 days to include MACE (death, stroke, MI), and ipsilateral stroke (31 days to one year).&nbsp; In addition, DW-MRI (Diffusion Weighted Magnetic Resonance Imaging) is being done pre and post procedure and at 30 days, as well as ultrasound examination at 30 days and one year on every patient.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The proprietary CGuard carotid embolic protection system uses the same MicroNet technology featured on the MGuard and MGuard Prime coronary embolic protection systems. The MicroNet technology is a single fibre knitted mesh wrapped on an open cell stent platform designed to trap debris that can dislodge and travel downstream after a patient is treated with traditional stenting methods. This technology seeks to protect patients from plaque debris and blood clots breaking off and which can lead to life threatening strokes. The size, or aperture, of the MicroNet &rsquo;pore&rsquo; is only 150-180 microns in order to maximise protection against the potentially dangerous plaque and thrombus within the carotid artery.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;I am excited that enrolment in the CGuard CARENET study has just been completed. I have treated many patients with carotid artery disease over the years and the unique CGuard embolic protection system with MicroNet has changed the way I think about treating these challenging patients,&rdquo; states Joachim Schofer, from the Hamburg University Cardiovascular Center, in Hamburg, Germany. &ldquo;The experience that we have gained using the CGuard device has given us a sense of confidence in regards to new technology options when treating these patients. The small pore size of the MicroNet technology allows excellent blood flow while trapping potentially harmful plaque debris and thrombus. The CGuard technology provides an elegantly simple solution for embolic protection that has not been available in the past. I look forward to reviewing and analysing all of the CARENET data over the next several weeks and sharing the results soon afterward.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The completion of the CGuard CARENET trial on schedule with 100% procedural success rate is an important milestone for InspireMD,&rdquo; states Alan Milinazzo, president and chief executive officer of InspireMD, &ldquo;Our investigators have done a wonderful job throughout this trial, and their feedback on the CGuard has been very positive and informative. The initial results support our belief that the MicroNet technology may deliver life-saving benefits to patients with carotid artery disease and revolutionise the way the carotid stenting procedures are performed. We are looking forward to analysing the data from the CARENET trial and sharing the results in mid-September at the upcoming TCT conference.&rdquo;</span></p></div> SMC says yes to Lemtrada 12mg IV for adults with active relapsing-remitting multiple sclerosis http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/smc-says-yes-to-lemtrada-12mg-iv-for-adults-with-active-relapsing-remitting-multiple-sclerosis 2014-07-08T10:56:00Z 2014-07-08T10:56:00Z <div id="ImageMain28" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/smc-says-yes-to-lemtrada-12mg-iv-for-adults-with-active-relapsing-remitting-multiple-sclerosis"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/038/Lemtrada_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction28" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>The Scottish Medicines Consortium (SMC) has published its advice that Lemtrada has been accepted for use within NHS Scotland for the treatment of adult patients with relapsing-remitting multiple sclerosis (RRMS), with active disease defined by clinical or imaging features.</strong></span></p> </div><div id="Text128" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;RRMS accounts for 85% of all initial diagnoses in multiple sclerosis.

The research is the result of an international collaboration involving Proteome Sciences and funded by Alzheimer&rsquo;s Research UK, the MRC and NIHR Maudsley Biomedical Research Centre. The study is published on 8 July in the journal <a href="http://www.alzheimersanddementia.org/" target="_blank"><em>Alzheimer&rsquo;s and Dementia</em></a>.</strong></span></p> </div><div id="Text129" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">There is currently a large focus in the research community on developing simple and accurate tests that could detect Alzheimer&rsquo;s early or predict who may go on to develop the disease. Alzheimer&rsquo;s changes are known to start in the brain 10 to 15 years before symptoms show and so detecting the disease early could give new treatments the best chance of success.</span></p> <p><br /><span style="font-size: 10pt;">Simon Lovestone, now at Oxford University, and his team studied blood samples from 1,148 volunteers. Of the participants, 452 did not have dementia, 476 had Alzheimer&rsquo;s and 220 had mild cognitive impairment (MCI). Mild cognitive impairment is a term used to describe early memory and thinking problems, which do not necessarily lead onto Alzheimer&rsquo;s, but can put people at a higher risk of the disease. Some of the volunteers also had brain scans to look for tell-tale signs of Alzheimer&rsquo;s in the brain.</span></p> <p><br /><span style="font-size: 10pt;">The researchers analysed blood samples from the volunteers for 26 proteins previously linked to Alzheimer&rsquo;s disease. They found that several of these proteins associated with brain shrinkage on brain scans in people with mild cognitive impairment and Alzheimer&rsquo;s. Taking their research a step further, the team investigated whether any of the proteins could predict the progression from mild cognitive impairment to Alzheimer&rsquo;s. They discovered a panel of 10 proteins that were able to predict which volunteers with mild cognitive impairment would go on to develop Alzheimer&rsquo;s within a year.</span></p> <p><br /><span style="font-size: 10pt;">Abdul Hye, lead author of the study from the Institute of Psychiatry at King&rsquo;s College London, says: &ldquo;Memory problems are very common, but the challenge is identifying who is likely to develop dementia. There are thousands of proteins in the blood, and this study is the culmination of many years&rsquo; work identifying which ones are clinically relevant. We now have a set of 10 proteins that can predict whether someone with early symptoms of memory loss, or mild cognitive impairment, will develop Alzheimer&rsquo;s disease within a year, with a high level of accuracy.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Simon Lovestone, senior author of the study from the University of Oxford, who led the work whilst at King&rsquo;s, says: &ldquo;Alzheimer&rsquo;s begins to affect the brain many years before patients are diagnosed with the disease. Many of our drug trials fail because by the time patients are given the drugs, the brain has already been too severely affected. A simple blood test could help us identify patients at a much earlier stage to take part in new trials and hopefully develop treatments which could prevent the progression of the disease. Our next step will be to test our findings in even larger sample sets, to further improve accuracy and reduce the risk of misdiagnosis, before we can develop a reliable test suitable to be used by doctors.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Eric Karran, director of Research at Alzheimer&rsquo;s Research UK, the UK&rsquo;s leading dementia research charity, says:</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;As the onset of Alzheimer&rsquo;s is often slow and subtle, a blood test to identify those at high risk of the disease at an early stage would be of real value. Detecting the first signs of Alzheimer&rsquo;s could improve clinical trials for new treatments and help those already concerned about their memory, but we are not currently in a position to use such a test to screen the general population.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;It is promising to see research taking us closer to mapping the first changes in Alzheimer&rsquo;s, and the team has pooled data from different studies worldwide to bolster their findings. Many people with mild cognitive impairment will not go on to develop Alzheimer&rsquo;s, but the proteins identified in this panel could help researchers to understand the biology driving the disease in those who do. However, with the risk of misdiagnosis from this panel still high, we would need to see such a test well validated and repeated before it could be used in the clinic.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;With an ageing population, and age the biggest risk factor for Alzheimer&rsquo;s, we are expecting rising numbers of people to be affected over the coming years. It is important to develop new ways to intervene early in the disease to help people maintain their quality of life for as long as possible.&rdquo;</span></p></div> New surgical tool provides hope for patients with inoperable deep bleeding in the brain http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-surgical-tool-provides-hope-for-patients-with-inoperable-deep-bleeding-in-the-brain 2014-07-07T10:15:00Z 2014-07-07T10:15:00Z <div id="ImageMain30" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-surgical-tool-provides-hope-for-patients-with-inoperable-deep-bleeding-in-the-brain"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/040/Apollo_system_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction30" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>The Apollo system, manufactured by Penumbra, has been widely launched following first-in-man clinical use at leading US hospitals.</strong></span></p> </div><div id="Text130" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">According to Penumbra, Apollo is an innovative new surgical tool that enables minimally invasive removal of deeply seated tissue and fluids in the brain during a single, efficient operation. With combined use of an endoscope and image guidance, the Apollo system allows decompression and removal of otherwise inoperable blood clots deep in the brain, among other uses.</span><br /> <br /><span style="font-size: 10pt;"> Alexander Khalessi, assistant professor of surgery and neurosciences at UC San Diego Medical Center and surgical director of Neurocritical Care, successfully treated the first patient in the world using the Apollo device. Khalessi explains: &ldquo;Our first patient was a 41-year-old male who suffered a spontaneous bleeding deep in his brain that completely shifted his ventricular system, interrupted fluid circulation and compressed his midbrain. Despite standard measures including a ventricular catheter to drain fluid, the overall pressure in his brain was not well controlled. Of greater urgency, the patient was essentially comatose with a fixed downward gaze consistent with a Parinaud&rsquo;s syndrome. With evidence of midbrain compression and this clinical sign, we knew this gentleman was at risk for time-sensitive, irreversible damage to the connection between his brain and body.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Large, decompressive open surgeries for this condition are not supported in the published data. Ongoing research efforts include a trial exploring minimally invasive approaches that involve the implantation of a small catheter with gradual removal of the clot over many days. For my patient, I was concerned his need was more urgent, and that the Apollo system would facilitate the same surgical result in minutes, rather than days.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Following successful clot removal with the Apollo system, our patient&rsquo;s gaze improved and we were able to remove brain pressure monitors and breathing support within 48 hours. As opposed to facing several weeks comatose in the intensive care unit, our patient was transferred to the hospital floor, was able to talk to his family, and has since transitioned to a rehabilitation facility.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;This initial success led to our use of Apollo in a second, 51-year-old patient with a massive haemorrhage; Apollo facilitated complete removal through a small incision in the eyebrow. He left the intensive care unit within 24 hours and like our first patient, went from a near fatal situation in the hospital, to quickly beginning his recovery in a rehabilitation facility.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;I remain hopeful we are finally making progress in an all too common and horribly disabling and fatal disease,&rdquo; Khalessi concludes.</span></p> <p><span style="font-size: 10pt;"><br />Demetrius Lopes, section chief of Cerebrovascular Neurosurgery at Rush University Medical Center in Chicago, USA, is also an early user. &ldquo;I think the arrival of the Apollo system is very timely. We have had great initial experience in removing intraventricular blood. Use of the Apollo system has resulted in faster patient recovery and a shortened stay in the intensive care unit,&rdquo; explains Lopes.</span></p> <p><br /><span style="font-size: 10pt;">David Fiorella, professor of Clinical Neurological Surgery and Radiology at Stony Brook University Medical Center, discussed his view on the value of the Apollo system and compared it to alternative techniques. &ldquo;Our team at Stony Brook has had tremendous success thus far using the Apollo system, in conjunction with neuroendoscopy and image guidance, for the removal of haemorrhages in the brain. This technique has the potential to be a truly important advance for our field, since no other treatment has convincingly been shown to help patients with this lethal disease. Usually patients with this type of haemorrhagic stroke have very poor outcomes and extremely long hospital stays. Just hours after treatment, our patients began showing improvement, and they continued to improve rapidly during their hospital stays.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;While we were very pleasantly surprised by our patients&rsquo; impressive clinical responses, some data indicates that these types of outcomes might be expected. The investigators in the Minimally invasive surgery and tPA in ICH evacuation (MISTIE II) trial found that when they achieved near complete removal of blood clots (to less than 10 millilitres remaining), they observed higher rates of good clinical outcomes. However, this degree of clot reduction was not achieved in most patients. In addition, with the MISTIE technique, clot reduction required several days of drainage through a small catheter left in place after surgery. With the new Apollo system, it seems that we may be able to achieve the desired level of clot reduction immediately and safely in most patients. Therefore, it is possible that we will continue to observe clinical benefits that surpass our former expectations.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;While these early results are certainly impressive and give us enthusiasm going forward,&nbsp;it is important to recognise that we are very early on in our experience with this procedure. Much more data will be required before we know exactly how effective it is and which patients will benefit most,&rdquo; Fiorella comments.</span></p> <p><br /><span style="font-size: 10pt;">The Apollo system is the result of decades of research and development work in the field of advanced aspiration and vibrational energy technology by researchers at Penumbra. Advanced aspiration technology was first developed and perfected in the field of acute ischaemic stroke where blood clots inside the arteries of the brain are starving brain tissue of vital oxygen and nutrients. The Apollo system adds internal energy generation to a specialised advanced aspiration tool to surgically address deep bleeding in the brain, a particularly devastating form of acute haemorrhagic stroke.</span></p></div> New results show personalised brain tumour vaccine helps patients live longer http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-results-show-personalised-brain-tumour-vaccine-helps-patients-live-longer 2014-07-07T09:53:00Z 2014-07-07T09:53:00Z <div id="Introduction31" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Patients newly diagnosed with glioblastoma multiforme (GBM) and treated with an experimental cancer vaccine made from the patient&rsquo;s own tumour in addition to standard of care lived longer compared to those who received standard of care alone, according to new results from a study involving Northwestern Medicine researchers and released on 1&nbsp;July.</strong></span></p> </div><div id="Text131" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Glioblastomas are fast growing tumours that invade normal brain tissue. The disease is often resistant to treatments such as chemotherapy and radiation and median survival is approximately 15 months from the point of first diagnosis.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Improving the survival for GBM patients is an important goal for many of us here at&nbsp;Northwestern,&rdquo; says the study&rsquo;s principal investigator&nbsp;Andrew Parsa, who is chair of neurological surgery at&nbsp;Northwestern Memorial Hospital&nbsp;and the Michael J Marchese professor and chair of the&nbsp;department of neurological surgery&nbsp;at&nbsp;Northwestern University Feinberg School of Medicine. &ldquo;This brain cancer does not discriminate. It affects all ages, genders and races and less than 5% of glioblastoma patients survive five years. With new research and studies like this, we hope to one day write a different ending to the story by turning this into a chronic disease &ndash; one that can be treated with medication.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Typically, patients newly diagnosed with a glioblastoma undergo surgery to remove their tumour followed by radiation and temozolomide, an oral chemotherapy drug. This phase 2 single-arm trial consisted of 46 patients and added a vaccine made from their tumour to their treatment. The vaccine is unique to each patient and is engineered to trigger an immune system response to kill tumour cells that may remain following surgery. &nbsp;&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Results showed the patients who added the vaccine to their treatment lived longer. More specifically, 50% of the patients enrolled in the trial lived for two years, an encouraging result for a cancer that often kills patients within one year. The patients enrolled in this trial were treated at eight centres across the USA including Northwestern Memorial.</span></p> <p><br /><span style="font-size: 10pt;">Median overall survival for patients enrolled in the trial is 23.8 months. For the standard of care alone, median overall survival rate is 14.6 months. The trial also monitored each patient&rsquo;s progression-free survival, which is the length of time a patient lives with the tumour controlled. Vaccine treated patients had a median progression-free survival of nearly 18 months, approximately two- to three-times longer than patients treated with radiation and temozolomide alone.<sup>&nbsp;&nbsp;</sup>In addition, 22% of patients enrolled in the trial were alive at 24 months and continue to be monitored. &nbsp;</span></p> <p><br /><span style="font-size: 10pt;">Based on the positive phase 2 trial results, Agenus Inc, the biopharmaceutical company&nbsp;developing the vaccine, is exploring partnerships for a randomised, phase 3 trial. A successful trial could lead to the vaccine potentially being approved to treat brain tumours, making it one of only a few approved therapeutic cancer vaccines and treatments for GBM patients.&nbsp;&nbsp; &nbsp;</span></p> <p><br /><span style="font-size: 10pt;">While new findings such as this one continue to extend the lives of patients with glioblastoma, for the moment, it remains one of the most dreaded diagnoses, which is why Parsa, co-leader of the Translational Research in Solid Tumours Programme at the&nbsp;Robert H Lurie Comprehensive Cancer Center of Northwestern University, and other Northwestern Medicine researchers are also studying&nbsp;the vaccine for GMB patients whose tumour returns. &nbsp;The phase 2 recurrent and newly diagnosed trials are being led by Parsa and primarily have been supported through funding from the American Brain Tumor Association, Accelerated Brain Cancer Cure, National Brain Tumor Society and National Cancer Institute Special Programs of Research Excellence.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;A glioblastoma is the most common primary malignant brain tumour and affects up to 17,000 Americans annually,&rdquo; says&nbsp;Jeffrey Raizer, co-director of the Northwestern Brain Tumor Institute, director of medical neuro-oncology at the Lurie Cancer Center and the principal investigator for the study at Northwestern Memorial. &ldquo;Vaccine therapy has the potential to offer a safer and less toxic cancer treatment to patients. While conventional therapies sometimes cause debilitating side effects, this treatment is simply a series of injections that is increasing the survival of patients in early trials.&nbsp;Importantly, it can be combined with other therapies allowing us to attack these tumours from different approaches.&rdquo;</span></p></div> Mazor Robotics receives first order for Renaissance system with brain module http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/mazor-robotics-receives-first-order-for-renaissance-system-with-brain-module 2014-07-07T09:37:00Z 2014-07-07T09:37:00Z <div id="ImageMain32" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/mazor-robotics-receives-first-order-for-renaissance-system-with-brain-module"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/008/Renaissance_Mazor-Robotics_Main.gif" border="0" vspace="5" /></a></div><div id="Introduction32" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Mazor Robotics has announced that it has received the first order for its Renaissance system since the commercial launch of the brain surgery module.</strong></span></p> </div><div id="Text132" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The system was sold to Bryan Medical Center in Lincoln, Nebraska, USA and will be utilised for spine and brain procedures.

And for people with brain injury, disease or in need of deficit recovery and maintenance, Brain+ prioritises cognitive abilities to assist in either returning to a normal life or stabilising or even improving a range of deficits.</span><br /> <br /><span style="font-size: 10pt;"> According to a company release, Brain+ is designed to deliver better performance results than other entrants in the brain-training market, which lack strength in scientific foundation and effect, and are locked into sterile, non-motivating models of test exercises. Specifically, Baden-Kristensen says, earlier entrants in the space fail to motivate users over the long term by properly engaging and captivating them due to a lack of gamification best practices, which Brain+ employs in its games.</span><br /> <br /><span style="font-size: 10pt;"> Because Brain+ develops exercises that closely resemble state-of-the art mobile games, the production value, art quality and design requirements are all high, thereby paving the way for unique training experiences, mimicking the entertainment provided by traditional mobile games while maintaining an emphasis on strengthening brain functions.</span><br /> <br /><span style="font-size: 10pt;"> Baden-Kristensen said Brain+ has feedback from many users who say they can feel the app makes a demonstrable difference in their lives because it&rsquo;s fun, engaging, less of a chore to give their brains a workout and drives a desire to share the challenge of their brain exercises with friends and family members.&nbsp;</span></p> <p><span style="font-size: 10pt;">Brain+&nbsp;has invested heavily in the development of a science-based, machine-learning algorithm and technology that challenges the user dynamically and with high precision according to the skills of the individual. </span><br /> <br /><span style="font-size: 10pt;"> <strong>Recommended by Benjamin Sadock</strong></span><br /> <br /><span style="font-size: 10pt;"> &ldquo;The Brain+ project provides a unique and well-proven approach to improve brain function,&rdquo; says Benjamin Sadock, the Menas S Gregory professor of Psychiatry at the New York University School of Medicine. &ldquo;The programme combines new scientific knowledge about how the brain works with the latest advances in gaming techniques to train the brain to operate at its maximum capacity.</span><br /> <br /><span style="font-size: 10pt;"> &ldquo;The use of characters, action, movement, music and immediate feedback allows brain fitness to occur in an environment that is both playful and entertaining. Brain+ will be of use to both healthy adults and those with memory problems who wish to improve their cognitive skills,&rdquo; Sadock says.&nbsp; &ldquo;This is an exciting programme that will continually motivate and stimulate the user to gain new skills and greater confidence in his or her intellectual life. I recommend it most highly.&rdquo;</span><br /> <br /><span style="font-size: 10pt;"> Brain+ has already demonstrated proof of concept by achieving rapid growth in parts of Europe, Asia, Africa and Australia.</span></p></div> electroCore&apos;s funding US$10 million oversubscribed by all parties http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/electrocores-funding-us10-million-oversubscribed-by-all-parties 2014-07-02T11:52:00Z 2014-07-02T11:52:00Z <div id="ImageMain35" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/electrocores-funding-us10-million-oversubscribed-by-all-parties"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/gammaCore_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction35" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>electroCore has announced that its successful funding initiative of US$40 million, announced in April last year, has been oversubscribed by US$10 million by all parties including Merck&rsquo;s Global healthcare Innovation fund and private equity groups Easton Capital and Core Ventures. The final tranche of US$15 million of the US$40 million was optional but following discussions between the investors this was not only made compulsory but increased by US$10 million to a total of US$50 million.</strong></span></p> </div><div id="Text135" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">electroCore has developed and patented a non-invasive vagus nerve stimulation (nVNS) therapy for the treatment of a variety of conditions in neurology, psychiatry, gastroenterology and other conditions.</span></p> <p><span style="font-size: 10pt;"><br />Its focus, at present, is primary headache - cluster and migraine - where it is just concluding four randomised studies in Europe and the USA. The European randomised PREVA study, for the prevention and acute treatment of chronic cluster headache, last week achieved statistical significance on its primary endpoint by reducing the number of cluster headache attacks per week by 47.5% in patients treated with nVNS compared to 12.1% in patients treated with the best available standard of care.</span></p> <p><span style="font-size: 10pt;"><br />In Europe, the nVNS technology, as delivered by electroCore&rsquo;s gammaCore device is considered CE markable, and a CE mark has been awarded in primary headache, bronchoconstruction, epilepsy, gastric motility disorders and depression and anxiety. In the US the pivotal trial for headache is just finishing and an application for a US license will follow.</span></p> <p><span style="font-size: 10pt;"><br />Surgically implanted vagus nerve stimulation (VNS) has been proven for more than twenty years, and in more than 100,000 patients, to be an effective and safe therapy for the treatment of refractory epilepsy and depression but because of its high cost and invasiveness it has been relegated to the end of the continuum of care.</span></p> <p><span style="font-size: 10pt;"><br />JP Errico chief executive officer and founder comments: &ldquo;It has been known for years that vagus nerve stimulation relieved a whole variety of conditions including headache, bronchoconstruction, and many other symptoms but because of its US$30,000 cost it was not considered. We believe that we have revolutionised this effective treatment by proving that our inexpensive nVNS therapy is just as effective as surgically implanted and can be used by millions of patients to self-treat their particular condition. Our nVNS therapy does one thing, it reduces the over expression of the excitatory neurotransmitter glutamate which has been implicated in a number of these disorders. This appears to be born out from the very encouraging signals we are getting from our clinical programme in headache as well as observational and open label studies across a number of these conditions.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />At the Royal Free Hospital in London the company is running a double-blind, parallel, sham controlled trial in patients with two of the most common gastrointestinal complaints; Irritable Bowel Syndrome and functional dyspepsia. This follows a successful proof of concept assessment in patients with gastroparesis. &nbsp; &nbsp;&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />electroCore is involved in clinical trials in universities across Europe and plans to extend this to the US after receiving FDA approval.</span></p></div> Agenus brain cancer vaccine shows extended survival in phase 2 final data analysis http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/agenus-brain-cancer-vaccine-shows-extended-survival-in-phase-2-final-data-analysis 2014-07-02T11:23:00Z 2014-07-02T11:23:00Z <div id="Introduction36" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Agenus&nbsp;has announced final results from a single-arm, multi-institutional, open-label, phase 2 study showing that patients with newly diagnosed glioblastoma multiforme (GBM) who received Agenus&rsquo; Prophage autologous cancer vaccine added to the standard of care treatment, lived nearly twice as long as expected.</strong></span></p> </div><div id="Text136" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">In this phase 2 study, 50% of the patients lived for two years, an encouraging result for a cancer that often kills patients within one year. Prophage patients demonstrated a median overall survival of approximately 24 months and 33% of patients remain alive at two years and continue to be followed for survival.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;These data suggest that Prophage is generating an effective immune response which is translating into an extension in survival far beyond what is historically seen in patients with glioblastoma multiforme. These data provide the impetus for a definitive, randomised clinical trial,&rdquo; says&nbsp;Andrew Parsa, principal investigator of the study and the Michael J Marchese professor and chair of the&nbsp;Department of Neurological Surgery&nbsp;at the Feinberg School of Medicine at Northwestern University. &ldquo;Glioblastoma tumours are often resistant to standard therapies and the extended progression-free survival and proportion of long-term survivors is very encouraging.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">In addition to the long-term survival data, vaccine treated patients had a median progression-free survival (PFS) of nearly 18 months, approximately two to three-times longer than patients treated with radiation and temozolomide alone. Importantly, 22% of patients were alive and without progression at 24 months and continue to be followed for survival.</span></p> <p><br /><span style="font-size: 10pt;">Interestingly, the response to Prophage seems to be more pronounced in those patients with less expression of the checkpoint ligand PDL-1 on the white blood cells, suggesting that combinations of Prophage with checkpoint modulators like PD-1 antagonists might make Prophage even more effective in a greater percentage of patients with glioblastoma multiforme.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;We believe that Prophage may play an important role in changing the treatment paradigm for patients with glioblastoma multiforme,&rdquo; says Garo Armen, chief executive officer and chairman of Agenus. &ldquo;We are exploring partnerships for phase 3 studies of Prophage in glioblastoma multiforme. Additionally, we are excited about the potential combinations of Prophage with PD-1 antagonists and other checkpoint modulators in glioblastoma multiforme.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Prophage is an autologous cancer vaccine, and each patient receives vaccine prepared from their own surgically resected tumour. As a result, the vaccine appears to help stimulate the patient&rsquo;s immune system to attack the tumour based on the spectrum of mutant proteins expressed by their own tumour. Since most cancers result from an accumulation of random mutations, which produce different mutant proteins in each patient, this approach is intended to individually tailor each patient&rsquo;s vaccine to optimally target the immune attack to that patient&rsquo;s actual tumour.</span></p></div> Scotland’s National Epilepsy Centre reports 100% success rate in first year http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/scotlands-national-epilepsy-centre-reports-100-success-rate-in-first-year 2014-07-02T11:13:00Z 2014-07-02T11:13:00Z <div id="Introduction37" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A new national centre of excellence for the treatment of epilepsy in Scotland, which integrates health care with social care, has recorded a 100% success rate in its first year.</strong></span></p> </div><div id="Text137" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The William Quarrier Scottish Epilepsy Centre (WQSEC), a not-for-profit partnership between charity Quarriers and the NHS, welcomed 96 patients in the 12 months after opening in April 2013, its first annual report has revealed.</span></p> <p><br /><span style="font-size: 10pt;">During 2013/14 the centre enjoyed a 100% success rate in transforming lives through accurate diagnosis, including being more accessible for people with disabilities (27% of patients).</span></p> <p><br /><span style="font-size: 10pt;">A devastating, sometimes fatal, neurological condition, it is expected more than 2,000 Scots will this year be told they have epilepsy. The WQSEC has capacity to accommodate up to 170 patients annually while over the lifetime of the building the centre will transform more than 10,000 lives and reduce deaths.</span></p> <p><br /><span style="font-size: 10pt;">The first anniversary of the WQSEC was marked with a special patient celebration event attended by around a third of those admitted to the centre during its first year.&nbsp;</span></p> <p><br /><span style="font-size: 10pt;">Gerard Gahagan, head of Epilepsy Services at WQSEC, says: &ldquo;We are extremely proud of what has been achieved in our first year, with the voluntary sector and NHS working together so effectively to deliver a world-class centre of excellence.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;While patients benefit from clinical innovation, quality of care, and long-term improvements leading to better lives, health boards have experienced reduced waiting lists, a reduced drugs bill and less pressure on Accident &amp; Emergency, inpatient beds and outpatient clinics.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;What sets the WQSEC apart, however, is the ability to diagnose the most complex cases; those that are particularly severe, or where there are issues that complicate diagnosis such as disabilities or psychological problems. This ability has been taken to a new level with our new, world-leading Video Observation System diagnostic technology and the design features of the new building itself.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;These capabilities have attracted significant interest from European clinicians who consider the WQSEC to be a model they could replicate across the continent. The fact that Scotland hosts this centre of excellence is being noticed internationally and there are opportunities for research of international significance.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">He adds: &ldquo;For so many of our patients to return to join in a celebration is a demonstration of the centre&rsquo;s people-centred approach and strong patient participation and engagement.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">The WQSEC is also improving knowledge and understanding of epilepsy, with more than 450 medical students now being trained at the centre throughout the year.&nbsp; The centre and its team has hosted an international conference &ndash; Challenging Epilepsy &ndash; attended by 100 practitioners, pioneered a research programme with the University of Glasgow and chaired the government&rsquo;s National Neurological Advisory Group Epilepsy team. It also has outreach services which help people across the country while epilepsy awareness days have been organised at for companies and public sector bodies.</span></p> <p><br /><span style="font-size: 10pt;">Importantly, another of WQSEC&rsquo;s key objectives has been met with a marked increase in admissions from outwith West of Scotland reflecting the national status. Since opening, patients being referred to the centre from other parts of Scotland now represent 39% of all admissions, compared with 30% last year and 25% the year before (to the previous facility).</span></p> <p><br /><span style="font-size: 10pt;">Reasons for referral are as follows:</span><br /><br /></p> <p><span style="font-size: 10pt;">&middot;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; To clarify diagnosis &ndash; 68%</span></p> <p><span style="font-size: 10pt;">&middot;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; To review medication &ndash; 13%</span></p> <p><span style="font-size: 10pt;">&middot;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; To clarify seizures &ndash; 13%</span></p> <p><span style="font-size: 10pt;">&middot;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; For video-telemetry only &ndash; 3%</span></p> <p><span style="font-size: 10pt;">&middot;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; To investigate sleep issues &ndash; 3%</span><br /><br /></p> <p><span style="font-size: 10pt;">Diagnoses found that 49% of patients had epilepsy, 27% had non-epileptic seizures while 24% had a complex mixture of both epileptic and non-epileptic seizures which can be very difficult to diagnose. With these diagnoses, the WQSEC is able to provide treatment tailored to each individual, improving seizure control, or reducing the powerful side-effects of drugs by rationalising medication. In every case, treatment radically increases quality of life, while in many cases, it is life-saving.</span></p> <p><br /><span style="font-size: 10pt;">Bill Scott, Patron of the Scottish Epilepsy Centre, says: &ldquo;Having finished the construction of the William Quarrier Scottish Epilepsy Centre, it could be tempting to sit back in satisfaction with a job well done. However, 54,000 Scots live daily with this cruel condition. Lives continue to be shattered by epilepsy and the social and economic cost is huge.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The WQSEC was conceived and designed to meet this crisis. With the completion of the WQSEC, Quarriers has not only the platform, but indeed an obligation to strive to improve outcomes for all people with epilepsy in Scotland.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;With its world-class facilities, European treatment and diagnostic leadership the WQSEC will certainly transform hundreds of lives each year. We will use this as a catalyst which, combined with policy influencing, research and training programmes, will contribute to the delivery of improved life-changing services to tens of thousands in Scotland and beyond.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;In this way, the WQSEC is not the end of our ambition. In fact, it&rsquo;s just the beginning.&rdquo;</span></p></div> Omega-3 fats may significantly reduce damage from stroke http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/omega-3-fats-may-significantly-reduce-damage-from-stroke 2014-07-02T10:54:00Z 2014-07-02T10:54:00Z <div id="ImageMain38" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/omega-3-fats-may-significantly-reduce-damage-from-stroke"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/039/Omega_3_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction38" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>New evidence shows that the&nbsp;omega-3 polyunsaturated fatty acids (PUFAs) found in seafood and marine oils,&nbsp;DHA&nbsp;and&nbsp;EPA, can significantly reduce damage from stroke in a mouse model when given immediately afterwards. Moreover, DHA and another PUFA demonstrate a positive effect on neurocognitive function in children.

Ischaemic stroke, caused by a blockage of a blood vessel that supplies blood to the brain, accounts for about 87% of all cases. Investigators at&nbsp;Goethe University&nbsp;of&nbsp;Frankfurt, Germany, explored ischaemic stroke in mice and the impact of an EPA and DHA emulsion administered 90 minutes afterwards, by examining the degree of damage, cellular function and neuroinflammation.</span></p> <p><span style="font-size: 10pt;"><br />Treatment with the omega-3 emulsion significantly decreased the stroke area by 21% and lowered the severity of stroke by 50%. It also significantly improved brain cell function and reduced markers of inflammation.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;This pilot study demonstrated that DHA and EPA might aid in early medical intervention in ischaemic stroke,&rdquo; says&nbsp;Gunter Eckert, associate professor of pharmacology and toxicology at Goethe. &ldquo;Further investigation is in order and holds promise for human trials.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />DHA&rsquo;s involvement in recovery from stroke was also explored by&nbsp;Nicolas Bazan, professor and director, Neuroscience Center of Excellence,&nbsp;Louisiana State University Health Sciences Center,&nbsp;New Orleans, USA. DHA encourages the production of special substances that allow for cell survival under excessive stress, neurodegeneration or ischaemic stroke.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;These substances are increased by DHA after ischaemic stroke in animals, followed by remarkable neurological recovery,&rdquo; notes Bazan.</span></p> <p><span style="font-size: 10pt;"><br />The benefits of DHA in brain health have also been demonstrated in humans.&nbsp;Kathleen Gustafson, research assistant professor,&nbsp;University of Kansas Medical Center,&nbsp;Kansas City,&nbsp;USA, and colleagues investigated the effect of DHA and arachidonic acid (ARA), an omega-6 PUFA, on response inhibition in a follow-up study of 54 term infants randomised to receive formula with or without PUFAs from birth to 12 months. At roughly 5.5 years, children participated in a go/no-go task requiring rule learning and inhibitory control.

The SNAP integrates with operating room technology to provide advanced 3D capabilities and augmented reality, allowing surgeons to enhance their surgery performance and &ldquo;see what cannot be seen&rdquo;.</strong></span></p> </div><div id="Text139" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The SNAP is the second of the company&rsquo;s line of products combining flight simulation technology with advanced CT/MRI imaging for use in brain surgery to receive FDA clearance. It enables surgeons to perform a real-life &ldquo;fly through&rdquo; of a &ldquo;patient-specific&rdquo; surgery and receive unique virtual-reality guidance to determine the safest and most efficient pathway to remove cerebral tumours and treat vascular anomalies.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />With the SNAP, surgeons can execute their surgery plan while in the operating room utilising a patient&rsquo;s CT/MRI scans, allowing enhanced accuracy and efficiency. It provides the ability to rotate the image or make it semi-transparent in order to see behind arteries and other critical structures, something not possible until now, affording for accuracy to be sustained during complex procedures. Also, SNAP&rsquo;s augmented reality and simulation capabilities allow surgeons to analyse virtual &ldquo;what if&rdquo; scenarios before making the actual incision. This precision enables surgeons to gain clinical insight that was previously unavailable.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We have used the SNAP in the operating room in a handful of surgeries. The SNAP&rsquo;s realistic 3D imaging is one-of-a-kind and has been introduced as an integrated operating room device for the first time at our medical centre,&rdquo; says Warren R Selman, chairman, Department of Neurological Surgery, University Hospitals Case Medical Centre, USA.&nbsp; &ldquo;It is just like watching a football game when multiple cameras are located around the arena and an editor can freeze the image, rotate, zoom in, zoom out and see things that he could not otherwise see. In my recent surgeries, I was able to pause the navigation scene during the surgery to rotate the image and to verify that I removed the entire tumour and to make sure that I was within a safe distance from a vital artery while removing the tumour. With the SNAP connected to the operating room navigation platform, the operating room team coordination is enhanced, and we are utilising the best imaging technology tool to benefit our patients.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Surgical Theater&rsquo;s first product, the Surgical Rehearsal Platform (SRP), paved the way to the operating room by providing surgeons with a way to plan and rehearse their surgeries outside of the operating room. To-date it is estimated that the SRP has been utilised by surgeons wanting to pre-live their procedure more than 500 times. Now the SNAP will be utilised to take the pre-planned pathway into the operating room to be used during the surgical procedure thanks to its ability to integrate into operating room navigation equipment. In addition, the flight simulator technology used in the software permits remote connection of multiple platforms; participants anywhere in the world can simultaneously work together and practice the same case with real-time feedback and collaboration.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We are extremely excited to expand our offerings beyond planning and rehearsing surgeries outside the operating room,&rdquo; says Moty Avisar, Surgical Theater chief executive officer and co-founder. &ldquo;The SNAP, our advanced imaging platform, allows us to connect to the operating room navigation system and become a part of the surgery as its performed, enabling a surgeon and operating room team to achieve their goal of delivering the best care and outcome for the patient. We are witnessing strong anticipation from the medical community about this new technology, with multiple pre-orders for the SNAP already placed from hospitals across the country.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Since Surgical Theater obtained FDA clearance on their first product in February 2013, SRPs have been installed in leading research and teaching hospitals across the United States.

The work will begin July 1.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Heart attack and stroke can strike suddenly, and frequently without warning. The best way to reduce premature death from cardiovascular diseases and stroke is to prevent the development of the risk factors that lead to these conditions,&rdquo; says American Heart Association president Elliott Antman, professor of medicine at Harvard Medical School and a senior physician in the Cardiovascular Division of the Brigham and Women&rsquo;s Hospital in Boston. &ldquo;Scientists working in these research centres are seeking to discover mechanisms that will allow all Americans to live healthier lives, and help lead us to a culture of health.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">A culture of health is an environment where the default choices people make are the healthy ones. For example, the air is smoke-free, nutritious foods are easy to find, safe places to exercise are abundant and quality healthcare is accessible.</span></p> <p><span style="font-size: 10pt;"><br />The culture of health concept is also important to the association&rsquo;s goal to improve the cardiovascular health of all Americans by 20% while reducing deaths from cardiovascular diseases and stroke by 20% by 2020.</span></p> <p><span style="font-size: 10pt;">Getting America healthier means making headway in important areas like smoking, physical activity, diet, blood pressure, cholesterol and blood sugar. Northwestern Universitywill take a closer look at why heart-health measures decline from childhood to middle age and see if the latest techniques can help maintain ideal heart health and reverse declines. The goal is to learn how to implement behaviour change programmes on a large scale to benefit the most people.</span></p> <p><br /><span style="font-size: 10pt;">Two major hurdles &ndash; an overly salty, heart-hurting diet and the frequent need to take multiple, expensive medications &ndash; is spurring Vanderbilt University to develop new approaches for preventing high blood pressure. The goals are to understand how salt causes tissue injury, develop a method to detect and lower excess salt, and determine if a simple treatment in one pill can improve cardiovascular health.</span></p> <p><br /><span style="font-size: 10pt;">Nearly one-third of adults and children in the United States are obese, with rates even higher in Hispanic and African-American communities. The Icahn School of Medicine at Mount Sinai will aim to build a culture of health in Harlem, New York, USA with an urban-based health programme. Obesity is closely linked to heart disease, stroke, type 2 diabetes and certain types of cancer, among the leading causes of preventable death.</span></p> <p><br /><span style="font-size: 10pt;">Heart failure, when the heart cannot pump enough blood to the organs, is one of the most common reasons people 65 and older go into the hospital. Since there are no proven therapies to prevent heart failure with preserved ejection fraction, which affects about half of these patients, the University of Texas-Southwestern Medical School wants to shift the focus to prevention. The centre expects to find new interventions that can help heart failure patients in clinical settings.</span></p> <p><br /><span style="font-size: 10pt;">Each network centre will receive about US$3.8 million over the next four years.</span></p></div> China to build &apos;brain database&apos; http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/china-to-build-brain-database 2014-07-01T10:47:00Z 2014-07-01T10:47:00Z <div id="Introduction42" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Chinese scientists are planning to build a &ldquo;brain database&rdquo; in a bid to identify clues to tackling cerebral diseases and related disorders.</strong></span></p> </div><div id="Text142" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;The creation of a unified general and patient database will help us to identify the biomarkers of brain diseases, which we can then use as the basis for early diagnosis and treatment,&rdquo; says Poo Mu-ming, director of the Institute of Neuroscience under the Chinese Academy of Sciences.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;It will also be a useful resource for scientists around the world who are involved in brain research,&rdquo; he adds.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Though few details of the project have been made public, Poo says one of its primary goals will be to find treatments for conditions such as autism and Alzheimer&rsquo;s disease. Autism is a neurodevelopmental disorder whose incidence is on the rise globally. According to official figures, about one million Chinese children are affected by the condition. The World Health Organisation, however, said in 2008 that the country had 7.8 million autistic children. Meanwhile, 50% of the global population aged over 85 has Alzheimer&rsquo;s disease.

This innovation comes from a partnership between The Ohio State University Wexner Medical Center and Battelle.</span></strong></p> </div><div id="Text146" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Ian Burkhart, a 23-year-old quadriplegic from Dublin, USA, is the first patient to use Neurobridge, an electronic neural bypass. Burkhart is the first of a potential five participants in a clinical study.</span><br /><br /><span style="font-size: 10pt;">&ldquo;It is much like a heart bypass, but instead of bypassing blood, we are bypassing electrical signals,&rdquo; said Chad Bouton, research leader at Battelle. &ldquo;We are taking those signals from the brain, going around the injury and going directly to the muscles.&rdquo;</span><br /><br /><span style="font-size: 10pt;">The Neurobridge technology combines algorithms that learn and decode the user&rsquo;s brain activity and a high-definition muscle stimulation sleeve that translates neural impulses from the brain and transmits new signals to the paralysed limb. In this case, Burkhart&rsquo;s brain signals bypass his injured spinal cord and move his hand.</span><br /><br /><span style="font-size: 10pt;">The project investigating the Neurobridge was a six-month, Food and Drug Administration (FDA)-approved clinical trial at Ohio State&rsquo;s Wexner Medical Center.</span><br /><br /><span style="font-size: 10pt;">Working on the internally-funded project for nearly a decade to develop the algorithms, software and stimulation sleeve, Battelle scientists first recorded neural impulses from an electrode array implanted in a paralysed person&rsquo;s brain. They used the data to illustrate the device&rsquo;s effect on the patient and prove the concept.</span><br /><br /><span style="font-size: 10pt;">Two years ago, Bouton and his team began collaborating with Ohio State neuroscience researchers and clinicians Ali Rezai and Jerry Mysiw to design the clinical trials and validate the feasibility of using the Neurobridge technology in patients.</span><br /><br /><span style="font-size: 10pt;">During a three-hour surgery on 22 April, Rezai implanted a chip onto the motor cortex of Burkhart&rsquo;s brain. The tiny chip interprets brain signals and sends them to a computer, which recodes and sends them to the high-definition electrode stimulation sleeve that stimulates the proper muscles to execute his desired movements. Within a tenth of a second, Burkhart&rsquo;s thoughts are translated into action.</span></p></div><div id="Text246" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;The surgery required the precise implantation of the micro-chip sensor in the area of Burkhart&rsquo;s brain that controls his arm and hand movements,&rdquo; Rezai says.</span><br /><br /><span style="font-size: 10pt;">He said this technology may one day help patients affected by various brain and spinal cord injuries such as strokes and traumatic brain injury.</span></p> <p><span style="font-size: 10pt;">Battelle also developed a non-invasive neurostimulation technology in the form of a wearable sleeve that allows for precise activation of small muscle segments in the arm to enable individual finger movement, along with software that forms a &lsquo;virtual spinal cord&rsquo; to allow for coordination of dynamic hand and wrist movements.</span><br /><br /><span style="font-size: 10pt;">The Ohio State and Battelle teams worked together to investigate the correct sequence of electrodes to stimulate and allow Burkhart to move his fingers and hand functionally. For example, Burkhart uses different brain signals and muscles to rotate his hand, make a fist or pinch his fingers together to grasp an object, Mysiw explains. As part of the study, Burkhart worked for months using the electrode sleeve to stimulate his forearm to rebuild his atrophied muscles so they would be more responsive to the electric stimulation.</span><br /><br /><span style="font-size: 10pt;">&ldquo;I have been doing rehabilitation for many years, and this is a tremendous stride forward in what we can offer these people,&rdquo; said Mysiw, chair of the Department of Physical Medicine and Rehabilitation at Ohio State. &ldquo;Now we are examining human-machine interfaces and interactions, and how that type of technology can help.&rdquo; &nbsp;</span></p></div> Covidien announces European launch of Pipeline Flex embolisation device http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/covidien-announces-european-launch-of-pipeline-flex-embolisation-device 2014-06-27T14:14:00Z 2014-06-27T14:14:00Z <div id="ImageMain47" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/covidien-announces-european-launch-of-pipeline-flex-embolisation-device"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/039/pipeline_flex_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction47" style="clear:both;"> <p><strong><span style="font-size: 11pt;">Covidien announced the European launch of its Pipeline Flex embolisation device at the annual Live Interventional Neuroradiology and Neurosurgery Course (LINNC, 23&ndash;25 June, Paris, France).

The 59 adult migraine patients who were enrolled in the study had to have had more than 15 headache days per month in the three months preceding the trial, in accordance with the ICHD definition of Chronic Migraine.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />During the comparative period, the patients were randomised and given either an active gammaCore device or a sham device that appeared identical but did not stimulate the vagus nerve. Neither the patient, nor the physician, nor the clinical trial monitors were aware of which device each patient was given. The patients self-administered the treatment by placing the gammaCore device on the right sides of their necks, over their vagus nerves, three times daily. Each treatment consisted of two 90-second stimulations, five to ten minutes apart.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />In the two month comparative phase, there was a decrease of 1.9 headache days per 28 days with three nVNS treated patients having more than a 50% decrease, and one having a 75% decrease in headache days. No sham control patients achieved a significant reduction. During the open label phase, the drop in headache days continued to grow, with patients originally randomised to the active therapy and remaining on therapy through the full six-month open label phase, experiencing more than an eight day drop in headache days per month. Among the entire group of patients remaining on therapy for the defined six months, 38% experienced a 50% reduction in headache days per month.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />JP Errico founder and chief executive officer of electroCore comments, &ldquo;We continue to be pleased by the clinical studies that consistently demonstrate nVNS therapy to be a safe, easy to use, preventative treatment that reduces the burden of severe headache for many patients. Although only a pilot study, these results confirms our intention to continue with larger scale studies in the prevention of migraine. We look forward to the full presentation of this data, and are continuing to explore the efficacy of nVNS in a range of related diseases and disorders.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Data from all the 59 patients are included in the safety study.

PPMI will enrol 250 people with the LRRK2 mutation and Parkinson&rsquo;s and 250 people with the mutation but without Parkinson&rsquo;s. Since the SNCA mutation is rarer, the study is recruiting 50 people with Parkinson&rsquo;s and the mutation and 50 people with the SNCA mutation but without Parkinson&rsquo;s disease. These participants will be followed for five years.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Launched in 2010, PPMI is a longitudinal clinical study that collects standardized clinical, imaging and biologic data.

Philips&rsquo; new interventional X-ray solution offers more effective device guidance and placement in every neuroradiology procedure.</strong></span></p> </div><div id="Text154" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The first NeuroSuite system was recently installed at Karolinska University Hospital, Stockholm, Sweden. This hospital is one of the world&acute;s leading medical universities and a centre of excellence for stroke treatment.</span></p> <p><span style="font-size: 10pt;"><br />Neuroradiology is a branch of radiology that involves the diagnosis and minimally invasive treatment of the brain, head, neck and spine. These treatments require the insertion of a catheter, which must be navigated through a very narrow (with vessels less than 2mm wide) and tortuous vasculature to the treatment site with the aid of live image guidance. New devices (eg. stents and flow diverters) offer new treatments for ischaemic stroke or large neck aneurism, but their increasingly smaller designs make the devices more difficult to see with X-ray imaging. This can present additional challenges for placement and treatment assessment.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />To cope with these challenges Philips&rsquo; NeuroSuite consists of a bi-plane interventional X-ray system with a unique combination of two new detectors: Philips&rsquo; frontal FD20 detector delivers live 2D and 3D imaging to provide live navigation and immediate therapy feedback. The smaller, lateral FD15 detector can be positioned beyond the shoulders and very close to the head. This shorter distance and unique combination of detectors provides sharp, full brain imaging at lower X-ray dose and 3D imaging optimised for neuro and spine interventions.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;In image-guided interventions the ultimate goal is to see clearly and navigate effectively, while managing X-ray dose for patients, staff and clinicians,&rdquo; says Ronald Tabaksblat, general manager Interventional X-ray at Philips Healthcare. &ldquo;Developed in collaboration with clinical partners around the world, Philips NeuroSuite has been designed for that purpose and underpins Philips&rsquo; global leadership position in live-image guidance technologies.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br /><br />&ldquo;In interventional neuroradiology the performance of the angiographic system is crucial to patient safety,&rdquo; says Michael S&ouml;derman, associate professor and chief of Neuroangiography and Stereotaxy, Department of Neuroradiology, Karolinska University Hospital. &ldquo;Philips&rsquo; latest innovation is NeuroSuite with a new 20 inch detector on the frontal plane, providing superb 3D-images and big enough for spine imaging. On the lateral plane, the new 15 inch detector brings visualization of the complete cerebral vasculature, with reduced collision risks and enhanced projection freedom.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />At the heart of NeuroSuite is Philips AlluraClarity, lowering radiation dose by as much as 73% without compromising image quality: and VasoCT that visualises intracranial devices in vessel context and vessel morphology down to perforator vessels.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Over the last years a lot of progress was made on high resolution device visualisation,&rdquo; says Jacques Moret of the faculty of medicine Bichat-Beaujon at the University of Paris, France. &ldquo;The next step in our collaboration with Philips is the NeuroSuite bringing enhanced vessel and device visualisation and full head coverage.

Led by&nbsp;Elizabeth M C Hillman, associate professor of biomedical engineering, the team has demonstrated for the first time that the vascular endothelium plays a critical role in the regulation of blood flow in response to stimulation in the living brain.</strong></span></p> </div><div id="Text161" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;We think we have found a missing link in our understanding of how the brain dynamically tunes its blood flow to stay in sync with the activity of neurons,&rdquo; says Hillman, who has a joint appointment in Radiology. &ldquo;Earlier studies identified small pieces of the puzzle, but we did not believe they formed a cohesive &lsquo;big picture&rsquo; that unified everybody&rsquo;s observations. Our new finding seems to really connect the dots.&rdquo;</span><br /><br /><span style="font-size: 10pt;">Understanding how and why the brain regulates its blood flow could provide important clues to understanding early brain development, disease, and ageing. The brain increases local blood flow when neurons fire, and this increase is what is detected by a functional magnetic resonance imaging (fMRI) scan. Hillman found that the vascular endothelium, the inner layer of blood vessels, plays a critical role in propagating and shaping the blood flow response to local neuronal activity. While the vascular endothelium is known to do this in other areas of the body, until now the brain was thought to use a different, more specialised mechanism and researchers in the field were focused on the cells surrounding the vessels in the brain.</span><br /><br /><span style="font-size: 10pt;">&ldquo;Once we realised the importance of endothelial signalling in the regulation of blood flow in the brain,&rdquo; Hillman adds, &ldquo;we wondered whether overlooking the vascular endothelium might have led researchers to misinterpret their results.&rdquo;</span><br /><br /><span style="font-size: 10pt;">&ldquo;We really hope that our work will encourage others to take a closer look at the vascular endothelium in the brain. So far, we think that our findings have far-reaching and really exciting implications for neuroscience, neurology, cardiovascular medicine, radiology, and our overall understanding of how the brain works,"&nbsp;she continues.</span><br /><br /><span style="font-size: 10pt;">The research was carried out in Hillman&rsquo;s&nbsp;Laboratory for Functional Optical Imaging, led by PhD student and lead author on the study, Brenda Chen. Other lab members who assisted with the study included PhD and MD/PhD students from Columbia Engineering, Neurobiology and Behavior, and Columbia University Medical Center.&nbsp;</span><br /><br /><span style="font-size: 10pt;">To tease apart the role of endothelial signalling in the living brain, they had to develop new ways to both image the brain at very high speeds, and also to selectively alter the ability of endothelial cells to propagate signals within intact vessels. The team achieved this through a range of techniques that use light and optics, including imaging using a high-speed camera with synchronised, strobe LED illumination to capture changes in the colour, and thus the oxygenation level of flowing blood. Focused laser light was used in combination with a fluorescent dye within the bloodstream to cause oxidative damage to the inner endothelial layer of blood brain arterioles, while leaving the rest of the vessel intact and responsive. The team showed that, after damaging a small section of a vessel using their laser, the vessel no longer dilated beyond the damaged point. When the endothelium of a larger number of vessels was targeted in the same way, the overall blood flow response of the brain to stimulation was significantly decreased.</span><br /><br /><span style="font-size: 10pt;">&ldquo;Our finding unifies what is known about blood flow regulation in the rest of the body with how it is regulated in the brain,&rdquo; Hillman explains. &ldquo;This has wider reaching implications since there are many disease states known to affect blood flow regulation in the rest of the body that, until now, were not expected to directly affect brain health.&rdquo; For instance, involvement of the endothelium might explain neural deficits in diabetics; a clue that could lead to new diagnostics tests and treatments for neurological conditions associated with broader cardiovascular problems."</span><br /><br /><span style="font-size: 10pt;">&ldquo;Improving our fundamental understanding of how and why the brain regulates its blood flow is key to understanding how and when this mechanism could be altered or broken,&rdquo; she says. &ldquo;We think this could extend to studies of early brain development, ageing, and diseases such as Alzheimer&rsquo;s and dementia.&rdquo;</span><br /><br /><span style="font-size: 10pt;">The team&rsquo;s research findings may also explain the effects of some drugs on the brain, and on the fMRI response to stimulation, since the vascular endothelium is exposed to chemicals in the bloodstream. &ldquo;Overall, this work could dramatically improve our ability to interpret fMRI data collected in humans, perhaps making it a better tool for doctors to understand brain disease,&rdquo; she adds.</span><br /><br /><span style="font-size: 10pt;">Hillman plans next to address the broad range of implications her latest finding may have. She wants to explore the effects of drugs and disease states on the coupling of blood flow to neuronal activity in the brain, and is now starting studies to explore fMRI data from a range of different disease states to see whether she can find signs of neurovascular dysfunction. She is also working on characterising the co-evolution of neuronal and haemodynamic activity during brain development and is beginning to develop new imaging tools that will enable non-invasive, inexpensive monitoring of brain haemodynamics in infants and children who cannot be imaged within an MRI scanner.</span><br /><br /><span style="font-size: 10pt;">This research is supported by the National Institutes of Health (through the National Institute of Neurological Disorders and Stroke) as well as the National Science Foundation, the Human Frontier Science Programme and the Rodriguez family.</span></p></div> Foreign body retrieval could be new indication for Trevo ProVue in the cerebrovascular system http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/foreign-body-retrieval-could-be-new-indication-for-trevo-provue-in-the-cerebrovascular-system 2014-06-17T11:44:00Z 2014-06-17T11:44:00Z <div id="ImageMain62" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/foreign-body-retrieval-could-be-new-indication-for-trevo-provue-in-the-cerebrovascular-system"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/039/Enterprise_coil_retrieval_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction62" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>A case report has described the novel use of a stent for the removal of a foreign body from the cerebrovascular system.</strong></span></p> </div><div id="Text162" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">According to the authors, Mouhammed R Kabbani <em>et al</em>, the case was a man with a large left cavernous internal carotid artery cerebral aneurysm.

The most widely used treatment is the drug levodopa, although after prolonged use patients can develop involuntary muscle spasms (dyskinesias) and motor fluctuations. There is less risk of developing these complications with dopamine agonists or with monoamine oxidase type B inhibitors than with levodopa, but other side effects including nausea, hallucinations, oedema, and sleep disturbance are increased with these newer drugs.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Previous studies included too few patients, had short follow-up, and focused on the clinicians&rsquo; assessments of motor symptoms rather than asking patients how the drugs affected their overall quality of life.

With up to seven years of follow-up, self-reported scores on scales measuring mobility and quality of life showed small but persistent benefits of starting treatment with levodopa rather than the other drugs. Patients in the levodopa group also reported significantly better scores on the activities of daily living, stigma, cognition, communication, and bodily discomfort scales than those taking levodopa-sparing therapy despite more involuntary muscle spasms.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />According to Gray, &ldquo;Although the differences in favour of levodopa are small, when you consider the short- and long-term benefits, side-effects, quality of life for patients, and costs, the old drug levodopa is still the best initial treatment strategy for most patients.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />He adds, &ldquo;In current clinical practice, most patients younger than 70 years are treated initially with a dopamine agonists to avoid levodopa-related motor complications.

The patients, median age 24 years, had &ldquo;intractable&rdquo; seizures despite treatment with antiepileptic drugs.</span></p> <p><br /><span style="font-size: 10pt;"> In the SLAH procedure, a saline-cooled fiberoptic laser probe was precisely targeted to the area of the brain&mdash;the &ldquo;amygdalohippocampal complex&rdquo;&mdash;responsible for the procedures. Using real-time MRI guidance, the neurosurgeon was able to pinpoint the area of the brain responsible for seizure activity and destroy (ablate) by computer-controlled laser energy, without harming neighbouring brain tissue.</span></p> <p><br /><span style="font-size: 10pt;"> The technical aspects of the procedure were successfully carried out in all patients. Using thermal imaging and MRI guidance, the surgeons were able to see the area of laser ablation as treatment proceeded. The average laser exposure time was just under 10 minutes.</span></p> <p><br /><span style="font-size: 10pt;"> On average, 60% of the amygdalohippocampal complex was destroyed in the SLAH procedure; the average length of the ablated area was 2.5 centimetres. Median time spent in the hospital was just one day&mdash;compared to a typical two to five-day stay after conventional temporal lobe surgery, and SLAH patients did not have to be admitted to the intensive care unit.</span></p> <p><br /><span style="font-size: 10pt;"> Most important, the procedure was effective in reducing or eliminating seizures in patients with MTLE. At a median of 14 months after SLAH, 10 out of 13 patients achieved meaningful seizure reductions, while seven were free of &ldquo;disabling seizures.&rdquo; This included six out of nine patients whose epilepsy was caused by an abnormality called mesial temporal sclerosis.</span></p> <p><br /><span style="font-size: 10pt;"> Although some complications occurred, none were directly caused by laser application. Two patients had an additional SLAH procedure to control seizures, and another patient underwent standard open surgery.</span><br /> <br /> <br /><span style="font-size: 10pt;"> Open brain surgery is the standard treatment for patients with intractable MTLE. Surgery has a high success rate, but carries a significant risk of neurological and cognitive (intellectual) impairment. Minimally invasive approaches like the new MRI-guided laser ablation technique might produce similar seizure control with lower risks than surgery.</span></p> <p><br /><span style="font-size: 10pt;"> The new study shows &ldquo;technical feasibility and encouraging results&rdquo; with the minimally invasive MRI-guided SLAH technique for patients with MTLE. Effectiveness in relieving or eliminating seizures approaches that of surgery&mdash;perhaps especially among patients whose seizures are caused by mesial temporal sclerosis. &ldquo;These are promising results considering that this reflects our initial experience, and results may improve with greater experience with this novel technique,&rdquo; notes Gross.</span></p> <p><br /><span style="font-size: 10pt;"> &ldquo;Such minimally invasive techniques may be more desirable to patients and result in increased use of epilepsy surgery among the large number of medically intractable epilepsy patients,&rdquo; Gross and colleagues conclude. They note that a larger, longer-term study of SLAH is underway, including assessment of the effects on cognitive function as well as seizures.</span></p></div> Clinical trial tests possible benefits of brain stimulation on hand and arm movement following stroke http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/clinical-trial-tests-possible-benefits-of-brain-stimulation-on-hand-and-arm-movement-following-stroke 2014-06-05T17:47:00Z 2014-06-05T17:47:00Z <div id="ImageMain76" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/clinical-trial-tests-possible-benefits-of-brain-stimulation-on-hand-and-arm-movement-following-stroke"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/039/Nexstim_stroke_therapy_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction76" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Researchers at Shepherd Center, Atlanta, USA, are studying whether stimulating the brain before rehabilitation could yield greater gains in motor function for people recovering from stroke. Researchers believe that the new approach could change common practices of care for certain stroke patients.</strong></span></p> </div><div id="Text176" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Shepherd Center is one of 12 US centres participating in a clinical trial that is evaluating whether coupling navigated transcranial magnetic stimulation (TMS) of the brain with standard occupational therapy can measurably improve hand and arm function following a stroke. Experts say this approach could unlock a totally new, non-invasive treatment to promote recovery and function.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;It&rsquo;s really a seminal study in neurorehabilitation that, if successful, will change common practices for how we take care of certain stroke patients,&rdquo; says Ford Vox, a physical medicine and rehabilitation physician at Shepherd Center and primary investigator for this study. &ldquo;We have this golden opportunity right after someone has a stroke when we know people are most likely to improve or recover function, and this therapy may offer patients the best potential.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Shepherd Center is testing a navigated brain stimulation system developed by a Finnish medical technology company called Nexstim. It uses transcranial magnetic stimulation therapy to apply a mild electromagnetic current to excite the brain, a technique that can be used to both investigate the brain&rsquo;s functions and change them. The technique is growing in popularity as a way to map the brain before surgery and as a treatment for depression. Nexstim&rsquo;s device provides visual guidance to the operator, who uploads and correlates MRI pictures of the patient&rsquo;s brain with the device&rsquo;s infrared guidance system. Then, the device creates a 3-D model of the patient&rsquo;s brain, pinpointing the target site for stimulation in real time (called stereotactic guidance).</span></p> <p><br /><span style="font-size: 10pt;">In this new trial, clinicians believe transcranial magnetic stimulation works by slowing activity in the healthy area of the brain, which can become overly active following a stroke, causing detriment to the injured side.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;By reducing brain activity on the side of the brain that was not injured, the injured side may actually have a better chance of recovery,&rdquo; Vox explains.</span></p> <p><br /><span style="font-size: 10pt;">The technology is akin to a more advanced version of constraint-induced therapy in which clinicians physically tie down a patient&rsquo;s good arm, which forces the patient to use the injured side. With Nexstim&rsquo;s non-invasive device, researchers are using electromagnetism to slow activity in portions of the healthy brain hemisphere that control the uninjured arm, similarly forcing the brain to use its injured half.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;People who have experienced a stroke often have limited resources and rehabilitation benefits,&rdquo; Vox notes. &ldquo;If initial results are confirmed, patients might be able to get that much more out of the limited time they have with therapists by using this technology.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Eligible clinical trial participants receive either the navigated brain stimulation or a sham (simulated) treatment in conjunction with six weeks of hand and arm therapy provided by an occupational therapist. Researchers and study participants do not know whether they are in the treatment or simulation group. Visits start with 20 minutes of standardised, task-oriented activity followed by the treatment or simulated therapy and then an hour of upper-limb rehabilitation therapy.</span></p> <p><br /><span style="font-size: 10pt;">The goal is to improve a patient&rsquo;s range of motion, coordination, flexibility, strength, and use of the weak arm and hand. Specifically, researchers are interested to see whether &ndash; at the end of the study &ndash; patients are better able to perform daily activities, such as dressing, grooming, cooking, doing laundry, writing, typing and leisure activities. For example, is a patient now able to button a shirt that he couldn&rsquo;t before, open a jar or screw-top bottle, pour beverages, manipulate keys to lock and unlock doors, use a phone or fold laundry?</span></p> <p><br /><span style="font-size: 10pt;">In a similarly designed pilot study of the device conducted at the Rehabilitation Institute of Chicago, researchers found striking improvements in motor function among people receiving the targeted stimulation compared with those in the simulation group. At six months post-stroke, these patients were 30% more likely to have meaningful arm recovery (80% compared with just 50%). Researchers presented their findings in February 2014 at the American Heart Association and the American Stroke Association&rsquo;s International Stroke Conference.</span></p></div> Mayo Clinic moves small-molecule drugs through blood-brain barrier http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/mayo-clinic-moves-small-molecule-drugs-through-blood-brain-barrier 2014-06-05T17:06:00Z 2014-06-05T17:06:00Z <div id="Introduction77" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Researchers at Mayo Clinic have demonstrated in a mouse model that their recently developed synthetic peptide carrier is a potential delivery vehicle for brain cancer chemotherapy drugs and other neurological medications. The findings appear in <a href="http://www.plosone.org/" target="_blank"><em>PLOS ONE</em></a>.</strong></span></p> </div><div id="Text177" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;Not only have we shown that we can transport eight different molecules, we think this method will be less disruptive or invasive because it mimics a normal physiological process,&rdquo; says Mayo Clinic neuroscientist Gobinda Sarkar, the corresponding author of the study. The researchers are able to transport the drugs without modifying any of the molecules involved. They say this development will aid in evaluation of potential new drugs for brain cancer.</span></p> <p><br /><span style="font-size: 10pt;">The blood-brain barrier is meant to protect the brain from numerous undesirable chemicals circulating in the body, but it also obstructs access for treatment of brain tumours and other conditions. Too often the only recourse is invasive, which often limits a drug&rsquo;s effectiveness or causes irreversible damage to an already damaged brain. Nearly all of the drugs that could potentially help are too large to normally pass through the barrier. Additionally, other methods may damage the vascular system.</span></p> <p><br /><span style="font-size: 10pt;">In this case, the synthetic peptide K16ApoE, once injected into a vein, binds to proteins in the blood to create entities that can pass for near-normal ligands to some receptors present on the blood-brain barrier. The &lsquo;pseudo-ligand&rsquo; receptor interaction creates what the researchers believe to be transient pores through which various molecules can be transported to the brain. The molecules they&rsquo;ve transported in this manner include cisplatin, methotrexate, cetuximab, three different dyes, and synthetic peptides Y8 and I-125. The researchers believe this is the least complicated, least expensive and most versatile method for delivering therapeutics to the brain. Previously, the researchers delivered antibodies targeted against amyloid plaques into the brains of mouse models of Alzheimer&rsquo;s disease using this same method.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;We know that some chemotherapeutic agents can kill brain tumour cells when they are outside the brain (as in a laboratory test). But because the agents cannot cross the blood-brain barrier, they are not able to kill brain tumour cells inside the brain. With the peptide carrier, these agents can now get into the brain and potentially kill the tumour cells,&rdquo; says Mayo neurology researcher Robert Jenkins, senior author of the study.</span></p> <p><br /><span style="font-size: 10pt;">The researchers say their method, which has been successfully demonstrated in mice, meets three of five requirements for a usable therapy: It&rsquo;s feasible as a repeated procedure; it should be relatively easy to introduce into medical practice; and it would work for any size or location of brain tumour. More research will need to be done to prove effectiveness and determine any adverse effects.</span></p> <p><br /><span style="font-size: 10pt;">The research was supported by Mayo Clinic, Bernie and Edith Waterman, and the Ting Tsung and Wei Fong Chao Family Foundation.

The results show an impressive therapeutic effect of AD04 and make it the first ever compound demonstrating clinical and biomarker evidence consistent with disease modification of Alzheimer&rsquo;s disease. A statistically significant correlation was demonstrated between the cognitive/functional outcome and the volume of the hippocampus, the region of the brain locating the cognitive/memory functions, both of which demonstrated positive impact on disease progression over 18 months. Similar stabilisation was also seen across behavioural and quality of life outcomes.</span></strong></span></p> </div><div id="Text179" style="clear:both; text-align:left"><p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt; font-family: Helvetica, sans-serif; color: #333333;">There was also a stabilisation of the cognitive/functional endpoint found in those patients of this study who were treated with AD02, so far the company&rsquo;s lead compound in AD. Dependent on dosage and formulation of AD02 in three different study arms, 24-31% of the patients showed cognitive/functional stabilisation or improvement. However, statistically significant correlation with biomarker Hippocampus volume could not be demonstrated within the observation period of 18 months. Altogether 332 patients were treated in an international multicentric clinical trial into five different study arms, and over 85% completed the study.</span></p> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt;"><strong><span style="font-family: Helvetica, sans-serif; color: #333333;">Significant Impact</span></strong><span style="font-family: Helvetica, sans-serif; color: #333333;">&nbsp;</span></span></p> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt; font-family: Helvetica, sans-serif; color: #333333;">Commenting on these results, <span class="xn-person">Walter Schmidt</span>, chief executive officer and co-founder of AFFiRiS AG, states: &ldquo;Our results demonstrate that AD04 is the first drug ever to show disease modifying properties in Alzheimer&rsquo;s patients. This success is owed to our strategy of clinical maturation, which in the case of Alzheimer&rsquo;s has so far moved forward four different product candidates namely AD01 - AD04 into clinical development.&rdquo;</span></p> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt;"><span class="xn-person"><span style="font-family: Helvetica, sans-serif; color: #333333;">Frank Mattner</span></span><span style="font-family: Helvetica, sans-serif; color: #333333;">, chief scientific officer and co-founder, adds: &ldquo;Both compounds applied in this trial, AD02 and AD04, showed excellent safety profiles. Top compound AD02 performed very well in stabilisation of cognitive functions in a dose dependent manner. 24-31 % of treated patients showed stabilisation of clinical progression. However, AD04 turned out to be superior to AD02 as 47% of the patients stabilised regarding their cognitive/functional status. On top of this, this effect was statistically significantly correlated with the rescue of the hippocampus, the region of the human brain, where cognitive and memory functions are located (p=0.0016). This correlation of significant clinical and biomarker effects meets EMA&rsquo;s and FDA&rsquo;s definition of disease modification in the context of a compound with a consistent mode of action. Therefore, we decided to have a strong focus on AD04 for further clinical development. Our strategy of clinical maturation allows for an efficient progress during clinical development. By doing so, it reduces financial risks associated with any clinical trial.&rdquo; In fact, the clinical maturation strategy has been established by AFFiRiS and is based on parallel clinical testing of several drug candidates against a certain disease to ensure that the best therapy for humans will be developed.&rdquo;</span></span></p></div> A new approach to Alzheimer&apos;s disease research http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/a-new-approach-to-alzheimers-disease-research 2014-06-05T12:12:00Z 2014-06-05T12:12:00Z <div id="Introduction80" style="clear:both;"> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 11pt;"><strong><span style="font-family: Helvetica, sans-serif; color: #333333;">As part of its ongoing research to better understand the complexities of the human brain, the Allen Institute for Brain Science, Seattle, USA, is embarking on the first effort to map connectivity patterns across the whole brain in mouse models of Alzheimer&rsquo;s disease, through its recent award of a<span class="apple-converted-space">&nbsp;US</span><span class="xn-money">$3.4 million</span><span class="apple-converted-space">&nbsp;</span>grant over five years from the National Institute on Aging of the National Institutes of Health.&nbsp;</span></strong></span></p> </div><div id="Text180" style="clear:both; text-align:left"><p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt; font-family: Helvetica, sans-serif; color: #333333;">&ldquo;Many studies on Alzheimer&rsquo;s disease focus on just one or a small number of areas in the brain, such as the hippocampus, for its role in memory,&rdquo; says<span class="apple-converted-space">&nbsp;</span><span class="xn-person">Julie Harris</span>, assistant investigator at the Allen Institute for Brain Science and primary investigator on the grant. &ldquo;By studying connections across the entire cortex in both normal mice and mouse models of the disease, we hope to finally make the breakthroughs that will help us understand the pathways through which Alzheimer&rsquo;s disease spreads, and what interventions we can make against its progression.&rdquo;</span></p> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt; font-family: Helvetica, sans-serif; color: #333333;">So far, clinical trials for drugs developed in mouse models that typically focus on individual brain areas have yielded poor results. &ldquo;Our expanded view of the disease that looks at connections across the whole brain will hopefully improve mouse models and their use in translational research to identify drugs and treatments that work in humans,&rdquo; says Harris.</span></p> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt; font-family: Helvetica, sans-serif; color: #333333;">The whole-brain model of Alzheimer&rsquo;s builds on the Allen Mouse Brain Connectivity Atlas, recently profiled in the journal<span class="apple-converted-space">&nbsp;</span><em>Nature</em>, which allows researchers to quantitatively analyse connections across the entire mouse brain.</span></p> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 10pt; font-family: Helvetica, sans-serif; color: #333333;">Harris and her colleagues plan to expand the resource by focusing on areas of the brain that are hardest hit early in the disease.

Silent brain infarction is a brain injury likely caused by a blood clot interrupting blood flow to brain tissue. Sometimes called &ldquo;silent strokes,&rdquo; these injuries are symptomless and are a risk factor&nbsp;for future strokes.</span></p> <p><br /><span style="font-size: 10pt;">Previous studies indicated migraine could be an important stroke risk factor for younger people.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;I do not believe migraine sufferers should worry, as the risk of&nbsp;ischemic stroke&nbsp;in people with migraine is considered small,&rdquo; says Teshamae Monteith, lead author of the study and assistant professor of clinical neurology and chief of the Headache Division at the University of Miami Miller School of Medicine, USA. &ldquo;However, those with migraine and vascular risk factors may want to pay even greater attention to lifestyle changes that can reduce stroke risk, such as exercising and eating a low-fat diet with plenty of fruits and vegetables.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">High blood pressure, another important stroke risk factor, was more common in those with migraine.

The Space Foundation honour is directed at technologies originally developed for space exploration that are being transformed into products to help improve the quality of life on Earth.</strong></span></p> </div><div id="Text190" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;As an element of the future of neurosurgery, Symbis involves developing more precise minimally-invasive techniques with motion refinement where surgeons can reach small and eloquent areas to remove diseased tissue, and cause no damage to the adjacent delicate structures to protect the patient&rsquo;s quality of life and maximise the success of the surgery,&rdquo; says Meir Dahan, IMRIS chief technology officer and executive vice president of Research and Development.</span></p> <p><br /><span style="font-size: 10pt;">The Symbis programme originated in 2002 under the name neuroArm as a collaborative research concept primarily between the University of Calgary and MacDonald, Dettwiler and Associates (MDA) - the company which developed large robotic arms for the International Space Station and US space shuttle programmes. Design work initially focused on developing haptic (touch sensing) control mechanisms, special motors, semi-automated surgical tool exchange protocols, and communications technologies. The intent was to pair near real-time, high-resolution magnetic resonance (MR) and anatomical images with robotic arm manipulation technologies to provide neurosurgeons with image guidance, precision, accuracy and dexterity.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Where Symbis has come from and is heading to, represents collaborations of many interdisciplinary creative teams of engineers, scientists and surgeons. Our goal was to integrate the surgeon&rsquo;s skills and decision making with mechanised accuracy,&rdquo; says Garnette Sutherland, professor of neurosurgery at University of Calgary, who led the team which developed the original robot, neuroArm. &ldquo;This honour and research illustrates how the merging of human surgical experience with machines and computerised technology is driving neurosurgical advancement towards more minimalism and finer accuracy.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">The Symbis system now consists of two manipulator arms with eight degrees of freedom of movement on a mobile base and a remote workstation where a surgeon sits and is provided with a virtual environment that recreates the sight, sound and touch of surgery. The arms operate surgical tools only in conjunction with the surgeon&rsquo;s remote hand movements. (The Symbis Surgical System is not currently available for sale.)</span></p> <p><br /><span style="font-size: 10pt;">In 2008, the original neuroArm was first used by Sutherland to remove a brain tumour from a patient at Foothills Medical Centre in Calgary and since has been used 60 times for tumour and vascular malformation cases. IMRIS acquired the technology in 2010 to further develop it into an MR-compatible system that will one day allow the surgeon to do surgery using real time MR imaging in the bore of the magnet. IMRIS is currently working towards a commercialised second generation model integrated within the Visius Surgical Theatre with intraoperative MRI or CT.</span></p> <p><br /><span style="font-size: 10pt;">IMRIS chief executive officer and president Jay D Miller says, &ldquo;We are honoured by this award and recognise the pioneering leadership, experience and general support that was brought together to create this game changing tool. By finding ways to improve the vision and precision of surgery through these tools, we are working towards mitigating risks and improving the outcomes for neurosurgical patients and lower costs for the health care system.&rdquo;</span></p> <p><br /><span style="font-size: 10pt;">Space Technology Hall of Fame inductees were recognised during a ceremony on May 22 in Colorado Springs, USA. The Hall of Fame was created in 1988 by the non-profit Space Foundation to increase public awareness of the benefits resulting from space exploration programmes and encourage further innovation. IMRIS, MDA, and the University of Calgary were inducted as organisations; and Sutherland was admitted as an individual.</span></p></div> Significant milestones set in world&apos;s most detailed brain imaging study to help unlock root causes of dementia http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/significant-milestones-set-in-worlds-most-detailed-brain-imaging-study-to-help-unlock-root-causes-of-dementia 2014-05-29T12:47:00Z 2014-05-29T12:47:00Z <div id="ImageMain91" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/significant-milestones-set-in-worlds-most-detailed-brain-imaging-study-to-help-unlock-root-causes-of-dementia"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/038/Siemens_main.jpg" border="0" vspace="5" /></a></div><div id="Introduction91" style="clear:both;"> <p style="line-height: 15.0pt; background: white; margin: 0cm 0cm 7.5pt 0cm;"><span style="font-size: 11pt;"><strong><span style="font-family: Helvetica, sans-serif; color: #333333;">Having enlisted thousands of Britons and captured detailed information about their health and lifestyle, UK Biobank is now turning its attention to their brains<em>&mdash;</em>as part of the global effort to defeat dementia.
