Hopefully, academic or industry researchers can now develop new drugs to inhibit SYK which are suitable for clinical trials in Alzheimer&rsquo;s disease.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">In working out how an anti-hypertensive drug called Nilvadipine works to reduce amyloid protein accumulations, Roskamp researchers realized the drug also had positive effects on neuroinflammation and thetau protein. The scientists retraced the molecular steps leading to these three factors and discovered they all led back to the SYK protein.<br /><br /></span></p> <p><span style="font-size: 10pt;">Paris then went on to show that drugs blocking SYK activity in the brain could represent a new strategy for treating alzheimer&rsquo;s. "The potential for developing a single "multi-modal" drug treatment that will control all three of these alzheimer&rsquo;s characteristics has us very excited,&rdquo; Paris says. &ldquo;All of these pathologies are interrelated. In theory, by interrupting these three molecular pathways, we can develop more effective drugs to stop the disease. To date, all the drugs that have been tested only attack one alzheimer&rsquo;s characteristic, at a time. What is needed is one drug to address all three.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">Having discovered and demonstrated the molecular pathway linking SYK with these traits, Roskamp scientists are looking forward to testing their hypothesis, either by developing new drugs themselves or partnering with academic and commercial groups.<br /><br /></span></p> <p><span style="font-size: 10pt;">&ldquo;We didn&rsquo;t know until now that SYK was a possible therapeutic target for alzheimer&rsquo;s disease,&rdquo; says Fiona Crawford, chief executive officer of the Roskamp Institute. &ldquo;We&rsquo;d be delighted for anyone to come up with an &lsquo;anti-SYK&rsquo; treatment to stop alzheimer&rsquo;s.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">&ldquo;These findings are really significant,&rdquo; states David H Cribbs, research professor at University of California Irvine, associate director of the Institute for Memory Impairment and Neurological Disorders, and co-leader of the University of California Irvine alzheimer&rsquo;s Disease Research Center neuropathology core.<br /><br /></span></p> <p><span style="font-size: 10pt;">&ldquo;With all of the failures of the clinical trials of drugs for this dementia up to this point the finding of new therapeutics is wonderful. And Nilvadipine has a good safety profile,&rdquo; he adds. A phase III clinical trial of Nilvadipine for alzheimer&rsquo;s disease is currently underway in Europe.<br /><br /></span></p> <p><span style="font-size: 10pt;">Five hundred alzheimer&rsquo;s patients in 26 clinics across nine countries are participating in the double-blind, placebo-controlled study that began in 2013. Each participant will be followed for 18 months to see if the drug is effective at slowing or stopping the course of the disease.</span></p></div> Encouraging trial results for electroCore’s non-invasive vagus nerve stimulation treatment for headaches http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/encouraging-trial-results-for-electrocores-non-invasive-vagus-nerve-stimulation-treatment-for-headaches 2014-10-27T15:50:00Z 2014-10-27T15:50:00Z <div id="ImageMain2" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/encouraging-trial-results-for-electrocores-non-invasive-vagus-nerve-stimulation-treatment-for-headaches"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/gammaCore_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction2" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Preliminary results of an open-label trial carried in the <em><a href="http://www.thejournalofheadacheandpain.com/">Journal of Headache and Pain</a></em> reported that a single treatment with electroCore&rsquo;s handheld non-invasive vagus nerve stimulation device gammaCore, completely resolved 44.8% of migraines within 30 minutes, with an additional 11.4% experiencing moderate benefits (incomplete resolution of their headaches) by two hours.&nbsp;</strong></span><br /> <!--[endif]--></p> </div><div id="Text12" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">This result follows two presentations at the International Headache Meeting in Copenhagen in September showing that patients using gammaCore plus standard of care achieved a 43.4% reduction in the number of weekly cluster headache attacks compared with 12.5% (p=0.002) in patients treated with the best available standard of care. It also found that patients experienced a greater reduction in number of attacks the longer they stayed on treatment.<br /><br /></span></p> <p><span style="font-size: 10pt;">This open-label migraine study was carried out at the Headache Centre in the Neurological Institute in Milan. The study involved thirty patients, 18 &ndash; 65, who had migraine without aura and suffered from five to nine attacks per month. Patients treated between three and six migraine episodes with gammaCore. Ninety six migraine attacks were treated by a single dose. Forty three attacks were resolved completely within 30 minutes (44.8%); for 42 (43.7%) attacks the application did not show any benefit in the first two hours so patients recurred to rescue medication; in 11 (11.4%) attacks the result was uncertain: no resolution of attack, only a moderate relief of pain. No adverse events were recorded.<br /><br /></span></p> <p><span style="font-size: 10pt;">Licia Grazzi, lead author, comments: &ldquo;The results look very promising and patients found the therapy easy to apply and it was well tolerated.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">electroCore had previously reported, at the <em><a href="http://www.americanheadachesociety.org/">American Headache Society</a></em> that a US prevention of chronic migraine study, with a sham control arm, met its primary endpoint of safety, and demonstrated a reduction in the number of headache days per month for patients using the active device. The study suggests that patients who remain on therapy for longer periods of time, enjoy progressively larger decreases in headache days.<br /><br /></span></p> <p><span style="font-size: 10pt;">electroCore, which is running the broadest headache trial programs in the world, will report shortly on two further sham-controlled clinical studies; a US trial on the acute treatment of episodic and chronic cluster, and a European trial on the acute treatment of episodic and chronic cluster headache.<br /><br /></span></p> <p><span style="font-size: 10pt;">electroCore chief executive officer and founder JP Errico says: &ldquo;As the results of our studies continue to demonstrate positive results, we are increasingly optimistic that the extensive investment we have made in both pre-clinical trials and clinical trials was a wise use of our capital and human resources. We believe that this therapy is unique in both its safety and efficacy profiles. With few adverse events reported, non-invasive vagus nerve stimulation appears to be the first therapeutic option that offers both acute and prophylactic benefits for patients who suffer frequent and severe headaches. As such, we believe that gammaCore will ultimately move to a first line treatment for these patients, and will continue to conduct the clinical research necessary to support that conclusion.&rdquo;</span></p></div> A new window of opportunity to prevent cardiovascular and cerebrovascular diseases http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/a-new-window-of-opportunity-to-prevent-cardiovascular-and-cerebrovascular-diseases 2014-10-24T16:46:00Z 2014-10-24T16:46:00Z <div id="Introduction3" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Future prevention and treatment strategies for vascular diseases may lie in the evaluation of early brain imaging tests long before heart attacks or strokes occur, according to a systematic review conducted by a team of cardiologists, neuroscientists, and psychiatrists from Icahn School of Medicine at Mount Sinai and published in <em><a href="http://imaging.onlinejacc.org/journal.aspx">JACC Cardiovascular Imaging</a></em>.</strong></span></p> </div><div id="Text13" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Mount Sinai researchers examined all relevant brain imaging studies conducted over the last 33 years. They looked at studies that used every available brain imaging modality in patients with vascular disease risk factors but no symptoms that would lead to a diagnosis of diseased blood vessels in the heart or brain, or periphery.</span><br /><br /></p> <p><span style="font-size: 10pt;">The review demonstrates that patients with high blood pressure, diabetes, obesity, high cholesterol, smoking, or metabolic syndrome, but no symptoms, still had visible signs on their neuroimaging scans of structural and functional brain changes long before the development of any events related to vascular diseases of the heart or brain.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;This is the first time we have been able to disentangle the brain effects of vascular disease risk factors from the brain effects of cardiovascular and cerebrovascular disease and/or events after they develop,&rdquo; says the article&rsquo;s lead author, Joseph I Friedman, associate professor in the Departments of Psychiatry and Neuroscience at Icahn School of Medicine at Mount Sinai. &ldquo;Moreover, subtle cognitive impairment is an important clinical manifestation of these vascular disease risk factor-related brain imaging changes in these otherwise healthy persons.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">Friedman adds that, because diminished cognitive capacity adversely impacts a person&rsquo;s ability to benefit from treatment for these medical conditions, early identification of these brain changes may &ldquo;present a new window of opportunity&rdquo; for doctors to intervene early and improve prevention of advancement from vascular disease risk factors to established cardiovascular and cerebrovascular diseases. His team is currently testing these hypotheses in ongoing studies at Mount Sinai.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;Patients need to start today to control their vascular risk factors, otherwise their brains may forever harbour physical changes leading to devastating heart and vascular conditions impacting their future overall health and even cognitive decline causing diseases like dementia or when it exists it can accelerate Alzheimer&rsquo;s,&rdquo; says study author, Valentin Fuster, director of Mount Sinai Heart, physician-in-chief of The Mount Sinai Hospital, and chief of the Division of Cardiology at Icahn School of Medicine at Mount Sinai. &ldquo;Our publication raises the possibility that these early brain changes are major warning signs of what the future may hold for these asymptomatic patients. These high risk patients, along with their doctors, hold the power to modify their daily vascular risk factors to help halt the future course of the manifestation of their potentially looming cardiovascular diseases.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;We hope our publication serves as a primer for cardiologists and other doctors interpreting the early neuroimaging data of their patients who may be high risk for vascular disease,&rdquo; says senior article author Jagat Narula, director of cardiovascular imaging, professor of medicine and Philip J and Harriet L. Goodhart chair in cardiology at Icahn School of Medicine at Mount Sinai. &ldquo;These subtle brain changes are clues to us physicians that our patients need to start to lower their vascular risk factors always and way before symptoms or a cardiac or brain event happens. This simple step to lower vascular risk factors can have huge impacts on global prevention efforts of cardiovascular diseases.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers identified the following impact of key vascular risk factors on the structural and functional brain health of asymptomatic patients:</span></p> <ul> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Hypertension is associated with globally appreciable brain volume reductions;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Connecting brain fibre abnormalities, reduced brain blood flow and alterations in the normal pattern of synchronised brain activity between different regions;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Diabetes is associated with connecting brain fibre abnormalities, reduced brain blood flow, and alterations in the normal pattern of synchronised brain activity between different regions;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Obesity is associated with brain volume reductions, reduced brain blood flow and metabolism;</span></li> <li><span style="font-size: 10pt;">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; High total cholesterol and low-density lipoprotein cholesterol are associated with brain volume reductions, and connecting brain fibre abnormalities.

Currently, many people with multiple sclerosis are diagnosed in an ad-hoc way and are often misdiagnosed. People with multiple sclerosis can be left for more than a year without having their condition and medication monitored.<br /><br /></span></p> <p><span style="font-size: 10pt;">An audit carried out by the Royal College of Physicians and the Multiple Sclerosis Trust in 2011 found that although some multiple sclerosis patients received excellent care from the NHS, this was not universal and there were variations in both the quality and the quantity of care provided in England and Wales.<br /><br /></span></p> <p><span style="font-size: 10pt;">In an update to the original 2003 guideline, NICE has set out how people with multiple sclerosis can receive better care. Paul Cooper, consultant neurologist at the Greater Manchester Neuroscience Centre, who chaired the NICE guideline group, says: &ldquo;The care someone receives should not depend on where they live. One of the central areas that we have tried to address in the guidance is identifying and recognising inequalities in services and in care throughout the NHS.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">Cooper continues: "In the past some people got access to prompt and appropriate treatment but many did not. Many people with multiple sclerosis were diagnosed perhaps in a rather ad-hoc way without access to specialist advice, or information and support at the time of diagnosis. Many were potentially being misdiagnosed. The other area that we have tried to address is improving access to therapies of proven benefit for this disabling and distressing condition.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">Mark Baker, director of clinical practice at NICE, comments: &ldquo;It&rsquo;s a paradigm-shifting guideline which reshapes much of our advice on multiple sclerosis and its management. It&rsquo;s a full update and it lays out a new framework for the diagnosis and management of people suspected of having multiple sclerosis.&rdquo;<br /><br /></span></p> <p><span style="font-size: 10pt;">In the update, NICE recommends that people with suspected multiple sclerosis should be referred to a consultant neurologist. Multiple sclerosis should not be diagnosed on the basis of MRI findings alone and only a consultant neurologist should make the diagnosis of multiple sclerosis.<br /><br /></span></p> <p><span style="font-size: 10pt;">Every person with multiple sclerosis should have a comprehensive review of all aspects of their care at least once a year and that multidisciplinary teams - made up of multiple sclerosis nurses, GPs, psychologists, and therapists - should oversee the care they receive.<br /><br /></span></p> <p><span style="font-size: 10pt;">The guidance does not recommend the use of the cannabinoid drug Sativex or fampridine as they provide only a modest benefit at a significant cost to the NHS. Sativex costs &pound;50,000 per quality-adjusted life year (QALY), while fampridine costs in the region of &pound;160,000 per QALY. Both are well above NICE&rsquo;s threshold of &pound;30,000 per QALY.<br /><br /></span></p> <p><span style="font-size: 10pt;">Other key recommendations include offering people with multiple sclerosis an appropriate single point of contact to speak about their care, concerns and different treatment options, and encouraging people with multiple sclerosis to exercise. Supervised exercise programmes should be available for those who struggle with mobility and fatigue.</span></p></div> Costs to treat bleeding strokes increases 10 years later http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/costs-to-treat-bleeding-strokes-increases-10-years-later 2014-10-24T14:59:00Z 2014-10-24T14:59:00Z <div id="Introduction6" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Costs to treat strokes caused by bleeding in the brain may increase significantly 10 years later, according to a study in the <em><a href="http://www.heart.org/HEARTORG/">American Heart Association</a></em> journal <em><a href="http://stroke.ahajournals.org/">Stroke</a>. </em>The Australian study is the first to include 10 years of follow-up data on stroke cost estimates</strong>.</span></p> </div><div id="Text16" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Generally, expenses associated with a stroke peak within the first year and decline over time. Previous estimates of lifetime costs in Australia were based on a five-year average and may have underestimated costs, specifically for haemorrhagic strokes.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;Prevention of stroke should be a focus, since the costs of providing care to people who suffer stroke are unlikely to diminish,&rdquo; says Dominique Cadilhac, study senior author and an associate professor and head of the Translational Public Health: Stroke and Ageing Research Centre at Monash University in Victoria, Australia. &ldquo;Much could be gained if we could work to prevent the majority of strokes that are due to modifiable risk factors, such as high blood pressure or diabetes.&rdquo;</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers interviewed 243 ischemic stroke patients and 43 intracerebral haemorrhage patients who had survived for 10 years or more. The patients had participated in an earlier Australian regional study that estimated five-year costs.</span><br /><br /></p> <p><span style="font-size: 10pt;">Researchers found that:</span></p> <ul> <li><span style="font-size: 10pt;">Average annual direct costs for ischaemic stroke remained stable between five to 10 years at about US$5,207.</span></li> <li><span style="font-size: 10pt;">Average annual direct costs for intracerebral haemorrhage stroke increased 31%, from US$5,807 at five years to US$7,607 at 10 years and the overall average lifetime costs per case for intracerebral haemorrhage stroke increased 25%, from US$43,786 to US$54,956.</span></li> <li><span style="font-size: 10pt;">Medication, aged-care facilities and informal care expenses explained the majority of costs at 10 years. Rehabilitation expenses decreased for ischemic stroke.</span></li> </ul> <p><span style="font-size: 10pt;">&ldquo;We did not know that the cost differentials would be so great between ischaemic stroke and interecerebral haemorrhage and that short-term estimates (six-12 months after a first stroke) used to approximate lifetime annual resource use after the first year would not be a good predictor of future costs,&rdquo; says Cadilhac, who is also the head of public health and epidemiology within the Stroke Division of the Florey Institute of Neuroscience and Mental Health and Data Custodian for the Australian Stroke Clinical Registry.</span><br /><br /></p> <p><span style="font-size: 10pt;">The Australian healthcare system is funded through public and private health insurance. However, the way health care is delivered and priced may influence cost differences between the two health systems. For example, if patients in America stay in the hospital longer or are offered different rehabilitation choices to what is available in Australia, estimates may be too low or high.</span><br /><br /></p> <p><span style="font-size: 10pt;">&ldquo;We hope that our findings can be used to influence the need for more primary prevention and to also support assessment of the cost effectiveness of interventions to reduce disability from stroke,&rdquo; Cadilhac comments. &ldquo;In addition, ensuring that the best evidenced-based guideline treatment is provided in hospitals will assist in reducing disability associated with stroke and may, in turn, avoid unnecessary aged-care placements or an undue burden to caregivers.&rdquo;</span></p></div> Codman Neuro launches first disposable forceps with dual irrigation http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/codman-neuro-launches-first-disposable-forceps-with-dual-irrigation 2014-10-22T11:07:00Z 2014-10-22T11:07:00Z <div id="Introduction7" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Codman Neuro has&nbsp;announced the launch of Spetzler Malis dual irrigating disposable non-stick bipolar forceps, the first disposable dual irrigating forceps for neurosurgery.

The median follow-up was 4.2 years. Both techniques were found to be equally good at preventing fatal and disabling strokes, but stented patients were slightly more likely to have minor strokes without long-term effects. The risk of any stroke in five years was 15.2% in the stenting group compared to 9.4% in the endarterectomy group, but the additional strokes were minor and had no impact on long-term quality of life.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;At the moment, stenting is not widely used in the UK due to historical uncertainty over its long-term effectiveness,&rdquo; says study leader Professor Martin Brown from the UCL Institute of Neurology. &ldquo;However, we have now shown that stenting is just as good as endarterectomy for preventing fatal and disabling strokes. We have also shown that the risk of stroke during the procedure is no higher for stenting than for endarterectomy in younger patients. The risks of each procedure are different and will vary depending on the patient, but stenting should be offered as an option to many more patients under the age of 70.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;One of the issues is that there are not many centres in this country that currently offer stenting as an option so the patient choice is not there. Now that we know stenting is effective in the long term, more staff should be trained to carry out the procedure and gain experience. Otherwise there is a vicious cycle where nobody at a centre has stenting experience so patients are only offered endarterectomy and staff cannot learn or observe the procedure. In other countries, stenting is more widespread and the safety of the procedure improves as staff gain experience.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Shamim Quadir, research communications manager at the Stroke Association, says: &ldquo;A transient ischaemic attack, also known as a mini-stroke, can be a warning sign that someone has carotid artery stenosis, and is at risk of having a major stroke.

The results of this study are published in the current issue of the <em><a href="http://jevt.org/doi/full/10.1583/14-4715MR.1" target="_blank">Journal of Endovascular Therapy</a>.</em> The researchers followed nine patients with significant (more than 80%) recurrent restenosis who underwent drug-eluting balloon angioplasty. In this procedure, a drug-eluting balloon is inflated for 60 seconds and delivers the drug paclitaxel, an inhibitor of the exuberant healing process after angioplasty that leads to restenosis.</span></p> <p><span style="font-size: 10pt;"><br />The angioplasty was successful in all 9 patients, with stenosis decreasing from 87% to 6%. These patients had clinical and ultrasound follow-up every three months during the first 24 months after the procedure, then were followed every six months. By approximately 36 months after the drug-eluting balloon angioplasty, only three patients were found to have recurrent in-stent restenosis at 18, 25, and 32 months, respectively, after the initial angioplasty, a far longer interval without restenosis than earlier treatments provided.</span></p> <p><span style="font-size: 10pt;"><br />These three patients underwent another drug-eluting balloon angioplasty procedure and did not experience restenosis at up to14 months after the second procedure. These results show the potential for the drug-eluting balloon treatment to improve outcomes for patients with early recurrent carotid in-stent restenosis.&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />In a related commentary article, the authors discuss lessons learned through this research. Their primary advice is not to wait, but to choose drug-eluting balloon angioplasty for treatment after the first failure of conventional endovascular intervention. They also urge practitioners to keep up to date on the ongoing trials of this treatment.</span></p></div> NeuroSigma partners with US Veterans Administration for eTNS trial http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/neurosigma-partners-with-us-veterans-administration-for-etns-trial 2014-10-16T11:33:00Z 2014-10-16T11:33:00Z <div id="ImageMain12" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/neurosigma-partners-with-us-veterans-administration-for-etns-trial"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/041/NeuroSigma-web_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction12" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>NeuroSigma has announced that it has entered into a Cooperative Research and Development Agreement (CRADA) with the US Veterans Affairs for a clinical trial to evaluate the benefits of non-invasive, external trigeminal nerve stimulation (eTNS) for patients with traumatic brain injury.</strong></span></p> </div><div id="Text112" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Jean-Philippe Langevin, an expert in neurotrauma and a neurosurgeon at the Veterans Affairs Greater Los Angeles (VAGLA) medical centre, will lead the study as principal investigator.&nbsp;The project will enrol US military veterans with traumatic brain injury in an eight-week treatment protocol, and will examine change in cognitive function and regional brain activity as people receive nightly eTNS treatment at home.</span></p> <p><span style="font-size: 10pt;"><br />Traumatic brain injury is a condition that arises after mechanical injury to the brain.

In the last decade, the question of where the disease begins has led researchers to a different part of the human anatomy. In 2003, the German neuropathologist Heiko Braak presented a theory suggesting that the disease begins in the gut and spreads to the brain. The idea has since, despite vocal critics, gained a lot of ground. Researchers at Lund University in Sweden now present the first direct evidence that the disease can actually migrate from the gut to the brain.&nbsp;</strong></span></p> </div><div id="Text117" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The so-called Braak&rsquo;s hypothesis proposes that the disease process begins in the digestive tract and in the brain&rsquo;s centre of smell. The theory is supported by the fact that symptoms associated with digestion and smell occur very early on in the disease.</span></p> <p><span style="font-size: 10pt;"><br />Researchers at Lund University have previously mapped the spread of Parkinson&rsquo;s in the brain. The disease progression is believed to be driven by a misfolded protein that clumps together and &ldquo;infects&rdquo; neighbouring cells. Professor Jia-Yi Li&rsquo;s research team has now been able to track this process further, from the gut to the brain in rat models. The experiment shows how the toxic protein, alpha-synuclein, is transported from one cell to another before ultimately reaching the brain&rsquo;s movement centre, giving rise to the characteristic movement disorders in Parkinson&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We have now been able to prove that the disease process actually can travel from the peripheral nervous system to the central nervous system, in this case from the wall of the gut to the brain.

The findings have been published in the journal <a href="http://www.sciencemag.org/journals" target="_blank"><em>Science</em></a>.</strong></span></p> </div><div id="Text118" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The researchers have shown that following an induced stroke in mice, support cells, so-called astrocytes, start to form nerve cells in the injured part of the brain. Using genetic methods to map the fate of the cells, the scientists could demonstrate that astrocytes in this area formed immature nerve cells, which then developed into mature nerve cells.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;This is the first time that astrocytes have been shown to have the capacity to start a process that leads to the generation of new nerve cells after a stroke,&rdquo; says Zaal Kokaia, professor of Experimental&nbsp;Medical Research at Lund University.</span></p> <p><span style="font-size: 10pt;"><br />The scientists could also identify the signalling mechanism that regulates the conversion of the astrocytes to nerve cells. In a healthy brain, this signalling mechanism is active and inhibits the conversion, and, consequently, the astrocytes do not generate nerve cells. Following a stroke, the signalling mechanism is suppressed and astrocytes can start the process of generating new cells.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Interestingly, even when we blocked the signalling mechanism in mice not subjected to a stroke, the astrocytes formed new nerve cells,&rdquo; says Zaal Kokaia. &ldquo;This indicates that it is not only a stroke that can activate the latent process in astrocytes. Therefore, the mechanism is a potentially useful target for the production of new nerve cells, when replacing dead cells following other brain diseases or damage.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />The new nerve cells were found to form specialised contacts with other cells. It remains to be shown whether the nerve cells are functional and to what extent they contribute to the spontaneous recovery that is observed in a majority of experimental animals and patients after a stroke.</span></p> <p><span style="font-size: 10pt;"><br />A decade ago, Kokaia&rsquo;s and Lindvall&rsquo;s research group was the first to show that stroke leads to the formation of new nerve cells from the adult brain&rsquo;s own neural stem cells. The new findings further underscore that when the adult brain suffers a major blow such as a stroke, it makes a strong effort to repair itself using a variety of mechanisms.</span></p> <p><span style="font-size: 10pt;"><br />The major advancement with the new study is that it demonstrates for the first time that self-repair in the adult brain involves astrocytes entering a process by which they change their identity to nerve cells.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;One of the major tasks now is to explore whether astrocytes are also converted to neurons in the human brain following damage or disease. Interestingly, it is known that in the healthy human brain, new nerve cells are formed in the striatum. The new data raise the possibility that some of these nerve cells derive from local astrocytes. If the new mechanism also operates in the human brain and can be potentiated, this could become of clinical importance not only for stroke patients, but also for replacing neurons which have died, thus restoring function in patients with other disorders such as Parkinson&rsquo;s disease and Huntington&rsquo;s disease,&rdquo; says Olle Lindvall, senior professor of&nbsp;Neurology.</span></p></div> New Envoy catheters launched http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-envoy-catheters-launched 2014-10-11T15:01:00Z 2014-10-11T15:01:00Z <div id="ImageMain19" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-envoy-catheters-launched"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/041/Codman_Envoy_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction19" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Codman Neuro has announced the Europe, Middle East and Africa launch of the EnvoyDA XB Distal Access Guiding Catheter and the 7F Envoy Guiding Catheter for neurovascular procedures.</strong></span></p> </div><div id="Text119" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;To support evolving treatment techniques and the need for versatile access solutions we have expanded our Envoy guide catheter line to provide interventional neuro-radiologists with choice.

The collaborative, which now has funding to proceed with US$5 million in Ice Bucket Challenge funding from The ALS Association, will focus on the following: (1) development of antisense therapy for the C9orf72 gene, the most common genetic cause of ALS, in partnership with Biogen-Idec and ISIS Pharmaceuticals; (2) gene therapy to down regulate SOD1, the second-most common ALS gene; (3) establishment of a Stem Cell and Motor Neuron Core Facility to create clinical-grade induced pluripotent stem (iPS) cell lines, which will be openly shared with the ALS research community. iPS cells have emerged as a key research tool and potential source of therapeutic cells in ALS.( 4) Using a novel screening tool, identify new targets for drug development and in partnership with the industry these leads will be developed further with the potential of new treatment options in the clinic. The Golden West Chapter of The ALS Association has played a key role in the planning and development of this project.</span></p> <p><span style="font-size: 10pt;"><br />Investigators:&nbsp;Don Cleveland, UCSD; Steven Finkbeiner, the Finkbeiner lab at the Gladstone Institutes; Clive Svendsen, Cedar Sinai Medical Center; and collaborators, Martin Marsala, UCSD; and Brian Kaspar, Children&rsquo;s Hospital and Ohio State University.</span></p> <p><span style="font-size: 10pt;"><strong><br />Project MinE</strong></span></p> <p><span style="font-size: 10pt;"><br />Project MinE&nbsp;is a global collaboration with the goal to sequence the genomes of at least 15,000 people with ALS in an effort to discover new genes that affect ALS, either increasing the risk for the disease or protecting against it. The ALS Association&rsquo;s funding commitment of US$1 million will enable Project MinE to expand to the United States.&nbsp;</span><br /> <br /><span style="font-size: 10pt;"> <br />It has become clear that risk for ALS is likely influenced by variants in multiple genes, each of which is relatively rare. The development of advanced sequencing technologies has dramatically reduced the cost of screening large numbers of individuals for these rare variants. Discovering these variants, and understanding how they contribute to disease, or protect against it, is likely to lead to novel approaches to ALS therapies.</span><br /> <br /><span style="font-size: 10pt;"> <br />US investigators:&nbsp;John Landers, University of Massachusetts, Worcester; Jonathan Glass, Emory University.</span><br /> <br /><span style="font-size: 10pt;"> International partners include the Netherlands, United Kingdom, Ireland, Spain, Portugal and Belgium.</span><br /> <br /><span style="font-size: 10pt;"> <br />In addition to the abovementioned collaborative alliances to drive forward ALS research, The ALS Association&rsquo;s Board of Trustees also approved two other projects to expedite the search for treatments and a cure for the disease through care services and public policy efforts.</span></p> <p><span style="font-size: 10pt;"><strong><br />Grants to Certified Treatment Centers of Excellence</strong></span></p> <p><span style="font-size: 10pt;"><br />The ALS Association and its network of chapters currently partner with 43 ALS Association Certified Treatment Centers of Excellence across the United States. Multiple studies have shown the value to a patient of attending a multidisciplinary clinic, including longer survival, increased quality of life, and improved access to potential therapies. One of the requirements in achieving certification through The ALS Association is for the institution to be actively involved in ALS-related research and to provide information to people living with the disease on research outside of their institution. Participation in clinical trials is imperative to the research process to find treatments for the disease. The Ice Bucket Challenge donations have enabled The Association to increase its annual grants to the centres from the presently budgeted US$12,500 to US$25,000 per centre, which was the funding level pre-2008, for the next three years.</span></p> <p><span style="font-size: 10pt;"><strong><br />Regulatory Guidance to Expedite Drug Development</strong></span></p> <p><span style="font-size: 10pt;"><br />Organisations involved in two other neurological diseases (Alzheimer&rsquo;s and Duchenne Muscular Dystrophy) have seen great benefits in working to develop guidance for companies to help them navigate the regulatory pathway for approval of effective therapies. The enactment of the patient-focused drug development elements of the Food and Drug Administration Safety and Innovation Act (FDASIA) presents a unique opportunity for The ALS Association to help expedite drug development by developing similar guidance for ALS. No such guidance exists today for ALS, which creates uncertainty and risk for what is already a difficult and costly process. By developing this guidance, The ALS Association will be able to build on and strengthen its engagement with the FDA, industry and people with ALS about drug development as a regulatory process, which will reduce obstacles that can slow and limit innovation and access to effective treatments.</span></p></div> IMRIS horseshoe headrest named Life Sciences Alley New Technology Showcase winner http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/imris-horseshoe-headrest-named-life-sciences-alley-new-technology-showcase-winner 2014-09-30T18:14:00Z 2014-09-30T18:14:00Z <div id="ImageMain25" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/imris-horseshoe-headrest-named-life-sciences-alley-new-technology-showcase-winner"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/035/IMRIS_horseshoe_headrest_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction25" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>IMRIS announced that its horseshoe headrest has been selected one of 10 New Technology Showcase Winners by Twin Cities-based Life Sciences Alley (LSA), the USA&rsquo;s largest regional medical industry association.

The study results also argue the process can differentiate it from other forms of dementia while the sufferer is still alive. Until now, CTE diagnosis has only been possible by evaluating post-mortem brain tissue.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our data suggest that PET imaging using the [18F]-T807 tau tracer is an effective method of diagnosing or ruling out chronic traumatic encephalopathy in a living brain,&rdquo; says Samuel Gandy, director of the Center for Cognitive Health and NFL Neurological Care at the Icahn School of Medicine at Mount Sinai, USA. &ldquo;Estimates of the prevalence of CTE have varied wildly, with the most recent figure coming from the National Football League who predicts that one in three NFL players will suffer significant brain damage. We can now begin to test this while the players are still alive. Moreover, we are now equipped to tell prospective athletes of all ages some real data on the risks that accompany sports involving repeated traumatic brain injuries.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Signs of CTE were originally spotted in boxers and retired National Football League (NFL) players. Before their deaths, many of these athletes struggled with symptoms like memory loss, depression, and violent outbursts, and in some cases they became suicidal. The NFL is currently helping to launch large-scale studies of the condition. More recently, the brains of ice hockey players and battlefield veterans exposed to repeated bomb blasts have revealed evidence of CTE.</span></p> <p><span style="font-size: 10pt;"><br />In recent years, scientists have developed radiotracers like [18F]-T807 that attach to protein aggregates and emit high-energy particles called positrons that are registered on a PET scanner. The [18F]-T807 tau tracer selectively binds only to tangles of tau in the brain and not to amyloid proteins associated with Alzheimer&rsquo;s disease, making it superior to other proposed tau tracers to date in terms of CTE detection, according to the study authors.</span></p> <p><span style="font-size: 10pt;"><br />The Mount Sinai case study included the evaluations of two living patients, a retired NFL football player with a history of multiple concussions and a patient with a single, severe traumatic brain injury (TBI). Both patients presented with cognitive decline and suspected Alzheimer&rsquo;s disease. Both were evaluated by a combination of molecular imaging techniques to pinpoint specific brain disease and damage.</span></p> <p><span style="font-size: 10pt;"><br />Brain injury, whether as a result of repeated head trauma or a single, traumatic brain event, may jumpstart a process whereby tau protein, which functions in a healthy brain to help stabilise a nerve cell&rsquo;s protein skeleton, breaks off the skeleton and begins to build up inside nerve cells. The theory is that tangles of tau protein accumulate and cause nerve cell damage in the CTE brain.</span></p> <p><span style="font-size: 10pt;"><br />While various dementias like CTE and Alzheimer&rsquo;s disease share many symptoms, the nature and distribution of brain degeneration in chronic traumatic encephalopathy is distinctive from Alzheimer&rsquo;s disease. CTE is characterised by prominent formation inside nerve cells of structures called tangles, a process called a tauopathy. The dementia of CTE occurs in midlife after a latency period of years or decades after exposure to repetitive head trauma.</span></p> <p><span style="font-size: 10pt;"><br />In this study, led by Gandy, both patients underwent neurologic and neuropsychological assessments by a team of traumatic brain injury and Alzheimer&rsquo;s disease experts. Following this comprehensive evaluation, the experts disagreed as to whether Alzheimer&rsquo;s disease was present in this retired NFL player.</span></p> <p><span style="font-size: 10pt;"><br />Both patients underwent PET imaging with florbetapir, another chemical that is FDA-approved to detect the brain amyloid plaques of Alzheimer&rsquo;s disease during life. In the case of the retired NFL player, who suspected he had Alzheimer&rsquo;s disease and presented to the team at Mount Sinai in hope to participate in a clinical study for Alzheimer&rsquo;s disease, the florbetapir PET scan was negative for cerebral amyloidosis, thereby excluding Alzheimer&rsquo;s disease and the possibility of his engaging in a treatment protocol for his suspected, incorrect Alzheimer&rsquo;s disease diagnosis. He also underwent [18F]-T807 PET imaging that revealed signs of aggregated tau in some temporal areas of his brain.</span></p> <p><span style="font-size: 10pt;"><br />The current study is the first where one technology was able to show both the abnormal accumulation of tau protein in a person that experienced several concussions in the distant past, while at the same time demonstrating that the patient did not have the protein signature seen with Alzheimer&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Although we are just now understanding the clinical impact of PET, our use of tauopathy PET imaging to evaluate the progressive alterations in brain proteins for CTE patients already offers us a powerful new tool for evaluation,&rdquo; says Ken Marek, president and senior scientist at Molecular Neuroimaging (MNI) in New Haven, USA, where the [18F]-T807 imaging was performed. &ldquo;In particular, we can directly measure the accumulation of&nbsp;tau protein&nbsp;we believe associated with the devastating symptoms experienced by patients and their families and evaluate the disease during life in ways that were previously only available to the pathologist&rsquo;s microscope.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />A tauopathy imaging programme at Mount Sinai Hospital is expected to commence in early October 2014.</span></p> <p><span style="font-size: 10pt;">Researchers from the University of Virginia also contributed to the study.</span></p></div> EBS expands commercialisation of Next Wave non-invasive electrical brain stimulation device http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/ebs-expands-commercialisation-of-next-wave-non-invasive-electrical-brain-stimulation-device 2014-09-24T11:17:00Z 2014-09-24T11:17:00Z <div id="Introduction29" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>EBS Technologies has&nbsp;announced that it has opened its first ophthalmologic clinical site in Germany that is offering the use of the EBS&nbsp;Next Wave<em>&nbsp;</em>brain stimulation device designed to expand the visual field of patients with impaired vision caused by glaucoma, stroke and other neurological diseases.</strong></span></p> </div><div id="Text129" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Last week, EBS announced that a clinical study (&ldquo;Brain functional connectivity network breakdown and restoration in blindness&rdquo;) published in the journal&nbsp;<em>Neurology</em>&nbsp;validates non-invasive brain stimulation for restoring partial vision to an impaired eye; the company&rsquo;s&nbsp;Next Wave&nbsp;system is a non-invasive brain stimulation device that is designed to expand the visual field of patients with impaired vision caused by glaucoma, stroke or other neurological disorders.

While calling for further research in key areas, Clement Hamani of Toronto Western Hospital and co-authors emphasise that patients with OCD symptoms that do not respond to other treatments should continue to have access to deep brain stimulation.</span></p> <p><span style="font-size: 10pt;"><br />Hamani led a multispecialty expert group in performing a systematic review of research on the effectiveness of deep brain stimulation for OCD. Deep brain stimulation&mdash;placement of electrodes in specific areas of the brain, followed by electrical stimulation of those areas&mdash;has become an important treatment for patients with Parkinson&rsquo;s disease and other movement disorders.</span></p> <p><span style="font-size: 10pt;"><br />Although many patients with OCD respond well to medications and/or psychotherapy, 40 to 60% continue to experience symptoms despite treatment. Over the past decade, a growing number of reports have suggested that deep brain stimulation may be an effective alternative in these &ldquo;medically refractory&rdquo; cases.</span></p> <p><span style="font-size: 10pt;"><br />Hamani and colleagues were tasked with analysing the supporting evidence and developing an initial clinical practice guideline for the use of deep brain stimulation for patients with OCD. The review and guideline development process was sponsored by the American Society of Stereotactic and Functional Neurosurgery and the CNS. Out of more than 350 papers, the reviewers identified seven high-quality studies evaluating deep brain stimulation for OCD.</span></p> <p><span style="font-size: 10pt;"><br />Based on that evidence, they conclude that bilateral stimulation (on both sides of the brain) of two brain &ldquo;targets&rdquo;&mdash;areas called the subthalamic nucleus and the nucleus accumbens&mdash;can be regarded as effective treatments for OCD. In controlled clinical trials, both techniques improved OCD symptoms by around 30% on a standard rating scale.</span></p> <p><span style="font-size: 10pt;"><br />That evidence forms the basis for a clinical guideline stating that bilateral deep brain stimulation is a &ldquo;reasonable therapeutic option&rdquo; for patients with severe OCD that does not respond to other treatments. The guideline also notes that there is &ldquo;insufficient evidence&rdquo; supporting the use of any type of unilateral deep brain stimulation target (one side of the brain) for OCD.</span></p> <p><span style="font-size: 10pt;"><br />The review highlights the difficulties of studying the effectiveness of deep brain stimulation for OCD&mdash;because most patients respond to medical treatment, studies of this highly specialised treatment typically include only small numbers of patients. Hamani and co-authors identify some priorities for future research: particularly to identify the most effective brain targets and the subgroups of patients most likely to benefit.</span></p> <p><span style="font-size: 10pt;"><br />Despite the limited evidence base, deep brain stimulation therapy for OCD has been approved by the Food and Drug Administration under a humanitarian device exemption. Hamani and co-authors note that various safeguards are in place to ensure appropriate use, and prevent overuse, of deep brain stimulation for OCD.</span></p> <p><span style="font-size: 10pt;"><br />While research continues, they believe that functional neurosurgeons should continue to work with other specialists to ensure that patients with severe, medically refractory OCD continue to have access to potentially beneficial deep brain stimulation therapy.</span></p></div> ATL1102 phase II trial results published in Neurology http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/atl1102-phase-ii-trial-results-published-in-neurology 2014-09-23T17:00:00Z 2014-09-23T17:00:00Z <div id="Introduction33" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Antisense Therapeutics has reported the publication of previously generated phase IIa clinical trial data on ATL1102 in the medical journal <a href="http://www.neurology.org/" target="_blank"><em>Neurology</em></a>.</strong></span></p> </div><div id="Text133" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">The article titled &ldquo;CD49d antisense drug ATL1102 reduces disease activity in patients with relapsing-remitting MS&rdquo;, is currently available online and will be included in the print edition Volume 83, November 11, 2014.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The article highlights the successful outcomes of the Phase IIa clinical trial of ATL1102 in Multiple Sclerosis (MS) patients where in the randomised, double-blind, placebo-controlled study in 77 patients with relapsing-remitting multiple sclerosis (RRMS), ATL1102 met its primary end point after only two months of dosing, showing a significant reduction, by 54.4% (p=0.01) in the cumulative number of new active brain lesions in patients taking ATL1102 compared to placebo.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The efficacy outcomes from this study were viewed to be as good as, or superior to, those achieved with MS drug Tysabri at a similar stage in its clinical development. Tysabri (natalizumab) is a monoclonal antibody drug targeting the VLA-4 receptor (same target as ATL1102). In 2013, Tysabri generated sales in excess of US$1.6 billion.

Any imbalance in this pathway (too much or too little activity) leads to disease &mdash; the overgrowth of cells in cancer is one example of overactivation of this pathway.</span></p> <p><span style="font-size: 10pt;"><br />While much research on Wnt has focused on diseases involved in overactive Wnt signalling, Bu&rsquo;s team is one of the first to demonstrate the link between suppressed Wnt signalling and Alzheimer&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our finding makes sense, because researchers have long known that patients with cancer are at reduced risk of developing Alzheimer&rsquo;s disease, and vice versa,&rdquo; Bu says. &ldquo;What was not known is that Wnt signalling was involved in that dichotomy.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Using a new mouse model, the investigators discovered the key defect that leads to suppressed Wnt signalling in Alzheimer&rsquo;s. They found that the low-density lipoprotein receptor-related protein 6 (LRP6) is deficient, and that LRP6 regulates both production of amyloid beta, the protein that builds up in the brains of Alzheimer&rsquo;s disease patients, and communication between neurons. That means lower than normal levels of LRP6 leads to a toxic buildup of amyloid and impairs the ability of neurons to talk to each other.</span></p> <p><span style="font-size: 10pt;"><br />Mice without LRP6 had impaired Wnt signalling, cognitive impairment, neuroinflammation and excess amyloid.</span></p> <p><span style="font-size: 10pt;"><br />The researchers validated their findings by examining post-mortem brain tissue from Alzheimer&rsquo;s patients &mdash; they found that LRP6 levels were deficient and Wnt signalling was severely compromised in the human brain they examined.</span></p> <p><span style="font-size: 10pt;"><br />The good news is that specific inhibitors of this pathway are already being tested for cancer treatment. &ldquo;Of course, we do not want to inhibit Wnt in people with Alzheimer&rsquo;s or at risk for the disease, but it may be possible to use the science invested in inhibiting Wnt to figure out how to boost activity in the pathway,&rdquo; Bu says.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Identifying small molecule compounds to restore LRP6 and the Wnt pathway, without inducing side effects, may help prevent or treat Alzheimer&rsquo;s disease,&rdquo; he says. &ldquo;This is a really exciting new strategy &mdash; a new and fresh approach.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Researchers from the University of Kentucky, Xiamen University in China, the University of Oklahoma and the Korea Brain Research Institute participated in the study.</span></p></div> CE mark for Vercise deep brain stimulation system for patients with tremor http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/ce-mark-for-vercise-deep-brain-stimulation-system-for-patients-with-tremor 2014-09-18T16:09:00Z 2014-09-18T16:09:00Z <div id="ImageMain37" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/ce-mark-for-vercise-deep-brain-stimulation-system-for-patients-with-tremor"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/037/Vercise_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction37" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Boston Scientific has received CE mark approval for the Vercise deep brain stimulation system for the treatment of tremor, including the most common form of this movement disorder known as essential tremor.

This paper provides the first indication that the measurement of brain motion due to pulsatile blood flow can detect physiological changes in the brain correlated with concussion. Out of 84 players enrolled in the Stanford University Medical School Institutional Review Board-approved protocol, BrainPulse detected 10 out of 13 confirmed concussions for a 77% sensitivity; and 79 out of 91 recordings were confirmed to not have a concussion for an 87% specificity.</strong></span></p> </div><div id="Text144" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Paul Lovoi, founder and chief executive officer of Jan Medical, states, &ldquo;While these findings are very encouraging, additional trials will be necessary to establish this technology as an objective measure of concussion, studies that we are currently undertaking.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The study was conducted at a Northern California high school over the course of one football season involving the majority of both the varsity and junior varsity players.

The Nautilus BrainPulse from Jan Medical is designed to measure the normal brain pulse as well as disruptions of the brain pulse. By digitising the signal patterns from headset-mounted sensors measuring the skull&rsquo;s motion, and extracting features from them, algorithms can be developed to identify normal and a variety of abnormal brain pulse patterns. The BrainPulse sensors passively measure the skull in recording sessions that take approximately three minutes to conduct.

The technology utilises advanced signal processing methods and classification algorithms that quantify and characterise features of brain electrical activity associated with traumatic brain injury.</span></p> <p><span style="font-size: 10pt;"><br />In this prospective validation study, ten minutes of brain electrical activity were recorded in 46 adult patients with traumatic haematomas with measureable blood (CT scan positive, &ge;1cc of blood) and 278 head-injured control patients (CT scan negative). The mild presentation of the entire study population is reflected by 97% (313/324) of the patients in the study having a normal Glasgow Coma Scale score of 15 (on a scale of 3&ndash;15), with a mean value of 14.7 for the population with haematomas, and 14.9 for the control group. The volume of blood and distance from recording electrodes were measured by blinded independent experts. A previously derived classification algorithm developed by BrainScope (the &ldquo;TBI-index&rdquo;) was used to identify the probability of a traumatic CT positive lesion in this clinically important independent population.</span></p> <p><span style="font-size: 10pt;"><br />The study reported a sensitivity of 96% to haematomas, which was independent of type of haematoma, blood volume, or distance of the bleed from the recording electrodes on the forehead. Because of the life-threatening risk associated with undetected haematomas, specificity was permitted to be lower (44%) in exchange for extremely high sensitivity. In this study population (n=324), all subjects had been referred for CT scanning by standard clinical practice, of whom 278 were found to be CT negative. These results replicate previously peer-reviewed published findings (Hanley and colleagues, <em>Journal of Neurotrauma</em>, 2013) using the technology in traumatic haematomas, and again importantly demonstrated that the distance and volume restrictions noted with other commercially available methods for detecting traumatic intracranial haematomas were not limitations of BrainScope&rsquo;s technology. These results lend further strong support to the potential enhanced clinical utility of the BrainScope TBI-Index as an important adjunct to acute assessment and triage of clinically important (potentially life-threatening) brain injuries.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Often patients such as those in this study present with very mild symptoms of traumatic brain injury and therefore pose difficult triage decisions upon clinical evaluation. It is not always clear whether the patient might have a clinically important traumatic brain injury (blood in the brain) requiring further clinical evaluation.

They add that high-resolution neuroimaging and invasive electrographic studies could be beneficial.</span></strong></p> </div><div id="Text152" style="clear:both; text-align:left"><p>According to the study&rsquo;s lead author, Dario J Englot there is differences in epilepsy type and pathological substrates between children and adults. He explains that because young children have greater neural plasticity and potential for neurological recovery than adults, extremely aggressive resection such as hemispherectomy would be devastating in an adult, adding that critical functions such as language and motor abilities are more likely to improve post-operatively in a young child, due to reorganisation of eloquent cortex.<br /><br />However, they say that, although resection is a tried and tested treatment method, some patients continue to experience seizures post-surgery.<br /><br />Englot and colleagues performed a retrospective cohort study of children and adolescents who underwent focal respective surgery to determine the reasons for surgical failure. They also performed quantitative and qualitative analyses of factors associated with persistent post-operative seizures. The results were published in the <a href="http://thejns.org/loi/ped" target="_blank"><em>Journal of Neurosurgery: Pediatrics</em></a>.<br /><br />They reviewed data from 110 patients (115 resections) and found that 76% of patients were free from disabling seizures (Engel Class I outcome) at a mean follow-up of 3.1 years.<br /><br />They say that freedom from seizures was predicted by temporal lobe surgery compared with extratemporal resection, tumour or mesial temporal sclerosis compared with cortical dysplasia or other pathologies and by a lower preoperative seizure frequency.<br /><br />From their findings, it was demonstrated that factors associated with persistent seizures (Engel Class II&ndash;IV outcome) were residual epileptogenic tissue adjacent to the resection cavity (40%), an additional epileptogenic zone distant from the resection cavity (32%), and the presence of a hemispheric epilepsy syndrome (28%).<br /><br />&ldquo;While seizure outcomes in paediatric epilepsy surgery may be improved by the use high-resolution neuroimaging and invasive electrographic studies, a more aggressive resection should be considered in certain patients&rdquo;, Englot <em>et al</em> state.<br /><br />They conclude that aggressive resection should extend to hemispherectomy, if a hemispheric epilepsy syndrome is suspected. Englot told <em>NeuroNews</em>: &ldquo;While it is critical to carefully tailor resections to avoid neurological deficits, it is also true that seizure-freedom is the strongest predictor of quality of life. In our view, an aggressive resection involves maximal removal of tissue that is involved in the epileptogenic zone, while preserving eloquent brain regions to the greatest extent possible. For example, in a child with epilepsy caused by a benign brain tumour (e.g. ganglioglioma), a limited resection might involve lesionectomy alone, while an aggressive resection may include intraoperative interictal electrocorticography to delineate epileptogenic peri-tumoral cortex which should also be removed.&rdquo;<br /><br />They add that the patient should receive counselling on treatment expectations as reoperation may be required in some cases.</p> </div> Highest level evidence indicates better outcomes when using iMRI for brain tumour surgery http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/highest-level-evidence-indicates-better-outcomes-when-using-imri-for-brain-tumour-surgery- 2014-08-26T16:37:00Z 2014-08-26T16:37:00Z <div id="ImageMain53" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/highest-level-evidence-indicates-better-outcomes-when-using-imri-for-brain-tumour-surgery-"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/041/iMRI-web.jpg" border="0" vspace="5" /></a></div><div id="Introduction53" style="clear:both;"> <p><strong><span style="font-size: 11pt;">In a recently published article in the journal <a href="http://journals.lww.com/neurosurgery/pages/default.aspx" target="_blank"><em>Neurosurgery</em></a> the use of VISIUS intraoperative MRI (iMRI) in brain tumour surgery has been proven to result in complete tumour removal in more patients with glioma tumours.&nbsp;</span></strong></p> </div><div id="Text153" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Led by Jin-song Wu, the neurosurgical team at Huashan Hospital at Fudan University in Shanghai, China, conducted the study.</span><br /><br /><span style="font-size: 10pt;">The prospective, parallel, randomised, triple-blind controlled trial design provides the most objective data and therefore highest level evidence to date of the value of iMRI in treating both low and high-grade gliomas.

Other published studies on high-field iMRI have been mainly retrospective.</span><br /><br /><span style="font-size: 10pt;">&ldquo;iMRI is a practical and valuable asset to increasing the extent of resection for cerebral gliomas, with a specific significant influence for low grade gliomas,&rdquo; Wu says. &ldquo;With trends to statistical significance, these early results are the highest level of iMRI evidence for glioma surgery now available. This leads to more improved overall survivability and quality of life than using conventional neuronavigation.&rdquo;</span><br /><br /><span style="font-size: 10pt;">The low-grade glioma (LGG) subgroup patients who were treated in a VISIUS Surgical Theatre using iMRI had a statistically significant complete resection rate of 82% compared to 43% for the control group of conventional surgery patients.

Although there is no cure yet, a timely diagnosis is useful for people with dementia to get access to current treatment, services and support, both medical and non-medical.

Returned pictures are reconstructed into 3D images using algorithms developed by Menon and Kim.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Unlike miniature microscopes, our approach does not use optics,&rdquo; Menon says. &ldquo;It&rsquo;s primarily computational.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />He says this approach will allow researchers not only to take images far smaller than those taken by current miniature microscopes, but do it for a fraction of the cost.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We can get approximately 1-micron-resolution images that only US$250,000 and higher microscopes are capable of generating,&rdquo; Menon says. &ldquo;Miniature microscopes are limited to the few tens of microns.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Menon hopes to extend the technology in the future so it can see details down to submicron resolutions, compared with the current 1.4 microns. (A micron is a millionth of a metre.

The&nbsp;study&nbsp;was published in the July issue of the&nbsp;<em><a href="http://www.nature.com/jcbfm/index.html" target="_blank">Journal of Cerebral Blood Flow &amp; Metabolism</a>.</em></strong></span></p> </div><div id="Text160" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;This is an important breakthrough in getting drugs delivered to specific parts of the brain precisely, non-invasively, and safely, and may help in the treatment of central nervous system diseases like Parkinson&rsquo;s and Alzheimer&rsquo;s,&rdquo; says Konofagou, whose National Institutes of Health Research Project Grant (R01) funding was just renewed for another four years for an additional US$2.22 million. The award is for research to determine the role of the microbubble in controlling both the efficacy and safety of drug safety through the BBB with a specific application for treating Parkinson&rsquo;s disease.</span></p> <p><span style="font-size: 10pt;"><br />Most small&mdash;and all large&mdash;molecule drugs do not currently penetrate the blood-brain barrier that sits between the vascular bed and the brain tissue. &ldquo;As a result,&rdquo; Konofagou explains, &ldquo;all central nervous system diseases remain undertreated at best. For example, we know that Parkinson&rsquo;s disease would benefit by delivery of therapeutic molecules to the neurons so as to impede their slow death. But because of the virtually impermeable barrier, these drugs can only reach the brain through direct injection and that requires anaesthesia and drilling the skull while also increasing the risk of infection and limiting the number of sites of injection. And transcranial injections rarely work&mdash;only about one in ten is successful.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Focused ultrasound in conjunction with microbubbles&mdash;gas-filled bubbles coated by protein or lipid shells&mdash;continues to be the only technique that can permeate the BBB safely and non-invasively. When microbubbles are hit by an ultrasound beam, they start oscillating and, depending on the magnitude of the pressure, continue oscillating or collapse. While researchers have found that focused ultrasound in combination with microbubble cavitation can be successfully used in the delivery of therapeutic drugs across the BBB, almost all earlier studies have been limited to one specific-sized agent that is commercially available and widely used clinically as ultrasound contrast agents. Konofagou and her team were convinced there was a way to induce a size-controllable BBB opening, enabling a more effective method to improve localised brain drug delivery.</span></p> <p><span style="font-size: 10pt;"><br />Konofagou targeted the hippocampus, the memory centre of the brain, and administered different-sized sugar molecules (Dextran). She found that higher acoustic pressures led to larger molecules accumulating into the hippocampus as confirmed by fluorescence imaging. This demonstrated that the pressure of the ultrasound beam can be adjusted depending on the size of the drug that needs to be delivered to the brain: all molecules of variant sizes were able to penetrate the opened barrier but at distinct pressures, ie., small molecules at lower pressures and larger molecules at higher pressures.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Through this study, we have been able to show, for the first time, that we can control the BBB opening size through the use of acoustic pressure,&rdquo; says Konofagou. &ldquo;We have also learned much more about the physical mechanisms associated with the trans-BBB delivery of different-sized agents, and understanding the BBB mechanisms will help us to develop agent size-specific focused ultrasound treatment protocols.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Konofagou and her&nbsp;Ultrasound Elasticity Imaging Laboratory&nbsp;team plan to continue to work on the treatment of Alzheimer&rsquo;s and Parkinson&rsquo;s in a range of models, and hope to test their technique in clinical trials within the next five years.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;It is frightening to think that in the 21<sup>st</sup>&nbsp;century we still have no idea how to treat most brain diseases,&rdquo; Konofagou adds. &ldquo;But we are really excited because we now have a tool that could potentially change the current dire predictions that come with a neurological disorder diagnosis.&rdquo;</span></p></div> electroCore appoints Piper Jaffray to deal with growing interest from pharma http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/electrocore-appoints-piper-jaffray-to-deal-with-growing-interest-from-pharma 2014-08-19T10:29:00Z 2014-08-19T10:29:00Z <div id="ImageMain61" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/electrocore-appoints-piper-jaffray-to-deal-with-growing-interest-from-pharma"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/036/gammaCore_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction61" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>electroCore has appointed Piper Jaffray to assist in discussions with pharma companies who are interested in partnering with it on the commercialisation of its breakthrough non-invasive vagus nerve (nVNS) stimulation therapy.</strong></span></p> </div><div id="Text161" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;The interest from pharma, medical devices and even technology companies has grown considerably over the last six months,&rdquo; comments chief executive officer and founder JP Errico. &ldquo;We wanted to explore all the opportunities for our future, from partnership to remaining independent. We therefore had discussions with several banks to help us with this process and chose Piper Jaffray. We are under no pressure to do a deal as we are fully funded until 2016.

The study further suggests that patients who remained on therapy for longer periods of time, may enjoy progressively larger decreases in headache days over the period they are on therapy.</span></p> <p><span style="font-size: 10pt;"><br />Earlier in June electroCore reported preliminary results of a multicentre, randomised, trial across Europe. The trial was found to have met its primary endpoint of statistical significance in reducing the number of cluster headache attacks when compared with the standard of care. During weeks three and four following the beginning of therapy, the number of cluster headache attacks per week was reduced by 46.3% in patients treated with nVNS compared with 12.5% (p=0.002) in patients treated with the best available standard of care.</span></p> <p><span style="font-size: 10pt;"><br />Charly Gaul, director of the Migraine and Headache Clinic K&ouml;nigstein, Germany and the principal investigator of this study comments; &ldquo;This study is one of the few well controlled, randomised studies of any preventative treatment for cluster headache.

Accordingly, the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), the regulating agency that certifies Primary and Comprehensive Stroke Centres, requires that these institutions establish written care protocols to guide performance in the emergency care of acute ischaemic stroke, a press release from SNIS states.</span><br /><br /><span style="font-size: 10pt;">The study details a 2012 initiative by VUMC, an Advanced Certification Comprehensive Stroke Center, to significantly revise its stroke care protocol. &ldquo;Our ultimate goal was to develop an enhanced protocol that eliminates variability in our process, streamlines care to achieve necessary efficiencies, and improves time delays to improve the potential for better patient outcomes,&rdquo; said J Mocco, associate professor of Neurosurgery, Vanderbilt University Medical Center.</span><br /><br /><span style="font-size: 10pt;">The new protocol specifies three phases of activities involved in patient assessment and treatment decisions, as well as corresponding communication to relevant physicians at every phase. Specific measurements that map to the three phases include: time from patient arrival to CT scanning; time from patient arrival to neurology evaluation of diagnostics; and time from patient arrival to treatment with intravenous tissue plasminogin activator (IV tPA). Data was obtained over four separate three-month time periods pre- and post-protocol for comparison (pre-implementation of protocol: January&ndash;March 2012, and post-implementation of protocol: August&ndash;October, 2012; January&ndash;March, 2013; and September &ndash; November, 2013). &ldquo;These categories had been measured as part of our original protocol," continued Mocco, "however, we saw an opportunity to focus attention on some of the sub-processes within each that typically do not command attention, but, if addressed, could make a meaningful difference in quality improvement and the overall result.&rdquo;</span><br /><br /><span style="font-size: 10pt;">Post-implementation of the protocol, an analysis across all categories showed notable progress, with average time from patient arrival to CT scanning decreasing from 40.4 to 13 minutes; average time from patient arrival to neurology evaluation of diagnostics decreasing from 34.3 to 8.3 minutes; and average time from patient arrival to IV tPA treatment decreasing from 67.6 to 46.5 minutes.&nbsp; The latter means that VUMC has successfully met the JCAHO-stipulated metric of 60 minutes for "patient arrival to IV tPA."</span></p> <p><span style="font-size: 10pt;">"The success of this new protocol can truly be attributed to a multidisciplinary effort on the part of all of our physicians and other clinicians who work within the always complex and dynamic environment of emergency stroke care with ever-changing variables, all for the purpose of providing the best care for our stroke patients," said Scott Zuckerman, a senior neurosurgery resident who helped plan and lead the implementation of the protocol.</span><br /><br /><span style="font-size: 10pt;">Mocco added, &ldquo;First and foremost, it illustrates the value of customised written protocols that consider all of the nuances associated with any one hospital&rsquo;s emergency stroke care process. Ours is certainly not a one-size fits all solution. Every stroke centre has to tailor its protocols to its own culture and resources.&nbsp; But, ultimately, we hope our experience will be of benefit to other stroke centres that are considering or just beginning a written protocol initiative to fulfill their mission of offering the highest standard of stroke care to their patients.&rdquo;</span></p></div> NeuroPace RNS system receives approval from CMS for new Technology Add-On Payments http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/neuropace-rns-system-receives-approval-from-cms-for-new-technology-add-on-payments 2014-08-06T11:18:00Z 2014-08-06T11:18:00Z <div id="ImageMain67" style="clear:both;" align="center"><a href="http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/neuropace-rns-system-receives-approval-from-cms-for-new-technology-add-on-payments"><img src="http://www.cxvascular.com/AcuCustom/Sitename/DAM/039/NeuroPace_main_Main.jpg" border="0" vspace="5" /></a></div><div id="Introduction67" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>NeuroPace has announced that the Centers for Medicare &amp; Medicaid Services (CMS) has approved New Technology Add-on Payments (NTAP) for the RNS system, the world&rsquo;s only commercially available implantable closed-loop responsive neurostimulator system. The NTAP programme recognises new technologies that provide substantial clinical improvement over existing therapies, and is designed to support timely access to innovative technologies for Medicare beneficiaries.</strong></span></p> </div><div id="Text167" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">NeuroPace received premarket approval (PMA) from the US Food and Drug Administration (FDA) for the RNS system in November 2013. It is approved as a treatment for adults with partial onset seizures with one or two seizure onset zones whose seizures have not been controlled with two or more antiepileptic drugs.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;We are grateful CMS recognises the substantial benefits the RNS system has provided to patients and the need for patients who suffer from uncontrolled seizures to have access to this therapy,&rdquo; says Frank Fischer, chief executive officer at NeuroPace. &ldquo;Epilepsy centres have moved quickly since PMA approval to make the RNS system available. To date, 35 Comprehensive Epilepsy Centers that meet all the qualifications for the highest level of epilepsy care have completed required training and are able to implant the RNS system.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Approximately 2.3 million adults in the United States have active epilepsy, and one-third live with seizures because existing therapies have not provided seizure control. Many people with uncontrolled seizures have or are eligible for Medicare disability benefits. Approval of the NTAP will significantly improve patient access to this new technology.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />As a closed-loop system, the RNS System monitors the brain&rsquo;s own signals, interprets those signals, provides stimulation when needed, and then assesses the brain&rsquo;s response. The breakthrough aspect of the RNS system is its advanced detection and stimulation capabilities. This is unlike all other existing neurostimulation therapies, which continuously or intermittently stimulate the brain without determining the need for treatment or monitoring the response.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The RNS system has been evaluated in three clinical trials, including a prospective, randomised, double-blinded, sham stimulation controlled pivotal study. Results of the clinical trials demonstrate that the substantial clinical improvements experienced by patients over the short- and long-term are durable over many years of therapy. At this time, some patients have been treated with the RNS system for over ten years, and more than 1,500 patient years of experience with responsive neurostimulation have been accumulated to date.</span></p></div> Accenture and Philips announce proof of concept app for ALS patients http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/accenture-and-philips-announce-proof-of-concept-app-for-als-patients 2014-08-05T11:49:00Z 2014-08-05T11:49:00Z <div id="Introduction68" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Royal Philips and Accenture have announced that they have developed proof of concept software connecting a wearable display to Emotiv Insight Brainware that could ultimately give more independence to patients with amyotrophic lateral sclerosis (ALS) and other neurodegenerative diseases. Affecting more than 400,000 people per year, ALS, also known as Lou Gehrig&rsquo;s disease, impairs brain and spinal cord nerve cells, gradually diminishing voluntary muscle action. Late-stage patients often become totally paralysed while retaining brain functions.</strong></span></p> </div><div id="Text168" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">&ldquo;This proof of concept exemplifies how people, devices, data and technology could be brought together quickly to connect beyond the hospital walls in a way that can potentially help improve the quality of life for patients, wherever they are in their journey,&rdquo; says Jeroen Tas, chief executive officer, Healthcare Informatics Solutions and Services for Philips. &ldquo;Philips will continue to collaborate with innovative technology companies such as Accenture to explore new wearable and sensor solutions that change peoples&rsquo; lives and create a healthier future.&rdquo;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><strong><br />How it works</strong></span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />When a wearable display and the Emotiv Insight Brainware, which scans EEG brainwaves, are connected to a tablet, users can issue brain commands to control Philips products including Philips Lifeline Medical Alert Service, Philips SmartTV (with TP Vision), and Philips Hue personal wireless lighting. The tablet also allows control of these products using eye and voice commands. In both cases, a person could communicate preconfigured messages, request medical assistance, and control TVs and lights. Accenture and Philips developed the software that enables the integration and interaction between these multiple technologies.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The proof of concept application demonstrates how existing technology could be used to transform the quality of life for ALS patients. When patients lose muscle control and eye tracking ability, they can still potentially operate the Philips suite of connected products in their home environment through brain commands. The Emotiv technology uses sensors to tune in to electric signals produced by the wearer&rsquo;s brain to detect, in real-time, their thoughts, feelings and expressions. The wearable display provides visual feedback that allows the wearer to navigate through the application menu.</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />The Accenture Technology Labs in San Jose, California, USA collaborated with the Philips Digital Accelerator Lab in the Netherlands to create the software to interact with the Emotiv Insight Brainware and the wearable display.

The MRI-guided procedures were performed at 1.5T (magnetic field strength of a standard clinical MRI scanner) using a balanced steady-state free precession sequence in the type of clinical MRI scanner available in most hospitals.&nbsp;</span></p> <p><span style="font-size: 10pt;">&nbsp;</span></p> <p><span style="font-size: 10pt;"><br />Results showed that MARC was clearly visible under MRI guidance and was used to successfully complete 192 (80%) of 240 total turns around blood vessels as compared to the manually- directed catheter under both MRI and x-ray guidance, at 144 (60%) of 240 total turns and 119 (74%) of 160 total turns, respectively. MARC also was faster than the manually directed catheter under MRI, with a mean procedure time of 37 seconds per turn as compared to 55 seconds, but comparable to the manually directed catheter under X-ray guidance which required a mean of 44 seconds for each turn.

On 12 June, six weeks after surgery at CHLA, the device was activated with positive results at the Department of Otolaryngology &ndash; Head &amp; Neck Surgery clinic at Keck Medicine of USC.</span></p> <p><span style="font-size: 10pt;"><br />Auguste&rsquo;s surgery, device activation and future behavioural study are part of a five-year clinical trial in which 10 devices will be implanted in deaf children under the age of five and studied over the course of three years. The Los Angeles study, co-led by audiologist Laurie Eisenberg, and surgeon Eric Wilkinson, is the only in the United States to be supported by the NIH.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;Our Los Angeles-based team has been at the forefront of ABI technology development since it came into use in the late 1970s for adults, so it is especially gratifying to help break the &lsquo;sound barrier&rsquo; once again; this time, for children who previously could not hear,&rdquo; says Eisenberg, a Keck School of Medicine of USC otolaryngology professor. &ldquo;Surgeons outside the United States have been doing ABI surgeries in children for 10 years, but there has never been a formal safety or feasibility study under regulatory oversight. Our team is writing the manuals for all the procedures for this technology, and we have a top-notch multidisciplinary team in place to carry out the research.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />The surgical team that performed the operation at Children&rsquo;s Hospital included Wilkinson, HMRI research scientist and neurotologist at House Clinic; HMRI research scientist and House Clinic neurosurgeon Marc Schwartz, and paediatric neurosurgeon&nbsp;Mark D Krieger, Billy and Audrey Wilder chair, Division of Neurosurgery&nbsp;at CHLA. Attending the surgery was also Vittorio Colletti, of the University of Verona Hospital, Verona, Italy, who has performed the most ABI surgeries on children overseas and is a collaborator on the study.</span></p> <p><span style="font-size: 10pt;"><br />The study&rsquo;s goal is to establish safety and efficacy protocols for the surgery and subsequent behavioural mapping procedures that doctors in the United States can then later utilise once the surgery is approved for children in the USA.</span></p> <p><span style="font-size: 10pt;">&ldquo;Hundreds of children in the USA can benefit from ABI surgery,&rdquo; says Krieger, who also is associate professor of clinical neurosurgery at the Keck School of Medicine of USC. &ldquo;These children would otherwise never hear or develop verbal speech in their lives.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />Auguste was the first child accepted into the Los Angeles study. Thirty-six days after the May 6 surgery at CHLA, his parents watched as audiologists Margaret Winter, and Jamie Glater, from the USC Center for Childhood Communication activated the device implanted in Auguste&rsquo;s brainstem. When Winter delivered tiny pulses of electric current to the electrodes in his brain, the toddler lifted his head indicating he heard a sound.</span></p> <p><span style="font-size: 10pt;"><br />Auguste has been deaf since birth. At 22 months, he underwent a bilateral cochlear implant, which uses electrodes to stimulate auditory nerves, but the device did not help him hear because he does not have a cochlear, or hearing, nerve. Auguste travelled with his parents, Sophie and Christophe, from Montreal to Los Angeles to participate in the clinical trial. The NIH grant covers the costs of the device, procedure and subsequent testing. To qualify for participation, patients must show that standard treatment such as hearing aids and cochlear implants have been ineffective.</span></p> <p><span style="font-size: 10pt;"><br />During the six-hour surgery in May, doctors made an incision by Auguste&rsquo;s right ear and removed his right cochlear implant before implanting the ABI device on his brainstem. The ABI device has external and internal parts. The external parts, which consist of a processor with a microphone and transmitter, transform sound into electrical signals and transmit the signals to an internal receiver that is part of the electrode array. The electrode array is placed on the cochlear nucleus of the brainstem. The procedure is considered revolutionary because it stimulates neurons directly at the human brainstem, bypassing the inner ear entirely.</span></p> <p><span style="font-size: 10pt;"><br />The young children who had ABIs implanted outside the United States now have the potential to understand speech, but, in the United States, the device is FDA-approved for use only in patients 12 years or older with neurofibromatosis type II, an inherited disease that causes a non-malignant brain tumour on the hearing nerve. It has shown limited effectiveness in adults, however, and scientists believe that the device would be more effective in young children, when their brains are more adaptable. The clinical trial will attempt to prove that this surgery is safe in young children and allow researchers to study how the brain develops over time and how it learns to hear sound and develop speech.</span></p> <p><span style="font-size: 10pt;"><br />&ldquo;The children in this study are under five years of age,&rdquo; says Keck School of Medicine of USC Professor Robert V Shannon, an investigator for the trial and leading scientist in the development of ABI technology since 1989. &ldquo;When a child is born, their ear is hard-wired for sound but the brain has to learn how to perceive sound and speech from the information coming up the hearing pathway. If the ear is not providing sound information to the brain, the hearing part of the brain does not develop properly. The ABI provides sound to these pathways so they grow and develop with the child.&rdquo;</span></p> <p><span style="font-size: 10pt;"><br />After the devices are implanted, the Los Angeles-based researchers will study how the brain develops over time as it incorporates sound and speech. If the clinical trial is successful, children across the United States will be able to benefit from surgical and audiology techniques and safety and efficacy protocols developed in the study.</span></p></div> Medtronic completes acquisition of Visualase http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/medtronic-completes-acquisition-of-visualase 2014-07-28T14:54:00Z 2014-07-28T14:54:00Z <div id="Introduction77" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Medtronic has announced that it has completed the acquisition of Visualase, a&nbsp;privately held company based in Houston, USA, that develops and markets an FDA-approved MRI-guided laser and image guided system for minimally invasive neurosurgeries, including surgical thermal ablation.</strong></span></p> </div><div id="Text177" style="clear:both; text-align:left"><p><span style="font-size: 10pt;">Medtronic will add Visualase&rsquo;s MRI-guided laser ablation system to its portfolio of therapies for treating neurological conditions within its Surgical Technologies business and will integrate the technology into its broader neuroscience offerings.

NeuroPace received premarket approval (PMA) from the US Food and Drug Administration (FDA) for the RNS System in November 2013. It is approved as a treatment for adults with partial onset seizures with one or two seizure onset zones whose seizures have not been controlled with two or more antiepileptic drugs.</span></p> <p><br /><span style="font-size: 10pt;">Through the DARPA RAM research, NeuroPace and other collaborators will gain fundamental knowledge regarding the restoration of memory. The company believes this research may expand the clinical applications of the RNS system beyond the treatment of epilepsy, as well as provide the understanding necessary to inform the development of future devices that expand the capabilities of responsive neurostimulation. This collaborative effort will advance the field of brain research and closed-loop neurostimulation applications. A portion of the DARPA project will involve epilepsy patients implanted with the RNS system at seven Comprehensive Epilepsy Centers and will be led by Barbara Jobst, professor of Neurology at Dartmouth, and Martha Morrell, chief medical officer at NeuroPace and clinical professor of Neurology at Stanford University. A separate part of the project will begin with epilepsy patients implanted with the RNS system at UCLA with Itzhak Fried serving as the principal investigator.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;Using the RNS system, we will be able to immediately explore ways in which brain stimulation can restore memory function in patients with epilepsy. Insights derived from these early studies will help to guide future research in patients with other neurological disorders that result in memory loss,&rdquo; says Michael Kahana, principal investigator at the University of Pennsylvania.</span></p> <p><br /><span style="font-size: 10pt;">As a closed-loop system, the RNS system monitors the brain&rsquo;s own signals, interprets those signals, provides stimulation when needed, and then assesses the brain&rsquo;s response. The breakthrough aspect of the RNS system is its advanced detection and stimulation capabilities. This is unlike all other existing neurostimulation therapies, which continuously or intermittently stimulate the brain without determining the need for treatment or monitoring the response.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;The RNS system is the only commercially available product that continuously monitors the brain&rsquo;s electrical signals, delivers stimulation only when needed and then monitors the response,&rdquo; says Frank Fischer, chief executive officer at NeuroPace. &ldquo;This capability is critical to the research phase of projects like the DARPA RAM programme.

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="ImageMain83" 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="Introduction83" 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="Text183" 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> 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="ImageMain84" 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="Introduction84" 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="Text184" 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.

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="Text187" 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’s Institute partners with Novartis in new study of Alzheimer’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="Introduction88" 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="Text188" 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’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="ImageMain89" 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="Introduction89" 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="Text189" 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="ImageMain90" 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="Introduction90" 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="Text190" 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="Introduction91" 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="Text191" 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="Introduction94" 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="Text194" 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="Introduction95" 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="Text195" 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="Introduction96" 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="Text196" 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.

Their earlier phase I trial of eTNS for the treatment of ADHD, funded by NeuroSigma, found significant improvements in the severity of ADHD symptoms with eight weeks of nightly eTNS therapy.&nbsp;This phase II clinical trial will evaluate eTNS as monotherapy, under double-blind conditions, in up to 90 children, ages eight to 12, in a four week randomised clinical trial conducted at UCLA.&nbsp;NeuroSigma will provide eTNS systems to&nbsp;UCLA&nbsp;in support of the trial.&nbsp;Neither McGough nor Loo has any affiliation with NeuroSigma.</span></p> <p><span style="font-size: 10pt;"><br />ADHD usually arises in childhood.&nbsp;The US Center for Disease Control and Prevention (CDC) has reported national survey findings that approximately 11% of children ages four to 17 have been diagnosed with the disorder, and that about one in five high school boys will receive this diagnosis during childhood.&nbsp;Symptoms include difficulty paying attention in school, at play, or in the home, a reluctance to take on tasks that require sustained mental effort, being easily distracted, exhibiting physical hyperactivity, and engaging in impulsive behaviours.&nbsp;These symptoms may interfere with social, school, or work functioning.</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;I am very pleased that the NIH has funded this extremely important phase II clinical trial in ADHD.&nbsp;Millions of parents seek alternatives to drug treatment for their children with ADHD that are safe and non-invasive,&rdquo; says Leon Ekchian, NeuroSigma&rsquo;s president and chief executive officer.&nbsp;</span></p> <p><br /><span style="font-size: 10pt;">&ldquo;McGough and Loo are to be congratulated for receiving this grant, particularly at a time when the NIH budget is under pressure to fund only the most promising lines of investigation. NIH awards represent one of the most stringent forms of peer review in biomedical science,&rdquo; notes&nbsp;Ian Cook, NeuroSigma&rsquo;s chief medical officer and senior vice president.&nbsp;&ldquo;Besides showing safety of eTNS in children, their phase I study found a significant impact on the clinical symptoms of ADHD, and substantial improvements on sleep as well as several objective computer-based measures of cognitive performance.&nbsp;We look forward to confirming these results in this phase II clinical trial under double-blind controlled conditions. A neuromodulation treatment option for ADHD could avoid concerns about the exposure of children to the psychostimulant medications that are the current first-line treatments.&rdquo;&nbsp;</span></p></div> New US patent for Barrel vascular reconstruction device http://www.cxvascular.com/nn-latest-news/neuro-news---latest-news/new-us-patent-for-barrel-vascular-reconstruction-device 2014-07-11T15:32:00Z 2014-07-11T15:32:00Z <div id="Introduction100" style="clear:both;"> <p><span style="font-size: 11pt;"><strong>Reverse Medical Corporation has announced that the United States Patent Office has notified the company that a new patent has issued entitled &ldquo;Protuberant Aneurysm Bridging Device and Method of Use&rdquo;.
