MedicalResearch.com Interview with: Regina BlyeChief Program and Policy Officer Discusses the  Living with Paralysis & Caregiver National Survey Conducted by the Christopher and Dana Reeve Foundation MedicalResearch.com: How large is the population of Americans living with paralysis Response:  There is a significant population of Americans living with paralysis. To note, a 2013 study by the Christopher & Dana Reeve Foundation found that 1 in 50 people in the US are living with paralysis. This is approximately 5.4 million people. I, myself, have lived with a spinal cord injury (SCI) for over 35 years. While some progress has been made over the past few decades, there is still work to be done. In a new survey conducted by the Christopher & Dana Reeve Foundation called “Living with Paralysis & Caregiver National Survey,” we learned that a majority of Americans (69%) underestimate the prevalence of those living with paralysis in the U.S. - about two out of every 100 individuals. Given the notable size of the population, we must work together to educate and inform families, business leaders, advocates, policymakers and the general public to help improve the quality of life for those living with, or impacted by paralysis. The Christopher & Dana Reeve Foundation is dedicated to curing spinal cord injury by advancing innovative research and improving the quality of life for individuals and families impacted by paralysis. While we’ve been fortunate to make advancements with significant support from the community, we must all unite to accelerate comprehensive information, resources, referral services, and innovative research together.

What are the main findings? Response: We are publishing the results of two successful phase 3 trials in relapsing MS (multiple sclerosis). We tested a glycoengineered antibody to B cells. The glycoengineered antibody are more potent in killing the target. They can be delivered more easily. (more…)
Author Interviews, Brigham & Women's - Harvard, Neurology, Parkinson's / 21.06.2022

MedicalResearch.com Interview with: Vikram Khurana, MD, PhD Chief of the Division of Movement Disorders Department of Neurology Brigham and Harvard Medical School Principal investigator, Ann Romney Center for Neurologic Diseases at the Brigham MedicalResearch.com:  What is the background for this study?   Response: Proteins abnormally accumulate in brain cells (neurons and glial cells) in all neurodegenerative diseases. In Parkinson’s disease and related disorders, the key protein that accumulates and aggregates is called “alpha-synuclein.” Presumably, when a protein like alpha-synuclein abnormally folds and aggregates, the abnormal form of the protein can become toxic to the neuron, eventually leading to cell death. Equally, the protein may no longer be able to carry out its normal function. This begs the question – what does alpha synuclein actually do? Most evidence to date points to alpha-synuclein being involved in the transport of other proteins and chemicals around the cell, by closely associating with vesicles that are small circular containers enclosed by fat (“lipid) membranes. But alpha-synuclein is not just found associated with these vesicle membrane. It is found away from the membrane and it’s been unclear what it does there. (more…)

MedicalResearch.com Interview with: Juan Piantino, M.D., MCR Assistant Professor of Pediatrics Division of Neurology, School of Medicine Director, Inpatient Child Neurology Oregon Health Sciences University  MedicalResearch.com:  What is the background for this study?    Response: Astronauts are exposed to several stressors during spaceflight, including radiation, lack of gravity, and sleep deprivation. The effects of those stressors on the brain remain unknown. Is it safe to travel to space? For how long can humans survive in space? What are the effects of spending months under zero gravity? With more extended missions, and an increased number of civilians traveling to space, there is increased interest in understanding what happens to our brains when we leave earth. (more…)

MedicalResearch.com Interview with: William R. Renthal, MD, PhD Director of Research, John R. Graham Headache Center Department of Neurology Brigham and Women's Hospital Assistant Professor of Neurology, Harvard Medical School MedicalResearch.com:  What is the background for this study?  Response: We know that a nervous system structure called the trigeminal ganglion plays a critical role in migraine headache, but the cell types that exist in this structure are poorly understood. We have used cutting-edge, single-cell genomic technologies to profile the genes expressed within each trigeminal ganglion cell type in both human and mouse with the goal of identifying molecular features that could allow us to inhibit head pain selectively without affecting other cell types.

Author Interviews, Cannabis, Neurology, Pediatrics / 15.12.2021

MedicalResearch.com Interview with: Rayyan Raja Zafar BSc. MSc. MRSB. Medical Research Council Doctoral Training Partnership (MRC DTP) PhD Candidate Centre for Psychedelic research & Neuropsychopharmacology Division of Psychiatry Department of Brain Sciences, Faculty of Medicine Professor David Nutt DM, FRCP, FRCPsych, FSB, FMedSci Faculty of Medicine, Department of Brain Sciences The Edmond J Safra Chair in Neuropsychopharmacology Imperial College London MedicalResearch.com: What is the background for this study? Response: Since 2018 medical cannabis prescription has become legal in the UK for patients to access. In spite of this legal change less than 3 NHS prescriptions have been made available and access to whole-plant medical cannabis products has been restricted largely to private prescriptions with very few clinicians prescribing such products. There has been a lot of anecdotal and real world evidence of the value of whole-plant medical cannabis in children suffering with treatment resistant epilepsy. (more…)
Author Interviews, Brain Injury, Neurology / 11.10.2021

Dr. Mahncke earned his PhD at UCSF in the lab where lifelong brain plasticity was discovered. At the request of his academic mentor, he currently leads a global team of more than 400 brain scientists engaged in designing, testing, refining, and validating the computerized brain exercises found in the BrainHQ app from Posit Science, where he serves as CEO. Earlier this year, MedicalResearch.com interviewed Dr. Henry Mahncke about the BRAVE Study he led, which showed a digital health app (BrainHQ) was effective in addressing chronic cognitive issues in servicemembers who had been diagnosed with “mild” Traumatic Brain Injury. This week, MedicalResearch.com interviews Dr. Mahncke again about a new independent study among civilians showing similar results in patients with all kinds of Brain Injuries. MedicalResearch.com: What is the background for this study? Response: The Centers for Disease Control (CDC) estimates that about 5.3 million people currently live with a chronic disability from a Traumatic Brain Injury (TBI). While most people who suffer a blow to the head recover in a couple days or weeks, for some (estimated as high as 15 percent) the injury persists with a variety of life-disrupting symptoms, including impairments in cognitive abilities, behavior, emotions, and motor function affecting work, relationships, and daily function. TBIs have been the signature injury of recent wars. Nearly 400,000 service members have been diagnosed with TBIs, of which 82% were diagnosed with so-called “mild” TBIs from concussions and blast injuries. More than a decade ago, we began being asked by military and Veterans organizations, to study whether our brain exercises – which had shown positive effects in measures of cognition, everyday function, mood, and motor function in healthy older adults – could have an impact on people with chronic symptoms from TBIs. We talked earlier this year, when an 83-person, gold-standard, randomized controlled trial on mTBI (called the BRAVE Study) announced quite positive results from using BrainHQ exercises. That study was funded by the Department of Defense and run as five military and Veterans medical centers. The BRAVE Study found the BrainHQ group showed a statistically and clinically significant improvement on a standard measure of overall cognitive function (compared to a computer games control), and this benefit persisted for at least 12 weeks after training completed. Cognitive function improvements were nearly four times larger in the BrainHQ group than the control (as measured immediately following training) and grew to nearly five times larger (when measured again 12 weeks after training ended). On average, participants in the BrainHQ group improved on the cognitive performance composite measure by 24 percentile ranks – as though they went from the 50th percentile to the 74th percentile. One large question left unanswered from the BRAVE study was whether this approach might also work for other categories of TBIs, such as moderate and severe TBIs. A new study from independent researchers at NYU answers that question. (more…)

MedicalResearch.com Interview with: Jessica Ailani M.D. FAHS FAAN FANA Director Medstar Georgetown Headache Center Vice Co-Chair of Strategic Planning for MedStar Neurology Professor of Clinical Neurology MedStar Georgetown University Hospital MedicalResearch.com: What is the background for this study? Response: Migraine is a common neurological disease that causes disabling attacks that can be frequent. Preventive treatments can help reduce the frequency of attacks and improve patient function, reducing disease burden. (more…)
Author Interviews, JAMA, Neurology / 24.12.2020

MedicalResearch.com Interview with: Dr. Roopa Rajan MD, DM Post Doctoral Fellowship (Movement Disorders) Assistant Professor Department of Neurology AIl India Institute of Medical Sciences New Delhi  MedicalResearch.com: What is the background for this study? Response: This study was inspired by the need for more effective treatments for patients with disabling hand tremor, particularly dystonic tremor. Dystonic tremor is a movement disorder in which both dystonia (abnormal posturing) and tremor co-exist in the same body part. In general, this common and often disabling disease responds only modestly to oral medications. Surgical treatments such as deep brain stimulation may be offered to persons with severe tremor, however the outcomes are not as robust as seen in other tremor conditions,  for instance, essential tremor. Therefore, there is a critical need for more effective treatments for people living with this disease. Botulinum toxin injections are known to be effective for dystonic tremor affecting the head and voice, although these remain off-label indications. Previous studies using botulinum toxin injections for other hand tremors like essential tremor led to limited clinical application, in part due to transient hand weakness that may be a side effect of botulinum toxin injections. Recently, advances in injection delivery such as electromyographically guided botulinum toxin injections with individualized muscle and dose selections were reported to be beneficial in essential tremor. We built upon this existing data to explore the effects of such a treatment in patients with dystonic hand tremor.   (more…)
Author Interviews, Diabetes, Neurology, Pain Research / 10.12.2020

MedicalResearch.com Interview with: William K. Schmidt, Ph.D. Senior VP Clinical Development Helixmith Co. Ltd.  MedicalResearch.com: What is the background for this study? How common is diabetic peripheral neuropathy and how does it affect patients? Response: According to the Centers for Disease Control and Prevention (CDC), over 34 million people in the United States have diabetes (about 10% of the U.S. population) and about one in four patients do not know that they have it (https://www.cdc.gov/chronicdisease/resources/publications/factsheets/diabetes-prediabetes.htm).  Diabetes can cause significant damage to nerves in the feet, hands, eyes, and other parts of the body. Diabetic peripheral neuropathy (DPN) is the most common form of nerve damage worldwide; it affects approximately half of the patients with diabetes (Iqbal et al., 2018).  In many individuals, severe burning, tingling, “pins and needles,” or cramping pain can occur simultaneously in both feet without external evidence of foot damage. Despite the pain, symptoms may be accompanied by numbness or loss of sensation in the feet. This is called painful diabetic peripheral neuropathy (painful DPN or P-DPN) and may affect up to one-third of the general diabetic population (Yoo et al., 2013). P-DPN may cause increased anxiety and depression, sleep impairment, and difficulties with walking.  Up to one-third of P-DPN patients may require the use of a cane, walker, or even a wheelchair due to extreme foot pain.  Once P-DPN occurs, it may result in a lifetime of pain and disability. FDA-approved daily oral medications often used to treat P-DPN include Neurontin (gabapentin), Lyrica (pregabalin), Cymbalta (duloxetine), and Nucynta ER (tapentadol).  While these “neuropathic pain” medications may dull the pain for some subjects, they produce significant side effects that may be troubling for many patients. Indeed, many patients stop using these pain killers due to lack of effectiveness at doses that they can tolerate (van Nooten et al., 2017) There is also a topical 8% capsaicin patch, but again with limited efficacy. It is well known that the most severely affected patients may require opioid analgesics to control P-DPN (Pesa et al., 2013). None of the currently used medications have disease-modifying effects. However, our new injectable medication is now in advanced clinical development that has the potential disease-modifying effects lasting months after each treatment, with limited or no side effects for most patients aside from brief injection site discomfort.

MedicalResearch.com Interview with:
BrainHQHenry Mahncke, PhD
Chief Executive Officer BrainHQ
Dr. Mahncke earned his PhD at UCSF in the lab where lifelong brain plasticity was discovered. At the request of his academic mentor, he currently leads a global team of more than 400 brain scientists engaged in designing, testing, refining, and validating the computerized brain exercises found in the BrainHQ app from Posit Science, where he serves as CEO.
MedicalResearch.com Tell us what’s important about this new study in people with Down Syndrome? Response: Often, we believe that genetic conditions are predetermined and completely inalterable, but this new study underscores that, when it comes to the brain, positive change is almost always possible – regardless of age or health condition. That’s consistent with the science of brain plasticity, and it’s a very different and hopeful way to think about the potential of people with Down Syndrome – and people, generally.   MedicalResearch.com: Can you briefly describe Down Syndrome and findings in this study? Response: Down Syndrome is one of the most common genetic abnormalities in humans, found in about 1 in 1,000 births each year, and caused by the presence of all or part of a third copy . of chromosome 21.It’s usually associated with physical growth delays and characteristic facial features. While cognitive abilities vary enormously, one study estimates the average IQ of a young adults is about 50 (comparable to average 8 or 9 year olds). In a pilot study among 12 people with Down Syndrome involving physical, cognitive and EEG measurements, researchers at Aristotle University of Thessaloniki, Greece, found a 10-week combined protocol of physical exercises and computerized brain training led to a reorganization of the brain and to improved performance on both cognitive and physical measures. The physical training consisted of aerobic, flexibility, strength, and balance exercises. The cognitive training used in the study was the Greek version of the commercially-available BrainHQ brain app, consisting of 29 visual and auditory exercises targeting memory, attention, processing speed, problem-solving, navigation, and social skills. The researchers had hypothesized that the training would trigger the brain’s neuroplasticity – its ability to change chemically, structurally and functionally. Their results showed increased connectivity within the left hemisphere and from left to right hemisphere, as well as improved performance on physical and cognitive assessments.   (more…)
Alzheimer's - Dementia, Author Interviews, Blood Pressure - Hypertension, Neurology, UCSF / 10.08.2020

MedicalResearch.com Interview with: Laure Rouch, PharmD PhD Department of Psychiatry Dr. Kristine Yaffe, MD (Senior Author) Departments of Psychiatry, Neurology, and Epidemiology University of California San Francisco, San Francisco VA Medical Center, San Francisco, CA, USA MedicalResearch.com: What is the background for this study? Response: Worldwide, around 50 million people have dementia and this number is set to triple by 2050. Prevention of dementia and identification of potentially modifiable risk factors are, therefore, critically important. Postural changes in blood pressure increase with advancing age and affect 20% to 30% of older adults. Yet it has not been explored deeply how orthostatic hypotension and blood pressure postural changes variability over time are associated with dementia risk. As multiple pharmacologic and nonpharmacologic interventions may improve orthostatic symptoms, this question has major public health implications. (more…)

MedicalResearch.com Interview with: Darren Schreiber JD PhD Senior Lecturer Exeter MedicalResearch.com: What is the background for this study? Response: My co-authors and I saw an opportunity to match existing functional brain imaging data with publicly available voter registration data so that we could look for patterns that distinguish brain activity in nonpartisans from partisans.  While a number of studies have found differences in both brain structure and function between partisans on the left and right and there is a massive amount of scholarship in political science on partisans and polarization, no brain imaging work had focused on nonpartisans. Around 40% of Americans do not affiliate with a political party and one important campaign strategy has been to persuade these voters to support party candidates.  However many political scientists are skeptical about voters claims to be nonpartisans and will instead treat them as if they were merely covert partisans.

Author Interviews, Neurology, Parkinson's / 22.06.2020

MedicalResearch.com Interview with: Stewart A. Factor, D.O. Professor of Neurology Director of the Movement Disorders Program Vance Lanier Chair of Neurology Emory University School of Medicine MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by OFF episodes.  Response: Parkinson’s disease (PD) is a chronic, progressive neurodegenerative disease characterized by motor symptoms, including tremor at rest, rigidity and impaired movement, as well as significant non-motor symptoms, such as cognitive impairment, psychiatric symptoms and autonomic symptoms (i.e. urinary issues, constipation, low blood pressure). It is the second-most common neurodegenerative disease after Alzheimer’s disease and it is predicted that the prevalence of Parkinson’s disease will double by the year 2040. The symptoms of PD are in substantial part, due to loss of dopamine nerve cells in the brain. The current standard of care for PD includes replacing the dopamine loss by the use of oral carbidopa/levodopa. Levodopa is a precursor of dopamine, converted in the brain. OFF episodes have been a significant unmet need in Parkinson’s disease since the emergence of levodopa. Initially, levodopa controls PD symptoms in a continuous fashion throughout the day. With time the response becomes less predictable and patients experience a re-emergence or worsening of PD symptoms. These episodes are what we mean by OFF episodes. OFF episodes can be characterized, in part, by re-emergence of motor symptoms including tremor, stiffness or slowed movement that can happen at any point during the day. OFF episodes typically begin within the first five years of treatment and occur at the end of a dose. This is referred to as end of dose failure or wearing off. Within the first four to six years after diagnosis, regardless of disease severity, up to 60 percent of people with PD experience OFF episodes. With time these episodes become longer, more severe and disabling, more frequent and less predictable as PD progresses. They can take up more than half the day OFF episodes may alter a persons’ ability to perform everyday activities by slowing or even precluding their completion. The result is significant burden and distress for people living with Parkinson’s disease (PD) and their care partners. CTH-300 was a Phase 3, 12-week, randomized, double-blind, placebo-controlled, parallel group, study examining the efficacy, safety and tolerability of apomorphine hydrochloride sublingual film (KYNMOBI) in people with levodopa-responsive PD complicated by OFF episodes. The primary endpoint was a mean change in the score from pre-dose in the Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) Part III Motor Examination at 30 minutes after dosing at the 12-week visit of the maintenance treatment phase. The key secondary endpoint was the percentage of people with PD with a patient-rated full ON (or best) response within 30 minutes at the 12-week visit of the maintenance treatment phase.

Author Interviews, JAMA, Multiple Sclerosis, Neurology / 15.06.2020

MedicalResearch.com Interview with: Cris S Constantinescu,  MD, PhD, FRCP Professor, Division of Clinical Neuroscience Research Group in Clinical Neurology University of Nottingham Queen's Medical Centre Nottingham UK MedicalResearch.com: What is the background for this study? Response: The study is in some way a test of the hygiene or old friends hypothesis, whereby eradication, through improved hygiene, of some parasites that have existed in the human gut for thousands of years and have suppressed inflammatory reactions, leads to an increase in inflammatory conditions. This has been used to explain the increased autoimmune and inflammatory diseases in the developed world. Healthy volunteer studies at the University of Nottingham showed therapeutic hookworm infection to be safe and well tolerated up to about 50 larvae, and then safety studies in people with airway hyperreactivity and inflammatory bowel disease raised no concern. Following a study in Argentina showing that people with MS have milder disease when they have a natural co-existing asymptomatic infection with intestinal parasites, we (Professor Pritchard, immunoparasitologist and myself) decided to test hookworm in MS, and for the first time used 25 larvae in a patient study.

MedicalResearch.com Interview with: Holly Yancy, DO Headache medicine specialist Banner – University Medicine Neuroscience Institute Phoenix, AZ Dr. Yancy comments on the recent Neurology journal article on the potential impact of yoga on migraine.  MedicalResearch.com: What is the background for this study? How might yoga reduce migraine intensity or frequency?  Response: The authors of this trial have studied the benefits of yoga when added to medical management of episodic migraine. They expand on prior, smaller reports of the potential benefit of yoga and mindfulness to migraine patients with a well-designed study that shows yoga, as an adjunct to preventive medication, can lower the intensity, frequency and impact of migraines. Participants even used less abortive medication. The authors propose multiple potential mechanisms of action, including an increase in parasympathetic / decrease in sympathetic nervous system activity, decreased muscle tension, and stress management.

Author Interviews, Dermatology, Neurology / 28.04.2020

MedicalResearch.com Interview with: Santosh K. Mishra M.Tech., PhD Assistant Professor of Neuroscience Department of Molecular Biomedical Sciences NC State Veterinary Medicine Raleigh, NC 2760 MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by atopic dermatitis? Response: Chronic allergic itch is a worldwide problem that leads to substantial health expenses,but what causes this universal urge to scratch remains elusive in chronic allergic itch. Atopic dermatitis is a common allergic skin disease that often associated with extremely itchy and inflamed skin. In our study, we showed, for the first time, a molecular pathway that is involved in chronic allergic itch as we identified an endogenous mediator (periostin) and a new role for its sensory neuron receptor, the integrin αVβ3, which drives the excitability and transmission of itch signal to the spinal cord.  (more…)
Author Interviews, Neurology, Pain Research / 12.02.2020

MedicalResearch.com Interview with: Chun Yuen Fong Post-doc research fellow Center for Cognitive and Evolutionary Science University of Tokyo  MedicalResearch.com: What is the background for this study? Response: Migraine is one of the most prevalent neurological disorders worldwide. However, what exactly trigger a migraine episode is not entirely clear despite years of research. Moreover, migraine sufferers often report having excessive sensitivity to light and certain patterns during the headache-free period. Some researchers suggested that such abnormal sensations were associated with the enhanced cortical hyperexcitability of the migraine sufferers. In our study, we aimed to build on this theory by comparing the neurophysiological activities between regular migraine sufferers and control using electroencephalography (EEG). Using the same research method, we also compared the neural activities between healthy participants who reported having more abnormal visual sensations to those with less. (more…)
Alzheimer's - Dementia, Author Interviews, Cognitive Issues, McGill, Neurology, Technology / 28.01.2020

MedicalResearch.com Interview with: Yasser Iturria-Medina PhD Assistant Professor, Department of Neurology and Neurosurgery Associate member of the Ludmer Centre for Neuroinformatics and Mental Health McConnell Brain Imaging Centre McGill University MedicalResearch.com: What is the background for this study? Response: As background, two main points:
  • Almost all molecular (gene expression) analyses performed in neurodegeneration are based on snapshots data, taking at one or a few time points covering the disease's large evolution. Because neurodegenerative diseases take decades to develop, until now we didn't have a dynamical characterization of these diseases. Our study tries to overcome such limitation, proposing a data-driven methodology to study long term dynamical changes associated to disease.
Also, we still lacked robust minimally invasive and low-cost biomarkers of individual neuropathological progression. Our method is able to offer both in-vivo and post-mortem disease staging highly predictive of neuropathological and clinical alterations. (more…)
Author Interviews, Education, Gender Differences, Neurology, UC Davis / 27.01.2020

MedicalResearch.com Interview with: Allison Brashear, M.D., M.B.A. Dean, UC Davis School of Medicine MedicalResearch.com: What is the background for this study? Why is the demand for neurology services and neurologists increasing?  Response: The American Academy of Neurology estimates that by 2025 the number of neurologists in practice will increase to 18,060 but some 3,400 more will be needed to meet the demand for their services. The 58% increase in the number of residency positions in the National Resident Matching Program since 2008 also reflects the growing demand. The higher prevalence of neurologic conditions, aging U.S. population and more patients having access to the health care coverage are the major driving forces. (Note: source of NRMP neurology trend data comes from a physician/resident forum posted May 2019 https://forums.studentdoctor.net/threads/growth-trends-in-neurology-residency-positions.1375918/) MedicalResearch.com: Why is neurology included among the less desirable fields of medicine (similar to nephrology, infectious disease, endocrinology etc.) for medical students and residents to pursue?  Why is burnout and dissatisfaction so high? Response: According to the American Academy of Neurology, a minority of medical students choose to train in neurology each year, with approximately 3.1% matching into a neurology residency in 2018. The newer generations of neurologists value lifestyle and time off work more than their predecessors. According to a recent American Medical Association survey, neurology tied with critical care as the medical specialty with the highest stress levels and burnout. Too many administrative tasks, too many hours at work, increased computerization of practice and insufficient compensation were among the top causes of burnout. (more…)
Author Interviews, Cost of Health Care, Emergency Care, Neurology / 10.01.2020

MedicalResearch.com Interview with: Simon Borghs MSc RWE Strategy Lead of Neurology UCB:  Union Chimique Belge MedicalResearch.com: What is the background for this study? Response: Epilepsy is an episodic disease and so is associated with a more or less unpredictable occurrence of health care encounters. These encounters are costly and so reducing them, or their unpredictability, could be cost saving. The objective was to assess one half of this equation, that is the actual cost of those encounters to insurers. This could prompt insurers to consider addressing possible interventions in epilepsy to reduce the number of encounters (more…)

We have created an artificial intelligence clinical decision support tool based on brain volumetric and PET metabolic activity measurements as well as other clinical measurements. (more…)
Author Interviews, Autism, Neurology / 11.12.2019

MedicalResearch.com Interview with: Dr. Neil Dawson PhD Senior Lecturer Lancaster University MedicalResearch.com: What is the background for this study? Response: Deletions on chromosome 2p16.3, involving deletion of the NEUREXIN1 gene, dramatically increase the risk of developing a wide range of neurodevelopmental disorders including autism, Tourette’s syndrome and schizophrenia. We don’t fully understand the mechanisms involved. In our study we wanted to understand how the genetic deletion impacts on brain function and the ability of brain regions to communicate with one another, as these are known to be impaired in these neurodevelopmental disorders. We also wanted to determine how the genetic deletion impacts on the function of neurotransmitter systems involved in these disorders, and whether drugs targeting these neurotransmitter systems could restore some of the deficits in brain function seen.

MedicalResearch.com Interview with: Priv.-Doz. Dr. med. Christoph Schankin Consultant Head University Headache Clinic Department of Neurology Inselspital, Bern University Hospital University of Bern MedicalResearch.com: What is the background for this study? Response: Visual snow syndrome is a debilitating disorder with a continuous TV snow-like visual disturbance that persists over years. Patients have additional visual problems, such as severe afterimages, floaters or photophobia. The syndrome is associated with migraine and migraine aura, but the interaction between the two remains unclear. (more…)
Alzheimer's - Dementia, Author Interviews, Cognitive Issues, Duke, Neurology / 24.09.2019

MedicalResearch.com Interview with: Juan Helen Zhou, PhD, on behalf of the co-authors Associate Professor and Principal Investigator Neuroscience and Behavioural Disorders (NBD) Programme Duke-NUS Medical School, SingaporeJuan Helen Zhou, PhD, on behalf of the co-authors Associate Professor and Principal Investigator Neuroscience and Behavioural Disorders (NBD) Programme Duke-NUS Medical School, Singapore  MedicalResearch.com: What is the background for this study? Response: Alzheimer’s disease and cerebrovascular disease are among the leading disorders affecting the elderly, with up to 50 per cent of dementia patients showing co-occurrence of both disorders. It is therefore of great interest to understand the influence of co-occurring Alzheimer’s disease and cerebrovascular disease pathologies on brain changes, and examine if such changes are able to track early differential disease progression. Past cross-sectional studies have suggested that Alzheimer's disease and cerebrovascular disease pathologies contribute independently to brain functional and structural changes, and cognitive decline. Our study sought to demonstrate the independent contributions of both pathologies to brain functional networks in a longitudinal cohort of mild cognitive impairment patients, often regarded as early stage of the disease.

Author Interviews, Lancet, Neurology, Surgical Research / 05.07.2019

MedicalResearch.com Interview with: Dr. Natasha van Zyl, MBChB (Cape Town), FRACS FRACS Plastic and Reconstructive Surgeon Melbourne, Australia  MedicalResearch.com: What is the background for this study? What are the main findings? Response: The estimated global incidence of spinal cord injury (SCI) from all causes is 40 to 80 new cases per million population per year which means that every year between 250 000 to 500 000 people worldwide suffer SCI (1)(chap 2 p 17). In Australia the age standardised, annual incident rate of persisting traumatic SCI for Australian residents aged 15 years and above is 11.8 cases per million.(2) Just over 50% of all spinal cord injuries  in Australia occur at the cervical level resulting in tetraplegia. (2) Cervical spinal cord injury is a devastating, life-changing injury impacting almost every aspect of a person’s work, family and social life. Although compared to many other health conditions it has a relatively low incidence, it is certainly a high cost health condition, with the lifetime cost per tetraplegia incident case estimated to be AU$9.5 million.(3) For those living with tetraplegia improvement in hand function is their highest ranked goal.(4) As such, reconstruction of upper extremity function in cervical spinal cord injury is a crucial component of the surgical rehabilitation of people with mid/low cervical spinal cord injury as it has the capacity to restore critical functions such as elbow extension, wrist extension, grasp, key pinch and release. Traditionally these functions have been reconstructed using tendon transfers, which move a functioning muscle to a new insertion site to recreate the function of a paralysed muscle.(5) (more…)
Author Interviews, Brain Injury, Columbia, Critical Care - Intensive Care - ICUs, NEJM, Neurology / 27.06.2019

MedicalResearch.com Interview with: Jan Claassen, MD, PhD, FNCS Associate Professor of Neurology Division of Division of Critical Care and Hospitalist Neurology Columbia University Medical Center MedicalResearch.com: What is the background for this study? What are the main findings? Response: Unconsciousness is common and predicting recovery is challenging – often inaccurate. Many patients do not show movements on commands and typically this is interpreted as unconsciousness. Some of these patients may be able to have brain response to these commands raising the possibility of some preservation of consciousness. This has previously been shown months or years after the injury mostly using MRI. We were able to detect this activation at the bedside in the ICU shortly after brain injury. For this we applied machine learning to the EEG to distinguish the brain’s responses to commands. Patients that showed this activation were more likely to follow commands prior to discharge and had better outcomes one year later.  (more…)
