A recent study led by Assistant Professor Feng Lei from the National University of Singapore (NUS) Yong Loo Lin School of Medicine’s Department of Psychological Medicine revealed that regular tea drinkers have better organised brain regions – and this is associated with healthy cognitive function – compared to non-tea drinkers. The research team made this discovery after examining…
A person with drug resistant epilepsy who gets an early surgical intervention has a better chance of becoming seizure free. This is shown in a systematic review and meta-analysis in which Sahlgrenska Academy researchers, in collaboration with the Swedish Council for Assessment of Health Technology and Social Services (SBU), analysed results from a range of previous studies. They concluded that…
More and more people aged 50 and over are suffering from age-related vision disorders. According to the World Health Organization, in four out of five cases they could be avoided if they were diagnosed at an early stage. A European team of scientists, including the Leibniz Institute of Photonic Technology (Leibniz IPHT) in Jena, has now researched a new method that will enable doctors to better…
The recording of images of the human brain and its therapy in neurodegenerative diseases is still a major challenge in current medical research. The blood-brain barrier, a filter system of the body between the blood system and the central nervous system, constrains the supply of drugs or contrast media that would allow therapy and image acquisition.
A novel neck brace, which supports the neck during its natural motion, was designed by Columbia engineers. This is the first device shown to dramatically assist patients suffering from Amyotrophic Lateral Sclerosis (ALS) in holding their heads and actively supporting them during range of motion. This advance would result in improved quality of life for patients, not only in improving eye contact…
Neurons of the central nervous system (CNS) shut down their ability to grow when they no longer need it; this is commonly accepted knowledge. This occurs normally after they have found their target cells and established synapses. However, recent findings show that old nerve cells have the potential to regrow and to repair damage similar to young neurons. The underlying mechanisms for this…
In a new study, led by the University of Glasgow, scientists show that brain activity recorded using functional magnetic resonance imaging (fMRI) may help predict response to CBT in depression before the treatment commences. The advances could help patients receive the most appropriate treatment for depression in a timely manner.
Scientists have identified mechanisms in the human brain that could help explain the phenomenon of the 'Uncanny Valley' - the unsettling feeling we get from robots and virtual agents that are too human-like. They have also shown that some people respond more adversely to human-like agents than others.
New results of a 65-year follow-up study of nearly 7,000 Norwegian patients with Multiple Sclerosis (MS) suggest that patients may have a greater overall risk of developing cancer than the general population, with an especially high risk of cancer in respiratory organs, urinary organs and the central nervous system. Presented at the 5th European Academy of Neurology (EAN) Congress in Oslo,…
Doctors could soon get some help from an artificial intelligence tool when diagnosing brain aneurysms—bulges in blood vessels in the brain that can leak or burst open, potentially leading to stroke, brain damage or death.
Professor Marco Catani suggests the best explanation for Leonardo da Vinci's inability to finish his works is that the great artist may have had Attention Deficit and Hyperactivity Disorder. Leonardo da Vinci produced some of the world’s most iconic art, but historical accounts of his work practices and behaviour show that he struggled to complete projects. Drawing on these accounts, Professor…
Neonatal exposure to nicotine alters the reward circuity in the brains of newborn mice, increasing their preference for the drug in later adulthood, report researchers at University of California San Diego School of Medicine in a study published in Biological Psychiatry. A UC San Diego School of Medicine team of scientists, headed by senior author Davide Dulcis, PhD, associate professor in the…
A novel imaging technique that uses a synthesized form of scorpion venom to light up brain tumors has shown promise in a clinical trial. The imaging system enables neurosurgeons to better see malignant growths that often are difficult to fully eliminate.
A new vaccination for malignant astrocytoma brings such patients hope. However, research is still in its infancy. We spoke with Professor Michael Platten, Medical Director of the Neurological Clinic at Medical University Mannheim, about the present state of research and the serious opportunities this presents. During the interview, he also revealed how cooperation with the pharmaceutical industry…
A new study provides critical insight into a little-known, yet relatively common, inherited neurological condition called Charcot-Marie-Tooth disease (CMT). The findings point to a pathway to possible treatments for this disease and better understanding of other neurodegenerative disorders, including Alzheimer's disease, that affect millions. The study focused on two related proteins, MFN2 and…
Inside the body, disease and injury can leave behind quite the mess — a scattering of cellular debris, like bits of broken glass, rubber and steel left behind in a car accident. Inside the central nervous system (CNS), a region that includes the brain and spinal cord, it is the job of certain cells, called microglia, to clean up that cellular debris. Microglia have counterparts called…
Some studies have suggested that minerals such as zinc and iron may play a role in how multiple sclerosis (MS) progresses, once people have been diagnosed with it. But little was known about whether zinc, iron and other minerals play a role in the development of the disease. A new study shows no link between dietary intake of several minerals and whether people later develop MS. The study is…
The debilitating behaviours and all-consuming thoughts which affect people with severe obsessive compulsive disorder (OCD), could be significantly improved with targeted deep brain stimulation, according to the findings of a new study. OCD is characterised by unwanted intrusive thoughts (obsessions) and repetitive stereotyped behaviours (compulsions- sometimes called rituals) and often means…
It’s undeniable: the bulk of our population is growing older. Yet, this demographic change has not altered laboratory medicine: the reference values for many analyses are still based on data of a younger cohort. Inevitably this could lead to serious errors in the interpretation of older patients’ test results.
Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation gives us answers to these questions. We spoke with Professor Thomas Wolbers about the problems of diagnosing orientation disturbances and how the measurement of our sense of space could help in the fight against neuro-degenerative illnesses such as Alzheimer’s.
Neurological complications due to infections with (novel) enteroviruses are rarely the focus of medical research. Thus, an article published in the German medical journal Der Nervenarzt (published at the Medizinische Hochschule Hanover (MHH) – has created quite a stir. We spoke with one of the authors, Professor Martin Stangel, about current clinical practice in terms of enterovirus.…
A study has identified chemicals in the skin responsible for a unique scent in people with Parkinson’s disease. The chemicals can be detected in an oily substance secreted from the skin called sebum, the researchers found. The findings suggest Parkinson’s disease could one day be diagnosed from skin swabs, potentially leading to new tests. There are no tests for Parkinson’s disease at…
Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy. “This prediction could help identify children at risk for poor cognitive development shortly after birth with high accuracy,” said senior author John H. Gilmore, MD, Thad and Alice Eure…
With a weak alternating electrical current sent through electrodes attached to the scalp, UNC School of Medicine researchers successfully targeted a naturally occurring electrical pattern in a specific part of the brain and markedly improved depression symptoms in about 70 percent of participants in a clinical study.
A minimally invasive procedure to determine whether patients with drug-resistant epilepsy are candidates for brain surgery is safer, more efficient, and leads to better outcomes than the traditional method, according to new research by The University of Texas Health Science Center at Houston (UTHealth).
