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. Professor Kai Gutensohn, Managing Director and Medical Director of AescuLabor…
Where are we coming from? Where are we going? Where are we right now? Our sense of spatial orientation – a complex interaction of various cells in the brain – gives us answers to these questions. In November 2018, around 70 experts in Magdeburg discussed changes in this navigation system induced by age and illness at the ‘Interdisciplinary Symposium on Spatial Cognition in Aging and…
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).
White matter on the brain is a difficult subject. Even the terminology is varied, making differential diagnosis complex. An understanding of prevalence and of the tools available to facilitate the diagnosis of individual diseases is important, Dr Gunther Fesl, radiologist at Praxis Radiologie Augsburg, explains. ‘Differential diagnosis of white matter on the brain is difficult. Even the…
Cancer researchers at the University of Bonn have reported significant progress in the treatment of glioblastoma. About one third of all patients suffer from a particular variant of this most common and aggressive brain tumor. Survival of these patients treated with the new combination therapy increased on average by nearly half compared to patients who received the standard therapy.
‘Night owls’ – those who go to bed and get up later – have fundamental differences in their brain function compared to ‘morning larks’ , which mean they could be disadvantaged by the constraints of a normal working day. Research led by the University of Birmingham in collaboration with researchers at the University of Surrey and the University of Campinas, in Brazil, found that…
The pill could be blurring your social judgement ‒ but perhaps not enough so you'd notice. By challenging women to identify complex emotional expressions like pride or contempt, rather than basic ones like happiness or fear, scientists have revealed subtle changes in emotion recognition associated with oral contraceptive pill (OCP) use. Published in Frontiers in Neuroscience, their study found…
Until now, neurologists were largely convinced that having a higher level of education would build some kind of protective barrier against neurodegenerative diseases like Alzheimer's. But a new study finds that education does not play a role in when the disease starts or how fast it progresses. The study was published in the online issue of Neurology, the medical journal of the American Academy…
Neuroscientists at Emory University School of Medicine have discovered a focal pathway in the brain that when electrically stimulated causes immediate laughter, followed by a sense of calm and happiness, even during awake brain surgery. The effects of stimulation were observed in an epilepsy patient undergoing diagnostic monitoring for seizure diagnosis. These effects were then harnessed to help…
A new study shows that there is a very limited regeneration of cells in the brain of patients diagnosed with multiple sclerosis (MS). These findings underline the importance of treating MS at an early stage of the disease progression, when the affected cells can repair the damage as they are not replaced by new ones. The results are published in the journal Nature by researchers from Karolinska…
