05/09/2016Scientists from Tomsk Polytechnic University and Siberian State Medical University are developing an early diagnosis system for neurodegenerative disorders. The diagnosis system is based on virtual reality (VR) – a person is immersed in a virtual environment to carry out some functional tests. Researchers vary the parameters of the virtual environment and record changes in the person’s movements.

(LZH) are developing a new in-situ test method to examine the hazardous potential of chemical substances.
16/08/2016Brain scans have revealed how a genetic mutation linked to major psychiatric disorders affects the structure, function and chemistry of the brain.
16/08/2016Researchers at Technical University of Munich discovered that our brain actively takes sugar from the blood. Prior to this, researchers around the world had assumed that this was a purely passive process.
15/08/2016Eight people who have spent years paralyzed from spinal cord injuries have regained partial sensation and muscle control in their lower limbs after training with brain-controlled robotics.
04/08/2016From middle-age, the brains of obese individuals display differences in white matter similar to those in lean individuals ten years their senior, according to new research led by the University of Cambridge. White matter is the tissue that connects areas of the brain and allows for information to be communicated between regions.
01/08/2016Researchers at CNRS, INSERM, Aix-Marseille University and AP-HM have just created a virtual brain that can reconstitute the brain of a person affected by epilepsy for the first time. From this work we understand better how the disease works and can also better prepare for surgery. These results are published in Neuroimage.
22/07/2016Using a robust model for Parkinson's disease, University of Alabama at Birmingham researchers and colleagues have discovered an interaction in neurons that contributes to Parkinson's disease, and they have shown that drugs now under development may block the process.
22/07/2016Millions of people all over the world suffer from partial blindness – caused by glaucoma, a stroke or traumatic brain injury. For years, the loss of vision was deemed irreversible. But now a new treatment makes it possible to improve eyesight and vision.
22/07/2016The study, led by IRB Barcelona and published in Nature Communications will help research into regenerative medicine and potentially also help understand neurodegenerative diseases such as Alzheimer’s.
21/07/2016The World Federation of Neurology (WFN) invites the people to observe the World Brain Day for the third time in 2016. This year’s motto is “The ageing brain”. The focus lies on prevention of and dealing with the neurological diseases stroke, Alzheimer’s disease and Parkinson’s disease, since the risk to fall ill with them increases with age.
20/07/2016A mathematician at the University of Strathclyde has shared in a prestigious prize for research into methods for accelerating the diagnosis of strokes.
15/07/2016Ideally, injectable or implantable medical devices should not only be small and electrically functional, they should be soft, like the body tissues with which they interact. Scientists from two UChicago labs set out to see if they could design a material with all three of those properties.
12/07/2016Scientists at the University of Exeter have developed a pioneering new technique that could revolutionize the surgical treatment of epilepsy.
06/07/2016Clinical trial data published in the Proceedings of the National Academy of Sciences (PNAS) demonstrates stimulating the vagus nerve with an implantable bioelectronic device significantly improved measures of disease activity in patients with rheumatoid arthritis (RA).
05/07/2016USC researcher Megan L. McCain and colleagues have devised a way to develop bigger, stronger muscle fibers. But instead of popping up on the bicep of a bodybuilder, these muscles grow on a tiny scaffold or "chip" molded from a type of water-logged gel made from gelatin.
04/07/2016A clinical trial testing mobile videoconferencing as a means for physicians to diagnose stroke patients while they're being transported to the hospital has found that a tablet-based system produced diagnoses highly correlating with a bedside assessment -- a finding that could have important implications for the early treatment of stroke and for preventing the disability it causes.
01/12/2015Multiple sclerosis apparently can strike anyone - regardless of age, family history, lifestyle or gender. Yet why then does it not strike everyone? Genetic and environmental factors appear not to be the only reason whether it develops or not. The countless microorganisms that colonize our intestinal tract could also be involved in this.
01/07/2015When measuring myocardial activity, it is important for the skin to always stay moist under the electrodes of the ECG. Only then can data be consistently transferred. Athletes have an easier time with this: they are used to sweating. This is a lot harder for older patients.
08/05/2015The bowel is surrounded by a dense plexus of nervous tissue that presents problems for surgeons. On the one hand, it is difficult to distinguish from the surrounding tissue; while on the other hand, sometimes portions of it need to be removed when parts of the colon are removed. Yet injuring these nerves can result in permanent damage.
01/12/2014How does a physician handle a patient, who wants to die and what rights do I actually have as a patient? Legal practitioners do not automatically answer these and other questions. We talked about this subject with MD-PhD Ralf Jox from the Institute of Ethics, History and Theory of Medicine at the Ludwig Maximilians University of Munich, Germany.
01/09/2014The public only notices diseases when celebrities become patients: in the spring of 2014, Formula One driver Michael Schumacher fell into a coma for several months as the result of a head injury caused by a skiing accident. These types of accidents show how delicate the brain responds to injuries. Brain stimulation could possibly support the rehabilitation of vegetative patients.
01/07/2014In patients with Parkinson's, neural cells in the brain die off that produce the neurotransmitter dopamine. Certain physical symptoms that can indicate the disease follow years later. But a reliable diagnosis can only be made through examination of the brain after the patient's death, and not during his lifetime.
