Scientists close in on a blood test for Alzheimer's disease Researchers are nearing development of a blood test that can accurately detect the presence of Alzheimer's disease, which would give physicians an opportunity to intervene at the earliest, most treatable stage.
Brain connectivity changes with working memory after TBI Scientists compared information flow in the brain in traumatic brain injury and controls using neuroimaging and a novel working memory task, CapMan, which measures capacity and mental manipulation. This is the first study to show causal relationship between these tasks of working memory and fronto-parietal regions
Researchers develop drug delivery technique to bypass blood-brain barrier Researchers have successfully prevented the development of Parkinson's disease in a mouse using new techniques to deliver drugs across the naturally impenetrable blood-brain barrier. Their findings lend hope to patients around the world with neurological conditions that are difficult to treat due to a barrier mechanism that prevents approximately 98 percent of drugs from reaching the brain and central nervous system.
Stimulating specific brain area could help defrost arms frozen by stroke Little can be done to help the hundreds of thousands of people whose severe strokes have left them with one arm stuck close to the sides of their bodies like a broken wing. A 30-patient study, however, has found that magnetically stimulating a specific part of their brains can affect arm movements -- raising hope that, in the future, a short course of therapy targeting this area could help to free the arm and restore some use of the stroke-affected limb
