by ETH Zurich Credit: CC0 Public Domain Dementia turns the world upside down, not only for the person affected, but also for their relatives, as brain function gradually declines. Those affected lose their ability to plan, remember things or behave appropriately. At the same time, their motor skills also deteriorate. Ultimately, dementia patients are no longer...
MICHIGAN MEDICINE – UNIVERSITY OF MICHIGAN People over 65 shouldn’t take three or more medicines that act on their brain and nervous system, experts strongly warn, because the drugs can interact and raise the risk of everything from falls to overdoses to memory issues.

“Traumatic brain injury is a major risk factor for dementia, but the reason this is the case has remained mysterious,” said Ted Allison, co-author and professor in the Department of Biological Sciences in the Faculty of Science. “Through this research, we have discovered one important way they are linked—namely, post-injury seizures.” Image credit: pixy.org, CC0 Public Domain “There is currently...
UNIVERSITY OF EXETER New research has found that men who have the Western world’s most common genetic disorder are more likely to develop dementia, compared to those without the faulty genes. Researchers at the University of Exeter and the University of Connecticut have previously found that men with two faulty genes that cause the iron...
by University of Cambridge Credit: Pixabay/CC0 Public Domain Apathy—a lack of interest or motivation—could predict the onset of some forms of dementia many years before symptoms start, offering a ‘window of opportunity’ to treat the disease at an early stage, according to new research from a team of scientists led by Professor James Rowe at the...
