Alzheimer's disease

What it is

Alzheimer's disease is the most common cause of dementia, marked by amyloid plaques and tau tangles in the brain and a slow loss of memory and function over years. Two antibody drugs that clear amyloid are approved in some countries but slow decline only modestly and carry bleeding and swelling risks, so research attention is shifting to earlier blood-test diagnosis, inflammation, metabolism and prevention through blood pressure, hearing and activity. Mouse and cell studies make up much of the daily coverage and rarely translate directly.
