But a new study suggests that the changes in the brain that set the stage for Alzheimer’s may start decades -- indeed a lifetime -- before dementia symptoms appear. The latest research found that people as young as 20 have detectable levels of beta-amyloid molecules -- the building blocks of the amyloid plaques that are a key physical signs of Alzheimer’s -- in a group of brain cells that come under attack in Alzheimer's disease. In older people who were cognitively normal at the...
