Lifelong Active Brains Have Fewer Deposits Of Alzheimer's Protein

February 27, 2012

A new study using PET scans to to examine the brains of healthy older people finds those who have been mentally stimulated all their lives, doing things like reading, writing, and playing games and puzzles, have fewer deposits of beta-amyloid, a destructive protein that is a hallmark of Alzheimer's Disease. The researchers suggest their findings will encourage scientists to think differently about how mental stimulation affects the biology of the brain.
