Exercise, Games, Puzzles Don't Prevent Signs of Alzheimer's in the Brain: Study

 – June 10, 2015  –– 

Physical and mental activity do not appear to prevent the brain from developing the telltale beta-amyloid deposits that are a hallmark of Alzheimer's disease, according to a study published June 10 online in the journal Neurology. Sam Gandy, MD, director of the Center for Cognitive Health at The Mount Sinai Hospital in New York City, said "No one comes in to see a doctor complaining that their head is full of amyloid. The mechanisms underlying the mental benefit of physical and mental activity may well have more to do with how the brain copes with disease, and less to do with controlling how much pathology is present.”
