Now, researchers at the Keck School of Medicine at the University of Southern California are enrolling 100 individuals ages 60 to 80 at risk for Alzheimer’s disease in a trial which will use PET and MRI to determine how physical and cognitive activity may benefit their brain health. The study aims to identify methods to delay Alzheimer’s onset by five or ten years.
