A half hour of aerobic exercise four to five times a week may prevent or slow cognitive decline in older adults who are at a high risk of developing Alzheimer’s, according to a study published Tuesday in the Journal of Alzheimer’s Disease.
“This is the first randomized and controlled trial … to assess effects of exercise on brain structure, function and amyloid burden in older adults who have memory problems, thus, high risks of Alzheimer’s disease,” said lead author Rong Zhang, a neurology professor at UT Southwestern Medical Center.
