What did the U.S. POINTER study find about exercise and brain health?

The U.S. POINTER study, the largest randomized trial of its kind, found that a structured lifestyle intervention — including regular exercise, a healthy diet, cognitive and social engagement, and medical guidance — improved cognitive function in older adults at risk for dementia. Presented at the AAIC 2025 conference, the study enrolled over 2,100 participants and found that those in the structured program performed cognitively at a level comparable to adults one to two years younger.
