Midlife Activity Linked to 45% Dementia Risk Reduction, BU Study Finds
A Boston University–led analysis of the Framingham Heart Study found that higher physical activity levels between ages 45 and 64 are associated with about a 45% lower risk of dementia, with similar benefits extending into older age (about 41% for ages 65–88). The study suggests that regular exercise improves brain health by boosting blood flow and reducing vascular risk factors like hypertension and diabetes, and recommends heart-healthy diets and engaging in social and brain-stimulating activities as complementary strategies.
