Favorable lifestyle and health linked to lower dementia risk even in people with a genetic risk factor

Article excerpt

Dementia cases are projected to nearly triple globally by 2050, spurring researchers to hunt for prevention strategies. A new study examines whether lifestyle factors, blood pressure control, physical activity, and other health measures, can reduce dementia risk equally across different genetic backgrounds. The question matters because while genetics significantly influence dementia risk, it remains unclear whether favorable lifestyle choices offer the same protective benefit to people with high genetic predisposition as they do to others. Understanding this could reshape how doctors counsel patients with family histories of cognitive decline.
