Can Dementia Be Prevented? What Research Shows About Brain Health
This article explains that while there’s no guaranteed way to prevent dementia, strong research shows many steps can lower risk or delay onset—especially when started in midlife. The most supported actions include controlling blood pressure, diabetes, and cholesterol; being physically active; not smoking; limiting alcohol; eating a Mediterranean/MIND-style diet; treating hearing loss; prioritizing sleep; staying socially connected; and engaging in mentally stimulating activities. It also clarifies where evidence is weaker (for example, supplements and “brain games” offer limited benefit) and highlights that genetics influence risk but do not erase the value of healthy habits. Patients and caregivers will find clear, practical guidance to discuss with clinicians and to tailor a brain-health plan that fits their goals, abilities, and life stage.
