Overview
- Researchers at Massachusetts General Hospital reported that 17 overlapping factors shape risk for stroke, dementia and late-life depression, with high blood pressure emerging as the biggest single threat.
- The team linked the three conditions to damage in the brain’s small blood vessels and found that regular mental activity, exercise, a produce-rich diet, light alcohol use, purpose and strong social ties each lowered risk.
- A peer-reviewed paper in Dementia and Geriatric Cognitive Disorders Extra found cognitive performance peaks in the mid-20s and shows a clearer drop around ages 50 to 55, though the pace varies by person.
- A National Institute on Aging study of more than 3,000 people identified five protective habits for thinking skills, including 150 minutes of weekly activity, not smoking, limited alcohol, a Mediterranean-style diet and mentally engaging tasks.
- Neuroradiologist Emer MacSweeney’s 12-question ‘brain age’ quiz, shared in mass media, is framed as a quick awareness check to nudge healthier routines rather than a clinical diagnosis.
