TL;DR Summary

New Neurology Open Access findings show that midlife type 2 diabetes, smoking, and high blood pressure substantially raise dementia risk; people with all three risk factors were more than twice as likely to develop dementia, and those with none had about 30 dementia-free years versus 17.5 years with all three, suggesting a potential ~13-year delay if vascular risks are managed. The study shows association, not causation, and experts urge lifestyle changes—DASH-style diet, regular exercise, adequate sleep, and quitting smoking—to protect brain health.
