Three Midlife Health Habits Linked to 13 Extra Dementia-Free Years
In a long-term study of 12,409 adults (average age ~56), those with no history of high blood pressure, diabetes, or smoking lived about 30.1 years dementia-free, compared with ~17.5 years for those with all three risk factors—roughly 13 fewer dementia-free years. The findings varied by sex and race (women and White participants fared better). The study shows association, not causation, but suggests midlife prevention of vascular risks may delay dementia and help preserve brain health, alongside other healthy habits; risk factors were only measured once.
