Dementia prevention can’t rely on individual choices alone, new study finds

What the research found
Commentary. Curtin University researchers (Jennifer Dunne and colleagues) write in The Lancet Public Health that dementia prevention still maps mostly to individual behavior. They placed 61 published modifiable risk and protective factors on a socioecological grid: 49 of 61 (80%) sat at the individual level, with few at interpersonal, community, or societal levels (education, housing, neighborhood safety, health-care access, clean air, social connection). Exercise and diet still matter, but only if the surroundings make them possible. This is a framework paper, not a trial of a supplement or a diagnosis. Educational public-health notes, not medical advice.
