Fohner Quantifies the Contribution of Dementia Risk Factors
Posted: 2/12/2026 (CSDE Research)
CSDE Affiliate Alison Fohner (Epidemiology) and co-authors published a study in Alzheimer’s & Dementia that quantified the contribution of dementia risk factors in midlife (45-64 years) and late life (≥ 65 years) in the United States. The team used nationally representative data from six community-based cohorts in the Dementia Risk Prediction Project (DRPP). Fohner and co-authors observed that midlife and late-life risk factors contributed to 22.7% and 16.5% of dementia cases, respectively. Midlife obesity, late-life physical inactivity, and lower education appear to be the greatest contributors to dementia risk.
