Key PointsQuestionIs birth in a state with high stroke mortality associated with dementia risk in a cohort of individuals who all subsequently resided outside of those states? FindingsIn this cohort study, among 7423 Northern California residents with equal access to health care, dementia risk was approximately 27% higher among those born in high stroke mortality states compared with elsewhere. Compared with nonblack persons born outside of high stroke mortality states, black individuals born in a high stroke mortality state had the highest dementia risk, followed by black individuals not born in a high stroke mortality state, and lastly nonblack persons born in a high stroke mortality state. MeaningRacial inequalities in dementia may partially reflect geographic patterning of early-life exposures.
