APOE-epsilon4 carriership and dementia risk over 10 years among Asian American and White older adults.

A common genetic risk factor for dementia affects people of Asian descent the same way it affects others, supporting equitable prevention strategies.

APOE-ε4 carriership confers consistent 10-year dementia risk across Chinese, Japanese, Filipino, and White older adults (risk ratios 1.59-1.96) in a large longitudinal cohort (n=46,325), despite marked differences in carrier prevalence across ethnic groups. These findings support equitable genetic risk counseling and the inclusion of Asian American populations in Alzheimer's disease prevention and screening programs.
