STAR - Study of Healthy Aging in African Americans

STAR is a NIH National Institue on Aging (NIA)-funded longitudinal cohort study of lifecourse vascular risk and brain aging in 750 African-Americans aged 50 and older. Goals are to understand the trajectory of normal cognitive aging from midlife to late life, burden of cognitive impairment, and long-term contributions of vascular disease on brain aging in African-Americans, an understudied and rapidly expanding segment of the elderly population at higher risk for dementia.
