Study of Healthy Aging in African Americans (STAR)Rates of dementia and Alzheimer’s disease are 40% to 100% higher among African Americans compared to non-Hispanic whites. STAR is a longitudinal cohort study of lifecourse vascular risk and brain aging in 700 African Americans ages 50 and older. The goals of the study are to understand the trajectory of normal cognitive aging from mid- to late life, the burden of cognitive impairment, and the long-term contributions of vascular disease on brain aging among African Americans, an understudied and rapidly expanding segment of the elderly population at higher risk for dementia.
