Health and Aging Brain: Health Disparities Study (HABS-HD)
HABS-HD investigates the course and outcome of Alzheimer's disease (AD) in diverse ethnic groups. Participants are African Americans, Mexican Americans, and non-Hispanic Whites aged 50 years and older living in and around the Dallas/Fort Worth area in Texas. Participants are divided into three substudies based on ethnic group: the Health and Aging Brain: Health Disparities, the Health and Aging Brain: Health Disparities Among Blacks and the Health and Aging Brain: Health Disparities Among Hispanics. Over 4,000 participants have completed the baseline data collection as of 2024, and the study continues to recruit. Participants are followed up every 24 to 30 months to monitor their health and cognitive status.
