How neighborhood, stress, and culture link to Alzheimer’s in African American and Mexican American communities
HABS-HD - Project 3
This project looks at how neighborhood disadvantage, stress, acculturation, and experiences like racism relate to Alzheimer’s brain changes in African American and Mexican American older adults.

What this research studies
You would be asked to join a research program that combines health checks, blood samples or scans for Alzheimer biomarkers, and detailed questionnaires about your neighborhood, stress, and cultural experiences. Researchers will compare these social and environmental measures with biological markers for amyloid, tau, and neurodegeneration and with vascular/metabolic factors. The goal is to see whether social exposures help explain differences in Alzheimer biomarkers and disease progression between African American and Mexican American participants. Participation typically involves clinic visits in the Fort Worth area, medical testing, and completing surveys.
Who could benefit from this research
Good fit: Older adults who identify as African American or Mexican American and are willing to provide health information, biosamples or scans, and complete surveys about their neighborhood and life experiences.
Not a fit: People who are not African American or Mexican American or who cannot travel to the Fort Worth research sites or do not wish to provide medical data or samples are unlikely to benefit from participation.
Why it matters
Potential benefit: If successful, this work could clarify social and neighborhood drivers of Alzheimer risk and guide better-targeted prevention and care for affected communities.
How similar studies have performed: Previous research has linked social, vascular, and inflammatory factors to Alzheimer risk, but combining detailed exposome and sociocultural data with modern biomarker measures in these specific populations is relatively new.
