Hypothesis
Does self-reported discrimination affect brain imaging findings associated with aging and Alzheimer's disease across different racial/ethnic groups?
Conclusion
Experiencing racial discrimination is linked to greater brain health issues, particularly in Black adults.
Supporting Evidence
- Black and Hispanic adults are at greater risk for Alzheimer's disease compared to White adults.
- Racial discrimination was positively associated with greater white matter hyperintensity volume.
- Stronger associations between racial discrimination and brain health were found in Black participants.
Takeaway
If people face discrimination, it can hurt their brain health, especially for Black people.
Methodology
Data from the MESA study was used, involving brain imaging and regression models adjusted for various covariates.
Participant Demographics
6814 participants initially enrolled, including 38% White, 28% Black, 22% Hispanic, and 12% Chinese Americans.
