Brain behavior relationships among African Americans, whites, and Hispanics
DeCarli C, Reed BR, Jagust W, Martinez O, Ortega M, Mungas D.. Alzheimer disease and associated disorders, 2008-10-01
Topic: Risk, prevention and care in population studies
Hispanic subjects were, on average, significantly younger and had less years of education than African Americans or whites. Whites with dementia were significantly older than both African American and Hispanic dementia patients. Highly significant differences in MRI measures were associated with clinical diagnoses for the group as a whole after adjusting for the effects of age, sex, education, race, and ethnicity. Subsequent independent analyses by racial and ethnic status revealed consistent relationships between diagnostic category and MRI measures. Clinical diagnoses were associated with consistent differences in brain structure among a group of racially and ethnically diverse individuals. We believe these results help to validate current diagnostic assessment of individuals across a broad range of racial, ethnic, linguistic, and educational backgrounds.

Key findings
- Hispanic subjects were, on average, significantly younger and had less years of education than African Americans or whites.
- Whites with dementia were significantly older than both African American and Hispanic dementia patients.
- Highly significant differences in MRI measures were associated with clinical diagnoses for the group as a whole after adjusting for the effects of age, sex, education, race, and ethnicity.
- Subsequent independent analyses by racial and ethnic status revealed consistent relationships between diagnostic category and MRI measures.
- Clinical diagnoses were associated with consistent differences in brain structure among a group of racially and ethnically diverse individuals.
Why it matters
Clinical dementia diagnoses were associated with consistent differences in brain structure on MRI across African American, white, and Hispanic participants. This helps validate diagnostic assessment across diverse groups but does not treat, cure, or prevent dementia.
