A major new study from the UC Davis Alzheimer’s Center has uncovered dramatic differences in the brains of Hispanics with a dementia diagnosis compared with those of non-Hispanic whites and of African Americans.
The first-of-its-kind study, based on extensive analyses of autopsied brains, found that Hispanics diagnosed with dementia were much more likely to have cerebrovascular disease than either non-Hispanic whites or African Americans. Researchers also found that Hispanics and African Americans were more likely to have mixed pathologies, that is, a combination of Alzheimer’s disease and cerebrovascular disease, than non-Hispanic whites. And non-Hispanic whites were shown to have more pure Alzheimer’s disease than either Hispanics or African Americans.
Published today in the Journal of Alzheimer’s Disease, the findings may help explain the higher rates of dementia among blacks and Hispanics, and point to the importance of treating each patient based on their individual risk factors.
