Ethnoracial Differences in Lewy Body Diseases with Cognitive Impairment
Andrea M Kurasz, Glenn E Smith, Maria G McFarland, Melissa J Armstrong. Journal of Alzheimer's disease : JAD, 2020
Topic: Brain imaging, connectivity and assessment
Presentation age was similar between groups (median 74-75 years). Compared to Whites (n = 1782), African Americans (n = 130) and Hispanics (n = 122) were more likely to be female and single, have less educational attainment, report more cardiovascular risk factors, describe less medication use, and perform worse on select cognitive tests. Hispanics reported more depressive symptoms. Cohorts differences highlight the need for population-based LBD studies with racial-ethnic diversity. Culturally-sensitive neuropsychological tests are needed to determine whether observed differences relate to cultural, social, testing, or disease-related factors. More research is needed regarding how social and biological factors impact LBD care among diverse populations.
Key findings
- Presentation age was similar between groups (median 74-75 years).
- Compared to Whites (n = 1782), African Americans (n = 130) and Hispanics (n = 122) were more likely to be female and single, have less educational attainment, report more cardiovascular risk factors, describe less medication use, and perform worse on select cognitive tests.
- Hispanics reported more depressive symptoms.
- Cohorts differences highlight the need for population-based LBD studies with racial-ethnic diversity.
- Culturally-sensitive neuropsychological tests are needed to determine whether observed differences relate to cultural, social, testing, or disease-related factors.

How this study scored 50/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record, multi-centre collaboration and free to read, so those were left out: it earned 28 of the 56 points we could judge it on, which is 50 out of 100.
