Diabetes and cognitive systems in older black and white persons
Arvanitakis Z, Bennett DA, Wilson RS, Barnes LL.. Alzheimer disease and associated disorders, 2010-01-01
Topic: Risk, prevention and care in population studies
We examined the association of type 2 diabetes mellitus to function in different cognitive systems in older black and white persons. Participants were 1437 persons (28.1% black; 72.9% women; mean age 78.4 y, education 14.5, Mini-Mental State Examination 27.9) free of dementia, enrolled in the Minority Aging Research Study or Memory and Aging Project, 2 epidemiologic, community-based cohort studies of aging and cognition. Summary measures of 5 cognitive domains and global cognition were derived from 19 neuropsychologic tests. Diabetes, by medication inspection and history, was present in 15.3% participants, including 23.5% blacks and 12.1% whites (P 0.333). In summary, diabetes was associated with semantic memory impairment in both black and white persons. We found similar effects of diabetes on cognition in both racial groups. Because diabetes is twice as common in blacks, the burden of diabetes on cognition is higher in black than white persons.

Key findings
- In summary, diabetes was associated with semantic memory impairment in both black and white persons.
- We found similar effects of diabetes on cognition in both racial groups.
Why it matters
In this cohort, type 2 diabetes was associated with impairment in semantic memory in both black and white older adults. Because diabetes was twice as common in black participants, the burden of diabetes on cognition was higher in black than white persons.
