Key result
Higher comorbidity scores and stroke history link to worse executive and memory function in African Americans.
Why the study?
Does total comorbid score and specific chronic conditions influence cognitive domains in low socioeconomic status African Americans?
Cross-Sectional (n=384)
Does total comorbid score and specific chronic conditions influence cognitive domains in low socioeconomic status African Americans?
Higher comorbidity burden, particularly stroke, is associated with worse executive and memory functions in low socioeconomic status African Americans, with the impact being greater in younger age groups.

Supports comorbidity-adjusted cognitive assessments in low-SES African Americans; leaves open prospective studies to confirm causality.
Nguyen et al. (2007) conducted a cross-sectional in Low socioeconomic status (n=384). Total comorbid score and specific chronic conditions vs. Lower comorbid score or absence of specific conditions was evaluated on Performance on cognitive tests measuring global ability, executive function, memory function, and perceptual speed. Higher total comorbid scores and history of stroke were inversely associated with executive and memory functions across most age groups in African Americans.
