Racial Differences in Cognitive Function and Risk of Incident Stroke.

ABSTRACT:

Background and purpose

Cognitive impairment is associated with increased risk of stroke; however, it is not known whether this association varies by race. Our objective was to examine the association between cognitive function and the risk of stroke among non-Hispanic blacks and whites with no history of stroke.

Methods

Participants were from a population-based cohort study of 7205 older adults (61% black and 59% female) from Chicago's South Side. A standardized composite cognitive function score based on 3 components--global cognition (Mini-Mental State Examination), executive function (Symbol Digits Modalities test), and episodic memory (Delayed and Immediate Story Recall tests)--was used to predict risk of stroke (from Medicare hospitalization data) using a Cox model.
