Functional impairment associated with acute poststroke depression: the Stroke Data Bank Study.

ABSTRACT

To examine the independent association of depression following acute stroke with impairment in activities of daily living (ADL), the authors conducted a cross-sectional analysis of stroke patients enrolled in the Stroke Data Bank (U.S.A.) who had completed the Center for Epidemiological Studies Depression Scale (CES-D). Scores on the Barthel Index, a measure of ADL, were compared between depressed (CES-D > or = 16) and nondepressed patients (CES-D < or = 15) at 7-10 days after stroke. Of the 626 who completed CES-D, 160 were depressed. Depressed stroke patients evidenced greater impairment in ADL than nondepressed patients, independently of all other factors that influenced poststroke physical disabilities. CES-D scores were negatively correlated with Barthel scores in the entire stroke population. Neurological factors, greater age, poor prestroke physical activity, and prestroke disturbances in sexual functioning were also independently associated with limitations in functional status of stroke patients.
