Abstract
To assess the influence of depression prior to stroke (PD) on stroke severity on admittance, functional outcome (short- and long-term), mortality, and long-term depression (PSD). Consecutive acute stroke patients were screened for PD. The National Institute of Health Stroke Scale score was obtained on admission. Short-term functional state was registered by the modified Rankin scale and on long-term functional outcome by the Barthel Index. PSD was defined as depression subscale of the hospital anxiety and depression scale (HADSD) >or=11. HADSD and Barthel Index were obtained by postal questionnaire. Survival analyses were performed. Among 771 patients 21.7% had PD. Among 376 patients returning the questionnaire, 8.8% were depressed. On logistic regression analyses severity of stroke on admission, short-term, and long-term functional outcome were independently associated with PD. Logistic regression showed PSD to be independently associated with PD and being unmarried. Cox regression analyses showed that both PD and PSD were associated with high long-term mortality. This study has identified several factors associated with PSD. PD predicts more severe stroke on admittance and less functional improvement both in the short- and the long-term. Both PD and PSD predict higher long-term mortality.Keywords
