OBJECTIVE: Poststroke depression has been shown to increase mortality for more than 5 years after the stroke. The authors assessed whether antidepressant treatment would reduce poststroke mortality over 9 years of follow-up. METHOD: A total of 104 patients were randomly assigned to receive a 12-week double-blind course of nortriptyline, fluoxetine, or placebo early in the recovery period after a stroke. Mortality data were obtained for all 104 patients 9 years after initiation of the study. Demographic and clinical measurements were collected at 3, 6, 9, 12, 18, and 24 months after the stroke.

Of 53 patients who were given full-dose antidepressants, 36 (67.9%) were alive at follow-up, compared with only 10 (35.7%) of 28 placebo-treated patients, a significant difference. Logistic regression analysis showed that the beneficial effect of antidepressants remaine...
