Risk factors for and correlates of poststroke depression following discontinuation of antidepressants.
ABSTRACT The authors randomly assigned nondepressed patients at least 3 months poststroke to receive nortriptyline, fluoxetine, or placebo for 3 months using double-blind methodology. Patients were followed at 3, 6, 9, and 21 months for new onset of depression. In patients treated with antidepressants, lesion volume and degree of social impairment were associated with subsequent late-onset of poststroke depression at 6 and 9 months. In the placebo group, severity of impairment in activities of daily living, at 3 and 9 months, was associated with late onset poststroke depression. Differences in the clinical/pathological correlates may reflect subtle differences in the pathophysiology of poststroke depression following prophylactic antidepressants.

ABSTRACT: Depression may affect patients' recovery and even their survival rate after stroke, but it is often overlooked or inadequately managed; data regarding the prophylactic efficacy and safety of fluoxetine are inconsistent in this setting. The objective of the study is to systematically assess the prophylactic efficacy and safety of fluoxetine for poststroke depression in patients with stroke. We searched electronic databases up to December 2009 for studies evaluating the prophylactic efficacy of fluoxetine in patients with stroke. The pooled odds ratio (OR), weighted mean difference (WMD), incremental efficiency and 95% confidence intervals (95% CI) were calculated. We collected and evaluated a total of 385 patients identified from six trials. Meta-analysis demonstrated that fluoxetine reduced the incidence of poststroke depression (PSD) (OR = 0.25, 95% CI 0.11 to 0.56), helped recovery in neurological function (WMD = -4.72, 95% CI -8.31 to -1.13) and improved independence in activities of daily living (WMD = -8.04, 95% CI -13.40 to -2.68); fluoxetine is relatively safe in spite of the adverse events (OR = 0.88, 95% CI 0.31 to 2.49, p = 0.82). However, fluoxetine groups and control groups did not differ in change of scores for depression (WMD = -3.97, 95% CI -9.85 to 1.90, p = 0.19). Fluoxetine was beneficial for the prophylaxis of poststroke depression in patients with stroke but not in reducing symptom severity of PSD.International Journal of Clinical Practice 08/2010; 64(9):1310-7.
