Abstract

In a prospective study of mood disorders in 103 stroke patients, we examined the predictive value of affective, cognitive, social and neurologic variables obtained in-hospital and at six months poststroke in terms of outcome as determined by the same measures at one and two years follow-up. The following factors were found to have prognostic significance: 1) Lesion Location: proximity of the lesion on CT scan to the frontal pole in patients with left anterior infarcts showed a strong positive relationship with severity of depression at one year but not at two years poststroke. 2) Affective Status: depression (in-hospital and at 6 months) strongly predicted depression at one year but at two years poststroke. Additionally, in-hospital depression significantly correlated with physical impairment at two years, while depression at six months bore a moderate relationship to physical impairment at one year. 3) Physical Impairment: impairment in activities of daily living in-hospital bore a modest relationship to depression at one year while such impairment at six months correlated strongly with depression at both one and two years. These findings may reflect the natural course of major depression which remits between one and two years poststroke. Although stroke lesion location is the strongest predictor of subsequent depression, there appears to be a reciprocal relationship between physical impairment and depression (i.e., depression predicts impairment and impairment predicts depression). Since poststroke depressions are amenable to therapeutic intervention, these prognostic factors may have implications for the treatment and rehabilitation of stroke patients.
