          Abstract

          Background: Little is known about post-stroke depression in patients with lacunar stroke due to cerebral small vessel disease. Our objectives were to describe the prevalence of depression, its correlates and to examine the course of depression over time in a cohort of patients with lacunar stroke, the majority of whom had mild functional disability. Methods: Depression was determined in participants in the international Secondary Prevention of Small Subcortical Strokes (SPS3) trial which is testing antiplatelet therapies and targets of blood pressure control in patients with lacunar strokes and assessing stroke recurrence and cognitive decline. Depression was evaluated using the Patient Health Questionnaire. Multivariable logistic regression models were fitted to examine the relationship between the covariates of interest and depression. Generalized estimating equations were used to examine the likelihood of depression over time, while accounting for the multiple measurements within each subject. Results: The prevalence of depression in 2,477 participants at approximately 4 months after stroke was 19%. Older age (OR 0.97; 95% CI 0.96–0.99), male gender (OR 0.62; 95% CI 0.48–0.80) and less cognitive impairment (OR 0.99; 95% CI 0.98–1.00) were independently associated with a lower risk of depression. Functional disability (OR 1.8; 95% CI 1.3–2.4), living with a spouse/family (OR 1.6; 95% CI 1.1–2.3) and risk factors for stroke (OR 1.2; 95% CI 1.0–1.3) were each independently associated with a higher risk of depression. Longitudinal modeling indicated that the likelihood of depression decreased by 1.12 times (95% CI 1.06–1.17) for each 1-year increase in time. Conclusions: One fifth of those in the SPS3 trial cohort reported depression that is sustained over time. Although this is lower than the prevalence reported for stroke in general, these results underscore the importance of early screening for post-stroke depression, treatment and follow-up to minimize the negative consequences associated with depression.

          Frequency of depression after stroke: a systematic review of observational studies.

          Although depression is an important sequelae of stroke, there is uncertainty regarding its frequency and outcome. We undertook a systematic review of all published nonexperimental studies (to June 2004) with prospective consecutive patient recruitment and quantification of depressive symptoms/illness after stroke. Data were available from 51 studies (reported in 96 publications) conducted between 1977 and 2002. Although frequencies varied considerably across studies, the pooled estimate was 33% (95% confidence interval, 29% to 36%) of all stroke survivors experiencing depression. Differences in case mix and method of mood assessment could explain some of the variation in estimates across studies. The data also suggest that depression resolves spontaneously within several months of onset in the majority of stroke survivors, with few receiving any specific antidepressant therapy or active management. Depression is common among stroke patients, with the risks of occurrence being similar for the early, medium, and late stages of stroke recovery. There is a pressing need for further research to improve clinical practice in this area of stroke care.

            Predictors of depression after stroke: a systematic review of observational studies.

            Although depression is common after stroke, there is uncertainty over its etiology and risk factors, which complicates management. Knowledge of the predictors of depression associated with stroke may allow for the better targeting of therapy, both prevention and treatment. We undertook a systematic review of all published, nonexperimental, population-, hospital-, and rehabilitation-based stroke studies (to June 2004) with prospective, consecutive patient recruitment undertaken to identify variables associated with depressive symptoms (or "illness") after stroke. Assessments were made of the quality of studies including the validity of prognostic models. Data were available from 3 population-based studies including 492 patients, 8 hospital-based studies including 15,272 patients, and 9 rehabilitation-based studies including 2170 patients. Physical disability, stroke severity and cognitive impairment were consistently associated with depression. In addition to the common problem of selection bias, major limitations of these studies included variable selection and poor statistical quality and reporting; small sample sizes meant that only a limited range of variables were analyzed in multivariate models. There is a paucity of well-designed studies of sufficient size to allow stable multivariate predictive models of depression after stroke to be developed. Other than showing that depression is associated with more severe strokes, current evidence does not allow for ready identification of patients most at risk of developing this important complication of stroke.
