[Post-stroke depression].

Cerebrovascular diseases are associated with a high incidence of psychiatric disorders. Depressive illness after stroke has been extensively investigated during the last three decades. Post-stroke depression is estimated to occur in 30-35% of the patients during the first year after stroke. Numerous studies have given information on its prevalence, pathogenesis, clinical course, treatment and prevention. Despite the high level of comorbidity, depressive symptoms appear to remain frequently unrecognized and untreated. This has a negative effect on the rehabilitation, quality of live, cognitive function and mortality of stroke patients.
