Poststroke depression: prevalence, course, and associated factors

Despite the considerable amount of research that has been undertaken on poststroke depression, a review of the literature demonstrates that there are many inconclusive findings in the area. In particular, the causes and course of the disorder remain to be firmly established. While studies of prevalence differ with respect to the nature and timing of their assessment procedures, most conclude that poststroke depression has a negative impact on the rehabilitation of the stroke patient. Very little research is available on te relationship between poststroke depression and care-giver burden. However, recent studies have adopted more rigorous methodological procedures, allowing some insights into the complex mixture of factors which determine the occurrence of poststroke depression.
