Abstract
Depression occurs at least temporarily in up to 30 - 40 % of all patients that have experienced a stroke. In the literature the term of a "Poststroke Depression" (PSD) has already been established. However standardised criteria for this diagnoses do not exist to this day. In most cases the DSM or ICD classification system is applied. Other investigators used various psychiatric rating scales. Even though it is generally acknowledged that there is a high prevalence, the occurrence of depression in combination with a stroke fails in most cases to be diagnosed or is left untreated. The need for treatment is even more pronounced by studies showing that a combination of stroke and depression will result in a less favourable outcome, particularly pertaining to that of functional treatment (motor skills, independent participation in activities of daily life). This difference in impairment between a depressed stroke patient and a not depressed stroke patient could be proven in studies that have been conducted over years. Despite the necessity of treatment that can be concluded from such a finding, the recent literature does not offer consistent information as to the ideal point of time for intervention nor the kind and intensity necessitated. According to singular studies, that have rarely been conducted under controlled conditions, there have been positive outcomes after early treatment. Along with psychostimulants that were most predominantly applied in the USA, as well as conventional tricyclic antidepressants, the group of the "Selective Serotonin Reuptake Inhibitors, SSRIs" have resulted in particularly favourable clinical outcomes.
