[Post-stroke depression: recognition and treatment interventions]

Depression is the most common neuropsychiatric complication of a stroke (Post Stroke DepressionPSD) and has been shown to impede the recovery and rehabilitation of these patients. Prevalence rates of PSD vary between 6% and 79%. Direct comparison between studies is limited due to their different methodology. Etiology of PSD is determined by biological and psychosocial factors. Symptoms of PSD appear in three areas: affective, somatic and cognitive. Differential diagnosis includes post-stroke fatigue and pseudo-depressive manifestations of ischemic infarctions (apathy, aprosody, athymhormia, pseudobulbar palsy). Mortality in post-stroke patients is higher than in non-depressed stroke patients and suicide ideation is observed in 6.6-11.3% of stroke patients. Selective serotonin reuptake inhibitors (SSRI) are considered as the first choice treatment of PSD. Other therapeutic approaches include cognitive and functional rehabilitation. PSD is a potentially treatable condition, yet under-diagnosed, and has a negative effect on functional recovery and survival of stroke patients.
