Background
Stroke is a major cause of morbidity and mortality worldwide. Neuropsychiatric disorders are often associated with stroke and, among them, depression is the most prevalent. Post-stroke Depression (PSD) is related to disability, failure in returning to work, impairment in interpersonal functioning and mortality. Its etiopathogenesis is still uncertain, as well as its treatment. In Brazil, there are few data on the impact of PSD.
Objective
This work is dedicated to conduct a comprehensive review of the concept of PSD, its pathophysiology, morbidity and treatment.
Methods
PubMed, Medline and Lilacs searches of relevant terms yielded 3,265 papers in the last 10 years. We selected original studies and reviews that addressed the aspects mentioned above.
Results
We present the history of the notion of PSD and describe its epidemiology, looking to highlight Brazilian studies. Diagnostic criteria and clinical presentation were detailed, with emphasis on cognitive aspects. The four main pathophysiological theories proposed to PSD are presented and we discuss the various treatment strategies, involving psychopharmacologic options, brain stimulation techniques and psychotherapy.
Discussion
This work provides comprehensive information on PSD, of great utility for clinical practice and research in this topic.
