Depression is the most frequently seen neuropsychiatric manifestation in stroke patients. It hampers the ability to undergo therapy and impairs their functional outcome. Depression also increases the risk of suicide in stroke patients, therefore, increasing mortality. The etiology of post-stroke depression (PSD) is complex and reported to be multi-factorial in origin. It also depends on the size and location of the infarct. In addition, family history or prior history of
depressive disorders makes them prone to be affected with depression following a stroke. In this article, we will mention various aspects of PSD, as well as the prevalence and the different screening assessment tools used in literature studies. Although there are many available testing tools, little consistency was seen in them being valid or reliable. We will also discuss the pathophysiology of depression in stroke patients with various available options for managing the condition. We will briefly review the use of alternative treatment such as Electroconvulsive therapy (ECT) and Transcranial Magnetic Stimulation (TMS) as well. However, we need further evidence-based research exploring the screening tool; i.e. universally acceptable for PSD and implementing an effective, non-invasive treatment modality impacting the prognosis. Also, we require further investigations to identify the role of antidepressants in the recovery of stroke patients.
