Post-stroke depression (PSD) is one of the most common neuropsychiatric complications following stroke, with a high incidence rate. Depressive states inhibit the secretion of brain-derived neurotrophic factors and hinder neural repair. Early identification and intervention of PSD are crucial for patients' functional recovery, quality of life, and prognosis. Antidepressants can significantly improve depressive symptoms, and early use of antidepressants can also improve patients' motor and cognitive functions. Combining pharmacotherapy with exercise therapy and occupational therapy can enhance the effectiveness of drug treatment. Early intervention for PSD can correct patients' negative cognition towards post-stroke dysfunction, reduce the risk of depressive relapse, and avoid long-term psychosocial impairment.
