A Narrative Review on the Non-Pharmacologic Interventions in Post-Stroke Depression

Abstract: Stroke is a major cause of death and disability globally. Post-stroke depression (PSD) is a major driver for poor recovery and poor quality of life with extra burden for the patient and the caregiver. We have previously shown the inflammatory basis of PSD with associated bioenergetic failure, disruption of the blood-brain barrier, cell death, and persistent maladapted inflammation, making the PSD a norm rather than the exception, highlighting the unmet need for therapeutic intervention in PSD across the recovery trajectory. In this era, various interventions are focused on pharmacotherapy; however, non-pill-based medication should also be explored as post-stroke patients are likely to suffer from the adverse effects of polypharmacy. This narrated review explores the status of non-pharmacological interventions in managing PSD. We performed a PubMed search using pre-specified keywords looking at various non-pharmacologic approaches for the management of PSD. Worldwide, approaches such as non-invasive brain stimulation, behavioral and psychosocial therapy, as well as exercise, acupuncture, music, literature, and art therapies are available as monotherapy or adjunctive treatment for PSD. While current literature shows convincing results on the benefits of non-pharmacologic interventions, more robust studies are necessary to determine its utility in PSD.
