Non-pharmacological interventions to treat mood disturbances post-stroke: a systematic review

Abstract

ABSTRACT Background Stroke survivors face high rates of depression, anxiety, and pseudobulbar affect. Clinicians report lack of clarity on effective non-pharmacological interventions due to uncertainty about treatment options as barriers to evidence-based treatment. No systematic review has investigated the effectiveness of non-pharmacological interventions on the conditions of depression, anxiety, and pseudo-bulbar affect. Objectives The aim of this study was to evaluate the effectiveness of non-pharmacological interventions on the outcomes of depression, anxiety, and pseudobulbar affect in post-stroke individuals. Methods Following the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched databases Medline, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PsycINFO for randomized controlled trials in English, within 2012–2023, evaluating the effect of a non-pharmacological intervention on depression, anxiety, and/or pseudobulbar affect. Two researchers screened titles, abstracts, and full texts. One researcher extracted data and assessed risk of bias. Data were synthesized narratively. Results Forty-two studies were included. Intervention types included education (n = 9), psychological therapy (n = 8), and physical exercise (n = 8). Intervention types reporting positive outcomes for depression were psychological therapy (n = 6), physical exercise (n = 3) and robot-assisted therapy (n = 3). Intervention types effective in improving anxiety were physical exercise (n = 2), psychological therapy (n = 3) and multi-modal therapy approaches (n = 2). No studies explored the impact on pseudobulbar affect. Conclusion Non-pharmacological interventions may be effective in improving mood in stroke survivors. Robot-assisted therapy and physical exercise were seen to improve multiple outcome measures. Patient education should be delivered alongside rehabilitation and directed to both stroke-survivor and caregiver.
