Objective:
Post-stroke depression (PSD) is the most common psychological disorder in patients with stroke. It not only seriously affects the patient's functional recovery, quality of life, and ability to return to society but also increases stroke recurrence rate and mortality. However, the effectiveness of drug treatment is unpredictable and associated with certain side effects and low compliance. Pharmacological therapy is limited. The field of noninvasive brain stimulation (NIBS) has recently made great progress in developing specific stimulation protocols to alleviate the symptoms of patients with PSD and might offer valid, alternative strategies.
Methods:
We systematically searched PubMed, Embase, and the Cochrane Library for investigating the use of NIBS in the treatment of PSD. The methodological quality of selected studies was assessed according to the Risk of Bias 2 (ROB2).
Results:
We identified 814 references in 3 databases. After excluding irrelevant and duplicate studies, 14 studies were included. According to the PRISMA checklist, 4 studies were overall comprehensive, 6 had some problems, and 4 had considerable problems with the presented information. The evidence was evaluated using ROB2, with 5 "low-risk" studies, 5 "some concerns" studies, and 4 "high-risk" studies included.
Conclusion:
This review provides a comprehensive overview of the clinical trials reported in PSD. Noninvasive brain stimulation is a potentially promising treatment strategy. However, an optimal stimulation protocol needs to be formulated, and much work is required before NIBS can be widely applied in the clinic.
