Non-invasive brain stimulation (NIBS) has the potential to treat generalized anxiety disorder (GAD). To assess the efficacy (response/remission/post-treatment continuous anxiety severity scores) and acceptability (failure to complete treatment for any reason) of NIBS, we searched PubMed, Web of Science, and the Cochrane Library (as of April 2024) for articles on NIBS for GAD and conducted a network meta-analysis of eight randomized trials (20 treatment arms, 405 participants). Data were pooled using standardized mean difference (SMD) and odds ratio (OR) with 95 % confidence interval (CI). Repetitive transcranial magnetic stimulation (rTMS) was the most widely studied treatment for GAD. The right dorsolateral prefrontal cortex (DLPFC) was the most common treatment target for GAD. High-frequency rTMS showed higher response rates (OR 291.40, 95 % CI 13.08 to 6490.21) and remission rates (OR 182.14, 95 % CI 8.72 to 3805.76) compared with other active therapies. Continuous theta burst stimulation (cTBS) greatly improved continuous post-treatment anxiety severity scores (SMD -2.56, 95 % CI -3.16 to -1.96). No significant differences in acceptability were found between the treatment strategies and the sham stimulation group. These findings provide evidence to consider NIBS techniques as alternative or adjunctive treatments for GAD.
