Background: Patients with post-stroke memory disorder (PSMD) have poor quality of life and it is necessary to identify more beneficial stimulation protocols for treatment with repetitive transcranial magnetic stimulation (rTMS). This meta-analysis was conducted to investigate the efficacy and safety of rTMS for improving memory performance, global cognition, and activities of daily living (ADL) among patients with PSMD. Methods: The PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Chinese Biomedical Literature Database, Chinese National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang databases were screened to identify relevant randomized controlled trials. The primary outcome was memory performance; secondary outcomes included global cognition, ADL, and adverse events. STATA software was used to perform data synthesis. Results: Five articles with a total of 192 participants were included. The results indicated that rTMS was superior to control treatments for improving memory performance (mean difference [MD] = 1.73, 95% CI [Confidence Interval] [0.85, 2.60], p 0.001), global cognition (MD = 2.44, 95% CI [0.96, 3.93], p 0.001), and ADL (MD = 10.29, 95% CI [5.10, 15.48], p 0.001). No significant differences were found between the low-frequency (LF) and high-frequency (HF) rTMS subgroups (p = 0.47, I{}^{\mathrm{2}} = 0.00%) or between the sham rTMS and non-rTMS subgroups (p = 0.94, I{}^{\mathrm{2}} = 0.00%). Four studies did not reported adverse events. Conclusions: rTMS may improve memory function, global cognition, and the ability to perform ADL in patients with PSMD. LF-rTMS and HF-rTMS may have equal efficacy for treatment of PSMD. Future studies should consider extending the follow-up period to explore the safety and long-term efficacy of rTMS for treatment of PSMD and the appropriate choice of placebo for clinical trials of this treatment.
