Background
Epilepsy is a common and serious chronic neurological disorder, and some patients suffer from cognitive dysfunction. We aim to assess the efficacy and safety of acupuncture combined with traditional Chinese herbal for primary epilepsy patients with cognitive impairment.
Methods
To search the randomized control trials (RCTs) published before April 20, 2023 from PubMed, Embase, Cochrane Library, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Web of science, and Wanfang Database. The risk of bias within each individual trial was evaluated using the Cochrane Collaboration tool. RevMan5.3 software was used for statistical analysis. The odds ratio (OR) or weighted mean difference (WMD) with a 95% confidence interval (CI) was calculated for each RCT before data pooling.
Results
The primary outcomes involve changes in cognitive function and behavioral disturbances. The secondary outcomes focused on quality of life and adverse effects.
Conclusion
The results of this review are expected to provide new guidelines for the treatment of primary epilepsy patients with cognitive impairment.
