Different acupuncture and moxibustion therapies for mild cognitive impairment: a network meta-analysis

To investigate the effectiveness of different acupuncture and moxibustion therapies in improving cognitive function in patients with mild cognitive impairment (MCI) to determine the optimal approach. This study aims to provide insights into the treatment of MCI patients for future randomized controlled trials (RCTs) and clinical decision-making.RCT studies were retrieved from databases including PubMed, Embase, Cochrane Library, Web of Science, CNKI, WANFANG, VIP, and SinoMed. The Cochrane risk of bias tool was used to assess the risk of bias for eligible trials. Bayesian network meta-analysis was conducted using R4.2.3 software.A total of 46 RCTs with 3641 participants were included. The network meta-analysis showed that acupoint pressing + cognitive training + auricular point sticking, massage + western medicine treatment, and electroacupuncture + western medicine treatment ranked first, second, and third in improving MMSE score, respectively. Acupoint pressing + cognitive training, cognitive training + scalp acupuncture, and cognitive training + moxibustion ranked first, second, and third in improving MoCA score, respectively.This study showed that acupoint pressing alone or acupoint pressing + auricular point sticking may improve cognitive function in MCI patients and possibly be the most effective acupuncture interventions for the treatment of MCI.
