Efficacy of Cranial Electrical Stimulation on cognition among perimenopausal women

The study examined the effects of Cranial Electrical Stimulation (CES) on cognitive function in perimenopausal women. It involves a non-randomized experimental design with 30 participants (Active CES: n=23, Sham CES: n=7) who received CES for 30 minutes, four days a week, for four weeks. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) before and after the intervention. Both groups showed significant improvement in cognition, but there was no statistically significant difference between active and sham CES. The study concludes that while CES may enhance cognitive function, further research is needed to establish its distinct effects. No adverse events were reported.

本研究考察了颅电刺激（Cranial Electrical Stimulation, CES）对围绝经期女性认知功能的影响。本研究采用非随机化实验设计，共纳入30名受试者（主动CES组：n=23，假手术CES组：n=7），所有受试者均接受每周4次、每次30分钟的CES干预，干预周期共4周。研究于干预前后采用蒙特利尔认知评估量表（Montreal Cognitive Assessment, MoCA）对受试者的认知功能进行评估。两组受试者的认知功能均出现显著改善，但主动CES组与假手术CES组间未观察到具有统计学意义的差异。本研究得出结论：尽管CES或可改善认知功能，但仍需开展进一步研究以明确其独立作用效果。本研究未报告任何不良事件。
