Abstract
The literature regarding the action mechanism of acupuncture for migraine published from 2013 to 2023 was searched in China National Knowledge Infrastructure (CNKI), Wanfang, VIP, Chinese Science and Technology Periodical Database, PubMed, Medline, and Cochrane Library. The pathogenesis of migraine and potential mechanisms of acupuncture treatment were summarized from the aspects of trigeminovascular system (TGVS), metabolic-related mechanisms, genetic factors, and alterations in brain structure and function. The results revealed that current research on the mechanisms of acupuncture for migraine predominantly centered around the TGVS, with studies confirming the specific regulatory effects of acupuncture on trigeminal system-related components, such as cortical spreading depression (CSD), astrocytes, and neurogenic kinin. While metabolic-related mechanisms and genetic factors are gaining attention, further in-depth exploration is needed to fully understand their roles in the mechanism of acupuncture for migraine. The study of brain structure and function in migraine has advanced, albeit with some controversies. Future research should prioritize larger sample sizes and standardized study designs to delve deeper into the mechanisms of acupuncture in treating migraine.
