Background Amnestic mild cognitive impairment (aMCI), a common neurodegenerative disease affecting older adults, has garnered significant research interest over the past few years. While previous studies have suggested that acupuncture holds promise as a clinical intervention to improve cognitive function in patients with aMCI, the long-term effect of acupuncture treatment for aMCI remains unclear. Methods This is a multicenter, single-blinded, randomized controlled trial (RCT) with a long-term follow-up.166 patients diagnosed with aMCI will be randomly divided into acupuncture group (AG) and sham acupuncture group (SA). The intervention will last for 12 weeks (2 sessions per week), follow-up for 48 weeks, and the study will last a total of 60 weeks. The primary outcomes are the changes in the Alzheimer’s Disease Assessment Scale-Cognitive (ADAS-Cog) score from baseline to week 12 and from baseline to week 60. Generalized estimating equations (GEE) will be used to assess the impact of the acupuncture intervention on outcome variables over time at baseline and weeks 12, 24, 48, and 60. Discussion This protocol outlines a detailed procedure for a multicenter RCT designed to further evaluate the long-term effect of acupuncture in managing aMCI. We anticipate that the findings of this research will provide valuable insights and evidence-based recommendations for the clinical management of this patient population. Trial registration The trial was registered at Chinese Clinical Trial Registry on 28 May 2024 (Number: ChiCTR2400084932).
