Clinical Evaluation of Acupuncture Treatment on Alzheimer's Disease in APOE e4 Carriers and Non-Carriers

This is a two-centre randomized controlled trial. A total of 176 participants with mild-to-moderate Alzheimer's disease, 88 APOE e4 carriers and 88 non-carriers, will be randomly assigned to either an acupuncture combined with donepezil group or a sham acupuncture combined with donepezil group with a ratio of 1:1. The main acupoints are DU 24, EX-HN 3, DU 20, EX-HN 1, GB 12, HT 7, KI 6, GB39. There will be 12 weeks of 3-session treatment for each participant, and a 52-week follow-up in total. The primary outcome is the change and effective rate from baseline in the ADAS-cog score measured at Week 12.
