Clinical Evaluation on the Therapeutic Effect of Acupuncture Treatment for Alzheimer's Disease

The objective of this proposed study is to evaluate the effect and safety of acupuncture combined therapy on cognitive function, daily living ability and quality of life of Alzheimer's disease by using the international dementia certification scale. In this 12-week, assessor-blind, a Multi-center randomized, controlled study of acupuncture as additional treatment with Donepezil, a total of 180 patients with Alzheimer's disease will be recruited. The patients will be randomly assigned to acupuncture combined with Donepezil (n =90) or Donepezil treatment (n =90). (36 sessions, 3 sessions a week). Changes in the cognition over time measured using ADAS-cog is the primary outcome. MMSE, ADCS-ADL and QOL-AD are the secondary outcomes. The study will be conducted at LongHua Hospital Shanghai University of Traditional Chinese Medicine, Huashan Hospital Fudan University, and Mental Health Center Shanghai Jiao Tong University School of Medicine.

Objective: To evaluate the effect and safety of acupuncture combined therapy on cognitive function, daily living ability and quality of life of Alzheimer's disease by using the international dementia certification scale.

Methods/design: A total of 180 participants with mild to moderate Alzheimer's disease will be randomly assigned to either an acupuncture combined with donepezil group or a donepezil group with a ratio of 1:1. Participants in the acupuncture combined with donepezil group will receive acupuncture treatment in combination with donepezil for 12 weeks and at same time taking donepezil. The main acupoints are DU 24, EX-HN 3, DU 20, EX-HN 1, GB 12, HT 7, KI 6, GB39, and then selecting other acupoints according to TCM syndrome. The electric stimulator will be applied to DU 24, GB 12, HT 7, and LR 3 or SP 6 with a disperse-dense wave of 2/50 Hz, 0.5-1.0 mA. There are 3 sessions per week with each session lasting for 30 min. There will be 12 weeks of treatment for each participant in total. Donepezil 5 mg will be given once daily before bed-time for 12 weeks. After the clinical trial, participants will be given conventional treatment clinically. Participants in the control group will take donepezil only. A follow-up will be conducted 24 weeks after the treatment. The primary outcome is the change and effective rate from baseline in the ADAS-cog score measured at week 12. The secondary outcomes contains The change from baseline in MMSE score, ADCS-ADL score, QOL-AD score measured at weeks 12, 24 and 36.
