About

To determine if adjunctive acupuncture acts as an AD treatment rather than a placebo.

Full description

Acupuncture is used as an adjuvant therapy for Alzheimer's disease (AD), but available evidence for efficacy is weak. The aim is to determine if adjunctive acupuncture acts as an AD treatment rather than a placebo.

This is a randomized, participant-masked, sham-controlled trial. One hundred and sixty participants with mild AD will be randomly assigned (1:1) to either active acupuncture or non-penetrating sham acupuncture (3 times weekly for 14 weeks) added to donepezil treatment (5 mg per day for 28 weeks). The primary efficacy outcome is the change from baseline in the Alzheimer's disease Assessment Scale (ADAS-cog12). Secondary efficacy outcomes include other assessments of the Mini-Mental State Examination (MMSE), the Alzheimer's disease Cooperative Study-Activities of Daily Living (ADCS-ADL), Neuropsychiatric Inventory (NPI).
