Effect of acupuncture treatment on vascular cognitive impairment without dementia: study protocol for a randomized controlled trial

摘要

Background Vascular cognitive impairment, no dementia (VCIND) is a condition at risk for future dementia and should be the target of preventive strategies. Preliminary evidence suggests that acupuncture may be a clinically effective intervention for people with early-stage vascular cognitive impairment. We will do a multicenter, 6-month, drug-controlled, nonblinded, randomized, parallel-group trial to determine whether acupuncture is effective for improving cognitive function and quality of life for patients with VCIND. Methods/Design A total of 216 eligible patients will be recruited and randomly assigned acupuncture for two sessions/week (n =?108) or citicoline 300 mg/day (n =?108) in a multicenter, 6-month trial. The primary endpoint is cognition (Alzheimer's Disease Assessment Scale, Cognitive Subscale (ADAS-cog)). Secondary endpoints include assessments of activities of daily living and behavioral symptoms (Clock Drawing Test (CDT), Activities of Daily Living (ADL) and Instrumental Activities of Daily Living scale (IADL)). Discussion This will be the first large-scale trial specifically evaluating acupuncture therapy in VCIND. If the study confirms the effectiveness and safety of acupuncture treatment, it will be important to examine how the acupuncture approach could most effectively be integrated into the provision of routine healthcare. Trial registration This study is registered as an International Standard Randomised Controlled Trial on 17 January 2014, number ISRCTN 82980206
