研究目的:

本研究采用随机双盲安慰剂对照试验,探讨中链甘油三酯(medium chain triglyceride, MCT)和二十二碳六烯酸(docosahexaenoic acid,DHA)联合补充对轻度认知障碍(mild cognitive impairment,MCI)老年人认知功能的改善作用,为制定有效合理的MCI预防措施提供科学依据。  

Objectives of Study:

A randomized double-blind placebo-controlled trial will be adopted to explore the effect of medium chain triglyceride (MCT) combined with docosahexaenoic acid (DHA) on cognitive function in the older adults with mild cognitive impairment (MCI), so as to provide a scientific basis for formulating the preventive measure for MCI.
