轻度认知障碍（Mild Cognitive Impairment, MCI）是介于正常老化与阿尔茨海默病（Alzheimer’s Disease, AD）之间的一种临床状态，患者一般的认知功能和生活能力保持完好，尚未达到AD的诊断标准。由于MCI被认为是AD的前期状态，而AD中晚期疗效不佳，故对MCI研究已成为国内外研究的热点。MCI在治疗上大多是沿用对AD治疗的药物，疗效尚不确定，因此研究中医对MCI的认识和治疗更能体现中医特色。本文主要从中医对MCI的认识、辨证分型标准及中医药治疗方法等方面对其进行系统的综述，以期进一步掌握MCI的动态，为提高中医药疗效、降低AD的发病率提供参考。

Mild cognitive impairment (MCI) is considered as an intermediate clinical state between normal aging and Alzheimer’s disease (AD). The cognitive function and life ability of patients are normal, which have not met the criteria of AD. MCI is considered to be an earlier stage of AD. The clinical effects of AD in the middle or late stage are unsatisfactory. Therefore, studies on MCI have become the hot research areas both at home and abroad. The therapy of MCI is similar to AD. The treatment effect is uncertain. Hence, the understanding and treatment of MCI by TCM reflected TCM features. This article reviewed on TCM understanding of MCI, TCM syndrome differentiation criteria and TCM treatment methods of MCJ. Thus, it was aimed to further understand the dynamic of MCI in order to provide references for improving TCM clinical effects and reducing the incidence of AD.
