Mild cognitive impairment (MCI) is an intermediate stage in the trajectory from normal cognition to dementia. Despite controversies about the classification of MCI, recent published criteria for MCI allow better comparison of the prevalence, incidence, and outcomes of MCI. Subjects with MCI have a high rate of progression to dementia over a relatively short period. In this review, we present an overview of the classification of MCI, estimates of the incidence and prevalence of MCI, risk factors for MCI, and the outcomes following an MCI diagnosis.
轻度认知障碍(MCI)是从正常认知到痴呆的轨迹中的一个中间阶段。尽管关于 MCI 的分类存在争议,但最近发表的 MCI 标准允许更好地比较 MCI 的患病率、发病率和结局。MCI 患者在相对较短的时间内向痴呆进展的比例较高。在这篇综述中,我们介绍了 MCI 的分类概述、MCI 的发病率和患病率估计、MCI 的危险因素以及 MCI 诊断后的结局。
