Research advances on mild cognitive impairment subtypes and their influencing factors / 中华老年医学杂志

ABSTRACT

Mild cognitive impairment(MCI)is a prodromal phase of dementia with heterogeneity in etiology, clinical presentation, disease progression, outcome, and prognosis.The number of studies on MCI subtypes is increasing each year.This article discussed the subtypes of MCI from the perspectives of phenotypic characteristics, etiology, progression, outcome, and data-driven approaches, and further summarizes the epidemiological characteristics, influencing factors, and risk of progression to dementia of each subtype.Despite the increasing number of studies on MCI subtyping, research remains limited on the correlation between MCI subtypes from different perspectives, indicating a need for further investigation in order to achieve more accurate and effective diagnosis and treatment of MCI and obtain evidence for dementia prevention.
