Mild cognitive impairment (MCI) is considered an intermediate stage between normal aging and dementia
.
Over the past 20 years, the concept of MCI has evolved to accommodate the heterogeneity of etiological and prognostic outcomes, distinguishing MCI into distinct subtypes
Mild cognitive impairment (MCI) is considered an intermediate stage between normal aging and dementia
Over the past two decades, several population-based studies have reported the prevalence of MCI in older Chinese, with prevalence ranging from 5% to 28%
.
The prevalence of MCI ranges widely, in part due to differences in the demographic characteristics of the study populations, as well as differences in the neuropsychological tests and procedures used to define MCI
Over the past two decades, several population-based studies have reported the prevalence of MCI in older Chinese, with prevalence ranging from 5% to 28%
Most previous studies have targeted urban populations with higher education or higher socioeconomic status, while data from rural populations are sparse
With this, Lin Cong et al.
The core objectives are:
This population-based study included 5068 participants (age ≥60 years) living in rural communities
They defined MCI, amnesic MCI (aMCI), and non-amnestic MCI (naMCI) according to Petersen's criteria, which combines neuropsychological assessment with in-person clinical assessment
They found that the overall prevalence of MCI, aMCI, and naMCI was 26.
48%, 22.
The adjusted MCI probability (OR) was: 0.
The significance of the study lies in its findings: In China, more than a quarter of rural older adults are affected by MCI
