Overview
Brief Summary
This is a community-based prospective cohort study in Hainan Province, China. The study was initialized in 2023 and included older residents for longitudinal follow-up. The research aims to identify risk factors as well as health and social outcomes that are associated with cognitive impairment in elderly populations, and independently develop AI-assisted software and applications for cognitive enhancement and physical rehabilitation training.

Outcomes
Primary Outcomes
The prevalence and incidence of cognitive impairment base on the communities
Time Frame: An average of 1 to 2 years
Mild cognitive impairment was measured using a Chinese version Mini-Mental State Examination, which was collected by questionnaire. The minimum value of the Mini-Mental State Examination is 0, and the maximum value is 30, the higher the score, the better the cognition outcome.
The prevalence and incidence of dementia using a population-based survey
Time Frame: An average of 1 to 2 years
Dementia was determined by diagnosis of hospitalization or Clinical Dementia Rating Scale (Montreal Cognitive Assessment, MoCA). The minimum value of the MoCA is 0, and the maximum value is 30, the higher the score, the better the outcome. In addition, subtypes of dementia will be based on the specific clinical diagnosis.
The conversion rate of normal to cognitive impairment
Time Frame: An average of 1 to 2 years
Percentage of enrolled population that convert from normal to cognitive impairment
The conversion rate of cognitive impairment to dementia
Time Frame: An average of 1 to 2 years
Percentage of enrolled population that convert from cognitive impairment to dementia
