Research 

Taiwan is a rapidly aging society. The elderly with mild cognitive impairment (MCI) have increased risk of dementia, and this is a population-based report using standard neuropsychological tests and expert consensus diagnosis to assess the MCI prevalence and its associated factors in Taiwan.

​

Of 470 participants recruited between 2017 and 2019 (mean age 71.2 ± 5.4 years), the prevalence of MCI was higher in the rural area than in the urban area (25.1% vs. 10.8%, p < 0.001) after standardized for age, gender, and level of education. Having lower education and having depression symptoms were consistently associated with increased risk of MCI in both urban and rural areas (p < 0.05). Being male and diabetes were additionally associated with MCI prevalence in urban areas.
