Early Detection Program Development of Amnestic Mild Cognitive Impairment in the Community : Preliminary Study

ABSTRACT

OBJECTIVE: Mild cognitive impairment (MCI) has high conversion risk to dementia. However, it is not easy to detect amnestic MCI patient early in the community. This study aimed to evaluate the three-stage design for early detection of amnestic MCI in the community. METHODS: Overall 4,385 persons participated who were already registered with Mini Mental Status Examination (MMSE) evaluation. It was conducted in Nam-Gu district, one of the 5 districts of Gwangju, Korea from Jan 1, 2017 to May 31, 2017. We first screened them applying inclusion criteria of over 5-year education and age, gender, education adjusted norm based MMSE Z score between −1.5 and 0. Second stage assessments were done by telephone interviews with asking subjective memory complaints and 5 words list recall tests. And 3rd stage evaluation of neuropsychological tests and clinical interview with visit were performed. RESULTS: We screened 456 of the 4,385 persons and 2nd stage included 51 of the 211 participants telephone interview completed. Twenty-four individuals visited clinic center for 3rd stage evaluation. We finally diagnosed 17 MCI including 16 amnestic MCI and 1 non-amnestic MCI. CONCLUSION: Our three-stage evaluation detected 16 amnestic MCI patients of the 4,385 community dwelling persons with primary screening of MMSE. Our study suggests that this three-stage performance could be effective for early detection of amnestic MCI in large sample community.
