Background: The early stage of Alzheimer disease might show early memory impairment with normal general cognitive function. Our study aimed to investigate elderly with normal Korean version of mini-mental state examination (KMMSE) score and recall score of 0 for 1 year. We predicted that the patients would show different characteristics and would progress more rapidly compared with normal controls. Methods: This study was based on the data from complete enumeration survey of Mapo-gu Regional Center for Dementia in 2009. We divided all subjects into three groups: subjects with normal K-MMSE scores and recall score of 0 were group 1-1 (n=152), subjects with abnormal K-MMSE scores were group 1-2 (n=64) and subjects with normal K-MMSE scores and recall score of 1 to 3 were group 1-3 (n=941). We compared basic demographics and social characteristics among the three groups. After 1 year (2010), the subjects in group 1-1 (90 out of 152) underwent follow-up examinations for dementia diagnosis. They were also divided into three groups (2-1, 2-2, 2-3) according to K-MMSE and recall scores. Results: Group 1-1 showed different baseline characteristics compared with normal controls. After 1 year, 25.5% (23 out of 90) of the group 2-1 were diagnosed as mild cognitive impairment (n=16) or dementia (n=7). Conclusion: Our study suggested that subjects with normal K-MMSE scores but recall score of 0 are not entirely “normal”. Further detailed evaluation might be needed if memory impairment is suspicious although the K-MMSE scores are within normal range.
