Purpose : The purpose of this study to present normative data and cut-off point for older Korean adults completing the Montreal cognitive assessment-Korea(MoCA-K), which is used as a screening test for mild cognitive impairment in Korea.
Methods : This study recruited 195 healthy adults aged ≥60 years in community. All participants completed the MoCA-K and MMSE-K to assess their cognitive function. Participants were divided into six groups based on their age: 60~64 years, 65~69 years, 70~74 years, 75~79 years, 80~84 years, and 85~89 years.
Results : The results of the MoCA-K showed that score decreased significantly with age (p<.001) and increased significantly with educational level (p<.001). The optimal cutoff points were 24/25 for 60-69 years old, 21/22 for 70-79 years old, 17/18 for 80-84 years old, and 13/14 for 85-89 years old. The optimal cutoff points were 15/16 for illiterate individuals, 22/23 for individuals with 6 years of education, 22/24 for individuals with 9 years of education, and 26/27 for individuals with 12 or more years of education.
Conclusions : This study provides normative data and cut-off point for the MoCA-K test in the older Korean adults. These data will facilitate more accurate detection and follow-up of the risk of mild cognitive impairment in this population, taking into account age, and education. Future studies should focus on the cut-off score on the level of education according to age.
