Objectives: This study was tried to know usefulness of the Montreal Cognitive Assessment(MoCA) to detect mild cognitive impairment(MCI), to identify any differences according to items, and to disclose variables associated with MoCA.
Methods: The MoCA-K(Korean Version of the Montreal Cognitive Assessment) and the MMSE-K(Korean Version of the Mini-Mental State Examination) were performed to normal controls(N=25), patients with MCI(N=27), and patients with dementia of the Alzheimer’s type(N=26).
Results: 1) At cut-off of 23/24, sensitivity of the MoCA-K to detect MCI was 70% and specificity was 92%. While sensitivity of the MMSE-K was 11%, and specificity was 96%. In general, the MoCA-K had higher sensitivity than the MMSE-K, while specificity was similar. 2) There were more differences in items of the MoCA than those of the MMSE, especially in attention and abstraction(p＜0.001, respectively). 3) Total scores of the MoCA-K had positive correlation with total scores of the MMSE-K(γ=0.879, p＜0.01) and education(γ=0.489, p＜0.01), and negative correlation with age(γ=-0.550, p＜0.01).
Conclusion: The MoCA test seemed to be more useful than the MMSE to detect mild cognitive impairment. However, bias from age and educational level might affect the test results like MMSE.
