Application of Montreal cognitive assessment scale in assessment of mild cognitive impairment

Objective To study the application of Chinese version Montreal cognitive assessment (MoCA) scale in assessment of mild cognitive impairment(MCI).Methods One hundred and twenty-eight MCI patients served as a MCI group and 101 healthy subjects served as a control group in this study.Their cognitive function was assessed according to the MoCA and MMSE scales.Results The total score on the MoCA scale was positively correlated with that on the MoCA scale in MCI group and control group(r=0.352,P0.05;r=0.765,P0.01).The score was significantly lower on the MoCA scale than on the MMSE scale(P0.01).The total score and other subitem scores on the MoCA scale were significantly lower in MCI group than in control group(P0.05).The sensitivity and specificity of MoCA and MMSE scales were 97.66% and 95.05%,32.03%and 100%,respectively,for the detection of MCI.Conclusion The total score on the MoCA scale is related with that on the MMSE scale in MCI patients and healthy subjects. The sensitivity of MoCA scale is higher than that of MMSE scale in assessment of MCI.
