Application of MoCA in the screening of MCI in elderly patients

[Objective]To explore the application of Montreal cognitive Assessment( MoCA) in the screening of mild cognitive impairment( MCI) in elderly patients.[Methods]A total of 56 MCI patients were selected as MCI group and 50 adults with normal cognition as control group. Their cognitive function was assessed according to the MoCA and MMSE scales. And the results were analyzed.[Results]The total score of MoCA was significantly lower than the total score of MMSE in MCI group and control group( P 0.01). The sensitivity and specificity of MoCA and MMSE were 96.4% and 84%,35.7% and 100%,respectively in MCI screening. The total MoCA and its sub-items were significantly different between the MCI group and the control group( P 0. 01),except for the fixed orientation( P 0. 01).[Conclusion]MoCA is a highly sensitive scale for MCI screening,which allows comprehensive assessment of the cognitive function of MCI patients,and it is more sensitive in screening MCI than MMSE.
