The Value Of Montreal Cognitive Assessment (MoCA) In Identifying The Patients With Vascular Cognitive Impairment

Objective:To determine the value of montreal cognitive assessment (MoCA) in identifying the patients with vascular cognitive impairment after stroke, and compare its results with those of mini-mental state examination(MMSE).Methods:MoCA and MMSE were performed on 30 patients,15 with vascular cognitive and 15 with non vascular cognitive.Results:Significant differences (P<0.05) are found both of MoCA and MMSE between case group and the control group. Significant differences(P<0.05) in each sub items of MoCA are found between case group and the control group, except denomination, memory and abstract ability. The initial optimal cut-off-point of MoCA was 18 in identifying VD, MoCA can provided a sensitivity of 86.70%, and a specificity of 73.30%, respectively, for screening VD, which was much better than MMSE(sensitivity 60.0% and specificity 93.3%)Conclusions:The initial optimal cut-off-point of MoCA is 18 in identifying VD by MoCA having high sensitivity and specificity.MoCA is a vivid screening scale in screening VD; however, MMSE shows poor sensitivity in screening VD, cannot be a reliable instrument in screening VD.
