The CMMSE (17) and CDR (12) were used as a measure of global cognitive function.
subjects with a CMMSE score [greater than or equal to] 75th percentile (CMMSE [greater than or equal to] 28) were compared with those at the 25th percentile (CMMSE of 20-24); and
subjects with a CMMSE score [greater than or equal to] 90th percentile (CMMSE [greater than or equal to] 29) were compared with those at the 10th percentile (CMMSE of 20-22).
The most important limitation of this analysis was the profound effect of education on CMMSE. Currently, our definition of high cognitive function has been limited to elderly subjects with CMMSE scores at or above the upper end of the sample in a cross-sectional study.
The mean (SD) CMMSE score was 27.5 (1.6) and the mean (SD) CGDS score was 1.9 (1.9).
This could be explained by the fact that the eligibility criteria of CMMSE score of [greater than or equal to] 25 excluded a considerable number of elderly who had a below-mean CMMSE score (19) and that females were more active participants in community activities.
Their mean (SD) CMMSE score was 28 (2), significantly higher than that in the CD group (t = -7.4, p < 0.001).
Age, CMMSE score, ADAS-Cog total score, 10-minute delayed recall and CVFT scores yielded significant correlations with all MacCAT-T summary scores.
The Appreciation score was significantly predicted by the CMMSE score ([beta] = 0.6, p < 0.001) and the relationship accounted for about 39% of the variance.
