Demographic and clinical correlates of MoCA-based PD-MCI classification in PD subjects with normal range MMSE scores. Mean values with standard deviation or percentages are given.
| PD without MCI (n=29) | PD-MCI (n=18) | Statistical significance | |
|---|---|---|---|
| Age (yr) | 66.6±7.9 | 65.4±7.8 | t=0.50, P=0.62 |
| Duration of motor disease (yr) | 5.8±3.4 | 6.1±4.0 | t=0.32 P=0.75 |
| Education (yr) | 15.5±2.7 | 14.7±2.5 | t=1.02, P=0.31 |
| Gender (males) | 22 (75.9%) | 18 (100%) | Yates’ χ2=3.38, P=0.066 |
| MMSE score | 29.5±0.7 | 28.9±1.2 | tapprox=1.85; P=0.076 |
| MDS-UPDRS Part I: Non-motor experiences of daily living | 7.24±4.45 | 6.67±6.30 | t=0.37, P=0.72 |
| MDS-UPDRS Part 2: Motor experiences of daily living | 8.21±6.43 | 9.11±6.68 | t=0.46, P=0.65 |
