TABLE 4.
Neuropsychological performance on Trails Test for PD patients and healthy controls.
| PD | Controls | p-value | ||
| Trails test | Speed non-inhibition condition (Trails 1 and 2) | 322.40 (192.84) | 187.2 (51.48) | 0.033 |
| Speed inhibition condition (Trails 3 and 4) | 472.2 (238.13) | 246.06 (56.53) | 0.003 | |
| Inhibition condition—Errors | 1.6 (1.35) | 0.30 (0.48) | 0.004 | |
| Inhibition condition—Accuracy | 95.46 (3.97) | 99.09 (1.32) | 0.004 | |
| Inhibition condition—Total executive score | 9.4 (4.83) | 15.91 (3.54) | 0.001 |
Means and standard deviations (in brackets) of type of errors (raw scores) and time to complete the task (in seconds) are provided. Accuracy, executive global score and p-values are also provided. Accuracy formula; Acc = (correct–incorrect/correct) × 100; Total Executive Score: Etotal = (correct–incorrect/speed) × 100.
