Mean global and hemispheric cortical thickness between patients with Parkinson disease with and without mild cognitive impairment
| Cortical Thicknessa | PD-NCI (Mean) (SD) | PD-MCI (Mean) (SD) | Adjusted P Value |
|---|---|---|---|
| Left hemisphere | 2.20 (0.10) | 2.13 (0.11) | .095b |
| Right hemisphere | 2.19 (0.10) | 2.13 (0.10) | .264b |
| Global mean cortical thickness | 4.40 (0.19) | 4.26 (0.21) | .151b |
