| EPD | MPD | PDD | Total | |
|---|---|---|---|---|
| EPD | 18 (75%) | 5 (20.8%) | 1 (4.2%) | 24 (100%) |
| MPD | 6 (33.3%) | 7 (38.9%) | 5 (27.8%) | 18 (100%) |
| PDD | 0 | 3 (20%) | 12 (80%) | 15 (100%) |
Discriminant analysis with a leave-one-out cross validation test for the mean volume of the left hippocampus, and the cortical thickness of the left temporal pole, left entorhinal cortex, right hippocampus, right superior frontal, right posterior cingulate, right inferior temporal, right parahippocampal and right isthmus cingulate. Values in parentheses refer to the percentage of subjects correctly identified using the above measures.
EPD, early Parkinson's disease; MPD, moderate Parkinson's disease; PDD, Parkinson's disease with dementia.
