| Patient Group | Substantia Innominata Thickness (mm) |
|---|---|
| Elderly control subjects (n = 21) | 2.57 ± 0.19 |
| AD (n = 39) | 1.78 ± 0.28* |
| Vascular dementia (n = 23) | 1.94 ± 0.22* |
| Frontotemporal dementia (n = 5) | 1.79 ± 0.38* |
| Parkinson disease with dementia (n = 8) | 1.93 ± 0.19* |
* P < .0001, compared with thickness in elderly control subjects.
