| Group | Present, n (%) | Absent, n (%) |
|---|---|---|
| * “Absence” is defined as having a medial temporal lobe atrophy (MTA) score ≤1 on both sides, and “presence” is defined as having an MTA score ≥2 for either side. Kruskal–Wallis test, p < 0.001. Post hoc Fisher’s exact test showed significant differences between all dementia groups and Con (p < 0.001), and between AD and DLB (p < 0.001). | ||
| VaD = vascular dementia; DLB = dementia with Lewy bodies. | ||
| AD | 28 (100) | 0 (0) |
| VaD | 21 (87.5) | 3 (12.5) |
