| Lower | Upper | |||
| MoCA-B (per point increase) | 0.697 | 0.513 | 0.947 | 0.021 |
| Hippocampal Ktrans (per 1 × 10−3 min−1 unit) | 0.837 | 0.540 | 1.296 | 0.424 |
| Thalamic Ktrans (per 1 × 10−3 min−1 unit) | 1.502 | 0.761 | 2.964 | 0.241 |
| Hippocampal Volume (per cm3 unit) | 0.322 | 0.105 | 0.992 | 0.048 |
