The relation between hippocampal DTI parameters and global verbal memory performance in participants with low and normal hippocampal volume
| Hippocampus | ||||||

| MD | FA | MD | FA | MD | FA | |
| Global verbal memory performance | ||||||
| Low‐hippocampal volume (n = 166) | −0.20 (0.044) | 0.11 (0.169) | −0.13 (0.162) | 0.03 (0.706) | −0.19 (0.073) | 0.07 (0.368) |
| Normal hippocampal volume (n = 333) | −0.15 (0.020) | 0.08 (0.108) | −0.24 (<0.001) | 0.05 (0.390) | −0.21 (0.002) | 0.07 (0.194) |
Numbers represent regression coefficients standardized beta's (P values), adjusted for age, sex, educational level, depressive symptoms, hippocampal, and WML volume and the presence of lacunar infarcts.
Low‐hippocampal volume is defined as the lowest tertile of the hippocampal volume distribution; normal hippocampal volume is defined as the upper two tertiles of the hippocampal volume distribution.
