Coordinates of the between-group differences in diffusion tensor measures
| Diffusion measures | Geometrical centre and extension of the cluster | Pathway/region | Cluster size | MNI coordinates | t* | ||

| FA | Patients < controls | Left superior longitudinal tract (parietal pars) extended to fibres of the inferior longitudinal fasciculus and inferior fronto-occipital fasciculus | 512 | −43 | −42 | 15 | 4.49 |
| MD | Patients > controls | Fornix extended to bilateral anterior thalamic radiations | 266 | 0 | −7 | 11 | 4.92 |
FA = fractional anisotropy; MD = mean diffusivity; MNI = Montreal Neurological Institute.
