Using
TBSS, we investigated WM changes in 39 Parkinsons disease (PD) patients, 20 progressive
supranuclear palsy (PSP) patients (10 Richardsons syndrome [PSP-RS] and 10
PSP-Parkinsonism [PSP-P]), and 26 controls. PSP-RS showed the most pronounced
pattern of decreased FA, including both infratentorial and supratentorial
regions, vs. controls and other patient groups. A similar pattern of FA
decrease (except for superior cerebellar peduncle) was found in PSP-P vs.
controls and PD (only at a lower significance). Impaired WM integrity was
found in PSP but not in PD. The less prominent WM involvement in PSP-P might
be associated to its favorable clinical status.
