Progressive Sopranuclear Palsy (PSP) is a degenerative parkinsonism clinically characterized by postural instability and sopranuclear gaze palsy. Repetitive Transcranial Magnetic Stimulation (rTMS) shows promising results when used as a therapeutic tool. We investigated the impact of cerebellar iTBS on Functional Connectivity (FC) in a group of PSP patients comparing Resting State fMRI, before and after iTBS treatment.We found a bilateral increase in FC in the caudate nucleus and in left parietal cortex, and a FC reduction in the right precuneus, after iTBS treatment. Our study provides new evidence that iTBS is able to induce modifications of FC in PSP patients.
