rTMS as an Intervention for Levodopa-induced Dyskinesia

Summary

The proposed study investigates the use of repetitive transcranial magnetic stimulation (rTMS) as a treatment for levodopa-induced dyskinesia (LID) in Parkinson's Disease (PD). Specifically, the study aims to determine whether patterned stimulation of the pre-supplementary motor area (pre-SMA) can delay the onset of LID after levodopa intake and reduce LID severity in PD patients. This study will provide critical insights into potential targets for rTMS treatment, optimal rTMS parameters, and the mechanisms underlying LID in Parkinson's disease.
