Brief Summary:

The proposed study is to evaluate the safety and initial effectiveness of the ExAblate Transcranial MRgFUS) treatment of patients with L-dopa induced dyskinesia of Parkinson's disease (LID PD).

Safety:

To evaluate the incidence and severity of adverse events associated with ExAblate Transcranial 4000 MRgFUS treatment of dyskinesia of Parkinson's disease.

Effectiveness:

To determine the level of effectiveness of the ExAblate Transcranial MRgFUS treatment of LID in PD patients. Efficacy will be determined utilizing clinical rating scales for dyskinesia (UPDRS-IV and the Unified Dyskinesia Rating Scale) from examinations at Baseline, 3-Months and 12-Months post-ExAblate treatment.
