What this trial studies

This registry aims to gather long-term safety and effectiveness data on unilateral thalamotomy performed using the Exablate Neuro system for patients with medication-refractory tremor dominant Parkinson's Disease. Participants will have undergone the procedure prior to enrollment and will be monitored for various clinical outcomes over a period of five years. Data collected will include adverse events, medication usage, and clinical rating scales to assess tremor severity and quality of life. The study is designed to provide insights into the long-term impact of this treatment approach.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 30 years and older who are undergoing an Exablate procedure for tremor dominant Parkinson's Disease.

Not a fit: Patients who do not agree to participate or are unlikely to complete the study will not benefit from this registry.

Why it matters

Potential benefit: If successful, this registry could provide valuable information on the long-term safety and effectiveness of thalamotomy, potentially improving treatment options for patients with Parkinson's disease.

How similar studies have performed: Other studies on thalamotomy for Parkinson's disease have shown promising results, indicating that this approach is supported by prior evidence.
