Key Points

To update the position of the American Society for Stereotactic and Functional Neurosurgery on the use of MRgFUS for tremor management.
Reviewed literature on MRgFUS thalamotomy for tremors.
Evaluated safety and effectiveness for refractory essential tremor and Parkinson's disease tremor.
Considered long-term durability and early experiences with bilateral staged lesions.
MRgFUS thalamotomy is safe and effective for refractory essential tremor.
The technique also shows promise for Parkinson's disease tremor but raises concerns about long-term effectiveness.
Early bilateral staged applications indicate favorable outcomes.

Implication

Position update reports safe and effective tremor control in selected patients using MRgFUS intervention.

Abstract

MRgFUS thalamotomy is a safe, effective, and durable intervention for refractory ET in appropriately selected patients. The procedure appears to be safe and effective for PD tremor, although the long-term durability of the technique remains a concern. Early experience with bilateral staged lesions for ET suggests the procedure to be safe and effective.
