Magnetic resonance–guided focused ultrasound for the management of tremor: update on the position statement of the American Society for Stereotactic and Functional Neurosurgery

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.
