Surgery should be considered for patients with disabling essential tremor that is not adequately controlled with drug therapy or externation neuromodulation devices.
The four proven surgical treatments are:
- Stereotactic thalamotomy
- Chronic thalamic deep brain stimulation (DBS)
- Focused Ultrasound (FUS)
- Gamma-knife surgery (GKS)
Each of these procedures allow patients to potentially reduce their tremor medications.
