DBS Surgery Usually Helps With ...
Most patients with Essential Tremor have reduced, minimal or no tremor with DBS. Medication is reduced or eliminated.
Parkinson's Disease patients have significant improvement with tremor, rigidity, akinesia, bradykinesia.
Intraoperative Testing of Patient with Esential Tremor
As the surgeon threads the electrode into place, watch this Essential Tremor patient's hand tremor almost stop when the electrode reaches target. This is called a "thalamotomy effect". Also notice that the patient is awake and fairly comfortable during the procedure. With the electrode in place, testing is done with different stimulation settings. After testing, one can see that the patient now has good tremor control with the current stimulation settings.
Intraoperative Testing of Patient with Parkinson's Disease
This Parkinson patient has severe tremor and rigidity. Watch the change in his hand control when we find the optimal settings while testing the electrode stimulation during surgery.
