What types of surgery are there to treat parkinson's disease?

Functional surgery: Usually surgery takes the form of deep brain stimulation (dbs) of the globus pallidus (gp), thalamus or subthalamic nucleus. Lesioning of the gp or thalamus is also done.

Deep Brain Stimulati: Deep brain stimulation is the primary surgical treatment for Parkinson's disease. This requires a commitment of time and medical fitness. Others may be eligible for a one-time brain lesion surgery.

Further Detail: Deep brain stimulation therapy of the stn (sub-thalamic nucleus) or gpi (globus pallidus interna) can greatly improve "on" time (good function with minimized symptoms) & greatly reduce dyskinesia (twisting, writhing, jerking movements during "on" time). Good candidates must be not demented, psychiatrically stable, & still demonstrating good symptom relief from meds, but with inconsistent results.
