Can deep brain stimulation cure parkinson's disorder?

No, but very helpful: 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.

DBS & PD: Deep Brain Stimulation (DBS) can not cure Parkinson's Disease (PD). However, DBS can significantly help the symptoms such as tremor, rigidity & bradykinesia (slowness of movement). DBS does allow patients to significantly reduce the dosage or number of PD medications they are taking. DBS increases the quality of life in PD, however, patient selection is very important since it is not for everyone.
