Surgical options in Parkinson's disease.

Surgical treatments for Parkinson's disease (PD) have again become important adjuncts of care in these patients. We have learned much from the thousands of lesions performed historically, and are now advancing the entire field of movement disorder surgery to new levels of sophistication and understanding. The last 5 years have seen more precise and reliable lesioning and the arrival of multiple sites of intervention afforded by recent developments in deep brain stimulators. Because patients typically derive significant benefit in their quality of life from these procedures, while undergoing little risk, the surgical options should be carefully considered for selected PD patients.
