1. INTRODUCTION
From Parkinson’s disease (PD) to dystonia, movement disorders are major neurologic causes of disability, causing not only physical handicap, but often social embarrassment as well. Although a plethora of pharmacologic options exists to treat these disorders, many limitations unfortunately remain. Functional neurosurgery now has the ability to reduce the severity of symptoms and improve the quality of life for patients with these devastating neurological disorders.
