Functional neurosurgery for movement disorders has evolved considerably in recent years. Many patients with a variety of symptoms enjoy significantly improved quality of life with minimal side effects. There are now more treat-ment options for patients suffering with advanced PD, ET, cerebellar tre-mor, dystonia, and spasticity, and even more promising therapies are on the horizon. Nevertheless, surgical therapies for movement disorders as a whole still do not yet meet evidence-based standards. Further studies are essential in order to clarify the surgical targets and techniques that are opti-mally suited to treat patients with each of these devastating conditions.
