There has been a major resurgence in stereotactic neurosurgery for the treatment of Parkinson’s disease and tremor in the past several years. More recently, interest has also been rekindled in stereotactic neurosurgery for the treatment of dystonia and other movement disorders. This is based on a large number of factors, which include recognized limitations of pharmacologic therapies for these conditions, better understanding of the functional neuroanatomy and neurophysiology of the basal ganglia, use of microelectrode recording techniques for lesion localization, improved brain imaging, improved brain lesioning techniques, the rapid emergence of deep brain stimulation technology, progress in neurotransplantation, better patient selection, and improved objective methods for the evaluation of surgical.
