A panel of highly experienced neurosurgeons, neurophysiologists, neuropsychologists, and neuroanatomists join forces to create an integrated, cutting-edge survey all of the methodologies necessary for successful surgical treatment. On the surgical side they review a variety of techniques for Parkinson's disease, including thalamotomy, pallidotomy and bilateral pallidotomy, subthalamotomy, pallidal and thalamic deep brain stimulation, and subthalmic deep brain stimulation. Surgical therapy for tremor and dystonia is also covered. On the patient side, the authors systematically examine the key issues involved in any surgical procedure: Patient selection, patient assessment before and after surgery, brain target localization, and postoperative programming of brain stimulators.
