Initially performed only at academic centers, over the past decade it has become a widespread surgical procedure. A variety of surgical techniques are employed and innovations are introduced frequently. This book is an ideal source of information for the many practicing neurosurgeons who did not learn this surgery during their training but would now like to add it to their practice, as well as an excellent update on exciting new developments in surgery for Parkinson disease. This book is designed to provide practicing neurosurgeons with current knowledge on the practical aspects of surgical treatment of patients with Parkinson disease. It explains how to identify surgical candidates and determine the optimal surgery, describes the various surgical techniques that are currently employed, and offers insights into how to optimize deep brain stimulation therapy after implantation. The keys to avoidance of surgical complications are carefully elucidated. In addition, an overview is provided of potential advances on the near-term horizon, including closed-loop deep brain stimulation, gene therapy, and optogenetics. All topics are covered by experienced Parkinson disease surgeons, in a concise and digestable format.  The book will be an ideal source of information for the many practicing neurosurgeons who would like to add deep brain stimulation to their practice, as well as an excellent update on new developments in surgery for Parkinson disease.
