We designed this book to address in a clear, comprehensive, and yet concise manner all of the key topics pertaining to use of DBS for clinicians. The First Edition of this book focused on the use of DBS to treat movement disorders and was extremely well received in the United States and internationally. The Second Edition provided updates and added dedicated chapters on the treatment of epilepsy and psychiatric disorders with DBS, as well as a new chapter focused on interventional MRI approaches to DBS lead implantation. In this new Third Edition, we've updated the content, included the latest information on new DBS devices, and expanded information on a broader scope of conditions that may benefit from treatment with DBS. We begin with a practical discussion of how to implement a DBS program. We then turn to surgical aspects, including new approaches to DBS lead implantation.

Finally, we end with a comprehensive discussion of troubleshooting"--
