Any surgery that is performed on the nervous system, comprising the brain or spinal cord, is known as neurosurgery. Functional neurosurgery is a specific type of neurosurgery that aims to restore some neurological condition or function, or to treat a chronic neurological disorder that interferes with a person's day-to-day abilities or function. It entails precise surgical targeting of anatomical structures to modulate neurologic function. Functional neurosurgery covers a broad range of procedures that alter the functioning of the nervous system from the brain to peripheral nerves in the leg or arm. This can be achieved through a variety of methods including removing a seizure-causing part of the brain, utilizing an electrical stimulator on the spinal cord or brain to improve the symptoms of chronic pain or Parkinson's disease, or infusing medication directly into the spinal fluid. The success of any functional neurosurgical procedure depends on various factors such as constant monitoring, patient cooperation, as well as observation for early diagnosis and management of complications. This book explores all the important aspects of functional neurosurgery in the modern day. Different approaches, evaluations, and advanced studies on this topic have been included herein. The book will serve as a reference to a broad spectrum of readers.
