The book "Deep Brain Stimulation in Neurological and Psychiatric Disorders" offers a comprehensive analysis of chronic deep brain stimulation (DBS) and its application in neurotherapy. Since the introduction of DBS in the 1990s for the treatment of Parkinson's disease and essential tremors, the understanding and application of this technique have significantly evolved. The work highlights the various clinical indications, anatomical target structures, and technological advancements that have expanded the use of DBS in other movement disorders such as dystonia and Tourette syndrome, as well as neurological conditions like epilepsy and cluster headaches. Furthermore, it addresses the limited but growing experience with DBS in psychiatric syndromes such as obsessive-compulsive disorder and depression. Given the increasing application of DBS in neurology and psychiatry, this book is a valuable resource for professionals seeking to stay informed about the latest scientific findings, treatment methods, and technologies.
