While there are several comprehensive textbooks on movement disorders, all are lengthy, thick, hardbound books and thus are less useful for the busy, practicing clinician who often needs a quick guide on the diagnostic approach and therapy for various movement disorders. There are a few practical, therapeutic handbooks on Parkinson disease but there are none for other types of movement disorders (chorea, dystonia, myoclonus, ataxia, etc). The ever busy clinician will also benefit from a “primer” on DBS—its new device types, indications, identification of ideal and non-ideal candidates, and trouble-shooting. This third edition is a practical yet authoritative guide to the diagnosis and work up, and the pharmacological, non-pharmacological and surgical treatments of all types of movement disorders for the clinician-intraining and the practicing clinician. The authors used an “expanded outline bullet point” format, with liberal use of flow charts, algorithms and tables, with emphasis on clinical presentation, work-up and management, rather than pathophysiology and disease mechanism. In summary, this book should provide a comprehensive and practical approach to the neurological, behavioral, and surgical treatment of movement disorders. Because the authors anticipate that clinicians may be reading this book comprehensively, from start to finish; or, using it “on demand” by quickly surveying specific chapters related to the phenomenology of a challenging patient—content overlap has been intentional, to emphasize concepts and principles in diagnosis and management. Several movement disorders can present with different phenomenologies, thus several disorders will reappear in various chapters. From the first to this latest edition, the authors aim has always been to empower the modern clinician with the necessary skills in making the evaluation of movement disorders less intimidating and more rewarding.
