Prominent neurologists and movement disorders experts from around the world logically and systematically review the major movement disorder emergencies, instructing the reader on how optimally to recognize and manage these problems. The authors comprehensively cover a broad range of disorders, including acute dystonic reactions, neuroleptic malignant syndrome, startle syndromes, and tic emergencies, and stress the importance of certain obvious diagnoses such as Wilson's disease, dopa-responsive dystonia, and Whipple's disease, in which delayed diagnosis in less emergent situations can lead to slowly evolving and often irreversible neurologic damage with tragic consequences. Patient vignettes at the beginning of each chapter focus the reader's attention and highlight the urgency of the problem.
