The field of Movement Disorders is one of the broadest and most complex in all of neurology. In addition to a wide spectrum of motor phenotypes, patients with movement disorders can also demonstrate a complex array of associated neurological and medical disturbances. Advances in all areas of clinical and basic neurosciences have had considerable impact on our understanding of etiology and pathogenesis of the broad spectrum of diseases of the nervous system that cause movement disorders. Advances in medical and surgical therapies have profoundly influenced the outcomes of many of these patients. In this textbook, Ashok Kumar along with 97 authors provide us an excellent overview of the remarkable complexity of this field. The 55 chapters deal with all movement disorder subtypes as well as a large number of overlapping themes such as basal ganglia models, imaging and movement disorder emergencies.
