Written by renowned authorities in the field, Deep Brain Stimulation in Neurological and Psychiatric Disorders discusses today's most current and cutting-edge applications of DBS. Initially used to treat Parkinson's disease and essential tremor, DBS now has new clinical indications, new anatomic targets, and new technologies that enable an expanded role for DBS in the treatment of other movement disorders such as dystonia, and for other neurologic disorders such as epilepsy, Tourette syndrome and cluster headache. Early experience has also been reported for psychiatric syndromes, such as obsessive-compulsive disorder and depression. This important book begins with reviews of the functional anatomy and physiology of motor and nonmotor aspects of the basal ganglia and their connections which underlie the application of DBS to neurological and psychiatric disorders. This is followed by proposed mechanisms of action of DBS based on functional neuroimaging and neurophysiologic studies in animals and man.
