title: Case studies in movement disorders.
abstract: Six cases representing the most commonly encountered movement disorders-restless legs syndrome with periodic limb movements, tics, myoclonus, chorea, essential tremor, and cervical dystonia-are presented. Discussion of each case focuses on a practical approach to recognizing the important clinical features of each movement disorder as well as the current therapeutic options. A detailed discussion of botulinum toxin follows the case on cervical dystonia, focusing on its mechanism of action, clinical indications, side effects, and dosing.
