CERVICAL DYSTONIA : A CURRENT REVIEW

Cervical dystonia is a movement disorder and the most common form of focal dystonia, presents with sustained neck spasms, abnormal head posture, head tremor, and pain. One of the interesting and unique features of cervical dystonia is the geste antagoniste. There is not a well-clear pathophysiology for cervical dystonia, but several studies report involvement at the central and peripheral level. Although oral drug therapy has limited efficacy in the treatment of patients with cervical dystonia, botulinum toxin serotype A and B has satisfactory benefits. Surgery is an option when other treatments fail or become ineffective.
