A Cochrane review published in 2016 reported moderate-quality evidence that a single Botulinum toxin-B treatment session could improve cervical dystonia symptoms by 10% to 20%, although with an increased risk of dry mouth and swallowing difficulties. [22] Another Cochrane review published in 2020 for Botulinum toxin-A found similar results. [23]

There are several types of torsion dystonia that affect different areas of the body. However, it is unknown if the gene that causes Early-onset torsion dystonia is responsible for the other dystonias as well. Cervical dystonia (spasmodic torticollis): A type of dystonia that affects the head, neck and spine. It can create problems by the ...
DBS is effective in treating primary generalized dystonia, and also used for focal dystonias such as cervical dystonia and task-specific dystonias (e.g., writer's cramp). In dystonia, marked effects can be reached by targeting the GPi using high frequency DBS, with large randomized trials demonstrating improvements of ~45% and significant ...
Botulinum toxin type-A is used to treat cervical dystonia, but it can become ineffective after a time. Botulinum toxin type B received FDA approval for treatment of cervical dystonia in December 2000. Brand names for botulinum toxin type-B include Myobloc in the United States and Neurobloc in the European Union. [139]

In musicians, the condition is called musician's focal dystonia, or simply, musician's dystonia. In sports, it may be involved in what is commonly referred to as the yips. The condition appears to be associated with ...
