[Neurosurgical treatment of dystonia].

In this review, we present evidence of treatment effect with deep brain stimulation (DBS) in patients with isolated forms of dystonia with generalised-, segmental- and focal phenotypes as well as tardive dystonia and dyskinetic cerebral palsy. Dystonia is a heterogeneous movement disorder, which can be disabling and difficult to treat. Patients with dystonia, who do not experience relief with medication and botulinum toxin, may be candidates for DBS.
