A condition characterized by focal DYSTONIA that progresses to involuntary spasmodic contractions of the muscles of the legs, trunk, arms, and face; The hands are often spared, however, sustained axial and limb contractions may lead to a state where the body is grossly contorted; Onset is usually in the first or second decade; Familial patterns of inheritance, primarily autosomal dominant with incomplete pentrance, have been identified; --------------(Adams et al;, Principles of Neurology, 6th ed)------------------

Primary dystonia accounts for 90% of cases; Primary dystonias with onset in childhood have previously been termed dystonia musculorum deformans; Childhood-onset dystonias are often inherited, usually in an autosomal dominant pattern; about half of adult-onset cases seem to have a genetic basis; Spontaneous genetic mutation then hereditary evidence with progeny is seen; occasionally there is no answer but more often dominant autosome loci; there are about 13 different clinial syndromes and about 8 gene loci shown; Occasionally, a specific and potentially treatable cause of dystonia can be identified; One of the most important examples is Wilson"s disease ; neurologic symptoms are the initial manifestations in about 50% of patients with this autosomal recessive disorder, which appears during the second or third decade; Tardive dystonia is a persistent form of dystonia caused by exposure to dopamine receptor-blocking drugs such as major tranquilizers (eg, chlorpromazine, thioridazine, fluphenazine, thiothixene, haloperidol, loxapine, amoxapine) and certain antiemetics (eg, prochlorperazine, metoclopramide) ; Levodopa can also cause intermittent dystonia (and focal dystonia may be the initial symptom of Parkinson"s disease); In all drug-induced dystonias, the offending drug should be withdrawn or the dosage reduced if possible; In contrast to focal, segmental, or generalized dystonia, hemidystonia is associated with an identifiable cause in most cases, including subcortical infarction, arteriovenous malformation, abscess, tumor, and other lesions, some of which can be treated surgically; Many other causes of secondary dystonia are possible, but only a few are amenable to therapy; Patients who are socially and occupationally disabled by dystonia despite optimal medical therapy, including botulinum toxin, can sometimes be helped surgically; Surgical procedures include orbicularis myectomy for blepharospasm, cervical rhizotomy for neck dystonia, and thalamotomy, pallidotomy, or deep brain stimulation of the subthalamic nucleus or pallidum for hemidystonia or generalized (predominantly distal) dystonia; Such procedures are effective in most patients but are associated with both potentially serious complications and high rates of symptom recurrence, thus making them a last resort
