The diagnostic subtype is important for the application of some types of treatments that target underlying etiological mechanisms and substantially modify the course of the disease Table 3. The many different clinical manifestations are classified according to four dimensions Table 1 including the region of the body affected, the age at onset, temporal aspects, and whether there are associated clinical problems. Organization Internet address American Dystonia Society dystoniasociety. The diagnostic challenge of primary dystonia: Augmenting dopamine transmission with levodopa is dramatically effective in dopa-responsive dystonia, which is most often caused by mutations in the GCH1 gene encoding the enzyme GTP-cyclohydrolase.

Expert Opin Ther Targets. Dopamine-related drugs Medications that augment or suppress dopaminergic transmission in the basal dystknie may be extraordinarily helpful in select populations of patients with dystonia.

Because there are so many different clinical manifestations and causes of the dystonias, it is not feasible to devise a universal treatment algorithm for all subtypes that combines the various medical and surgical options outlined above. GABA-related drugs Another frequently prescribed group of medications is the benzodiazepines such as alprazolam, chlordiazepoxide, clonazepam, ifletype diazepam.

Dystonia in corticobasal degeneration: Selective peripheral denervation for spasmodic torticollis: In more severe cases dystonic movements appear as persistent odd postures or fixed deformities. Levodopa is also at tiletype partially effective in other disorders affecting dopamine synthesis that are caused by deficiency of tyrosine hydroxylase, sepiapterin reductase, and others.

Return visits also should be anticipated every 2—4 years for battery replacement. At the molecular level, multiple genes have been discovered for rare subtypes of dystonia, 89 and they are involved in diverse biochemical processes.

Dystonic movements are typically patterned, twisting, and may be tremulous.

Open in a separate window. Most of fipetype groups also provide informational brochures, newsletters and local patient support group meetings where patients can obtain new information. Can J Neurol Sci. This list is expected to continue to grow, as more is learned about the underlying causes for dystonia. Short-term variation persistent, action-specific, diurnal, paroxysmal. One is the ideal surgical target. The dystonias are a group of disorders defined by specific types of abnormal movements.


Even for the most common and readily diagnosed subtypes of dystonia such as cervical dystonia, filetyp mean time from onset of symptoms to diagnosis is 4—6 years. Effect of prolonged neck muscle vibration on lateral head tilt in severe spasmodic torticollis. Some remain flietype static, while others are progressive or intermittent. Therefore, there is still a role for ablative procedures in some circumstances.

Tetrabenazine for the treatment of hyperkinetic movement disorders: Experience with high dosages of anticholinergic and other drugs in the treatment of torsion dystonia. Mexiletine in the treatment of spasmodic torticollis. Enthusiasm for specific strategies also is blunted by concerns that some filetyep designs may be harmful.

Botulinum toxin injections for the treatment of spasmodic dysphonia.
