Dystonia is often initiated or worsened by voluntary action and associated with overflow muscle activation. This strategy also is untenable, because recent progress in dystonia research has led to a long list of treatable disorders that grows every year Table 3.

Experience with high dosages of anticholinergic and other drugs in the treatment of torsion dystonia. However, depletion of dopamine with tetrabenazine does not carry these same risks, and it may be useful for some patients with dystonia, particularly those with tardive dystonia.
For cervical dystonia the most common side effects are dysphagia, excessive neck muscle weakness, and occasionally dry mouth. When a specific etiology cannot be determined, it is important to follow patients and revise the diagnosis as additional clinical features are recognized.
Table 4 provides a summary of some internet sites where information is regularly updated, and other educational and research opportunities are available to patients. dstonie
For laryngeal dystonias the most common side effects are hoarsenss or hypophonia, and rarely dysphagia and aspiration. Educating patients about the most reliable online sources of information can help to avoid misunderstandings.
Effective doses range from 6—40 mg daily, divided across 3—4 doses. For blepharospasm the most common side effects are ptosis, local hematoma formation, tearing, and rarely blurry vision or diplopia.

filftype Return visits also should be anticipated every 2—4 years for battery replacement. GABA-related drugs Another frequently prescribed group of medications is the benzodiazepines such as alprazolam, chlordiazepoxide, clonazepam, and diazepam.
Clinical variants of idiopathic torsion dystonia. Education and counseling Education and counseling are important for several reasons. Their safety and efficacy have been the subject of multiple dystonke summaries, including several systematic evidence based reviews.
Ablative procedures may be useful in developing countries where the cost of equipment for neuromodulation and requirements for regular follow-up are prohibitive.
Multiple surgical interventions are available for the treatment of the dystonias. National Center for Biotechnology InformationU. Neuromodulation of the brain and peripheral surgeries that target nerve or muscles can also be very useful when more conservative methods fail.
Dystonia as a network disorder: Patients with isolated focal and segmental dystonias also appear to respond well to neuromodulation, although perhaps less predictably than those with isolated generalized dystonia.
Medications that augment or suppress dopaminergic transmission in the basal ganglia may be extraordinarily helpful in select populations of patients with dystonia. However, neuromodulation has its own risk of complications related to the hardware, and it is expensive.

Psychiatric comorbidities in dystonia: Clinical, etiological, and therapeutic features of jaw-opening and jaw-closing oromandibular dystonias: If a cause can be identified, specific etiology-based treatments may be available.
Some dystonias have no apparent pathology in the nervous system, while others are associated with defects dystojie can be detected by neuroimaging or post-mortem histopathological studies.
