Dystonia is a neurological movement disorder in which sustained muscle contractions cause twisting and repetitive movements or abnormal postures.The movements may resemble a tremor. Dystonia is often initiated or worsened by voluntary movements, and symptoms may “overflow” into adjacent muscles. treatment:Dopaminergic drugs - Levodopa (Sinemet, Madopar etc) Patients with the rare dopa-responsive dystonia (DRD) can find a dramatic, sustained improvement in their dystonia by taking small doses of levodopa. This condition is found primarily in dystonia affecting children or young adults. In these instances, a trial of levodopa is often proposed as an initial therapy by the physician. In cases of adult-onset dystonia, a physician is much less likely to propose levodopa for a patient unless there may be a history of early-onset dystonia in their family.
