What is Dystonia? (Definition)
Dystonia is a neurological movement disorder in which sustained or repetitive muscle contractions result in twisting and repetitive movements or abnormal fixed postures. The movements may resemble those of a tremor. Dystonia is often intensified or exacerbated by physical activity, and symptoms may progress into adjacent muscles. There are several different forms of dystonia that may affect only one muscle, groups of muscles, or muscles throughout the body. Some forms of dystonia are genetic but the cause for the majority of cases is not known.
There is currently no cure for Dystonia. However, certain medications can be prescribed to lessen the severity of the symptoms. Also, physical therapy can help manage the muscle spasms that Dystonia may cause. Dystonia can start as slow repetitive movements and heighten to uncontrollable tremors. Dystonia can cause discomfort in performing daily tasks. It can also lead to functional blindness.
Symptoms for Dystonia can be different for every person. Focal Dystonia generally starts off occurring in the face, neck or arm. It can worsen for some people if fatigued, anxious or under stress. The cause of Dystonia is unknown. However, Dystonia can be a symptom of other diseases and conditions. Some of these include Parkinson’s disease, Huntington’s disease, Wilson’s disease, stroke, or from a birth injury.
