It is a movement disorder in which a person's muscles contract uncontrollably. The contraction causes the affected body part to twist involuntarily, resulting in repetitive movements or abnormal postures. Dystonia can affect one muscle, a muscle group, or the entire body.
Some early symptoms include: • A "dragging leg" • Cramping of the foot • Involuntary pulling of the neck • Uncontrollable blinking • Speech difficulties Dystonia seems to be related to a problem in the basal ganglia. That's the area of the brain that is responsible for initiating muscle contractions. The problem involves the way the nerve cells communicate
Surgery to cut the nerves leading to muscles affected by dystonia or removing the muscles may help reduce muscle contractions. In addition, surgery to destroy the small area within the brain that dystonia occurs from may stop or reduce the disorder
