Ballism

About Ballism

General Information

• Hemiballism involves involuntary, violent movements on one side of the body. They are especially violent because they involve the muscles where the limbs attach to the body.
• The most common cause is stroke or tumor.

Symptoms

• The abnormal movements of ballism consist of involuntary hurling, irregular, frequently violent movements of the shoulder and arm while the patient is awake.

Treatment

• The early treatment of choice for ballism is medication to help regulate dopamine and other brain chemicals and processes that control movement and emotions.
• Since this disorder is frequently temporary, surgery is considered only if symptoms persist for two to three months, or if the movements are so violent they exhaust the patient.
• Stereotactic surgery allows doctors to pinpoint locations in the thalamus, the portion off the brain that relays sensory impulses, and create lesions that ease abnormal movements.

Outcome

• Results of surgery are satisfactory in 50 percent to 69 percent of patients.
