Craniofacial Dystonia is a condition characterized by involuntary, slow and repetitive muscle spasms or contractions in the head, face, and neck areas. Examples include uncontrollable eye blinking, or the neck straining toward one side of the body. The contractions can range from mild to severe enough to affect quality of life. The exact cause of craniofacial dystonia is unknown, but medical issues that affect the brain and nerves, such as certain genetic conditions, a stroke, infection or tumor, can often be the underlying cause of symptoms. One should visit a physician if the symptoms are unexplained, or if they become worse. Physicians will usually test for potential causes using blood tests, urine tests, genetic tests and medical imaging. There is no cure for craniofacial dystonia, but physical therapy, muscle-relaxing activities like yoga and meditation, and certain medications may improve symptoms.
