Chorea is usually a symptom of other movement disorders, especially Huntington's disease. It causes muscle movements that you can't control in your arms, legs, and face.
Chorea comes from the Greek word that means "to dance" and this symptom can make you look like you're dancing. Although it can happen on its own, it's usually a sign of another condition.
Symptoms of chorea include:
- Muscle movements you can't control in your arms, legs, and face. These may look like fidgeting, jerking, or twisting your muscles.
- Changes to your grip, such as gripping and releasing your fingers repeatedly
- Moving your tongue in and out of your mouth without realizing
