People with chorea have irregular, uncontrollable movements that can happen in many areas of the body. Patients with chorea may have:
- Muscle contractions with no regular rhythm
- Difficulty swallowing
- Difficulty talking
- Abnormal walk
Causes and Risk Factors
Chorea has multiple known causes.
Chorea is a common symptom of Huntington’s disease.
Rheumatic fever can cause chorea. In this case, it is called Syndenham's chorea. If the condition is caused by pregnancy, it is known as chorea gravidarum. Other causes include medications, endocrine disorders, or a stroke or tumor.
A rare form of chorea has been linked to high levels of a certain protein known as alpha-fetoprotein. This increased protein level can be associated with ataxia-teleangectasia, a genetic condition.
