How is chorea diagnosed?
Because so many conditions and disorders can cause chorea, your doctor will ask a range of questions about your family history, the medications you take, and any symptoms you’re having besides uncontrollable movements. Your doctor will also conduct a physical exam and ask how often and how long your uncontrolled muscle movements have been happening and whether they get worse during times of stress.
To determine the cause of chorea, your doctor may order:
- Blood tests to check for infections, lupus, thyroid levels or other endocrine or metabolic abnormalities.
- Imaging studies such as magnetic resonance imaging (MRI) scan or a computed tomography (CT) scan to look for changes in your brain.
- Genetic testing to see if you have the gene for Huntington’s disease.
How do I know if I have chorea?
If you have irregular muscle movements that you can’t control, you should see your doctor. Your risk of chorea is higher if you have an autoimmune disease, a family history of Huntington’s disease, or if you’ve had rheumatic fever.
