Huntington's chorea is a symptom of Huntington's disease, an inherited neurological disease that causes a progressive degeneration of nerve cells in the brain, affecting cognitive and physical ability. Chorea is the term for the involuntary, random, and jerky movements that are characteristic symptoms of Huntington's disease. 

There is no cure for Huntington's disease, but symptoms such as chorea may be treated with physical therapy, occupational therapy, and medication. The only drug approved for treatment of chorea by the FDA is a monoamine depletor called Xenazine (tetrabenazine). 

Certain other medications such as anxiolytics, benzodiazepines may also be prescribed to suppress chorea. Antipsychotics, mood stabilizers, and antidepressants may also be used to treat other symptoms of Huntington's disease.
