Chorea treatment
Huntington's was given different names throughout this history as understanding of the disease changed. Originally called simply 'chorea' for the jerky dancelike movements associated with the disease, HD has also been called 'hereditary chorea' and 'chronic progressive chorea'.
In August 2008 the U.S. Food and Drug Administration approved tetrabenazine to treat Huntington's chorea, making it the first drug approved for use in the United States to treat the disease. Antipsychotic drugs, such as haloperidol, or other drugs, such as clonazepam, may help to alleviate choreic movements and may also be used to help control hallucinations, delusions, and violent outbursts.
These medications may also have severe side effects, including sedation, and for that reason should be used in the lowest possible doses.
