Chorea is a common symptom of Huntington's disease, causing patients to experience jerky, random and uncontrollable movements.
The condition can make independent living difficult for people with the disease and many struggle with day-to-day activities.
Patients are also at a greater risk of falling, which increases the chance of mortality among older adults.
Medications can help to mediate the problem, but not all are effective and some come with side effects.
New guidance released by the American Academy of Neurology recommends a series of drugs which are effective in treating Huntington's disease.
According to the experts, tetrabenazine, riluzole, amantadine and nabilone can be beneficial for addressing chorea. Howwever, riluzole, amantadine and nabilone are not often prescribed for the condition.
Dr Melissa Armstrong, lead author of the guideline, commented: "People with Huntington's disease who have chorea should discuss with their doctors whether treating chorea is a priority.
"Huntington's disease is complex with a wide range of sometimes severe symptoms and treating other symptoms may be a higher priority than treating chorea."
