Individual results may vary. Xenazine may not be effective in reducing choreic movements in all HD patients. Please review the Important Safety Information, including Boxed Warning about the increased risk of depression and suicidality, below.
Huntington's disease (HD) is often diagnosed by a specialist (for example, a neurologist) after a complete neurological examination, a review of you and your loved one's family history, and may include brain imaging and genetic testing.2
Brain imaging tests can include computed tomography (CT) scan and magnetic resonance imaging (MRI).2
Thanks to the discovery of the HD gene in 1993, doctors can now use genetic testing to confirm if a person has HD.2
- Even before symptoms appear, pre-symptomatic genetic testing can help diagnose HD in individuals who have HD in their family but don’t show symptoms yet.2
- If there is an unknown or negative family history, genetic testing helps a person who is showing symptoms of the disease know if they have the HD gene.2
Before having a genetic test, it is important that you and your loved ones are prepared for how you will feel after the results are known. It’s important to learn as much as you can about the disease from your doctor and other healthcare professionals.
