Prognosis



Huntington's disease causes disability that worsens over time. Persons with this disease usually die within 15 to 20 years of proper diagnosis. The cause of death is often infection, although suicide is also common.

It is important to realize that the disease affects everyone differently. Persons with Huntington's disease may have mild abnormal movements later in life and slow disease progression, while others may be severely affected at a young age.
