Huntington's Disease Statistics
In general, the duration of Huntington's disease ranges from 10 to 30 years. The most common causes of death are infection (most often pneumonia), injuries related to a fall, or other complications.
Adult-onset Huntington disease, the most common form of this disorder, usually begins in middle age. Individuals with this form of Huntington disease generally survive about 15 to 25 years after onset.
There is also an early-onset form of Huntington disease that begins in childhood or adolescence.
Seizures occur in 30 to 50 percent of individuals with this condition. The course of early-onset Huntington disease may be shorter than adult-onset Huntington disease; affected individuals generally survive 10 to 15 years after onset.
