Life+Expectancy

There are few cases of Huntington's that start before the age of 20. This is very rare. Only about 10% of people experience Juvenile Huntingtons. It is more common for People with Huntingtons to start experiencing symptoms between the ages of 30 to 50. The life expectancy of people with Huntington's disease is around 20 years after the onset of the disease. There is no specific number of years a person has to live after experiencing symptoms. Every case of Huntingtons has its own progression rate. This is a reason why Huntingtons is dangerous because every case is different and people never know exactly how long they have to live.
