What is Huntington's Disease?
Huntington’s disease is a hereditary condition in which your brain’s nerve cells gradually break down. This affects your physical movements, emotions, and cognitive abilities. There is no cure, but there are ways to cope with this disease and its symptoms.
Huntington’s disease is much more common in people with European ancestry, affecting about three to seven out of every 100,000 people of European descent.
People that have (had) Huntington's Disease
- Woody Guthrie

What are some Symptoms of Huntington's Disease?
- trouble making decisions
- difficulty understanding new information
- poor coordination
- minor involuntary movements
- uncontrolled twitching movements, called chorea
- difficulty walking
- trouble swallowing and speaking
- memory loss
- personality changes
- speech changes
- decline in cognitive abilities
An increase in the size of the CAG segment leads to the production of an abnormally long version of the huntingtin protein. The elongated protein is cut into smaller, toxic fragments that bind together and accumulate in neurons, disrupting the normal functions of these cells. The dysfunction and eventual death of neurons in certain areas of the brain underlie the signs and symptoms of Huntington disease.
Type of Mutation
Mutations in the HTT gene cause Huntington disease. The HTT gene provides instructions for making a protein called huntingtin. Although the function of this protein is unknown, it appears to play an important role in nerve cells (neurons) in the brain.

What is the long-term outlook fot Huntington's Disease
There is no way to stop this disease from progressing. The rate of progression differs for each person and depends on the number of genetic repeats present in your genes. A lower number usually means that the disease will progress more slowly.
Causes of death include:
- complications from being unable to swallow
- injuries from falling
- infections, such as pneumonia
