(Huntington Chorea; HD)
Huntington disease (HD) is a genetic problem of the brain. It causes the body to move in ways that the person cannot control. It also causes thinking problems that get worse over time.
HD is caused by a certain gene that does not work properly. All people who inherit this gene may get HD.
The chance of getting HD is higher in those who have people in their family who have it.
Problems often start between 30 to 50 years of age. They are mild at first and then get worse.
A person may have:
- Changes in eye movements
- Moving without control
- Jerking movements of the arms, legs, face, or belly
- Problems making decisions
- Lack of emotion
- Mood swings
- Problems walking and swallowing
The doctor will ask about symptoms and health history. The doctor may also ask if there are other people in the family who have HD. A physical exam will be done. Cognitive tests may also be done.
Blood tests will be done to look for the gene that causes HD.
Images may be taken to support the diagnosis. This can be done with:

There is no cure for HD. Symptoms can only be managed.
HD cannot be prevented in a person who has the gene that causes it.
