What is Huntington's Disease?

Huntington's disease is a rare condition that causes parts of the brain to break down, or degenerate. It is also called Huntington's chorea. The disease causes rapid, jerky body movements and the loss of normal mental abilities (dementia). Huntington's disease can cause personality changes, behavior problems, and memory loss. Symptoms usually develop after age 40. There is no known cure. But treatment with medicines may help control the involuntary movements and behavior changes.

Huntington's disease is caused by a changed, or mutated, gene. If you have a parent with the disease, you have a 50% chance of getting the changed gene and the disease. But there is no way to know when you will develop Huntington's disease. Some people may pass on the changed gene to a child before knowing that they have the changed gene.
