About Huntington's Disease
Huntington's disease (HD) is a genetic, degenerative brain disorder that causes uncontrolled movements, loss of ability to think and reason, and severe emotional disturbances. People with HD eventually become dependent on others for their care. The onset of the disease is typically between the ages of 30 and 50.
Age of Onset
The onset of HD typically strikes individuals during their most productive adult years, between the ages of 30 and 50, but may appear as early as the age of two or as late as the age of 70. Even within a single family the onset age of symptoms and the type of symptoms at onset may vary from one person to another .
More than a quarter million Americans are at risk of inheriting HD from an affected parent. An individual who inherits the gene mutation will develop the disease. HD does not skip generations. It affects all races and ethnic groups and both sexes. Each child of an HD-affected parent has a 50 percent chance of inheriting the disorder.
The HD gene was isolated in 1993. Since then, research continues to accelerate our understanding of the disease. UC San Diego Health connects people to active clinical trials studying ways to treat HD with medications and to assess disease progression.
