Inherited neurological disorder Huntington disease, also known as Huntington's chorea, is a hereditary, degenerative disorder of the central nervous system. Symptoms don't usually appear until mid-life (40s or 50s). There is a juvenile-onset form of Huntington's which affects people younger than 20 years old, but this form is more rare. Huntington disease is an inherited disorder. Many people with Huntington's have already had children by the time they are diagnosed. These children have a 50-50 chance of inheriting the gene for the disorder.
How the disease progresses
The degeneration of brain cells in Huntington disease starts out slowly. Early symptoms may include mood swings, depression, irritability, trouble driving, learning new things, remembering a fact, or making a decision. As the disorder continues, and more brain cells are destroyed, it becomes increasingly difficult for the person with Huntington's to concentrate on tasks, and he may have difficulty feeding himself and swallowing.
