About Huntington's Disease

Huntington's disease is a brain disorder that is typically hereditary -- only 1 percent to 3 percent of cases develop without any family history. The disease is caused by a defect in a gene on chromosome number 4. This gene is known as the Huntington disease (HD) gene.
 
Huntington's disease can cause a number of physical, mental, and emotional problems. For example, early symptoms include:
 
 
Intellectual tasks often become more difficult as the condition progresses.
 
A genetic test is available to make or confirm a diagnosis of Huntington's disease. The same genetic test is also available as a screening procedure, which allows people to be tested even if they have no symptoms.
 
At this time, there is no cure for Huntington's disease. Treatment focuses on managing the symptoms.
