The Huntington's Disease Society of America: Dedicated to Education and Care
November 01, 2006
Huntington disease (HD) is a devastating hereditary, degenerative brain disorder for which there is, at present, no effective treatment or cure. More than a quarter of a million Americans have HD or are at risk for the disease because of potential genetic transmission. The disease slowly diminishes the affected person's ability to walk, think, talk, and reason. As it progresses, concentration and short-term memory diminish and involuntary movements of the head, trunk, and limbs increase.
