What Is Huntington's Disease? What Causes Huntington's Disease?

Huntington's disease is an incurable, hereditary brain disorder. It is a devastating brain disorder for which there is no currently 'effective' treatment. Nerve cells become damaged, causing various parts of the brain to deteriorate. The disease affects movement, behavior and cognition - the affected individuals' abilities to walk, think, reason and talk are gradually eroded to such a point that they eventually become entirely reliant on other people for their care.
