Huntington’s disease is a fatal genetic disorder that causes the progressive breakdown of nerve cells in the brain. It deteriorates a person’s physical and mental abilities usually during their prime working years and has no cure. Every child of a parent with HD has a 50/50 chance of inheriting the faulty gene that causes the disease. Today, there are approximately 41,000 symptomatic Americans and more than 200,000 at-risk of inheriting the disease. Huntington’s disease is described as having ALS, Parkinson’s and Alzheimer’s – simultaneously. HD is characterized by a triad of symptoms, including progressive motor dysfunction, behavioral disturbance and cognitive decline.
