What Is It?

Huntington's disease causes nerve cells in the brain to stop working properly. It leads to mental deterioration and loss of control over major muscle movements.

Huntington's disease worsens over time. It is an inherited (genetic) disease. Each child of a parent with Huntington's disease has a 50% chance of inheriting the illness.

Huntington's disease is relatively uncommon. It affects people from all ethnic groups. The disease affects males and females equally.
