Huntington’s Disease Society of America
Huntington’s disease (HD) is a brain disease that is passed down in families from generation to generation. It is caused by a mistake in the DNA instructions that build our bodies and keep them running. HD causes deterioration in a person’s physical, mental, and emotional abilities, usually during their prime working years, and currently has no cure. The Huntington’s Disease Society of America (HDSA) is the premier nonprofit organization dedicated to improving the lives of everyone affected by Huntington’s disease.
