Amyotrophic Lateral Sclerosis

Amyotrophic lateral sclerosis (ALS) is a fatal, neuromuscular disease that occurs when motor nerve cells cease to function and die. While a person's mind remains sharp and alert, voluntary muscle control is lost.

The ALS association is the only national nonprofit, voluntary health organization dedicated solely to the fight against ALS through research, patient support, information dissemination, and public awareness.
