ALS


Amyotrophic Lateral Sclerosis

ALS (Amyotrophic Lateral Sclerosis), also known as Lou Gehrig's Disease, is an incurable fatal neuromuscular disease characterized by progressive muscle weakness, resulting in paralysis. The disease attacks nerve cells in the brain and spinal cord. Motor neurons, which control the movement of voluntary muscles, deteriorate and eventually die. When the motor neurons die, the brain can no longer initiate and control muscle movement. Because muscles no longer receive the messages they need in order to function, they gradually weaken and deteriorate.
