Amyotrophic lateral sclerosis. Amyotrophic lateral sclerosis, or ALS, is a disease of the nerve cells in the brain and spinal cord that control voluntary muscle movement. ALS is also known as Lou Gehrig's disease. 1 out of 10 cases of ALS are due to a genetic defect. The cause is unknown in most other cases. In ALS, motor nerve cells (neurons) waste away or die, and can no longer send messages to muscles. This eventually leads to muscle weakening, twitching, and an inability to move the arms, legs, and body.
