ALS, also known as Lou Gehrig's disease, is a neurodegenerative disease with no cure that destroys nerve cells. When the motor neurons are destroyed, the brain can no longer initiate and control muscle movement, which can lead to people losing the ability to speak, eat, move and breathe, the ALS Association detailed. The mean survival time for the disease is five years.
