When the motor neurons die, the ability of the brain to initiate and control muscle movement is lost. As motor neurons degenerate, they can no longer send impulses to the muscle fibers that normally result in muscle movement. Death usually occurs within five years of the final diagnosis and is attributed to respiratory failure or cachexia. And they do not realize there is a link between chemical exposure and severe disease. Many of these illnesses are preventable.
Education is the key to prevention.
