Amyotrophic lateral sclerosis (ALS, sometimes called Lou Gehrig's disease, Maladie de Charcot or motor neurone disease) is a progressive, fatal neurodegenerative disease caused by the degeneration of motor neurons. ALS is marked by gradual degeneration of the nerve cells in the central nervous system that control voluntary muscle movement. The disorder causes muscle weakness and atrophy throughout the body. In ALS, both the upper motor neurons and the lower motor neurons degenerate or die, ceasing to send messages to muscles. Unable to function, the muscles gradually weaken, waste away (atrophy), and have fasciculations because of denervation. Eventually, the brain completely loses its ability to initiate and control voluntary movement. The disease does not necessarily debilitate the patient's mental functioning in the same manner as Alzheimer's disease or other neurological conditions. Instead, those suffering advanced stages of the disease may retain the same memories, personality, and intelligence they had before its onset. less
