system attacks and destroys the sheath of myelin that insulates motor nerves, which carry commands from the brain to the muscles and organs. Degeneration of the myelin sheath interferes with the transmission of nerve impulses, ultimately stopping their transmission altogether. Voluntary functions, such as the movement of limbs, and involuntary functions, such as bladder control, are lost, leading to paralysis, and eventually, death. Scientists do not know what stimulates the immune system to attack myelin.
