the nervous system that is outside the brain and spinal cord. Autoimmune means an illness that occurs when the body tissues are attacked by its own immune system. In this case they begin attacking nerve cells which communicate with muscles. They attack the myelin sheaths surrounding the axons of the nerve cells. In some cases they have been known to attack the axons themselves. The first known incident of Guillain-Barre syndrome was reported in 1859 by a Frenchman named Jean Baptiste Octave Landry
