What Is It?
Guillain-Barré syndrome is an uncommon disorder that causes damage to the peripheral nerves. These nerves send messages from the brain to the muscles, instructing the muscles to move.

Guillain-Barré syndrome can become a medical emergency if the weakness affects the chest muscles responsible for breathing. If chest muscles become paralyzed, the patient can die from lack of oxygen.
