Guillain-Barre syndrome is a disorder that makes the immune system attacks the nerves. This syndrome is relatively rare and only affects 1-2 people per 100,000, but can strike anyone regardless of age. The disease is often followed by a mild infection such as pneumonia or gastrointestinal.
Damage to the nerve will cause numbness, muscle weakness and paralysis. This syndrome most often affects the nerve coverings (myelin sheath) that is called demyelination that causes nerve signals to move so much slower. Whereas damage to other nerves can make the nerve stop working altogether.
