What do you need to know about Guillain Barre syndrome?

Guillain-Barré syndrome (GBS) is a rare neurological disorder in which the body’s immune system mistakenly attacks part of its peripheral nervous system—the network of nerves located outside of the brain and spinal cord. GBS can range from a very mild case with brief weakness to nearly devastating paralysis,…

How does molecular mimicry work in Guillain Barre syndrome?

Different mechanisms may explain how the molecular mimicry concept may work. When Guillain-Barré syndrome is preceded by a viral or bacterial infection, it is possible that the infecting agent has changed the chemical structure of some nerves. The immune system treats these nerves as foreign bodies and mistakenly attacks them.

How long does it take for Guillain Barre syndrome to stop progressing?

In total, about a third of people with Guillain–Barré syndrome continue to be able to walk. Once the weakness has stopped progressing, it persists at a stable level (“plateau phase”) before improvement occurs. The plateau phase can take between two days and six months, but the most common duration is a week.
