can having gillian barre syndrom cause a mental disorder

Hello Anon

Thank you for writing.

For the benefit of our readers, Guillain-Barre is a rare autoimmune neurological syndrome in which your immune system attacks your peripheral nervous system. The syndrome usually starts within days or weeks of an infection, often a respiratory or gastrointestinal virus.

According to the American Association of Neuroscience Nurses (AANN), Guillain-Barre occurs in one to two people in every 100,000 annually, and is preceded by infection in 60-70 percent of cases. It can also appear after certain vaccines, or after surgery. It isn’t yet known why some people get it and others do not. Fortunately, the majority of people who experience Guillain-Barre fully recover. In about 30 percent of cases, there may be some residual weakness.

Anon, there does not appear to be a link between G-B and mental disorders, rather the combination may be coincidental.
Best,
Susan
