Guillain-Barre Syndrome in Children and Adolescents.

Guillain-Barre syndrome (GBS) is an immune-mediated disease of the peripheral nerves and cause of acute flaccid paralysis in children around the world. The most common type of GBS in North America targets myelin and leads to demyelinating neuropathy. Often there is a history of infection in the weeks preceding motor symptoms. GBS has been associated with different infections, including COVID. Children usually recover motor function, but autonomic instability and respiratory compromise can occur necessitating close observation and potentially intensive care unit admission.
