Guillain-Barre syndrome

Guillain-Barre syndrome is an autoimmune disorder encompassing a heterogeneous group of pathological and clinical entities. Antecedent infections are thought to trigger an immune response, which subsequently cross reacts with nerves leading to demyelination or axonal degeneration. Both intravenous immunoglobulin treatment and plasma exchange have been found to be equally beneficial. Several factors are useful in predicting the outcome of these patients.
