Answer

Guillain-Barré syndrome (GBS) can be described as a collection of clinical syndromes that manifests as an acute inflammatory polyradiculoneuropathy with resultant weakness and diminished reflexes. With poliomyelitis under control in developed countries, GBS is now the most important cause of acute flaccid paralysis. (See Clinical Presentation.)

Although the classic description of GBS is that of a demyelinating neuropathy with ascending weakness, many clinical variants have been well documented in the medical literature, and variants involving the cranial nerves or pure motor involvement and axonal injury are not uncommon. (See Pathophysiology.)
