Electrophysiological studies in the Guillain-Barr� syndrome: Distinguishing subtypes by published criteria

Guillain–Barré syndrome (GBS) is recognized clinically by the presence of acute, rapidly progressive weakness, areflexia, and albuminocytological dissociation in cerebrospinal fluid. Although GBS was initially considered to be primarily an acute inflammatory demyelinating polyneuropathy (AIDP), several other subtypes have been recognized: acute motor axonal neuropathy (AMAN), acute motor-sensory axonal neuropathy (AMSAN), and Fisher syndrome...
