  • Title: Reversible conduction failure in pharyngeal-cervical-brachial variant of Guillain-Barré syndrome.
    Author: Capasso M, Notturno F, Manzoli C, Yuki N, Uncini A.
    Journal: Muscle Nerve; 2010 Oct; 42(4):608-12. PubMed ID: 20878742.
    Abstract:
    In two patients with the pharyngeal-cervical-brachial variant (PCB) of Guillain-Barré syndrome (GBS), low amplitude distal compound muscle action potentials and partial motor conduction blocks normalized without development of excessive temporal dispersion within 4 weeks. Sensory nerve action potentials significantly improved in amplitude or, when absent, rapidly became recordable at follow-up. Besides axonal degeneration, PCB is characterized by reversible conduction failure in both motor and sensory fibers and is in the continuous spectrum of axonal GBS subtypes.
