Nodopathies in the Early Diagnosis of Axonal Forms of Guillain-Barré Syndrome.

Introduction: Guillain-Barré syndrome (GBS) has been classified into demyelinating and axonal subtypes or forms, such as acute motor axonal neuropathy (AMAN) and regional pharyngeal-cervical-brachial variant (PCBv).

Objective: To study the relationship between motor nerve conduction blocks (CBs) and prognosis in AMAN and PCBv.

Patients And Methods: We retrospectively analyzed six cases of AMAN and PCBv with serial nerve conduction studies (NCS) and electromyography (EMG).
