Guillain Barré Syndrome, Chronic Inflammatory Demyelinating Polyradiculoneuropathy
Our Study Aims to Determine if Nerve Alterations in Acute GBS and CIDP Detectable by Ultrasound Match Electrodiagnostic Findings and if This Method Aids Early Diagnosis, Predict Their Outcomes and Differentiate Between Axonal and Demyelinating Subtypes.
Neuromuscular ultrasound (NMUS) is emerging as a valuable non-invasive diagnostic tool. In GBS, NMUS can detect proximal nerve enlargement early, before neurophysiological changes.
