Summary

Neuromuscular ultrasound (NMUS) is emerging as a valuable non-invasive diagnostic tool. In GBS, NMUS can detect proximal nerve enlargement early, before neurophysiological changes. Persistent nerve enlargement can be observed up to 15 years, though its correlation with disability varies. Research is needed to clarify NMUS findings in GBS and CIDP over time. Early detection of nerve root enlargement via NMUS could facilitate earlier diagnosis and intervention, improving patient outcomes and understanding of these conditions\' pathophysiology. This 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. The investigators will perform serial nerve ultrasounds and NCS to investigate nerve morphology, predict outcomes, and differentiate between axonal and demyelinating subtypes.
