Summary

This study looks at whether ultrasound can detect nerve changes in people with Guillain-Barré syndrome (GBS) and chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) earlier than standard tests. Researchers will compare ultrasound images with nerve conduction studies in 90 adults. The goal is to see if ultrasound can help diagnose these conditions faster and track how nerves change over time.
