Increased cerebrospinal fluid protein and motor conduction studies as prognostic markers of outcome and nerve ultrasound changes in Guillain-Barré syndrome

Axonal affection in motor studies, but not increased CSF protein at disease onset, seems to be an infavourable prognostic factor for outcome in GBS. Both axonal affection and increased CSF protein have a minor prognostic role in the development of nerve ultrasound changes.
