Abstract
Long-term morbidity from Guillain–Barré syndrome (GBS) is caused by axonal damage. This prospective study demonstrated that neurofilaments (NfHs), a biomarker for axonal damage, were of prognostic value in GBS. CSF NfH levels correlated with the F score and Medical Research Council summed score and were higher in patients with neurophysiologic evidence of axonal degeneration compared to those without. Pathologically high CSF NfH levels (>0.73 ng/mL) predicted worse motor and functional outcome.
