The typical patient with GBS presents 2-4 weeks following a relatively benign respiratory or gastrointestinal illness, with complaints of finger dysesthesias and proximal muscle weakness of the lower extremities. The mean time to the clinical function nadir is 12 days, with 98% of patients reaching a nadir by 4 weeks. A plateau phase of persistent, unchanging symptoms then ensues, followed days later by gradual symptom improvement. Bowel and bladder dysfunction are rarely early or persistent findings. Papilledema secondary to elevated intracranial pressure is present in rare cases. Tonic pupils have been reported but only in severe cases.
