Remember back in MF1... Ron Chen is a 25 year old computer sciences graduate student who had been previously well. Three weeks ago he suffered a viral gastroenteritis from which he has recovered. Over the past week, he has noticed increasing weakness of his limbs, starting with his legs, and progressing to involve his arms. He reports he has experienced patchy areas of sensory loss, symmetrically (glove and stocking distribution). He has also noticed occasional clumsy speech and facial weakness. He is admitted to the hospital (medical ward) with a diagnosis of Guillain Barré syndrome. You see him in followup 12 months later. After spending 3 weeks in hospital, 4 weeks in a rehabilitation center and then having physiotherapy for the rest of the year, Ron is almost completely back to normal. He still reports some weakness with extension of his toes on the right, but this does not impair his functioning. During his visit, he asks if he will ever get the strength back in his toes, and whether this could happen again
