Hyperreflexia in a patient with motor axonal Guillain-Barré syndrome.
We report a patient who presented after an episode of diarrhoea with ascending, symmetrical weakness without sensory loss, and without sphincter or other autonomic dysfunction. On clinical examination there were no cranial nerve deficits. Hyperreflexia of tendon jerks without other upper motor neurone signs was found. Electrophysiological examination demonstrated acute distal symmetrical motor axonal polyneuropathy. No electrophysiological signs of peripheral nerve demyelination or central nervous system involvement were found. Albuminocytologic dissociation was present in the cerebrospinal fluid. Stool culture and serological tests were inconclusive. Our patient's clinical picture was, apart from hyperreflexia of tendon jerks throughout the disease, characteristic of Guillain-Barré syndrome. This is the first such patient reported in Europe. The aetiology remained unclear. We suggest that selective axonal motor fibre affection, with possible mild pyramidal involvement, caused tendon jerk hyperreflexia.
