Acute sensory neuropathy: 2 year follow-up of sensory conduction.

Following flu-like illness a 75 year old man developed pure sensory neuropathy that reached a peak at 3 weeks. Cerebrospinal fluid protein was elevated with no increase in cell count The sensory deficits started to improve 4 months later, and were completely resolved 12 months later. Compound sensory nerve action potential, which had been absent initially, became detectable 8 months after the onset The revived sensory potentials progressively increased their size during the 2 year period. A variant of acute inflammatory demyelinating polyneuropathy may be part of a syndrome of acute sensory neuropathy.
