Answer

A pure sensory variant of GBS has been described in the literature. It is typified by a rapid onset of sensory loss, sensory ataxia, and areflexia in a symmetrical and widespread pattern. Lumbar puncture studies show albuminocytologic dissociation in the CSF, and results from electromyography (EMG) show characteristic signs of a demyelinating process in the peripheral nerves.

The prognosis in pure GBS is generally good. Immunotherapies, such as plasma exchange and the administration of IVIGs, can be tried in patients with severe disease or slow recovery.
