Expert Opinion :
Usually, Guillain Barre Syndrome (GBS) is characterized by areflexia, ascending paralysis, and demyelination of the peripheral nerve. However, variants of GBS may present with only areflexia or areflexia and ataxia and even ophthalmoplegia (Miller Fisher Variant) without limb weakness. In a child with GBS, it would be expected that with the recovery of disease and return of power, the reflexes should also improve. However, if there is some amount of sensory deficit (which is not uncommon in GBS), though the power may improve, reflexes may still not come back. These sensory deficits may be subtle and not picked up on nerve conduction studies. A nerve biopsy may show demyelination in such a case. However, recovery usually occurs over a period of time.
