Ataxic Variant of Guillain-Barre Syndrome Associated with Anti-GD1b Ig G Antibody

ABSTRACT

It is known that anti GD1b antibody bind to the cerebellar granular layer or spinocerebellar Ia fiber. We recently encountered a patient of Guillain Barr syndrome (GBS) showing marked cerebellar ataxia and relatively mild quadriparesis but completely intact extraocular eye movement. Markedly high IgG anti GD1b antibody titer was identified from the patient's serum. The nerve conduction study showed reduction of compound muscle action potential without evidence of perpheral nerve demyelination. We report an ataxic variat of GBS associated with anti GD1b IgG antibody.
