title: Cerebellar ataxia and acute motor axonal neuropathy associated with Anti GD1b and Anti GM1 antibodies.
abstract: The anti-GD1b antibody is known to bind to the cerebellar granular layer or spinocerebellar Ia fibers. A few cases of anti-GD1b positive acute inflammatory demyelinating polyneuropathy with prominent cerebellar ataxia were reported. Recently, we encountered a middle-aged woman with Guillain Barré syndrome (GBS) with severe cerebellar ataxia and relatively mild motor weakness. Anti-GD1b Ig G antibody and anti-GM1 Ig G antibody titers were markedly elevated in her serum. She was diagnosed with acute motor axonal neuropathy (AMAN) with prominent cerebellar ataxia based on the results of the serial nerve conduction study suggesting axonal neuropathy. This case presents the clinico-pathogenic role of autoantibodies to the GD1b and the GM1 in acute inflammatory neuropathy.
