title: [Multifocal motor neuropathy after administration of gangliosides].
abstract: A case of a 38 years-old male with motor neuropathy with multifocal conduction blocks following the administration of ganglioside therapy is reported. There was generalized weakness without areflexia and normal parameters of the spinal fluid, including protein values. Electrophysiological data showed multiple conduction blocks with normal nerve conduction velocities. Antibodies against asialo-GM1 gangliosides were present in the cerebrospinal fluid. There could be a relationship between the ganglioside administration and the development of an immune-mediated neuropathy. Several cases of demyelinating polyradiculoneuritis after ganglioside treatment have been reported. If this association is confirmed, the apparent lack of toxicity of gangliosides should be reconsidered.
