Abstract
|
|
|
|
A 57-year-old man developed motor weakness and paresthesia after acute enteritis. Nerve conduction study revealed decreased compound muscle action potentials in median nerves and conduction blocks in ulnar nerves. Serum IgG anti-GM1 antibody was positive. Conduction blocks rapidly disappeared through sequential studies, which are defined as reversible conduction failure (RCF). This study represents anti-GM1 antibody-associated acute motor conduction block neuropathy based on RCF. We underline that serial nerve conduction studies might be required for characterization of clinical and electrophysiological features.
