Chlorpyrifos-induced Delayed Myelopathy and Pure Motor Neuropathy

Abstract

Chronic neurotoxicity due to OP poisoning is dependent on several factors: chemical composition of the OP, dose systematized, and the administration of anitcholinergics for cholinergic crisis. The pathology of OP-induced delayed neuropathy involves a central-peripheral distal axonopathy. Peripheral distal axonopathy results in a predominantly motor polyneuropathy. Axonopathy of the central nervous system results in myelopathic features that makes for a poorer prognosis.
