Parkinsonism after glycine‐derivate exposure

Abstract

This 54‐year‐old man accidentally sprayed himself with the chemical agent glyphosate, a herbicide derived from the amino acid glycine. He developed disseminated skin lesions 6 hours after the accident. One month later, he developed a symmetrical parkinsonian syndrome. Two years after the initial exposure to glyphosate, magnetic resonance imaging revealed hyperintense signal in the globus pallidus and substantia nigra, bilaterally, on T2‐weighted images. Levodopa/benserazide 500/125 mg daily provided satisfactory clinical outcome.
