Neuroleptic malignant syndrome and acute motor axonal neuropathy after Campylobacter jejuni infection

Abstract

We report the case of a patient with Parkinson's disease who developed rapidly progressive weakness of the four limbs due to an acute motor axonal neuropathy (AMAN). This occurred days after a neuroleptic malignant syndrome (NMS). Serologic evidence of a preceding Campylobacter jejuni infection was detected and treatment with intravenous immunoglobulins proved effective. This case suggests that the rarely described neuropathies occurring with NMS may have a postinfectious immune basis and respond to immunomodulatory therapy.
