Morvan’s syndrome associated with voltage-gated K channel antibodies

Abstract

A 62-year-old man presented with a 6-week history of insomnia, malaise, anorexia, hyperhidrosis, and burning pain in both feet. He developed an unsteady gait, drowsiness, fluctuating confusion, generalized headache, and vomiting 3 days before presentation. Five months earlier he was treated for legionella pneumonia. He had presented 15 years earlier with an acute confusional state and vomiting. The cause of these earlier symptoms was not found, but he recovered fully.
