Voltage-Gated Potassium Channel Autoimmunity Mimicking Creutzfeldt-Jakob Disease

Abstract

Clinical, radiologic, electrophysiologic, and laboratory findings in VGKC autoantibody-associated encephalopathy may be confused with those of CJD. Serologic evaluation for markers of neurologic autoimmunity, including VGKC autoantibodies, may be warranted in suspected CJD cases.
