Anti–N-methyl-D-aspartate (anti-NMDA) receptor encephalitis is a treatable paraneoplastic disorder predominantly affecting young women. It is characterized by a combination of psychotic encephalopathy, seizures, and abnormal movements of the trunk and face, particularly in the form of jaw dystonia. Enhanced awareness of the typical presentation can increase the index of suspicion and facilitate initiation of appropriate treatment.
