Patients with Herpes Simplex virus Encephalitis are seen to have a relapse of symptoms namely seizures and choreoathetoid movements along with impairment of consciousness1. Though infective relapse is a possibility requiring extended antiviral therapy2, immune mediated mechanism is most probable.3 Although there is a similarity of symptoms between relapsing HSVE and N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis, the most likely culprit is the latter.
