Anti-N-methyl-ᴅ-aspartate receptor encephalitis preceding stroke: report of an unusual case with literature review.

ABSTRACT: Anti-N-methyl-ᴅ-aspartate (anti-NMDA) receptor encephalitis is a well-known autoimmune encephalitis caused by antibodies against the GluN1 subunit of the anti-NMDA receptor (anti-NMDAR). Stroke, characterized by abrupt focal neurological deficits due to ischemic or hemorrhagic vascular insults, is rarely preceded by anti-NMDAR encephalitis. Here, we described a case of a 69-year-old female without any prior comorbidities who presented with acute stroke and left hemiparesis with a history of recent onset of neuropsychiatric symptoms. Her cerebrospinal fluid was positive for anti-NMDAR antibody, and significant improvement was noticed after the initiation of immunotherapy.
