A Case Report of Anti-N-Methyl-D-Aspartate Receptor (NMDAR) Encephalitis.

Anti-N-methyl-D-aspartate (NMDA) receptor NMDAR) encephalitis is a relatively recent condition, classified as an immune-mediated disorder characterized by a complex neuropsychiatric syndrome and the presence of anti-GluN1 subunit antibodies against the NMDA receptor in cerebrospinal fluid (CSF). Although it is a rare disease, studies have identified it as one of the most common causes of autoimmune encephalitis. The pathophysiology of this condition is not yet fully understood, especially regarding its association with ovarian teratomas and other neoplasms.
