Abstract:
Anti-N-methyl-ᴅ-aspartate receptor (NMDAR) encephalitis is a rare disease with a range of neurological and psychiatric presentations. Antibodies against NMDAR receptor are purported to be pathologic, and the two known potential immunological triggers are tumors and viral infection. In half of the cases, the trigger is not known. We present two cases where stress seemed to have triggered encephalitis. These cases illustrate the possible role of stress in leading to immune dysregulation, which can lead to encephalitis. We review the role of stress in anti-NMDAR encephalitis and possible mechanisms by which stress can trigger an immune dysregulation.
