Anti-N-methyl-d-aspartate receptor encephalitis triggered by emotional stress.

A 22-year-old woman presented with disorganized behaviors, restlessness, and subacute decline in mental status in the setting of stress. Extensive workup for autoimmune diseases disclosed positive anti-N-methyl-d-aspartate (NMDA) receptor antibodies. We recommend that fertility preservation should be discussed and stress management should be considered in patients with a history of anti-NMDA autoimmune encephalitis because this can help in preventing relapse.
