Abstract
We report on a case of anti-N-Methyl-D-Aspartate receptor antibody encephalitis, and review cases and series previously published in the literature. Anti-N-Methyl-D-Aspartate receptor antibody encephalitis usually occurs in young female patients with no past medical history, in whom an ovarian teratoma is often detected. They subacutely develop predominantly psychiatric symptoms, followed by severe neurological disorders requiring transfer to the intensive care unit and prolonged ventilatory support. Complete or substantial recovery depends on early diagnosis, removal of the teratoma and immunotherapy. Our purpose is to focus intensivists’ attention on this potentially lethal disorder, which should always be considered in young women admitted to the intensive care unit with characteristic neuropsychiatric disorders.
