A Subacute Behavioral Disorder In a Female Adolescent. Autoimmune Anti-N-methyl-D-aspartate Receptor Encephalitis Associated with Ovarian Teratoma

      A 17-year-old Belgian female patient, without a history of medical or psychiatric problems, had been living in Ireland since early September 2007. Around mid-November, her teacher noticed some excitability, agitation, euphoria, and even aggressiveness. She was eventually admitted to a local psychiatric hospital on November 24, 2007, for treatment of acute hypomania. There was no history of drug abuse. Brain computerized tomography was normal. She was treated with haloperidol and aripiprazole, 10 mg/day. She was then transferred to Belgium 3 days later.
