olanzapine and Emergencies

Agitation can present as an emergency in the course of numerous psychiatric conditions including intoxication, schizophrenia, bipolar disorder, and delirium. This article reviews relevant literature regarding the definition, etiology, measurement, and management of episodic agitation and pays particular attention to intramuscular treatments. The impact of changes in methodology between the era of first- and second-generation antipsychotics, the implications of those changes for external validity of studies of second-generation studies, and the recent evolution of expert consensus are discussed.

A 19-year-old male came to the Emergency Room of our hospital due to an episode of dystonic movements and disorientation 4 days after consuming methamphetamine, which evolved to a catatonic frank syndrome and eventually to status epilepticus. Definitive diagnosis was anti-NMDA receptor encephalitis, an acute inflammation of the limbic area of autoimmune origin in which early diagnosis and treatment are key elements for the final outcome. In this case, initial normal tests and previous methamphetamine poisoning delayed diagnosis, because inhaled-methamphetamine poisoning causes similar clinical symptoms to anti-NMDA receptor encephalitis. Methamphetamine poisoning may have caused an immune response in the patient, bringing on the progress of the pathology.
