title: Treatment of catatonia with olanzapine and amantadine.
abstract: Catatonia is a disorder characterized by mutism, posturing, echophenomena, and negativism. The preferred treatment for non-malignant catatonia is benzodiazepines, which often produce a reduction in symptoms within 24 hours. Presented here is a case report of a 19-year-old woman appearing in a catatonic state that did not respond to lorazepam. On the basis of emerging evidence that atypical antipsychotics and weak N-Methyl-D-Aspartate (NMDA) receptor-antagonists may effectively treat catatonia, we treated our patient with olanzapine and amantadine, which resulted in a dramatic reduction in her catatonic symptoms.
