title: Lorazepam treatment of psychogenic catatonia: an update.
abstract: Six papers have reported the efficacy of lorazepam in alleviating catatonic symptoms that have psychogenic causes. The authors report five new cases of catatonia; three patients responded favorably and two failed to respond to lorazepam. Investigation of the nonresponders revealed the presence of pernicious anemia in one and postpartum psychosis in the other. These findings demonstrate that lorazepam has an important role in the treatment of catatonic symptoms. Its effects appear to be specific for psychogenic catatonic states and for conditions in which biogenic amines, specifically dopamine and gamma-aminobutyric acid, play a part. The authors stress intramuscular administration of lorazepam for patients in catatonic states because this route provides the psychiatrist with immediate results that assist with early diagnosis and treatment.
