Catatonia Update.

Catatonia is a neuropsychiatric condition characterized by physical presentations ranging from profound immobility to excessive motor activity. Emotional aspects of catatonia vary clinically between psychomotor retardation and extreme excitability. In the past, catatonia was considered to be a variant of schizophrenia. However, the disorder actually occurs as a clinical expression of many different psychiatric, neurologic, or medical diagnoses. A prompt diagnostic evaluation should identify any underlying diseases with consideration of somatic pathologies, especially those affecting central nervous system function. The workup focuses on a range of metabolic, traumatic, infectious, degenerative, autoimmune, drug-related, or other possible conditions, including psychiatric etiologies. Appropriate interventions should be instituted as quickly as possible to avoid complications like dehydration or deep vein thromboses. Symptomatic treatment commonly includes various pharmaceuticals or electroconvulsive therapy. Benzodiazepine drugs are, and have long been, the most preferred pharmacotherapy. These medications are usually fast acting and effective, are safe, and remain the catatonia treatment of choice.
