Catatonia is a synrome of psychic and motoric disturbances. In the current Diagnostic and Statistical Manual of Mental Disorders published by the American Psychiatric Association (DSM-IV) it is not recognized as a separate disorder, but is associated with psychiatric conditions such as schizophrenia (catatonic type), bipolar disorder, post-traumatic stress disorder, depression and other mental disorders, as well as drug abuse and/or overdose. It may also be seen in many medical disorders including infections (such as encephalitis), autoimmune disorders, focal neurologic lesions (including strokes), metabolic disturbances and abrupt or overly rapid withdrawal from benzodiazepines. It can be an adverse reaction to prescribed medication. It bears similarity to conditions such as encephalitis lethargica and neuroleptic malignant syndrome. There are a variety of treatments available, and depending on the case, one or more drugs may be used, including antipsychotics and benzodiazepines.
