Catatonia means a person is awake, but does not move, talk, or react to anything but pain. The person can stay stiff and still for hours. A person with catatonia may look to be in a stupor (being mentally numb and in a daze). The cause is in the nervous system; the brain and nerves. This problem was first written about in 1874 in Die Katatonie oder das Spannungsirresein.[1]

Causes[change | change source]

Catatonia can sometimes happen with mental disorders. It can be a symptom of schizophrenia, bipolar disorder, post-traumatic stress disorder, and depression. Catatonia may also happen when a person abuses illegal drugs or overdoses by taking too much of a drug.

Catatonia can also be caused by many different medical disorders. Some causes are infections, such as encephalitis; autoimmune diseases; damage to the brain from strokes; and metabolic problems.

A person can also get catatonia from benzodiazepine withdrawal syndrome, which happens if the person quickly stops taking benzodiazepine medications.[2][3][4] Catatonia can also be a bad reaction to illegal drugs.

Treatment[change | change source]

Doctors can treat catatonia. They usually start with medicines such as benzodiazepines. If those medicines do not work; doctors may use shock therapy. Antipsychotic medicines can also be used, but with safety in mind. Sometimes they can make catatonia worse or have bad side effects.[5] A group of anesthetic drugs called NMDA antagonists may be helpful when benzodiazepines don't work.[6]
