Catatonia is a state of neurogenic motor immobility and behavioral abnormality manifested by stupor. It was first described in 1874 by Karl Ludwig Kahlbaum, in Die Katatonie oder das Spannungsirresein[1] (Catatonia or Tension Insanity).

In the current Diagnostic and Statistical Manual of Mental Disorders published by the American Psychiatric Association (DSM-5) catatonia 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 or overdose (or both). It may also be seen in many medical disorders including infections (such as encephalitis), autoimmune disorders, focal neurologic lesions (including strokes), metabolic disturbances, alcohol withdrawal[2] and abrupt or overly rapid benzodiazepine withdrawal.[3][4][5]

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; benzodiazepines are a first-line treatment strategy. Electro-convulsive therapy is also sometimes used. There is growing evidence for the effectiveness of NMDA antagonists for benzodiazepine resistant catatonia.[6] Antipsychotics are sometimes employed but require caution as they can worsen symptoms and have serious adverse effects.[7]

Clinical features[edit]

Patients with catatonia may experience an extreme loss of motor skill or even constant hyperactive motor activity. Catatonic patients will sometimes hold rigid poses for hours and will ignore any external stimuli. Patients with catatonic excitement can suffer from exhaustion if not treated. Patients may also show stereotyped, repetitive movements.

They may show specific types of movement such as waxy flexibility, in which they maintain positions after being placed in them through someone else in which they resist movement in proportion to the force applied by the examiner. They may repeat meaningless phrases or speak only to repeat what the examiner says.

While catatonia is only identified as a symptom of schizophrenia in present psychiatric classifications, it is increasingly recognized as a syndrome with many faces. It appears as the Kahlbaum syndrome (motionless catatonia), malignant catatonia (neuroleptic malignant syndrome, toxic serotonin syndrome), and excited forms (delirious mania, catatonic excitement, oneirophrenia).[7] It has also been recognized as grafted on to autism spectrum disorders.[8]

Diagnostic criteria[edit]

According to the DSM-V, "Catatonia Associated with Another Mental Disorder (Catatonia Specifier)" is diagnosed if the clinical picture is dominated by at least three of the following: [9]

Subtypes[edit]

Rating scale[edit]

Fink and Taylor developed a catatonia rating scale to identify the syndrome.[7] A diagnosis is verified by a benzodiazepine or barbiturate test. The diagnosis is validated by the quick response to either benzodiazepines or electroconvulsive therapy (ECT). While proven useful in the past, barbiturates are no longer commonly used in psychiatry; thus the option of either benzodiazepines or ECT.

Treatment[edit]

Initial treatment is aimed at providing symptomatic relief. Benzodiazepines are the first line of treatment, and high doses are often required. A test dose of 1–2 mg of intramuscular lorazepam will often result in marked improvement within half an hour. In France, zolpidem has also been used in diagnosis, and response may occur within the same time period. Ultimately the underlying cause needs to be treated.[7]

Electroconvulsive therapy (ECT) is an effective treatment for catatonia as well as for most of the underlying causes (e.g. psychosis, mania, depression). Antipsychotics should be used with care as they can worsen catatonia and are the cause of neuroleptic malignant syndrome, a dangerous condition that can mimic catatonia and requires immediate discontinuation of the antipsychotic.[7]

Excessive glutamate activity is believed to be involved in catatonia; when first-line treatment options fail, NMDA antagonists such as amantadine or memantine are used. Amantadine may have an increased incidence of tolerance with prolonged use and can cause psychosis, due to its additional effects on the dopamine system. Memantine has a more targeted pharmacological profile for the glutamate system, reduced incidence of psychosis and may therefore be preferred for individuals who cannot tolerate amantadine. Topiramate, is another treatment option for resistant catatonia; it produces its therapeutic effects by producing glutamate antagonism via modulation of AMPA receptors.[13]
