ICD-11 Criteria for Catatonia (BlockL1‑6A4)
Catatonia is a syndrome of
primarily psychomotor disturbances, characterized by the co-occurrence of
several symptoms of decreased, increased, or abnormal psychomotor activity. The
assessment of catatonia is complex and requires observation, interview and
physical exam. Catatonia can occur in the context of another mental disorder,
such as Schizophrenia or Other Primary Psychotic Disorders, Mood Disorders, and
Neurodevelopmental Disorders, especially Autism Spectrum Disorder. Catatonia
can also develop during or soon after intoxication or withdrawal from certain
psychoactive substances, including phencyclidine (PCP), cannabis, hallucinogens
such as mescaline or LSD, cocaine and MDMA or related drugs, or during the use
of certain psychoactive and non-psychoactive medications (e.g. antipsychotic
medications, benzodiazepines, steroids, disulfiram, ciprofloxacin). Finally,
Catatonia can occur as a direct pathophysiological consequence of a medical
condition not classified under Mental, Behavioural or Neurodevelopmental
Disorders. Examples of medical conditions that may be associated with Catatonia
include diabetic ketoacidosis, hypercalcemia, hepatic encephalopathy,
homocystinuria, neoplasms head trauma, cerebrovascular disease, and
encephalitis.
Exclusions:
- Harmful effects of drugs, medicaments or biological substances, not elsewhere classified (NE60)
