Full Definition
Catatonia is a complex neuropsychiatric syndrome characterized by psychomotor immobility and behavioral abnormalities that can occur in various psychiatric and medical conditions. The syndrome includes symptoms such as stupor, catalepsy, waxy flexibility, mutism, negativism, posturing, mannerisms, stereotypies, agitation, grimacing, echolalia, and echopraxia. Catatonia can present as excited (hyperkinetic) or withdrawn (hypokinetic) forms and may occur in mood disorders, schizophrenia, medical conditions, or as a medication side effect. The condition represents a medical emergency when severe, as it can lead to complications such as dehydration, malnutrition, pulmonary embolism, or neuroleptic malignant syndrome. Diagnosis requires specific criteria and prompt treatment, typically with benzodiazepines or electroconvulsive therapy.
