Catatonia is a syndrome that is most relevant to schizophrenia because it involves extreme motor behavior and requires urgent assessment. Which description best captures catatonia?

• A. Catatonia is marked motor immobility or marked agitation with abnormal movements or behavior; urgent assessment and may indicate psychiatric or medical complications.
• B. Catatonia is a mood swing episode.
• C. Catatonia is a type of seizure disorder.
• D. Catatonia is a memory deficit.

Answer: (A)

Catatonia is a psychomotor syndrome most often associated with schizophrenia-spectrum disorders. It presents with either extreme motor immobility (stupor) or marked motor agitation, often accompanied by abnormal movements or behaviors such as posturing, waxy flexibility, mutism, negativism, echolalia, or echopraxia. Because catatonia can signal medical complications or progress to malignant catatonia with fever and autonomic instability, urgent assessment is essential to identify underlying psychiatric or medical causes and to start prompt treatment. Treatments like benzodiazepines or electroconvulsive therapy can be effective, but timely evaluation is critical to prevent serious outcomes. The description that matches this best emphasizes the motor spectrum and the need for urgent assessment due to potential complications. The other options describe mood episodes, seizure disorders, or memory deficits, which do not capture the characteristic psychomotor features of catatonia.
