Catatonia: Assessment and Treatment

Assessment of catatonia combines observation, physical examination and a history of the changes in movement, speech and responsiveness. Clinicians may use a structured rating scale to document signs and follow response. They investigate possible causes, including mood or psychotic disorders, medication effects, seizures and other neurological or medical illnesses. Tests are selected according to the presentation rather than one universal panel.

Catatonia is a syndrome involving marked changes in movement, speech and responsiveness. It can occur with mood disorders, psychotic disorders and medical or neurological illnesses. It is not simply a severe negative symptom, and the presence of catatonic signs requires careful clinical assessment.

Immediate care addresses hydration, nutrition, immobility and other complications. A supervised benzodiazepine challenge may support assessment and treatment, but response is not a substitute for the wider clinical picture. Benzodiazepines and electroconvulsive therapy are important treatment options; selection depends on severity, response and medical circumstances. Medication review is essential because some drugs may contribute to the syndrome or complicate management. Treatment should not be attempted through unsupervised dose changes. Prompt recognition is especially important when fever, autonomic instability or marked physical deterioration suggests a potentially life-threatening presentation requiring urgent specialist and medical care.

Assessment also considers conditions that resemble or overlap with catatonia, including delirium, seizures and severe medication reactions. Distinguishing them may require specialist examination and targeted tests. A structured rating can track signs, but the urgency of care is determined by the whole presentation, particularly hydration, nutrition, temperature, vital signs and the risk of physical complications.
