E8.7

The Catatonic Patient

Often missed because it doesn't look like classic psychiatric illness. The lorazepam challenge confirms and treats.

Encounter card

Setting

Often inpatient (psychiatric or medical), sometimes ED — catatonic syndrome can arise from mood, psychotic, autoimmune, or medical causes.

Opening move

Recognize the syndrome. Bush-Francis Catatonia Rating Scale features. Lorazepam challenge. If responsive, scheduled lorazepam + treat underlying cause. If unresponsive, ECT is highly effective.

Sample language

"(may be unable to communicate verbally with the patient)"
"(to family) I think your son may have something called catatonia — let me explain."
"(during lorazepam trial) I'm giving him a medication called lorazepam. It often works dramatically."
"(when patient regains speech) Can you tell me what you remember? How are you feeling?"

Listen for

Bush-Francis features: stupor, mutism, posturing, waxy flexibility, negativism, echolalia, echopraxia, stereotypy, automatic obedience. Underlying cause clues — mood symptoms preceding, psychotic features, medical context.

Common pitfalls

Missing catatonia in patients labeled "uncooperative" or "depressed." Antipsychotic monotherapy in catatonia (can worsen). Failing to do the lorazepam challenge. Missing medical causes.

Red flags / escalate: Malignant catatonia (catatonia + autonomic instability + hyperthermia) — life-threatening, ECT often indicated. NMS in patient on antipsychotic.

Real-world reality: Catatonia is among the most missed psychiatric conditions — partly because the bedside test is brief but easy to skip when the patient is "just depressed." 30 minutes for lorazepam challenge can be transformative.

Catatonia is treatable and the response is often dramatic. The cost of missing it is high.

Catatonia is one of the more often missed conditions in psychiatry, and that miss has substantial consequences because catatonia is treatable — sometimes dramatically so. The patient who has been "uncooperative" or "severely depressed" for days may be catatonic and may respond to lorazepam challenge within 30 minutes.

The Bush-Francis features structure the diagnosis. Stupor (markedly reduced responsiveness despite intact consciousness). Mutism (decreased or absent speech). Posturing (maintaining unusual postures spontaneously). Waxy flexibility (the limb the examiner moves stays in the new position). Negativism (resistance to all instructions or opposition to all movement). Echolalia (repeating the examiner's words) or echopraxia (repeating their movements). Stereotypy. Automatic obedience. Mannerisms.

The lorazepam challenge is the bedside test that's both diagnostic and therapeutic. 1-2 mg IM or IV; response often within 30 minutes — the patient who couldn't speak begins speaking, the patient who was stuporous engages, the rigidity resolves. Positive response confirms catatonia and starts the treatment. If responsive, continue scheduled lorazepam every 6-8 hours, taper as the underlying cause is addressed.

Underlying causes include affective (depression, mania, bipolar disorder), psychotic (schizophrenia), autoimmune (anti-NMDA receptor encephalitis), medical (encephalitis, metabolic disorders), and substance-related. Workup should include EEG, brain imaging, autoimmune panel for new-onset cases, plus the usual medical screen for any acute change in mental status.

Avoid antipsychotic monotherapy in catatonia. Antipsychotics — especially D2 antagonists — can worsen catatonia and precipitate NMS, which shares features with severe catatonia. Treat the catatonia with benzodiazepines first; if the underlying condition is schizophrenia, add antipsychotic after the catatonia resolves.

If lorazepam-unresponsive, ECT is highly effective for catatonia and should be considered without delay. Particularly urgent in malignant catatonia (catatonia plus autonomic instability plus hyperthermia) — life-threatening, ICU-level care, ECT often first-line.

Family education matters. Catatonia is alarming for families; explaining what it is, what we're treating, and what the response should look like reduces the distress that the visible picture produces.

The anchor

Catatonia is treatable and often missed. Recognize Bush-Francis features. Lorazepam challenge confirms and treats. ECT for refractory or malignant catatonia.

Malignant catatonia — autonomic instability, hyperthermia, life-threatening. ECT often first-line. Margin clusters on the recognition.

Prove it

A 50-year-old man with no prior psychiatric history is admitted for "depression and not eating." He hasn't spoken for 3 days. On exam, he holds his arm up when you raise it (waxy flexibility) and resists movement (negativism). Diagnosis and management?
