Study Notes
Catatonia & Stupor Treatment
-
Treatments:
- Benzodiazepines: Often used for catatonic stupor; Lorazepam commonly used, up to 4mg daily; Might require higher doses (8-24mg), especially for stupor within affective/conversion disorder
- Electroconvulsive Therapy (ECT): Most effective treatment, especially when benzodiazepines fail; May be less effective in schizophrenia compared to mood disorders
-
Antipsychotics: Use with caution in catatonic patients; May be avoided by some clinicians, but successful cases with aripiprazole, risperidone, olanzapine, ziprasidone, and clozapine have been reported
- Clozapine and olanzapine: Strongest evidence support for treating catatonia
- Combination Therapy: Combining benzodiazepines and antipsychotics may be effective when individual treatments fail
Types of Catatonia
- Retarded Catatonia: Characterized by decreased psychomotor behavior, rigidity, mutism, negativism, posturing, waxy flexibility, and catalepsy; Often associated with schizophrenia, depression, mania, alcohol/benzodiazepine withdrawal, and conversion disorder
- Excited Catatonia: Characterized by agitation, combativeness, impulsivity, and apparently purposeless overactivity
Important Considerations for Catatonia
- Stupor in the context of affective/conversion disorder: Start with Lorazepam (2mg, increasing up to 4mg daily); Use IM (Intramuscular) route if necessary; If no response after 1-2 days, consider higher Lorazepam doses (8-24mg) or ECT
- Stupor in the context of psychotic disorder: Lorazepam (2mg, increasing to 4mg) is a possible treatment; If NMS possible, rule it out; If no NMS and patient NOT taking antipsychotics, consider SGAs (Second Generation Antipsychotics) like clozapine or olanzapine; If no response after 1-2 days, follow benzodiazepine/ECT protocol
- NMS (Neuroleptic Malignant Syndrome): Avoid antipsychotics if stupor develops during treatment, especially with symptoms of NMS and autonomic instability; Re-establishment of antipsychotics could be considered if NMS is ruled out, with adjunctive benzodiazepines
- Differential Diagnosis: Essential as catatonia can mimic other conditions like EPS (Extrapyramidal Side Effects) and NMS
- Malignant Catatonia: Stupor with autonomic instability or hyperthermia; Distinguishing it from NMS can be challenging
-
Catatonia & Physical Health: Untreated stupor can lead to complications like dehydration, venous thrombosis, pulmonary embolism, pneumonia, and death
- Causative factors: System disorders (e.g., subarachnoid hemorrhages, basal ganglia disorders), neurodegenerative conditions (e.g., dementia, Prader-Willi syndrome), drug withdrawals (e.g., clozapine, zolpidem, benzodiazepines, oncology medications)
- Treatment & History: Account for patient's history, previous diagnoses, and response to antipsychotics when deciding on a treatment plan; Non-adherence to treatment can precipitate stupor; Recognize that physical conditions can mimic catatonia
Catatonia in Schizophrenia
- Benzodiazepine Efficacy: Often less effective than in other types of catatonia; Response rate of 40-50%; Double-blind studies show limited effect on chronic catatonic symptoms in some cases
- Cochrane Review: Limited data on benzodiazepine use for catatonic schizophrenia; One study showed no significant difference between lorazepam and oxazepam
- ECT: Treatment of choice in catatonic schizophrenia patients despite potential decreased effectiveness compared to patients with mood disorders; Liberal stimulus dosing may be needed in malignant catatonia
Additional Information
- Antipsychotics: Can induce catatonia; Risk of NMS is higher in catatonic schizophrenia
- No Action: Not an option when life is at risk; Consider ECT if necessary
- Antipsychotic Use After Catatonia Resolution: Only after benzodiazepines or ECT have failed and a clear psychotic illness is present
