Pharmacologic Treatment of Malignant Catatonia Without Electroconvulsive Therapy: A Case Report

Malignant catatonia is a rare, life-threatening variant of catatonia requiring prompt treatment. Malignant catatonia is characterized by typical catatonia symptoms of psychomotor, neurologic, and behavioral changes complicated by autonomic instability, with an estimated mortality rate of 50% or more when untreated. Electroconvulsive therapy (ECT) is considered the definitive and most effective treatment for malignant catatonia, with minimal literature on the efficacy of pharmacological interventions alone. Timely access to life-saving ECT may be limited in some hospitals due to restrictive laws on the use of ECT when the patient is incapacitated or due to lack of treatment availability.

The patient was initially commenced on lorazepam but continued to deteriorate, subsequently developing complications of aspiration pneumonia and
