Malignant Catatonia Warrants Early Psychiatric-Critical Care Collaborative Management: Two Cases and Literature Review

Abstract EN

Malignant catatonia (MC) is a life-threatening manifestation which can occur in the setting of an underlying neuropsychiatric syndrome or general medical illness and shares clinical and pathophysiological features and medical comorbidities with the Neuroleptic Malignant Syndrome (NMS).

The subsequent diagnosis and definitive therapy of MC are typically delayed, which increases morbidity and mortality.

We present two cases of MC and review recent literature of MC and NMS, illustrating factors which delay diagnosis and management.

When clinical features suggest MC or NMS, we propose early critical care consultation and stabilization with collaborative psychiatric management.
