Pulmonary embolism as a complication of major depressive disorder with catatonic features: a case report.

Catatonia in the setting of a mood disorder, an organic process, or a psychotic disorder presents significant risk to the patient's well-being, as well as an additional barrier to treating the underlying disorder. The signs and symptoms of catatonia interfere severely with essential activities of daily living; they also at times compromise the ability of caregivers to evaluate and treat the patient's primary disorder driving the catatonia. This interference often leads to medical emergencies, such as marked dehydration and pressure ulcers.
