Delirium, a term used to describe an acute confusional state, remains a major cause of morbidity and mortality, costing over $150 billion yearly in health care costs in the United States alone. Despite increased efforts targeting awareness of this condition, delirium often goes unrecognized in the face of evidence that it is usually the cognitive manifestation of serious underlying medical or neurologic illness.
