Cognitive disorders are the second most common psychiatric disorders in oncology. Delirium contributes to increased morbidity and mortality, treatment costs, and stress in caregivers. Delirium is more prevalent among the elderly, in high acuity and critical care patients, and those with end stage disease. Dementia also predisposes to delirium. Complicating assessment and treatment are: imprecise nomenclature for cognitive deficits; sometimes subtle, inconsistent, and overlapping signs and symptoms; and multiple etiologies.
