Delirium is a transient global disorder of cognition and is very common in hospitalized patients. Nearly 30% of older patients (age >65 years) experience delirium at some time during hospitalization, and 40% of older patients admitted to intensive care units will have delirium.1 Risk factors for delirium include dementia, stroke, Parkinson disease, and sensory impairment. Polypharmacy (particularly the use of psychoactive drugs), infection, dehydration, the use of restraints, and catheters have been associated with the development of delirium.
