Synopsis
Etiologies of delirium are broad and include systemic toxic, metabolic, nutritional, infectious, or pharmacologic causes as well as acute brain disorders (eg, stroke, seizures). Delirium is classically thought to be transient, although not all patients return to their baseline. Delirium can be hyperactive, with psychomotor agitation and emotional disturbances, or hypoactive.
See Drug Reaction Data table for a list of potential pharmacologic causes. Related topic: Drug-induced psychosis.
