Psychotherapy: 86b - Delirium

Psychology8 CardsCreated about 2 months ago

This flashcard set details the diagnostic criteria for delirium, including its rapid onset, fluctuating course, and cognitive disturbances linked to a physiological cause. It also outlines how delirium disrupts sleep architecture—eliminating deep and REM sleep—and describes the long-term cognitive decline many patients experience, often comparable to mild TBI or early Alzheimer’s disease.
