Delirium

摘要

Delirium is a common cause of disturbed behaviour in medically ill people and is often undetected and poorly managed. It is a condition at the interface of medicine and psychiatry that is all too often owned by neither. Although various terms have been used to describe it―including acute confusional state, acute brain syndrome, and acute organic reaction―delirium is the term used in the current psychiatric diagnostic classifications and the one we will use here.
