Overview

Delirium may be caused by severe physical or mental illness, or any process which interferes with the normal metabolism or function of the brain such as fever, pain, poison (toxic drug reactions), brain injury, surgery, traumatic shock, severe lack of food or water or sleep, and even withdrawal symptoms of certain drug and alcohol dependent states. In addition, there is an interaction between acute and chronic symptoms of brain dysfunction. Delirious states are more easily produced in people already suffering from underlying chronic brain dysfunction. A very common cause of delirium in elderly people is a urinary tract infection, which is easily treatable with antibiotics. Delirium, like mental confusion, is a very general and nonspecific symptom of organ dysfunction. In addition to many organic causes relating to a structural defect or a metabolic problem in the brain, there are also some psychiatric causes, which may also include a component of mental or emotional stress, mental disease.
