Delirium:  Delirium is sudden severe confusion and rapid changes in brain function that occur with physical or mental illness. Delirium is most often caused by physical or mental illness and is usually temporary and reversible.

Many disorders cause delirium including conditions that deprive the brain of oxygen or other substances. Causes include: alcohol or sedative drug withdrawal, drug abuse, infections such as pneumonia and urinary tract infection, poisons and surgery.

Delirium is a medical emergency that requires immediate treatment. Most of the time delirium is caused by a number of factors. Delirium must be brought under control to prevent further brain damage. If the problem is caused by substance intoxication or the side effect of a medication, the substance should be stopped or the medication reduced under close medical supervision.
