What is Delirium

Delirium is a short-term mental state characterized by disturbed attention, awareness and cognition. It may be triggered by an organic disturbance such as a tumor or a reversible cause such as drug withdrawal or substance intoxication.

Causes and signs of delirium

Medical professionals have several tools to diagnose delirium, including physical exams, a cognitive health assessment and laboratory tests. These tests help medical professionals distinguish delirium from other mental disorders and determine the underlying cause.





The onset of delirium is rapid, often over hours or days and the symptoms fluctuate in severity. People can become confused, agitated or resist care. They might have hallucinations and see things that aren't there.

Indicators of delirium include sudden changes in a person's mental status, including difficulty paying attention or thinking about what other people are saying to them. These changes can be difficult to detect, because a person with delirium often doesn't know they're having trouble thinking.

Symptoms of delirium typically come and go over the course of the day and are often worse at night. They're usually better in a few days or weeks but can last longer.

If you think your loved one is having problems, talk to their doctor or nurse right away. They will help them figure out what's going on and give you advice about how to take care of them.
