What Causes Delirium?

What causes Delirium?


Delirium is usually caused by a medical illness or over exposure to medications, non-prescribed drugs, or alcohol. 

Infections are a common cause of delirium, especially urinary tract infections and pneumonia.

Delirium can be triggered by medications prescribed for pain, sleep, and bladder problems.  If you feel confused when taking these, talk to your doctor or pharmacist.  Taking a lot of pills also increases the risk of delirium.

Sleep deprivation (such as in a hospital setting) can cause or worsen delirium.
