Causes, incidence, and risk factors:
Delirium tremens can occur after a period of heavy alcohol drinking, especially when the person does not eat enough food. It may also be triggered by head injury, infection, or illness in people with a history of heavy use of alcohol. It is most common in people who have a history of experiencing alcohol withdrawal when alcohol is stopped, especially in those who drink the equivalent of 7 - 8 pints of beer (or 1 pint of "hard" alcohol) per day for several months, and in those with a history of habitual alcohol use or alcoholism that has existed for more than 10 years.
Symptoms occur because of the toxic effects of alcohol on the brain and nervous system. They may be severe and progress rapidly.
