Delirium tremens is a severe form of alcohol withdrawal. It involves sudden and severe mental or nervous system changes.
Delirium tremens can occur when you stop drinking alcohol after a period of heavy drinking, especially if you do not eat enough food.
Delirium tremens may also be caused by head injury, infection, or illness in people with a history of heavy alcohol use.
