Epidemiology

• Approximately five percent of hospital patients being treated for alcohol withdrawal experience AWD.

• It has a greater propensity to develop in males than females

CAUSESAWD only affects people with a history of heavy alcohol use. Heavy drinkers may develop this condition if they:• suddenly stop drinking• reduce their alcohol use too quickly• don’t eat enough when reducing alcohol use• have a head injury• are sick or have an infection
