Conditions InDepth: Alcohol Use Disorder (AUD)

AUD is marked by alcohol-related issues that include misuse, abuse, and dependency. It includes:

  • Binge drinking—Drinking large amounts of alcohol in a short amount of time
  • Alcohol abuse—Drinking even though it affects relationships, jobs, or family life
  • Alcohol dependence—Loss of control over drinking that leads to cravings, a tolerance for alcohol, and withdrawal when drinking is stopped

Causes

The exact cause is not known. Genetics may play a role. It may also involve changes in brain chemistry that affect how alcohol is processed by a person's body.
