Alcohol addiction, also known as alcohol use disorder (AUD), is diagnosed when a person has a persistent and compulsive pattern of alcohol use that leads to significant impairment or distress, and meets certain diagnostic criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). These criteria include impaired control over alcohol use, continued use of alcohol despite negative consequences, and the development of tolerance and withdrawal symptoms. A diagnosis of alcohol addiction is made based on the severity of symptoms, ranging from mild to severe, and can be treated through a variety of interventions such as therapy, medications, and support groups.
