Alcohol use disorder, or AUD, is the medical diagnosis for drinking that has turned harmful and hard to control. Doctors apply the DSM-5 criteria and grade it by symptom count: 2 to 3 is mild, 4 to 5 is moderate, and 6 or more is severe. It is the modern term for what many people still call alcoholism. Screening tools like the AUDIT and CAGE questionnaire help providers catch it early.
The Signs And Symptoms Of AUD
The core signs are loss of control over the amount, strong cravings, needing more alcohol for the same effect, withdrawal when the drinking stops, and continuing anyway despite the damage. Responsibilities slip. Hobbies and friendships get dropped. Many people pass through a long stretch of alcohol abuse before meeting the full criteria. Genetics account for roughly 60% of the risk. Stress, trauma, peer pressure, and untreated depression or anxiety supply the rest.
How Withdrawal And Tolerance Work
Tolerance builds as the brain adapts to regular alcohol, so it takes more to reach the same place. Withdrawal is the reverse. The brain must relearn how to function without a substance it now expects, and symptoms range from anxiety and tremors to seizures and delirium tremens. This is the part families most need to hear. Someone who drinks heavily every day should never stop abruptly on their own. Severe withdrawal can be life threatening and needs medical supervision, usually with benzodiazepines.
Treatment Options That Work Best For AUD
Care usually begins with medical detox, typically 3 to 7 days. Medication comes next. Naltrexone blunts the reward alcohol produces, acamprosate steadies brain chemistry, and disulfiram makes drinking physically unpleasant. They work best alongside behavioral therapy: CBT to spot triggers and plan for risky moments, or motivational interviewing for mixed feelings about quitting. Because AUD so often travels with depression, anxiety, or PTSD, both have to be treated together. Peer support such as AA or SMART Recovery, plus family who hold steady boundaries, carries recovery forward.
