Understanding Alcohol Use Disorder

Alcohol use disorder, often shortened to AUD, is a medical condition in which a person finds it difficult to control their drinking despite negative consequences for their health, relationships, or daily life. It is what many people call alcohol addiction or alcoholism. The National Institute on Alcohol Abuse and Alcoholism describes AUD as a medical condition, and understanding it that way is the first step toward effective help.

Framing AUD as a health condition, rather than a moral failing, matters because it changes what comes next. A medical condition can be assessed, diagnosed, and treated. This guide explains how AUD is defined, how clinicians describe its severity from mild to severe, and why the condition is treatable at every point on that spectrum.

What alcohol use disorder is

Alcohol use disorder is characterized by an impaired ability to stop or control alcohol use despite harmful consequences. It involves changes in the brain that affect motivation, self-control, and the way a person responds to stress and reward. These changes help explain why simply deciding to drink less is often not enough on its own.

AUD can develop in anyone, regardless of background, age, or circumstance. It ranges from mild patterns that a person may not yet recognize as a problem to severe dependence that requires medical support to address safely. Because it develops gradually, many people live with AUD for years before seeking help.

How the DSM-5 describes AUD

Clinicians diagnose alcohol use disorder using criteria from the DSM-5, the diagnostic manual widely used in the United States. The DSM-5 lists a set of symptoms that describe patterns such as loss of control, continued use despite problems, cravings, tolerance, and withdrawal. A clinician considers how many of these criteria a person meets over a 12-month period.

Importantly, this framework treats AUD as a spectrum rather than an all-or-nothing condition. A person does not need to meet every criterion to have a diagnosable disorder, and the diagnosis focuses on patterns and consequences rather than on the amount a person drinks alone. Only a qualified clinician can make a diagnosis.

• Loss of control, such as drinking more or longer than intended
• Unsuccessful efforts to cut down or stop
• Strong cravings or urges to drink
• Continued drinking despite problems it causes
• Tolerance, meaning needing more alcohol for the same effect
• Withdrawal symptoms when not drinking

Severity levels: mild, moderate, and severe

The DSM-5 sorts alcohol use disorder into three severity levels based on how many criteria a person meets. This is a general framework, and the specific number of criteria for each level is determined by a clinician during assessment. The point of these levels is practical: they help match a person to the right kind of care.

Alcohol use disorder is treatable

One of the most important things to know about AUD is that it responds to treatment. The Substance Abuse and Mental Health Services Administration emphasizes that alcohol use disorder is common and that recovery is possible at any severity level. Treatment is not one-size-fits-all; it is matched to where a person is on the spectrum.

For milder patterns, counseling and outpatient support may be enough. For more severe AUD, especially where physical dependence is present, treatment often begins with medically supervised detox to manage withdrawal safely, followed by therapy and continued care. Medication can also play a role for some people as part of a broader plan.

How Ascend supports recovery from AUD

At Ascend Recovery Center in Albuquerque, alcohol use disorder is treated as the medical condition it is, with an individualized plan built around a person's history, health, and goals. When physical dependence is present, medically supervised detox with 24/7 nursing and CIWA monitoring provides a safe foundation. From there, care continues through residential, day treatment, and outpatient levels.

For alcohol use disorder, the medical team may recommend medication such as naltrexone, including the long-acting injectable form known as Vivitrol, alongside therapy. Because every level of care is available in one place, a person can move through the continuum as they progress, without changing providers.
