Alcohol Use Disorder (AUD) is diagnosed using 11 DSM-5 criteria — any 2 or more in a 12-month period qualifies. Severity ranges from mild (2–3 criteria) to moderate (4–5) to severe (6+). The most reliable behavioral signs: drinking more than you planned, inability to cut back despite trying, craving between drinks, and continued drinking despite consequences. Physical dependence — tolerance and withdrawal — is present in more severe cases. Alcohol withdrawal is medically dangerous and should not be attempted without medical supervision if drinking is heavy.
Alcohol Use Disorder affects roughly 1 in 8 adults in the United States — about 29 million people. Yet most people with AUD don't recognize it as a clinical condition because the diagnostic threshold is lower than most people expect, and because alcohol's social normalization makes it easier to rationalize continued use.
The DSM-5 (2013) unified the older categories of "alcohol abuse" and "alcohol dependence" into a single spectrum diagnosis. This shift matters: you don't need physical withdrawal symptoms to meet the criteria. Loss of control over drinking is sufficient.
Loss of control (quantity): Drinking more, or for longer, than intended
Unsuccessful control: Persistent desire or repeated unsuccessful efforts to cut down or control drinking
Time spent: A great deal of time spent obtaining alcohol, using it, or recovering from its effects
Craving: A strong desire or urge to use alcohol
Failure to fulfill obligations: Recurrent alcohol use resulting in failure to fulfill major role obligations at work, school, or home
Social/interpersonal problems: Continued drinking despite persistent social or interpersonal problems caused or worsened by it
Giving up activities: Important social, occupational, or recreational activities given up or reduced because of alcohol
Hazardous use: Recurrent drinking in situations where it is physically hazardous (driving, operating machinery)
Continued despite harm: Drinking despite knowing it is causing or worsening a physical or psychological problem
Tolerance: Needing significantly more alcohol to achieve the same effect, or diminished effect with the same amount
Withdrawal: Characteristic alcohol withdrawal symptoms, or drinking to avoid them

criteria met
Planning to have two drinks and consistently having six. The gap between intention and behavior is the core behavioral marker.
Trying to stop or cut back and returning to the same or greater use despite genuine desire to change.
Drinking secretly, understating intake to doctors or partners, or buying alcohol from different stores to avoid judgment.
Planning your schedule, social activities, or travel around guaranteed access to alcohol.
Shaking hands in the morning that resolves after the first drink — a hallmark of physical dependence and withdrawal onset.
Excessive sweating, particularly at night or in the morning, unrelated to heat or exertion — an autonomic withdrawal response.
Needing 2–3× more alcohol to feel the same effect that one or two drinks used to produce — a sign of neuroadaptation.
Alcohol disrupts REM sleep. Drinkers often wake at 3–4am as blood alcohol drops — perpetuating the use cycle.
Reaching for alcohol to manage anxiety, depression, anger, loneliness, or boredom — rather than for enjoyment.
Thinking about alcohol between drinking sessions — when you'll next drink, whether there's enough at home, how to get more.
Anxiety, irritability, or restlessness when you haven't drunk that resolves quickly with a drink — classic withdrawal-driven craving.
Minimizing the problem, comparing yourself to "real" alcoholics, or rationalizing why your use is different or controlled.
⚠️ Critical safety information: Alcohol withdrawal is one of the only withdrawal syndromes that can be life-threatening. Unlike opioid, cannabis, or nicotine withdrawal, alcohol withdrawal can cause seizures and delirium tremens (DTs). Anyone who drinks heavily daily should not stop cold turkey without medical supervision.
6–12 hours: Anxiety, tremor, sweating, headache, nausea, insomnia. CIWA-Ar score typically 8–15.
12–24 hours: Risk of alcoholic hallucinosis (auditory, visual, or tactile hallucinations with intact orientation). Blood pressure and heart rate elevated.
24–48 hours: Peak seizure risk. Tonic-clonic seizures occur in approximately 5–15% of people withdrawing without medical management.
48–72 hours: Risk of delirium tremens — confusion, severe autonomic instability, high fever. DTs carry a 5–15% mortality rate without treatment, reduced to under 1% with proper medical care.
Medical detox is available and effective. Benzodiazepines (primarily diazepam or lorazepam) are the standard of care and make withdrawal safe. SAMHSA helpline: 1-800-662-4357.
Alcohol acts on multiple neurotransmitter systems simultaneously — GABA (inhibitory), glutamate (excitatory), dopamine (reward), and opioid receptors (pleasure). This broad pharmacological action produces stronger reinforcement than most substances and creates significant neuroadaptation with chronic use.
With chronic heavy drinking, the brain compensates by upregulating excitatory (glutamate) systems and downregulating inhibitory (GABA) systems. When alcohol is removed, this compensatory state is unmasked — producing the hyperexcitable state of withdrawal, including the seizure risk.
The reward system changes are equally significant. Alcohol elevates dopamine in the nucleus accumbens by 40–360% above baseline (Di Chiara & Imperato, 1988). Over time, the baseline dopamine system becomes blunted — producing anhedonia (inability to feel pleasure) without alcohol, which perpetuates use as self-medication.

For anyone with heavy daily drinking — medically supervised detox prevents dangerous withdrawal. Ask your doctor or call SAMHSA for referrals to inpatient or outpatient detox facilities.
Naltrexone (Vivitrol), acamprosate (Campral), and disulfiram (Antabuse) are FDA-approved and significantly improve outcomes — most effectively combined with behavioral therapy.

The DSM-5 defines 11 criteria for Alcohol Use Disorder — any 2 in a 12-month period qualifies. Key symptoms: drinking more than intended, failed attempts to cut back, craving, continued use despite consequences, tolerance, and withdrawal. Severity depends on how many criteria are met: 2–3 = mild, 4–5 = moderate, 6+ = severe.
Yes — alcohol withdrawal is one of the few that can be life-threatening. Seizures occur in 5–15% of heavy drinkers who stop abruptly. Delirium tremens (DTs) carries significant mortality without treatment. Anyone who drinks heavily daily should not quit cold turkey without medical supervision.
Yes. Daily drinking isn't required for AUD. Loss of control over drinking, compulsive use, and craving define addiction — not the daily drinking pattern. Binge drinkers who go days without alcohol can still meet the diagnostic criteria.
The DSM-5 eliminated these two categories and replaced them with a single spectrum: Alcohol Use Disorder (mild, moderate, severe). This better reflects the reality that alcohol problems exist on a continuum and that physical dependence (tolerance and withdrawal) isn't required for a diagnosis.
Three FDA-approved medications: naltrexone (reduces craving and the reward from drinking), acamprosate (reduces post-acute withdrawal discomfort), and disulfiram (creates aversive reaction to alcohol). All are most effective combined with behavioral therapy. Talk to your doctor or an addiction medicine specialist.
Avoid enabling (covering consequences), express concern without ultimatums in a calm moment, learn about AUD as a medical condition, offer specific help (accompanying them to a doctor appointment, not lecturing), and consider Al-Anon for your own support. SAMHSA (1-800-662-4357) provides guidance for families.
