Alcohol is the most widely used substance in the United States, and alcohol use disorder is the most common form of addiction. Yet it’s also one of the most misunderstood, in part because alcohol is legal, socially normalized, and rarely talked about with the same clinical seriousness as other substance use disorders.
That gap has consequences. People who need treatment often don’t recognize what they’re dealing with. Families don’t know what to look for. And because the line between social drinking and problematic drinking can feel blurry, many people spend years in denial about where they actually fall.
This article explains what alcohol use disorder is, how it’s diagnosed, what the warning signs look like across a spectrum of severity, and what getting help in Memphis actually involves.
What Alcohol Use Disorder Actually Is
Alcohol use disorder (AUD) is a medical diagnosis, not a moral judgment. It describes a pattern of alcohol use that involves loss of control over drinking, continued use despite negative consequences, and physical or psychological dependence on alcohol.
It is classified as a chronic brain disorder. Prolonged alcohol use changes how the brain regulates mood, manages stress, and responds to reward. Those changes don’t reverse the moment a person stops drinking, which is one reason why willpower alone is rarely sufficient for sustained recovery.
AUD exists on a spectrum. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5) classifies it as mild, moderate, or severe based on how many of eleven specific criteria a person meets within a twelve-month period. Someone who meets two or three criteria has mild AUD. Someone who meets six or more has severe AUD. Both are real diagnoses. Both warrant attention.
Signs and Symptoms Across the Spectrum
Because AUD exists on a spectrum, the signs don’t all look the same. Some are visible and disruptive. Others are easy to rationalize or minimize, especially by the person experiencing them.
The DSM-5 criteria include:
Drinking more, or for longer, than intended. Persistent desire or unsuccessful efforts to cut down. Spending significant time obtaining, using, or recovering from alcohol. Craving alcohol. Failing to meet obligations at work, school, or home because of drinking. Continuing to drink despite it causing social or relationship problems. Giving up activities that were once important because of drinking. Drinking in physically hazardous situations. Continuing to drink despite knowing it’s causing or worsening a physical or psychological problem. Needing more alcohol to achieve the same effect (tolerance). Experiencing withdrawal symptoms when not drinking.
Not every person with AUD will experience all of these. Someone with mild AUD might still hold a job, maintain relationships, and show few outward signs of a problem. That doesn’t mean the problem isn’t real or that it won’t progress.
The Difference Between Problem Drinking and Alcohol Use Disorder
These terms are sometimes used interchangeably, but they’re not identical.
Problem drinking refers to a pattern of alcohol use that causes harm, whether physically, socially, or professionally, without necessarily meeting the clinical threshold for AUD. Someone who regularly drinks to the point of poor decision-making, or whose drinking is causing friction in their relationships, may be a problem drinker without meeting enough DSM-5 criteria for a formal diagnosis.
The distinction matters because problem drinking is often a precursor to AUD. Patterns that feel manageable in their early stages tend to escalate. The absence of a formal diagnosis doesn’t mean intervention is premature. In fact, earlier intervention typically leads to better outcomes.
If there’s any uncertainty about where drinking falls on this spectrum, a formal addiction evaluation assessment is the most reliable way to find out. Serenity uses the Addiction Severity Index (ASI), a structured clinical interview that assesses alcohol and drug use alongside medical, psychological, family, and employment factors. It’s not a test to pass or fail. It’s a tool for getting an accurate picture of where someone is and what kind of support would actually help.
Why Alcohol Withdrawal Is Medically Serious
One aspect of AUD that’s frequently underestimated is the physical danger of stopping abruptly.
For people with moderate to severe AUD, alcohol withdrawal can be life-threatening. Unlike withdrawal from opioids, which is painful but rarely fatal, alcohol withdrawal can produce seizures, severe confusion, and a condition called delirium tremens (DTs) that carries real mortality risk if untreated. Symptoms can begin within hours of the last drink and peak between 24 and 72 hours.
This is why medically supervised detoxification is strongly recommended for people with significant alcohol dependence. Attempting to detox at home without medical oversight is dangerous. Serenity’s residential treatment program includes medically supervised withdrawal management as part of the intake process for clients who need it.
What Treatment for Alcohol Use Disorder Looks Like
There is no single treatment path for AUD. The appropriate level of care depends on the severity of the disorder, the presence of co-occurring mental health conditions, a person’s living situation, and other individual factors. Serenity determines the right fit for each person using ASAM criteria, the clinical framework developed by the American Society of Addiction Medicine.
For people with severe AUD or those who require medical supervision during withdrawal, residential treatment is often the starting point. Serenity’s residential program serves both men and women at its Midtown Memphis campus. Clients receive structured daily therapy, peer support, individual counseling, and grounding in Recovery Dynamics®, Serenity’s evidence-based clinical model built on a structured, step-by-step approach to the Twelve Steps.
For people with mild to moderate AUD who have a stable home environment, intensive outpatient treatment may be the right level of care. Serenity’s IOP programs, available at locations on Park Avenue and in Bellevue, provide 9 to 15 hours of structured therapy per week without requiring residential placement. This format allows people to continue working and maintain family responsibilities while receiving consistent clinical support.
Counseling is also available as a standalone service for people who need ongoing professional support but don’t require the intensity of residential or IOP care.
Alcohol Use Disorder in Memphis
Memphis has a documented and ongoing relationship with substance use that reflects broader national trends, compounded by factors common to many mid-sized Southern cities: economic pressure, limited access to mental health care, and a cultural reluctance to seek help for addiction.
Tennessee ranks among the states with higher rates of alcohol-related emergency department visits and deaths. Shelby County, which includes Memphis, reflects those statewide trends at the local level. The need for accessible, nonstigmatizing treatment is real and persistent.
Serenity Recovery Centers has operated in Memphis since 1971, initially as Serenity House, founded by a group of recovering alcoholics who wanted to build something that didn’t yet exist in their community. More than 15,000 people have completed treatment through Serenity in the decades since. The organization is a nonprofit, funded in part through a grant contract with the Tennessee Department of Mental Health and Substance Abuse Services, and no one is turned away based on inability to pay.
That history and that commitment to access matter specifically in a city where financial barriers and stigma prevent many people from getting the help they need.

Serenity’s admissions team is available to answer questions confidentially, explain what an evaluation involves, and help clarify what level of care makes sense. An addiction evaluation assessment is the right starting point if there’s any uncertainty about the severity of the problem or the appropriate treatment path.
