How Gambling Disorder Is Classified in Mental Health

Gambling itself is not a mental illness. Millions of people gamble recreationally without it ever becoming a problem. But for some, gambling crosses a line — it becomes compulsive, uncontrollable, and deeply damaging to every area of life. That pattern has a clinical name, and it is recognized as a genuine mental health condition.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association, classifies Gambling Disorder as a behavioral addiction. It sits in the same diagnostic category as substance use disorders — not because gambling involves a chemical substance, but because the brain changes it produces, the loss of control it creates, and the criteria used to diagnose it closely mirror those of substance addiction. This reclassification, which moved gambling disorder out of the “impulse control” category and into “Substance-Related and Addictive Disorders,” was a significant shift in how the medical community understands the condition.

Understanding this distinction matters. Calling someone a “problem gambler” can feel like a moral judgment. Recognizing gambling disorder as a diagnosable mental health condition reframes it accurately — as something that happens to the brain, not a character flaw.

What Happens in the Brain During Compulsive Gambling

The brain’s reward system plays a central role in gambling disorder. When a person gambles, the brain releases dopamine — the same neurotransmitter involved in pleasure, motivation, and reinforcement. In most activities, dopamine is released when a reward is received. In gambling, dopamine is released in anticipation of a reward, even when the outcome is uncertain. That unpredictability actually amplifies the dopamine response.

Over time, the brain adapts. It requires more stimulation to produce the same feeling of excitement. This is why people with gambling disorder often describe needing to bet larger amounts or take bigger risks to feel the same rush they once got from smaller bets. This process — called tolerance — is the same mechanism seen in substance addiction.

Research has also shown structural and functional differences in the brains of people with gambling disorder, particularly in the prefrontal cortex, which governs decision-making, impulse control, and the ability to weigh long-term consequences against short-term rewards. When this region is underactive, the pull toward gambling can override rational thinking even when a person consciously wants to stop.

This neurological reality is why willpower alone is rarely enough. Gambling disorder is not a decision — it is a condition with measurable effects on brain function.

The Relationship Between Gambling Disorder and Other Mental Health Conditions

Gambling disorder rarely exists in isolation. Research consistently shows high rates of co-occurring mental health conditions among people who develop a gambling problem. This relationship runs in multiple directions — some conditions increase vulnerability to gambling disorder, while gambling disorder can also worsen or trigger other mental health symptoms.

Depression and Anxiety

Depression and anxiety are among the most common co-occurring conditions. For someone experiencing depression, gambling can feel like a temporary escape — a way to feel something, to experience excitement, or to numb emotional pain. Anxiety can drive a similar pattern, with gambling serving as a distraction from worry or stress. The problem is that gambling losses tend to intensify both depression and anxiety, creating a cycle that becomes increasingly difficult to break.

Bipolar Disorder

People with bipolar disorder may be particularly vulnerable to gambling disorder during manic or hypomanic episodes. During these periods, impulsivity increases, the need for stimulation rises, and judgment about risk can be significantly impaired. Gambling may feel thrilling and manageable in the moment — and the financial and emotional consequences often become clear only after the episode passes.

ADHD

Attention-deficit/hyperactivity disorder (ADHD) is associated with elevated rates of gambling disorder. The impulsivity that characterizes ADHD can make it harder to pause before placing a bet, and the stimulation of gambling can temporarily satisfy the brain’s need for novelty and engagement. Studies have found that adults with ADHD are more likely to develop gambling problems than those without the diagnosis.

Substance Use Disorders

There is significant overlap between gambling disorder and alcohol and drug use disorders. Both involve the brain’s reward circuitry, and people who struggle with one are at higher risk for the other. Someone in recovery from a substance use disorder may turn to gambling as a substitute behavior — a pattern sometimes called “cross-addiction” — without realizing they are activating the same underlying vulnerability.

When gambling disorder occurs alongside another mental health condition, effective treatment typically needs to address both. Treating only one while ignoring the other often leads to relapse or incomplete recovery.

Signs and Symptoms of Gambling Disorder

The DSM-5 outlines specific criteria for diagnosing gambling disorder. A diagnosis requires that a person exhibit four or more of these behaviors within a 12-month period, and that the gambling causes significant distress or impairment. Recognizing these signs — in yourself or someone you care about — is the first step toward getting help.

• Needing to gamble with increasing amounts of money to achieve the same level of excitement (tolerance)
• Restlessness or irritability when attempting to cut down or stop gambling (withdrawal-like symptoms)
• Repeated unsuccessful efforts to control, cut back, or stop gambling
• Preoccupation with gambling — frequently thinking about past gambling experiences, planning the next session, or thinking about ways to get money to gamble

Beyond the clinical criteria, there are behavioral and emotional patterns that often accompany gambling disorder in everyday life:

• Gambling to escape problems, relieve feelings of helplessness, guilt, anxiety, or depression
• “Chasing losses” — returning to gamble after losing money in an attempt to win it back
• Lying to family members, friends, or therapists to conceal the extent of gambling
• Jeopardizing or losing a significant relationship, job, or educational opportunity because of gambling

Financial warning signs are often among the most visible. These can include borrowing money from family or friends without explanation, taking out loans or cash advances, selling possessions, or accumulating debt that seems disproportionate to income. Some people in the grip of gambling disorder may engage in illegal acts — fraud, theft, or embezzlement — to fund gambling or pay off gambling debts.

One pattern worth understanding is “chasing losses.” Most people, after losing a significant amount of money, would stop. For someone with gambling disorder, a loss can intensify the urge to gamble rather than reduce it. The logic feels compelling in the moment: one more bet might recover everything. This is one of the most recognizable and dangerous features of the disorder.

Who Is at Risk for Gambling Disorder?

Gambling disorder can affect anyone, regardless of age, income, education, or background. However, certain factors are associated with higher risk.

Age plays a role — younger people, particularly adolescents and young adults, are more vulnerable to developing gambling problems. The brain’s prefrontal cortex, which governs impulse control, is not fully developed until the mid-20s, which may partly explain this. Early exposure to gambling — growing up in a household where gambling was common, or starting to gamble at a young age — is also a known risk factor.

Family history matters. People with a parent or sibling who has struggled with gambling disorder or another addiction are at elevated risk, suggesting a genetic component to vulnerability. This does not mean gambling disorder is inevitable for anyone with a family history — but it does mean awareness is especially important.

Mental health history is another significant factor. As discussed above, conditions like depression, anxiety, ADHD, and bipolar disorder are associated with higher rates of gambling disorder. So is a history of trauma or adverse childhood experiences.

The environment matters too. Easy access to gambling — whether through physical casinos, sports betting apps, or online platforms — increases exposure and opportunity. The normalization of gambling in advertising and media, particularly around sports, has made it easier for gambling to become a habitual behavior before warning signs are noticed.

The Difference Between Problem Gambling and Gambling Disorder

These terms are sometimes used interchangeably, but they reflect a spectrum rather than a single category. Problem gambling refers broadly to any gambling behavior that disrupts personal, family, or vocational pursuits — it describes harm without necessarily meeting the full clinical threshold for a diagnosis.

Gambling disorder, as defined by the DSM-5, is the clinical diagnosis at the more severe end of that spectrum. A person can be experiencing significant harm from gambling without meeting all four criteria required for a formal diagnosis. That does not mean their experience is less serious or that they don’t deserve support. It means the spectrum of gambling-related harm is wide, and help is appropriate at any point along it.

If gambling is causing you stress, affecting your relationships, or leading to financial decisions you regret, that is reason enough to reach out. You do not need a formal diagnosis to deserve support.

Treatment Options That Work

Gambling disorder is treatable. Recovery is not only possible — it is common with the right support. Several evidence-based approaches have shown effectiveness, and many people benefit from a combination of treatments tailored to their specific situation.

Cognitive Behavioral Therapy (CBT)

CBT is one of the most well-researched treatments for gambling disorder. It works by identifying and changing the thought patterns that fuel gambling behavior — things like the gambler’s fallacy (believing that a losing streak means a win is “due”), superstitious thinking, and the distorted belief that gambling is a reliable way to solve financial problems. CBT also builds practical coping skills for managing urges, stress, and emotional triggers.

Motivational Interviewing

Motivational interviewing is a counseling approach that helps people explore their own reasons for change. Rather than telling someone they need to stop gambling, a therapist using this approach helps the person clarify their own values and goals — and how gambling conflicts with them. It is particularly useful for people who are ambivalent about whether they have a problem or whether they want to change.

Medication

No medication is currently approved specifically for gambling disorder, but several have shown promise in clinical research. These include opioid antagonists (such as naltrexone), which reduce the rewarding feelings associated with gambling, and certain antidepressants or mood stabilizers, which may be appropriate when gambling disorder co-occurs with depression, anxiety, or bipolar disorder. Medication decisions should always be made in consultation with a qualified healthcare provider.

Financial Counseling and Practical Support

The financial consequences of gambling disorder can be severe and long-lasting. Financial counseling — including debt management, budgeting support, and in some cases, legal guidance — is an important part of recovery for many people. Addressing the practical fallout of gambling alongside the psychological aspects gives recovery a more stable foundation.

Support for Families

Gambling disorder affects entire families, not just the individual who gambles. Family members often experience their own stress, grief, financial hardship, and emotional exhaustion. Family therapy and support resources designed specifically for loved ones of people with gambling disorder can be a critical part of the recovery process — both for the family’s wellbeing and for the person in recovery.

If you are a family member trying to understand what your loved one is going through, or trying to figure out how to help without enabling, confidential support is available to you too. You do not have to navigate this alone.

The Role of Stigma in Delaying Help

One of the most significant barriers to treatment is stigma. Many people with gambling disorder delay seeking help for months or years because they feel ashamed, believe they should be able to stop on their own, or fear judgment from others. This is compounded by the fact that gambling disorder is less visible than some other addictions — there are no obvious physical symptoms, and the financial and emotional damage can be hidden for a long time.

The shame that surrounds gambling disorder is not a reflection of reality. Gambling disorder is a recognized medical condition with identifiable causes and effective treatments. It affects people across every demographic, income level, and walk of life. Reaching out for help is not a sign of weakness — it is the same decision someone would make when dealing with any other health condition that requires professional support.

Language matters here too. Referring to someone as a “compulsive gambler” or implying they simply lack self-control reinforces stigma and can discourage people from seeking help. Person-first language — “a person with gambling disorder” — reflects the medical reality more accurately and treats the individual with dignity.

How to Get Help — For Yourself or Someone You Love

If you recognize the signs of gambling disorder in yourself, the most important thing to know is that you are not alone, and help is available right now. You do not need to wait until things get worse. You do not need to have lost everything. Reaching out at any stage is the right decision.

If you are concerned about someone you love, you may feel uncertain about how to approach the conversation or what kind of support is actually helpful. Speaking with a trained counselor can give you guidance on how to talk to your loved one without pushing them away, and how to take care of your own wellbeing in the process.
