Gambling disorder

Symptoms and key features

The American Psychiatric Association defines gambling disorder as four or more of these in a 12-month period, as summarized by MedlinePlus:

• needing to bet more and more money to feel the same excitement
• feeling restless or irritable when trying to cut back or stop
• repeated, unsuccessful attempts to cut back or quit
• spending a lot of time thinking about gambling or how to get money for it
• gambling to escape stress, sadness, or anxiety
• going back to win back losses ("chasing")
• lying about how much time or money goes to gambling
• losing or risking a job, relationship, or opportunity because of gambling
• needing others to bail you out financially

What it looks like

A 34-year-old nurse started with sports betting on his phone during the pandemic. At first it was a few dollars on weekend games. Now he bets on overseas basketball at 3 a.m., has a second credit card his wife doesn't know about, and took a payday loan to cover rent. Each loss makes him more certain the next bet will fix it. He's deleted the app four times and reinstalled it within a day each time.

Phones changed this. Betting apps and online casinos are open every hour, and there's no walk to the casino to give you a moment to reconsider. People often describe it as a trance: hours disappear, and the goal shifts from winning to just staying in the game.

What people often confuse this with

Recreational gambling. Plenty of people gamble for fun and stop at a set limit. The line is crossed when gambling is controlling the person, not the other way around.

Mania. Reckless betting during a manic episode is part of bipolar disorder. If gambling only happens during mania, the mania is the main thing to treat.

Medication side effects. Some people taking dopamine agonist drugs, like pramipexole for Parkinson's disease or restless legs syndrome, develop new gambling problems or other compulsive urges. That needs a conversation with the prescriber, not just willpower.

OCD. MedlinePlus notes compulsive gambling shares some features with OCD but is likely a different condition. Gambling is usually driven by reward and excitement, OCD by anxiety relief.

What research says

• CBT works in the short term. A Cochrane review of 14 trials found CBT had beneficial effects right after treatment, ranging from medium (money lost) to very large (symptom severity). Only one trial looked at 9 to 12 months, so how long the gains last is less certain.
• It's common and often missed. The 2019 review in Nature Reviews Disease Primers estimates prevalence at about 0.5 percent of US adults, and notes most people go unrecognized and untreated, even in clinical settings.
• It's linked to suicide. The same review cites links to poor quality of life and suicide, which is why screening matters.
• Relapse is common. MedlinePlus describes it as a long-term condition where returning to gambling is common, and where people can still do very well with the right treatment.
• Health systems are catching up. The UK's NICE guideline on gambling-related harms (NG248) sets out how clinicians should identify, assess, and treat it.

How it's diagnosed

A clinician diagnoses gambling disorder with a careful interview about gambling habits, money, and consequences, and checks the DSM-5-TR criteria above. Screening questionnaires, like the Gamblers Anonymous 20 Questions, can prompt the conversation. DSM-5 moved gambling disorder into the same chapter as substance use disorders, reflecting research on shared brain reward pathways.

A good evaluation also asks about:

• depression, anxiety, and suicidal thoughts
• alcohol and drug use
• bipolar disorder, since heavy gambling can happen during mania
• ADHD and other impulsivity
• debts, legal problems, and who else is affected

Why it happens

MedlinePlus explains that gambling triggers a dopamine surge, much as certain drugs do, and in people who develop the disorder, occasional gambling turns into a habit. It most often starts in early adolescence in men and later in women. A 2019 clinical review describes a mix of genetic and environmental factors and changes in the brain's reward and control circuits. MedlinePlus adds that stressful situations can make gambling problems worse.

Treatment

Cognitive behavioral therapy. CBT targets the thinking traps that keep gambling going: the belief that a win is "due," near misses feeling like almost winning, and chasing losses. It also builds a plan for urges and high-risk moments. It has the strongest evidence.

Motivational interviewing. Short conversations that help a person weigh the costs and decide for themselves what to change. Useful when someone isn't sure they want to stop.

Support groups. Gamblers Anonymous is a 12-step program. Gam-Anon supports family members. Many people find them useful alongside therapy.

Medication. No medication has a formal approval for gambling disorder. The opioid blocker naltrexone has shown promise in placebo-controlled trials, as the 2019 review notes. See the naltrexone guide on PsychiatryRx. Treating co-occurring depression, anxiety, or ADHD matters too.

Money safeguards. Handing control of finances to a trusted person for a while, blocking gambling transactions at the bank, installing blocking software, and self-excluding from casinos and betting sites all put distance between the urge and the bet. They aren't treatment on their own, but they protect recovery.
