Gambling disorder — also referred to as pathological gambling or compulsive gambling — is a psychiatric condition characterised by persistent and recurrent problematic gambling behaviour that causes significant impairment or distress. It is classified in DSM-5 as a non-substance addictive disorder and in ICD-11 under disorders due to addictive behaviours — reflecting the recognition that gambling disorder shares the neurobiological, psychological, and clinical features of substance use disorders, without involving any psychoactive substance.
The inclusion of gambling disorder within the addiction framework reflects decades of research demonstrating that pathological gambling activates the same reward circuitry, produces the same patterns of tolerance and craving, generates the same cycles of loss of control and relapse, and causes the same devastating functional consequences as substance addictions — through psychological and neurobiological mechanisms rather than pharmacological ones.
Gambling disorder is not about gambling too much. It is about a relationship with gambling that has acquired the characteristics of addiction: preoccupation, loss of control, escalation, continued behaviour despite severe negative consequences, and failed repeated attempts to stop.
The diagnostic criteria include persistent preoccupation with gambling; the need to gamble with increasing amounts of money to achieve the desired excitement — analogous to tolerance in substance addiction; repeated unsuccessful efforts to control or stop; restlessness or irritability when attempting to reduce gambling; gambling as a means of escaping problems or relieving dysphoric mood; chasing losses — returning after losing money to recoup; lying to conceal the extent of gambling; jeopardising significant relationships or employment; and reliance on others to resolve desperate financial situations caused by gambling.
The disorder is not defined by the amount wagered or frequency of gambling, but by the degree to which gambling has acquired compulsive, uncontrollable qualities and is causing significant harm.
The neurobiological parallels with substance addiction are well-established. Gambling activates the dopaminergic reward system in ways that closely parallel addictive substances. Individuals with gambling disorder show reduced activation in prefrontal areas associated with inhibitory control and heightened reactivity to gambling-related cues. These are not psychological weaknesses — they are measurable neurobiological differences in how the brain processes reward, risk, and loss.
The near-miss effect — the way gambling machines are designed to produce outcomes that feel close to winning — is a particularly potent trigger, activating the reward system similarly to an actual win.
Gambling disorder has very high rates of psychiatric comorbidity. Depression is extremely common — both as a consequence of the losses that gambling produces and as a co-occurring condition to which gambling may have served as self-medication. Anxiety disorders, PTSD, ADHD, substance use disorders, and personality disorders are all significantly elevated in prevalence.
Suicidality is an important clinical concern. The combination of severe financial losses, shame, damaged relationships, and hopelessness produces a significant risk profile requiring ongoing clinical attention.
Assessment includes a comprehensive psychiatric interview exploring the history, pattern, and severity of gambling behaviour; full evaluation of psychiatric comorbidities — particularly depression, anxiety, PTSD, ADHD, and substance use; assessment of functional impact — financial, relational, occupational; and risk assessment including suicidality.
A thorough clinical formulation — understanding what function the gambling serves for this specific individual — is the foundation of effective treatment.
Cognitive Behavior Therapy (CBT) adapted for gambling disorder is the gold-standard psychological treatment. CBT addresses the cognitive distortions that maintain the disorder — the gambler's fallacy, illusions of control, misinterpretation of near-misses — alongside the behavioural patterns, emotional triggers, and coping deficits that drive continued gambling.
Motivational approaches are important in the earlier stages — building and sustaining motivation for change and addressing ambivalence.
Addressing underlying psychiatric conditions — depression, anxiety, PTSD, ADHD — is a critical component. Treating these alongside gambling disorder produces substantially better outcomes than treating either in isolation.
The financial and relational consequences are often severe and require practical support alongside clinical treatment. At IsraClinic, we work with the full picture — not only the psychiatric dimension.
Pharmacotherapy — opioid antagonists, SSRIs, and mood stabilisers — has a developing evidence base and may be indicated in specific presentations or where comorbid conditions require pharmacological management. Medication is prescribed individually. Digital prescriptions are issued through the Yarpa system.
All treatment is delivered within the framework of the Psychoergonomic Method.
If gambling is consuming increasing amounts of time and money, if repeated attempts to stop have failed, if gambling is causing significant damage to finances, relationships, or work, or if you are experiencing significant distress or hopelessness related to gambling — professional assessment is appropriate.
IsraClinic accepts patients for in-person consultation in Tel Aviv and online, in English, Russian and Hebrew. No referral is required.
