Gambling disorder involves repeated, problem gambling behavior. The behavior leads to problems for the individual, families, and society. Adults and adolescents with gambling disorder have trouble controlling their gambling. They will continue even when it causes significant problems. Diagnosis A diagnosis of gambling disorder requires at least four of the following during the past year: Need to gamble with increasing amounts to achieve the desired excitement. Restless or irritable when trying to cut down or stop gambling. Repeated unsuccessful efforts to control, cut back on or stop gambling. Frequent thoughts about gambling (such as reliving past gambling or planning future gambling). Often gambling when feeling distressed. After losing money gambling, often returning to get even. (This is referred to as “chasing” one’s losses.) Lying to hide gambling activity. Risking or losing a close relationship, a job, or a school or job opportunity because of gambling. Relying on others to help with money problems caused by gambling People with gambling disorder can have periods where symptoms subside. The gambling may not seem a problem in between periods of more severe symptoms. Gambling disorder tends to run in families. Factors such as trauma and social inequality, particularly in women, can be risk factors. Symptoms can begin as early as adolescence or as late as older adulthood. Men are more likely to start at a younger age. Women are more likely to start later in life.
