9 For example, abnormal functioning of the ventral medial prefrontal cortex has been associated with gambling and substance addictions, and diminished ventral striatal activation has also been implicated in the cravings associated with gambling and substance addictions. Some evidence from neuroimaging studies supports a shared neurocircuitry of gambling disorder and substance use disorders. 5, 7 – 8 In clinical samples, around 50% of participants with gambling disorder report substance abuse, and up to 63% of individuals seeking treatment for gambling disorder screen positive for lifetime substance use disorder. In addition, there are unusually high rates of co-occurrence between gambling disorder and substance use disorders. 5 For example, many people with gambling disorder report an urge or craving state prior to gambling, as do individuals with substance addictions gambling often decreases anxiety and results in a positive mood state or “high”, similar to substance intoxication and emotional dysregulation often contributes to gambling cravings just as with alcohol or drug cravings. Gambling disorder was relocated because of evidence showing similarities in phenomenology and biology to substance use disorders.
Gambling disorder was formerly listed as pathological gambling in the section on impulse control disorders not elsewhere classified. These disorders are presented in separate sections, but they are not fully distinct because all drugs taken in excess activate the brain’s reward circuitry, and their co-occurrence is common.Īn important departure for DSM-5 from its predecessors was the inclusion of gambling disorder in the chapter on Substance-Related and Addictive Disorders. 6 The DSM-5 specifically lists nine types of substance addictions within this category (alcohol caffeine cannabis hallucinogens inhalants opioids sedatives, hypnotics, and anxiolytics stimulants and tobacco).
ICD 10 CODE FOR PATHOLOGICAL GAMBLING MANUAL
The 5 th Edition of the Diagnostic and Statistical Manual (DSM-5)Īs compared to DSM-IV, the DSM-5’s chapter on addictions was changed from “Substance-Related Disorders” to “Substance-Related and Addictive Disorders” to reflect developing understandings regarding addictions. In addition, this article will suggest some ideas for future research considerations in this field.
This opinion article will review the DSM-5 and proposed ICD-11 changes to the category of substance use disorders and how each has handled the concept of behavioral addictions. 2 – 5 Not surprisingly, both the Diagnostic and Statistical Manual, 5 th Edition (DSM-5) and International Classification of Disease, 11 th Edition (ICD-11) have attempted to address the nosological issue of whether ‘addiction’ should be enlarged to include not just psychoactive substances, but also types of behavior and if so, what types of behavior should be included. In 2001, Constance Holden wrote an article for Science discussing the concept of ‘behavioral addictions’ 1, and since that time, the issue of how best to conceptualize addictions and what to include under the umbrella of addiction has been the focus of considerable research attention. The field of addictions has undergone dramatic changes in recent years.
