The extent to which non-substance-related behaviors like gambling or Internet use may be best considered within an addiction framework has been debated. In DSM-5, pathological gambling (now gambling disorder) was reclassified together with substance-use disorders into a “Substance-related and Addictive Disorders” category. This reclassification, based on data from multiple domains (including neurobiological) that emerged during the time of DSM-IV, represents an important step forward. In this presentation, neurobiological similarities between substance-use and gambling disorders involving cortico-striatal functions will be discussed. Data from studies of Internet-gaming disorder (and more broadly problematic Internet use) will also be discussed, as will models linking the neurobiological data to psychological constructs proposed as being central to addictions. Implications for classification, policy, prevention and treatment development will be presented
