The article discusses modern approaches to classification of nonchemical (behavioral) addictions on the example of Internet addiction (IA). The discussion around the inclusion of gaming disorders, including those implemented via the Internet in ICD-10 is analyzed. The general neurobiological and genetic mechanisms of the formation of all addictive disorders, both chemical and non-chemical, are shown. In order to develop standardized approaches to the treatment of IA, one should first of all determine which forms are nosological units - a disorder - according to the criteria of the ICD and DSM and on this basis to conduct evidence-based studies of the effectiveness of various therapeutic methods. In the course of the discussion, it is concluded that various forms of deviations and disorders can be called «fake», but nevertheless they will not disappear and people will not stop suffering from them.
