Abstract

The Internet now plays a very important role in our lives. However, for some people, Internet use can lead to a state that appears to meet the DSM definition for a mental disorder. In this review, we briefly discuss definition, symptoms, risk factors, prevalence, comorbidities, and personality traits of people who are susceptible to becoming addicts. In the second section of the article, various types of Internet addiction are discussed, focusing mainly on Internet Gaming Disorder and social networking survices (SNS) addiction. Regarding Internet Gaming Disorder, we discuss various types of the newly emerged Massive Multiplayer Online Games (MMO), as well as theories about why people become addicted to them. We do the same for the SNS Addiction for sites like Facebook and LINE; again, different types, as well as theories about why some people become addicts to such sites are discussed. Finally, preventive measures are introduced, focusing on a number of commonly used treatment methods, perticulary cognitive behavioral therapy and family therapy.
