The activity of play has been ever present in human history and the internet has emerged as a new popular playground for most of the children and youth. As research suggests that a minority of internet game players experience symptoms traditionally associated with substance-related addictions, the fifth revision of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) includes a condition known as Internet Gaming Disorder (IGD) in Section III, “Conditions for Further Study.” Although IGD has become a popular topic for researchers, still little is known about it. The aim of this review is to present a case of 12-year-old boy referred to our clinic as a judicial case and diagnosed as IGD and comorbid depression and to summarize the available data about the prevalance, risk factors, course and treatment of the disorder upon this case.
