Internet use and video game playing are experiencing rapid growth among both youth and adult populations. Internet gaming is one of the most popular sources of entertainment for people in all ages, but excess playing this game causes negative consequences including video game addiction. Internet gaming disorder (IGD) is not currently a recognized diagnosis in the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5). However, IGD has been noted to warrant further research for possible future inclusion in the DSM. The excessive usage in the majority of cases was purely symptomatic and was highlighted how the subject used the Internet or computer to counteract other problems. IGD strongly resembles substance and gambling addictions. Such characteristics include tolerance, withdrawal, and social and occupational neglect resulting from increased time invested in video game use and acquisition. We report a case of 20-year old student who used to addict Internet video gaming to counteract his stress and social problem. ARTICLE HISTORY
