Internet gaming and related psychotic disorder: An emerging phenomenon.

Internet addiction has recently been suggested as a possible diagnostic entity in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and incorporated in the International Classification of Diseases 11 Revision (ICD-11) as a gaming disorder, predominantly, online or offline. Mostly, psychotic phenomena have been described by either alcohol or opioid withdrawal, but there is a paucity of literature on Internet-related psychosis. We report two cases from Northern India of sudden onset of psychosis due to Internet addiction. The contents of hallucinations and delusions reflected themes of Internet gaming. Psychosis as a specifier for Internet gaming disorder (IGD) is not defined in DSM-5, whereas it should be considered as one of the presentations of Internet addiction.
