Abstract:

Background and Aim : Internet addiction disorder (IAD) is defined as excessive usage of internet leading to significant psychological, social, and/or work difficulties. It is well known that IAD is related to various comorbid psychological conditions, such as depressed mood and anxiety, as well as psychiatric disorders, including attention deficit hyperactivity disorder and obsessive-compulsive disorder. The purpose of this study was to identify the most significant Event Relate Potential (ERP) components of people with Internet addiction to better understand the neuroimaging markers of the disorder. Identification of the neuroimaging markers of the Internet addiction may lead to clarification of its etiology.Methods : Scopus, Google scholar and PubMed databases were used for literature review. The keywords included Internet Addiction , ERP, Task and Problematic Internet Use . Seventy-seven papers which are written in English and have been published since 2010 are reviewed. Articles were categorized according to the ERP tasks and ERP components.Results : From seventy-seven studies fifty-five of them were excluded from the study due to: thirty-four of them were Internet Gaming Disorder. Five of them didn’t include any ERP tasks. Two of them investigated online shopping addiction, two studies had therapeutic intervention. Five studies were explored smartphone abuse (non-internet addicts). Two of them were fMRI studies and five studies only had behavioral tasks and no imaging techniques were used. At the end, twenty-two studies remained for further analysis.Conclusion : According to the statistical significance of the remaining papers, N2 and P300 amplitudes are significantly different between IAD subjects and healthy controls. Also, the most applied task which demonstrates significant alteration in these amplitudes was Go/NoGo decision making task. In conclusion, N2 and P300 alterations could be considered as two endophenotypes associated with internet addiction disorder.
