Gaming over the internet is one of the major interests in children and
adolescents. Nowadays, a wide range of games are available on the internet ranging
from casual browser games, multiplayer games, and simulator-based games, etc. This
advanced gaming technology allowed players to connect with each other virtually
through their social connection. However, excessive internet gaming leads to functional
and structural changes in the brain areas. Thus behavioural changes are noticed
commonly in the new generation. They are moving from real-life social relations to
online social sites, and when this movement is uncontrolled by self-restriction or not
limited by supervision gradually turns into online addiction. The World Health
Organization (WHO) has recognized Internet Gaming disorder (IGD) as a diagnosable
condition and decided to include it in the “International Classification of Diseases
(ICD)” 11th edition in the year 2018. Such online gaming addiction study is gaining
interest in clinicians and researchers, making it an active area of research. The study of
its symptoms and its assessment methods for detecting and analyzing internet gaming
addiction is the need of the hour. In this paper, an extensive study about Internet
Gaming Disorder and its assessment methods was presented. Examination of IGD in
participants using different modalities ranging from self-reported psychological
questionnaires-based assessment to pathological neuroimaging methods to multimodal
biosignal analysis is discussed and analysed. Comparative analysis of modalities has
also been performed in order to summarize findings in terms of efficiency, mobility,
and availability. The analysis presented in this paper will be useful for the researchers
for developing an effective computational method for IGD analysis.
