"One level more:" A narrative review on internet gaming disorder

Due to explosive growth in technology and internet usage in the last few years, internet gaming disorder (IGD) has manifested as rapidly growing public health problem mainly affecting the teen and preteen population worldwide. It has a negative impact upon physical, psychological, social, and occupational functioning of the affected individual, often leading to severe consequences. It was only recently that it has been recognized as a separate diagnosable disorder in the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition. Not much data is available regarding the exact prevalence and the various sociodemographic, clinical, and other risk factors to identify the individuals vulnerable to develop this disorder, especially in the developing countries such as India. According to a recent report, India ranks 22 in the list of highest revenue-generating countries from gaming-related businesses, thus highlighting the magnitude of risk faced by Indian population. The aim of this review is to provide an insight about the disorder to identify the risk factors and clinical features, to understand the effect of IGD upon the psychological and physical health with a special focus on neural changes, and to provide information on the various upcoming preventive and treatment strategies.
