| Summary: | Many studies on the neurological foundations of Internet Gaming Disorder (IGD), which is on the increase and is characterized by excessive online gaming that significantly impairs life, have been inspired. Insights from Functional Magnetic Resonance Imaging (fMRI) research on IGD are summarized in this abstract. These investigations have shed light on the complex interactions between brain mechanisms involved in the processing of rewards, impulse control, cognitive flexibility, withdrawal, and desire. The dopamine-driven reward system reacts strongly to inputs associated to gaming, thereby strengthening the addictive loop. Changed patterns of activation in areas related to flexibility, decision-making, and impulse control point to challenges in regulating gaming behavior and shifting concentration. The extensive impact of IGD on brain functioning is highlighted by the disruption of connections among brain networks responsible for emotional regulation, cognitive control, and reward processing. The fMRI activity during gaming cessation shows withdrawal symptoms and desire, similar to drug use disorders. Together, these discoveries provide a multifaceted knowledge of the neurological underpinnings of IGD, paving the way for focused therapies and all-encompassing approaches to deal with this contemporary behavioral dilemma. It is hoped that as research advances, the blending of neurobiological understandings with larger contextual elements may reveal ways to encourage healthy digital participation and mental wellbeing in the digital era.
