Neuroimaging has continually advanced, playing a crucial role in the accurate diagnosis of various brain pathologies and disorders. This integrative review aimed to identify the main changes in brain connections found in fMRI scans of individuals with Internet Gaming Disorder (IGD). The data collection method involved searching for the terms "Magnetic Resonance Imaging", "Psychological Dependence" and "Internet Addiction Disorder" in the PubMed and Embase databases. Studies published between 2020 and January 2023 were included and manually analyzed through the virtual environment created in the "Rayyan" software, compiling a total of 18 scientific studies. The main findings reveal changes such as significant increases or decreases in functional connectivity in certain regions of the brain. Some potential negative impacts on the uncontrolled use of technologies among the young population were evaluated, such as the loss of inhibitory control in decision-making, transforming leisure into dependence, and although the IGD understands the associated risks and harms, it faces difficulties in resisting the desire to stop playing. This situation emphasizes the need for more long-term studies that can be comparative between different age groups. Conclusion, the brain regions with the most significant changes in functional connectivity in individuals with IGD symptoms are the prefrontal cortex, fronto-parietal regions, frontal gyrus, insula lobe, cingulate cortex and striatum. The lack of comprehensive knowledge about the effects of video game addiction across different age groups is a significant concern. Therefore, it is essential to carry out research that evaluates the impact of these technologies on different stages of human development.
神经影像学不断发展，在各种脑部病变和疾病的准确诊断中发挥着关键作用。本综合综述旨在确定在患有网络游戏障碍（IGD）的个体的功能磁共振成像（fMRI）扫描中发现的脑连接的主要变化。数据收集方法包括在PubMed和Embase数据库中搜索“磁共振成像”、“心理依赖”和“网络成瘾障碍”等术语。纳入了2020年至2023年1月发表的研究，并通过“Rayyan”软件创建的虚拟环境进行人工分析，共汇编了18项科学研究。主要发现揭示了一些变化，例如大脑某些区域的功能连接显著增加或减少。评估了对年轻人群不受控制地使用技术的一些潜在负面影响，例如决策中抑制控制的丧失、将休闲转变为依赖，以及尽管IGD了解相关风险和危害，但在抵制停止游戏的欲望方面面临困难。这种情况强调需要进行更多可在不同年龄组之间进行比较的长期研究。结论，有IGD症状的个体中功能连接变化最显著的脑区是前额叶皮质、额顶叶区域、额回、脑岛叶、扣带回皮质和纹状体。缺乏关于不同年龄组视频游戏成瘾影响的全面知识是一个重大问题。因此，开展评估这些技术对人类发育不同阶段影响的研究至关重要。
