Abstract
Background
The morphometric inverse divergence (MIND) method offers a reliable approach for constructing structural similarity networks. While studies have identified abnormal connectivity in functional networks in internet gaming disorder (IGD), its MIND network pattern alterations remain unclear.
Methods
We analyzed 110 IGD individuals and 158 recreational gaming users (RGU), constructing MIND-based networks. We compared mean differences across large-scale sub-networks and individual regions. We also conducted edge analysis to identify subtle changes in individual connections. Additionally, we examined topological properties, including small-worldness, efficiency, and nodal centrality.
Results
Individuals with IGD exhibited increased similarity between the visual and ventral attention/salience networks (Five significant edges), which was positively correlated with IGD severity. Additionally, several strengthened connections were identified, involving the default-sensorimotor and default-visual networks. Network topology analysis revealed a significant reduction in normalized characteristic path length in IGD (t = 2.357, p = 0.019), which may indicate a shift towards a more randomized brain network topology. Further, nodal centrality was also elevated (p < 0.001, uncorrected) in the same regions, including the visual, attentional, and prefrontal regions, showing a positive association with IGD severity.
Conclusion
Our findings revealed that excessive online gaming alters increased the similarity between the visual and attention network and increases nodal centrality in these regions, offering new insights into the neuroanatomical mechanisms underlying IGD.
期刊介绍:
Addictive Behaviors is an international peer-reviewed journal publishing high quality human research on addictive behaviors and disorders since 1975. The journal accepts submissions of full-length papers and short communications on substance-related addictions such as the abuse of alcohol, drugs and nicotine, and behavioral addictions involving gambling and technology. We primarily publish behavioral and psychosocial research but our articles span the fields of psychology, sociology, psychiatry, epidemiology, social policy, medicine, pharmacology and neuroscience. While theoretical orientations are diverse, the emphasis of the journal is primarily empirical. That is, sound experimental design combined with valid, reliable assessment and evaluation procedures are a requisite for acceptance. However, innovative and empirically oriented case studies that might encourage new lines of inquiry are accepted as well. Studies that clearly contribute to current knowledge of etiology, prevention, social policy or treatment are given priority. Scholarly commentaries on topical issues, systematic reviews, and mini reviews are encouraged. We especially welcome multimedia papers that incorporate video or audio components to better display methodology or findings.
Studies can also be submitted to Addictive Behaviors? companion title, the open access journal Addictive Behaviors Reports, which has a particular interest in ''non-traditional'', innovative and empirically-oriented research such as negative/null data papers, replication studies, case reports on novel treatments, and cross-cultural research.
