Previous studies using voxel\u2010based morphometry (VBM) or surface\u2010based morphometry (SBM) have identified regional alterations in grey matter volume and cortical thickness (CT); purely local morphological analyses are insufficient to capture coordinated patterns of interregional change. In this study, we employed structural covariance networks (SCNs) analysis to investigate abnormalities in the macroscopic topological organization of the brain in individuals with CUD, based on CT measures. A total of 68 patients with CUD and 52 healthy controls (HCs) were included from the OpenNeuro database. The results demonstrated that the CUD group exhibited a significantly reduced global clustering coefficient and a shift in small\u2010world properties, with network topology becoming more closely aligned with a lattice\u2010like configuration. In addition, CUD showed disrupted rich\u2010club connectivity, particularly within core frontoparietal regions. Notably, no significant group differences were observed in network robustness against random failure or targeted attack. Together, these findings indicated an imbalance between network integration and segregation in the structural brain networks of individuals with CUD, providing a novel network\u2010level perspective on the pathophysiology of addiction and suggesting potential utility as a diagnostic neurobiological marker.<\/jats:p>","DOI":"10.1111\/adb.70176","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T13:14:21Z","timestamp":1782479661000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Abnormal
