This suggests that hormone-activated alterations in widespread brain networks, such as attention network, can contribute to the pathophysiology of the disorder in girls, while distinct mechanisms may exist in boys. This study proposed to examine the topological properties and their temporal dynamics of the sustained attention network in preadolescent children with binge eating symptoms (BE) and matched controls and to test the relation of these properties to circulating levels of pubertal hormones. Data from 77 children with BE and 104 group-matched controls were analyzed. In a static network comprising the entire task duration, the nodal topological properties, i.e., nodal efficiency, betweenness-centrality and degree, of the caudate nucleus, hippocampus and inferior parietal gyrus (IPG) significantly differentiated children with and without BE; and that of left caudate were significantly associated with pubertal hormone levels in girls with and without BE, but not in boys. During different substages of sustained attention processing, Variability of the topological properties in key network nodes, such as bilateral IPG, bilateral precentral gyrus and left hippocampus, demonstrated significant between-group differences and/or unique group-by-sex interactions. These results suggest that the association between pubertal hormones and network topological organization may contribute towards the specific rise of BE in girls, while neural mechanisms of BE in boys may alternatively link to suboptimal functional dynamics associated with precentral gyrus, during their interactions with other cortical and subcortical regions when sustained attention is |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n|  |  |  |\n| performed. |  |  |\n|  | Translational Psychiatry (2026)16:5; [https://doi.org/10.1038/s41398-025-03756-y](https://doi.org/10.1038/s41398-025-03756-y) |  |\n|  |  |  |\n\nINTRODUCTION  \nBinge eating disorder (BED) is the most common eating disorder, affecting 1.1% of children and between 1 and 5% of adolescents [1, 2]. The risk for problematic binge eating (BE) increases from late childhood to early adolescence [1, 2], coincident with the pubertal surge of gonadal hormones [3] and may serve as a vulnerability for eating disorders in later life [4, 5] . However, the elevated risk is not spread uniformly, with a significantly greater increase in prevalence of BE during puberty in girls than boys [6] . This suggests that different neural developmental effects and pubertal hormones, as well as their distinct interactions, may be implicated in the pathophysiology of BE in boys and girls.  \nWidespread neural alterations have been identified in individuals with BE [7] . These include distinct patterns of dysconnectivity among distant brain regions or systems-level alterations of the functional brain networks subserving cognitive processes and/or at resting-state [8–11] . Several cognitive processes believed to be involved in BE, including attention, are supported by these widespread brain pathways and rely heavily on the maintenance of arousal [12–14] . Generalized brain arousal, which increases the excitation and activation of attention and behavior, may be implicated in these functional alterations [15] .  \nThe link between the pubertal hormone surge and generalized arousal has been established ","cbCaigYz7k7zXUEs","https://ap.wps.com/l/cbCaigYz7k7zXUEs","pdf",1494864,"English","# Introduction\n## Puberty-linked binge eating risk and sex differences\n## Brain network alterations in binge eating disorder\n## Pubertal hormones, arousal, and attention networks\n# Study Rationale and Aims\n## Systems-level topology and temporal dynamics in children\n## Linking network properties to pubertal hormone levels","[{\"question\":\"How does puberty relate to binge eating risk in boys and girls?\",\"answer\":\"The study background states that binge eating risk increases from late childhood to early adolescence and rises more during puberty in girls than boys.
