Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition characterized by deficits in social communication, repetitive behaviors, and restricted interests. Effective therapeutic interventions for ASD remain scarce, prompting exploration into novel approaches such as repetitive transcranial magnetic stimulation (rTMS). This study aimed to examine the impact of rTMS intervention on brain structure and function in children with ASD, addressing a gap in correlating neuroimaging changes with behavioral outcomes. Fourteen children diagnosed with ASD participated in an rTMS intervention study. Both neuroimaging data and behavioral assessment scores were collected pre- and post-intervention. Voxel-based morphometry (VBM) and functional connectivity (FC) analyses were conducted to evaluate changes in brain structure and function. Key findings revealed significant increases in gray matter volume (GMV) in the Vermis, Caudate, and Postcentral gyrus, and enhanced FC between Fusiform, Temporal, Frontal, and Precuneus regions following rTMS intervention. Correlation analysis revealed associations between changes in brain structure and function and behavioral scores, suggesting potential therapeutic effects of rTMS on cerebellar development and cognitive control in children with ASD. This study underscores the potential of rTMS as a promising intervention for ameliorating behavioral abnormalities in ASD, supported by its impact on brain structure and function. Further research with larger sample sizes is warranted to validate these findings and elucidate the mechanisms underlying rTMS-mediated improvements in ASD symptoms.
