rTMS-induced neuroimaging changes measured with structural and functional MRI in autism by Xiaodong Kang, Kai Chen, Fei Wang, Linyi Mu, Zengzhen Lei, Rufei Zhang, Zedong Wang, Tao Zhang, Tao Zhang

“…Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising non-invasive neuromodulation technique; however, its neural mechanisms and clinical efficacy in children with ASD require further investigation.MethodsThis study enrolled 14 children diagnosed with ASD to undergo a structured rTMS intervention. Neuroimaging data—including voxel-based morphometry (VBM) and resting-state functional connectivity (FC)—as well as behavioral assessments were collected before and after the intervention to evaluate changes in brain structure, function, and symptomatology.ResultsPost-intervention analyses revealed significant increases in gray matter volume (GMV) in the cerebellar Vermis, Caudate nucleus, and Postcentral gyrus. …”
