rTMS-induced neuroimaging changes measured with structural and functional MRI in autism
Published 2025-05-01“…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. …”
