Autism spectrum disorder (ASD) is a common and complex neurodevelopmental disorder, which is characterized by impairments of social communication, social reciprocity, as well as restricted and repetitive behaviors (RRB). The unclear pathogenesis of ASD, its increasing prevalence, and its poor clinical diagnosis and treatment effect have caused a serious economic and mental burden on patients and their families. As a new non-invasive neuroelectrophysiological technique, transcranial magnetic stimulation (TMS) has been used more and more in the interventional treatment of autism. The current project aims to explore the influence of TMS on brain plasticity in autism by using TMS for interventional treatment of autism and provide guidelines for the intervention and treatment of autism by evaluating the efficiency of these methods.

The current project aims to explore the influence of TMS on brain plasticity in autism by using TMS for interventional treatment of autism and provide guidelines for the intervention and treatment of autism by evaluating the efficiency of these methods. Investigators conduct a randomized, double-blind, controlled TMS trial and collect the participants' stool samples and sequence the gut microbiome before the first magnetic resonance imaging(MRI) scan. Besides, investigators collect brain imaging data, eye movement data and clinical scale score before and after TMS trial to explore the changes of TMS treatment on clinical behavior and brain plasticity and provide guidelines for the intervention and treatment of autism.

RECRUITINGThe gray matter volume of children with autism at baseline and after repeated transcranial magnetic stimulation intervention as assessed by magnetic resonance imaging.
Longitudinal study of the gray matter volume will be conducted in children with autism at baseline and after repeated transcranial magnetic stimulation intervention based on structural magnetic resonance image. Longitudinal effect of repeated transcranial magnetic stimulation intervention on brain structure in children with autism will be assessed by Voxel-based morphometry analysis for gray matter volume changes.
Time frame: through study completion, an average of 1 year
