Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study will evaluate the efficacy and safety of pBFS-guided TMS treatment for the core symptom in autism spectrum disorder children, adolescents and young adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Autism spectrum disorder is a neurodevelopmental disorder characterized by impaired social communication and repetitive behaviors. Broad cognitive control function deficit in ASD suggested cognitive control function as a potential phenotype and treatment target. Using the personalized Brain Functional Sectors (pBFS) technique, investigators could precisely identify individualized brain areas underlying cognitive control function based on the task free functional MRI data. The tailored TMS intervention target to cognitive control function network which located in the left dorsal lateral prefrontal cortex (DLPFC) will be selected for each participant by a blinded researcher.

The participants will be equally randomized to the active iTBS to the cognitive control function network, and sham iTBS at a ratio of 2:1. Each participant will receive 5 days of treatment per week for 12 weeks. Functional MRI data under sedation will be collected pre-and post-treatment. Three behavioral evaluations will be taken pre-treatment, after 8-weeks treatment and after 12-weeks treatment.
