An observational study in Autism Spectrum Disorder (ASD), sponsored by Guangzhou Women and Children's Medical Center. Recruiting at 1 site in China. Open to male participants aged 6 Years to 12 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-07-15.
Sponsored by Guangzhou Women and Children's Medical Center · Observational
The goal of this observational study is to learn how brain activity in children with autism spectrum disorder (ASD) differs from typical developing children using magnetoencephalography (MEG).
The main questions this study aims to answer are:
Do children with ASD show different patterns of neural oscillation compared to typically developing children? Can MEG identify specific brain features that help ASD diagnosis?
Participants will undergo MEG scan in both resting and tasking state, and their brain activity will be analyzed for characteristic neural oscillations and connectivity patterns.
This study may help develop better tools for early ASD diagnosis.

Exclusion Criteria:
Participants in the ASD group consisted of children diagnosed with Autism Spectrum Disorder according to DSM-5 criteria.
Diagnostic Test: Magnetoencephalography
Participants in the Control group consisted of typically developing children.
Diagnostic Test: Magnetoencephalography
Participants will undergo magnetoencephalography scan in both resting and tasking state.
Identification of Neural Oscillation Characteristics in Children with Autism Spectrum Disorder
The primary outcome will measure group differences in neural oscillation features (e.g., spectral power and spatial distribution) across frequency bands (alpha, beta, gamma) between children with Autism Spectrum Disorder and typically developing children during resting-state and task-based conditions. Quantified using time-frequency analysis of magnetoencephalography data. Statistical analysis will include independent t-tests (or Mann-Whitney U tests for non-normally distributed data) with false discovery rate (FDR) correction, using SPSS version 27.0.
Time frame: Baseline assessment (single time point, within 1 week of enrollment).
