This study developed a novel multi-metric electroencephalography (EEG) framework to analyze neural oscillations in autism spectrum disorder (ASD). The integrated approach significantly improved ASD classification accuracy, offering potential for clinical diagnosis.

Area of Science:

  • Neuroscience
  • Biomedical Engineering
  • Computational Psychiatry

Background:

  • Traditional electroencephalography (EEG) analysis methods have limitations in characterizing the complex neural features of autism spectrum disorder (ASD).
  • A novel multi-metric EEG framework was developed to integrate temporal, spectral, and spatial dimensions for a comprehensive analysis of neural oscillations in ASD.
  • This framework aims to systematically characterize the dynamics, individualization, and nonlinear network features of neural oscillations in ASD.

Purpose of the Study:

  • To develop and evaluate a multi-metric EEG framework for characterizing neural oscillations in children with ASD.
  • To investigate the temporal, spectral, and spatial dynamics of neural oscillations in ASD using advanced analytical methods.
  • To assess the classification performance of integrated multidimensional EEG features for ASD diagnosis.

Main Methods:

  • Resting-state EEG data were collected from children with ASD (n=44) and typically developing (TD) children (n=44).
  • Temporal analysis used Lempel-Ziv complexity (LZC) for signal dynamic complexity.
  • Frequency domain analysis employed the gedBounds method for individualized frequency band identification.
  • Spatial domain analysis utilized Generalized Symbolic Nonlinear Granger Causality (GSNGC) for brain functional network construction and graph-theoretic metrics.
  • A support vector machine (SVM) integrated multidimensional features for ASD classification.

Main Results:

  • The ASD group exhibited significantly lower whole-brain LZC, particularly in the alpha band, indicating reduced neural dynamic information processing capacity.
  • Frequency domain analysis revealed an expanded theta bandwidth, reduced low-frequency power in central-occipital regions, and increased beta power in frontal regions in the ASD group.
  • Spatial analysis showed atypical connectivity patterns in ASD, including increased low-frequency and beta-band connectivity, reduced alpha-band connectivity, and higher global efficiency in theta and beta networks.
  • The SVM model integrating temporal, frequency, and spatial features achieved 89.2% accuracy, outperforming single-domain feature models.

Conclusions:

  • The study introduces a novel analytical approach combining individualized frequency band identification, nonlinear connectivity modeling, and dynamic complexity analysis.
  • Findings reveal multi-scale abnormalities in neural oscillations in children with ASD.
  • Multi-dimensional EEG feature integration demonstrates significant discriminative power for ASD classification and auxiliary diagnosis, providing a basis for clinical intervention.
