Autism Spectrum Disorder

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy

Modeling in Therapy

Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.
Participant Modeling
Participant modeling involves therapists demonstrating calm and effective behaviors in...

Background:

Autism Spectrum Disorder (ASD) recognition is challenging due to symptom heterogeneity and complex brain variations.
Resting-state functional magnetic resonance imaging (rs-fMRI) reveals abnormal neural activity and connectivity in ASD.
Existing deep learning methods for fMRI often use single representational scales, ignoring dynamic network reconfiguration and multi-atlas variations.

Purpose of the Study:

To develop a novel deep learning framework for improved ASD recognition.
To capture spatiotemporal dynamics and multi-atlas functional connectivity variations in brain networks.
To create an interpretable model for identifying ASD biomarkers.

Main Methods:

Proposed a Multi-Atlas Dynamic Connectivity Transformer fused with 4D Spatiotemporal modeling (MADCT-4D) for ASD recognition.
Employed two branches: a 4D spatiotemporal branch for evolving neural activity and a dynamic-connectivity branch for time-resolved functional connectivity sequences across multiple atlases.
Utilized late fusion with a learnable gate to adaptively weight voxel-level dynamics and multi-atlas connectivity evidence.

Main Results:

Achieved 90.2% accuracy in ASD recognition on the ABIDE dataset.
Outperformed multiple competitive baseline methods in classification accuracy.
Demonstrated the model's ability to capture dynamic reconfiguration at the connectome level across different parcellation granularities.

Conclusions:

The MADCT-4D framework provides a robust method for ASD recognition.
The model yields interpretable biomarkers based on dynamic connectivity patterns.
These learned patterns align with known alterations in functional coupling associated with ASD.
