Towards an accurate autism spectrum disorder diagnosis: multiple connectome views from fMRI data.

The study introduces a novel approach for diagnosing autism spectrum disorder (ASD) by integrating multiple brain connectivity patterns derived from functional magnetic resonance imaging (fMRI) data. Traditional methods have been limited by focusing on single connectivity patterns, such as full correlation, partial correlation, or causality, which may overlook complementary topological information. This research proposes the use of kernel combination techniques to merge different connectivity patterns, aiming to enhance diagnostic accuracy for neurological disorders like ASD.
Importance: The method addresses the limitations of previous studies by capturing a more comprehensive picture of the brain’s functional connectome, potentially leading to better diagnostic tools for ASD.
Contribution: The study contributes to the current literature by demonstrating the effectiveness of combining multiple connectivity patterns for ASD diagnosis, which is a significant advancement over single-pattern approaches.
Results: The proposed method was tested on the Autism Brain Imaging Data Exchange dataset, yielding high diagnostic performance with an accuracy of 91.30%, sensitivity of 91.48%, and specificity of 91.11%. These results suggest that the method could be a powerful tool for accurate ASD diagnosis.
