Prosopagnosia

Prosopagnosia

Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...

Area of Science:

Neuroscience
Machine Learning
Medical Informatics

Background:

Brain functional network (BFN) analysis is crucial for early neurological disease detection and biomarker discovery.
Graph convolutional networks (GCNs) show promise for BFN analysis but require substantial training data, which is often scarce in clinical settings.
Limited data leads to GCNs failing to learn reliable representations and causing overfitting, hindering accurate disease classification.

Purpose of the Study:

To propose an improved GCN method incorporating a self-supervised learning (SSL) module to enhance graph feature representation.
To address the challenge of limited brain functional data in classifying neurological disorders.
To improve the accuracy of classifying mild cognitive impairment (MCI) and autism spectrum disorder (ASD) from normal controls (NCs).

Main Methods:

Developed an improved GCN architecture integrated with a self-supervised learning (SSL) module.
Utilized SSL to assist in learning robust graph feature representations from limited BFN data.
Conducted classification experiments on two benchmark databases for MCI vs. NC and ASD vs. NC.

Main Results:

The proposed SSL-assisted GCN method demonstrated higher classification accuracy compared to baseline GCN methods.
The approach effectively mitigates overfitting issues associated with limited training data in BFN analysis.
Experimental results validated the efficacy of the proposed scheme on benchmark datasets for neurological disorder classification.

Conclusions:

The integration of SSL with GCNs offers a promising solution for accurate brain disease classification using limited BFN data.
This method enhances the reliability of feature representation, leading to improved diagnostic capabilities for neurological conditions.
The findings suggest a potential advancement in early detection and biomarker identification for diseases like MCI and ASD.
