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.

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...

Area of Science:

Medical imaging analysis
Developmental neuroscience
Machine learning in healthcare

Background:

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder impacting communication and behavior.
Early diagnosis and intervention are crucial for improving outcomes for children with ASD and their families.
Identifying reliable biomarkers for ASD can significantly aid in early detection.

Purpose of the Study:

To investigate the effectiveness of static facial features as biomarkers for distinguishing children with ASD from neurotypical children.
To evaluate the performance of various pre-trained Convolutional Neural Network (CNN) models in identifying autism from facial images.
To assess the potential of deep learning models for accurate autism diagnosis in pediatric populations.

Main Methods:

Utilized five pre-trained CNN models (MobileNet, Xception, EfficientNetB0, EfficientNetB1, EfficientNetB2) as feature extractors.
Employed a Deep Neural Network (DNN) model as a binary classifier for autism detection.
Trained and validated models on a public dataset of facial images from children diagnosed with ASD and control groups.

Main Results:

The Xception model demonstrated superior performance, achieving an Area Under the Curve (AUC) of 96.63%, 88.46% sensitivity, and 88% Negative Predictive Value (NPV).
EfficientNetB0 provided a consistent prediction score of 59% for both autistic and non-autistic groups with a 95% confidence level.
The study highlights the potential of specific CNN architectures in identifying subtle facial markers associated with ASD.

Conclusions:

Static facial features extracted using CNNs show promise as a non-invasive biomarker for autism spectrum disorder.
The Xception model is a highly effective tool for the accurate identification of autism in children based on facial imagery.
Further research and validation are warranted to integrate these AI-driven approaches into clinical diagnostic pathways for ASD.
