Area of Science:
- Neurodevelopmental disorders
- Pediatric psychology
- Machine learning in healthcare
Background:
- Autistic spectrum disorder (ASD) is a neurodevelopmental condition impacting communication, social interaction, and behavior.
- Early identification of ASD traits in toddlers is vital for timely intervention and healthcare access.
- Existing diagnostic methods can be enhanced by identifying specific early behavioral indicators.
Purpose of the Study:
- To identify early behavioral features indicative of ASD in toddlers.
- To map identified features to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) neurodevelopmental criteria.
- To propose a machine learning-based data process for ASD detection in early childhood.
Main Methods:
- Investigated various ASD behavioral features in toddlers.
- Employed feature selection techniques to identify relevant behavioral indicators.
- Developed classification models, including Bayesian Network (Bayes Net) and Logistic Regression (LR), using selected features.
- Mapped identified features to DSM-5 neurodevelopmental areas.
Main Results:
- Cognitive features related to communication, social interactions, and repetitive behaviors were most relevant for ASD screening in toddlers.
- Machine learning models (Bayes Net, LR) demonstrated consistent predictive accuracy using ASD behavioral data subsets.
- The study successfully identified key behavioral markers for early ASD detection.
Conclusions:
- Machine learning techniques are suitable for predicting Autistic Spectrum Disorder (ASD) in toddlers.
- Early identification of specific behavioral features can significantly aid in the diagnosis and management of ASD.
- The proposed data process offers a promising approach for early ASD detection, facilitating prompt clinical referrals and healthcare access.
