Attention-Deficit/Hyperactivity Disorder01:30

Attention-Deficit/Hyperactivity Disorder

47
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Area of Science:

  • Neuroscience
  • Computational Psychiatry
  • Biomedical Engineering

Background:

  • Attention Deficit Hyperactivity Disorder (ADHD) is a common childhood disorder, yet accurate identification remains difficult.
  • Existing diagnostic methods may lack precision, necessitating advanced analytical approaches for ADHD detection.
  • Electroencephalography (EEG) data offers a promising avenue for objective ADHD assessment.

Purpose of the Study:

  • To develop and validate a novel feature selection method for ADHD detection using EEG data.
  • To investigate brain network connectivity differences between individuals with ADHD and controls.
  • To improve the accuracy and efficiency of ADHD classification through optimized feature selection.

Main Methods:

  • Constructed brain networks from EEG data using Transfer Entropy (TE) to analyze effective connectivity.
  • Implemented a dual-layer feature selection approach combining Recursive Feature Elimination (RFE) and Genetic Algorithm (GA).
  • Utilized a Support Vector Machine (SVM) classifier for ADHD diagnosis based on the selected EEG features.

Main Results:

  • Identified distinct brain connectivity patterns in ADHD patients compared to controls across alpha, beta, and gamma frequency bands.
  • The RFE-GA method significantly reduced the number of features while enhancing classification performance.
  • Achieved high classification accuracies: 91.3% (alpha), 94.1% (beta), and 90.7% (gamma).

Conclusions:

  • The proposed RFE-GA feature selection method is effective for ADHD detection using EEG data.
  • Optimized feature selection improves classification accuracy and reduces computational complexity.
  • This approach holds potential for more accurate and objective ADHD diagnosis.
