This study evaluates the effectiveness of combining electroencephalogram (EEG) data with machine learning techniques to enhance ADHD diagnostic accuracy.\u003Cbr>Methods: A total of 168 participants, comprising 107 ADHD and 61 neurotypical (NT) individuals, were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia Present and Lifetime Version Korean Version (K-SADS-PL-K) . EEG data from 19 channels were analyzed across five frequency bands: delta (1–4 hz), theta (4–8 hz), alpha (8–12 hz), beta (12–30 hz), and gamma (30–51 hz) . The Extreme Gradient Boosting (XGBoost) classifier was employed for classification, and Leave-One-Subject-Out (LOSO) cross-validation was used to ensure model robustness.\u003Cbr>Results: Data augmentation through 30-second segmentations generated 2434 EEG segments for ADHD and 1060 for NT. The XGBoost model achieved a test accuracy of 90.81% and an F1-score of 0.9347. Feature importance analysis using SHAP (SHapley Additive exPlanations) values identified middle beta frequency features, particularly from the O1 electrode site, as significant contributors to classification.\u003Cbr>Conclusion: EEG-based machine learning models, such as the XGBoost classifier, show potential as non-invasive tools for ADHD diagnosis, offering high accuracy and interpretability. The novelty of this approach lies in combining SHAP analysis with data augmentation techniques and LOSO cross-validation, ensuring both explainability and robust generalizability. Future research with larger datasets and diverse populations is recommended to validate findings and explore clinical applications.\u003Cbr>Keywords: attention deficit hyperactivity disorder, ADHD, machine learning, quantitative electroencephalography, diagnosis |\n| --- |\n| Introduction\u003Cbr>Attention Deficit Hyperactivity Disorder (ADHD) is a common neurodevelopmental disorder characterized by inattention, hyperactivity, and impulsivity, affecting both children and adults globally.1 The prevalence of ADHD in children is estimated to be approximately 5%, while around 4.4% of adults are reported to exhibit persistent ADHD symptoms.2 As of 2020, when adjusted for global population characteristics, the prevalence of ADHD starting in childhood and persisting into adulthood was estimated at 2.58%, translating to approximately 139.84 million individuals. Additionally, the prevalence of adult ADHD symptoms unrelated to childhood onset was reported at 6.76%, corresponding to about 366.33 million individuals worldwide. These figures highlight the significant public health burden posed by ADHD on a global scale.3\u003Cbr>In addition to core symptoms such as inattention,
