Epileptic Seizure Detection and Prediction from EEG Data: A Machine Learning Approach with Clinical Validation
In recent years, machine learning has become an increasingly powerful tool for supporting seizure detection and monitoring in epilepsy care. Traditional approaches focus on identifying seizures only after they begin, which limits the opportunity for early intervention and proactive treatment. In this study, we propose a novel approach that integrates both real-time seizure detection and prediction, aiming to capture subtle temporal patterns in EEG data that may indicate an upcoming seizure. Our approach was evaluated using the CHB-MIT Scalp EEG Database, which includes 969 hours of recordings and 173 seizures collected from 23 pediatric and young adult patients with drug-resistant epilepsy. To support seizure detection, we implemented a range of supervised machine learning algorithms, including K-Nearest Neighbors, Logistic Regression, Random Forest, and Support Vector Machine. The Logistic Regression achieved 90.9% detection accuracy with 89.6% recall, demonstrating balanced performance suitable for clinical screening. Random Forest and Support Vector Machine models achieved higher accuracy (94.0%) but with 0% recall, failing to detect any seizures, illustrating that accuracy alone is insufficient for evaluating medical ML models with class imbalance. For seizure prediction, we employed Long Short-Term Memory (LSTM) networks, which use deep learning to model temporal dependencies in EEG data. The LSTM model achieved 89.26% prediction accuracy. These results highlight the potential of developing accessible, real-time monitoring tools that not only detect seizures as traditionally done, but also predict them before they occur. This ability to predict seizures marks a significant shift from reactive seizure management to a more proactive approach, allowing patients to anticipate seizures and take precautionary measures to reduce the risk of injury or other complications.

Advanced Seizure Detection Models
Our study thoroughly evaluated various supervised machine learning algorithms for real-time seizure detection. While some models like Random Forest and SVM showed high overall accuracy, they often failed to detect actual seizure events due to severe class imbalance. Logistic Regression emerged as a balanced performer, achieving 90.9% detection accuracy with a crucial 89.6% recall, making it suitable for clinical screening. The critical role of SMOTE (Synthetic Minority Oversampling Technique) in balancing the dataset was highlighted, transforming models from 0% recall to clinically viable performance by generating synthetic seizure samples.
Pioneering Seizure Prediction with LSTM
A significant advancement of this research is the implementation of Long Short-Term Memory (LSTM) networks for seizure prediction. Unlike traditional methods, LSTM models temporal dependencies in EEG data, learning complex patterns that precede a seizure. This deep learning approach achieved an impressive 89.26% prediction accuracy, demonstrating its potential to shift epilepsy management from reactive to proactive. This capability allows for early warnings, enabling patients and caregivers to take preventative measures, significantly reducing risks and improving quality of life.
Real-World Clinical Impact & Future Directions
The patient-independent validation approach used ensures that our models generalize to unseen individuals, a critical factor for real-world medical applications. The ability to predict seizures is a fundamental shift, moving beyond just detection to offer preventative interventions. This technology can be integrated into wearable EEG devices and smart monitoring systems, providing real-time forecasting. Such innovations empower patients to identify personal triggers, make informed lifestyle modifications, and drastically reduce physical injuries and psychological trauma associated with unpredictable seizures. Future work includes expanding to more diverse patient datasets and exploring advanced deep learning algorithms.
Robust Data & Validation Process
Our methodology utilized the publicly available CHB-MIT Scalp EEG Database, comprising 969 hours of recordings and 173 seizures from 23 pediatric and young adult patients. EEG data was processed into 2-second epochs, followed by noise reduction techniques like ICA and SSP. To address the severe class imbalance, SMOTE oversampling was exclusively applied to the training data. A rigorous patient-independent 5-fold cross-validation was employed, ensuring that models were evaluated on entirely unseen patient data, thus preventing data leakage and enhancing generalizability to new EEG data.

Clinical Application & Monitoring
Transforming Epilepsy Care: From Reactive to Proactive
The traditional paradigm of epilepsy care often leaves patients and caregivers in a constant state of anxiety, reacting to seizures only after they have begun. This study's breakthrough in seizure prediction, achieving 89.26% accuracy with LSTM models, offers a profound shift. By enabling patients to anticipate seizures, it facilitates immediate precautionary measures, such as seeking assistance or moving to a safe environment, thereby significantly reducing the risk of injury and complications. This proactive management capability also empowers individuals to better understand their personal triggers and make crucial lifestyle adjustments, fostering greater independence and an improved quality of life. Implementing this AI-driven predictive technology into accessible, real-time monitoring tools could revolutionize epilepsy care globally, addressing current limitations in access to specialized EEG tests and offering a scalable solution for continuous patient safety.
