Epilepsy and Seizures: Overview

285
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

    Area of Science:

    • Neurology
    • Artificial Intelligence
    • Biomedical Engineering

    Background:

    • Current deep learning models for childhood epilepsy analysis using electroencephalogram (EEG) are task-specific, limiting their generalizability.
    • Foundation Models (FMs) have shown promise in medical data analysis, suggesting potential for complex neurological tasks.

    Purpose of the Study:

    • To develop a versatile FM with enhanced generalization capabilities for multi-task childhood epilepsy analysis.
    • To introduce the knowledge-guided foundation model for childhood epilepsy analysis (M4CEA).

    Main Methods:

    • Developed M4CEA, a knowledge-guided FM incorporating a mask strategy and temporal embeddings for multi-domain EEG signal representation.
    • Pre-trained M4CEA on over 1,000 hours of childhood EEG recordings.
    • Fine-tuned the model for performance on 8 distinct downstream tasks.

    Main Results:

    • M4CEA achieved promising performance on 8 diverse childhood epilepsy analysis tasks, including artifact detection, seizure classification, and HIE grading.
    • Demonstrated a 9.42% improvement in Balanced Accuracy on the HUH seizure detection task compared to the state-of-the-art LaBraM model.
    • The model effectively captures multi-domain representations from childhood EEG signals.

    Conclusions:

    • The M4CEA model offers a robust and generalizable solution for multi-task childhood epilepsy analysis.
    • Knowledge-guided FMs represent a significant advancement in analyzing complex neurological data like EEG.
    • The developed model and code are publicly available for further research and application.
