    This study introduces an advanced EEG source localization (ESL) method for pediatric epilepsy surgery, improving seizure outcome prediction. It effectively identifies the epileptogenic zone but requires caution for complex cases like Lennox-Gastaut syndrome.

    Area of Science:

    • Neuroscience
    • Medical Imaging
    • Epileptology

    Background:

    • Electroencephalography (EEG)-based source localization (ESL) aids epilepsy surgery by identifying the epileptogenic zone.
    • Existing methods lack cortical surface delineation and have limited data for pediatric and intracranial EEG cases.

    Purpose of the Study:

    • To propose and evaluate an Intracranial Disease-region Composite-interpretation (IDC) EEG-based source localization (ESL) scheme for pediatric epilepsy.
    • To enhance visualization and interpretation of intracranial EEG-based source localization (iESL) using 3D extended reality (XR) edge computing.

    Main Methods:

    • Development of the IDC-ESL scheme incorporating 3D XR edge computing.
    • Application of IDC-ESL to pediatric epilepsy patients undergoing surgery.

  • Analysis of seizure freedom correlation with resection of EEG features: interictal spike, high-frequency oscillation (HFO), and seizure onset zone (SOZ).

    • Main Results:

    • The IDC-ESL method effectively predicted surgical outcomes in focal epilepsy patients.
    • Complete resection of combined EEG features (interictal spike, HFO, SOZ) significantly correlated with seizure freedom.
    • IDC-ESL showed limitations in Lennox-Gastaut syndrome (LGS) due to deep lesions and multifocal abnormalities, particularly insular involvement.

    Conclusions:

    • The proposed IDC-ESL scheme is a valuable tool for epilepsy surgery, particularly for focal epilepsy.
    • Accurate localization of the epileptogenic zone is crucial for achieving seizure freedom.
    • Intraoperative electrocorticography (ECoG) is essential for precise insular resection in complex cases like LGS.
