Neurology
Artificial Intelligence
Biomedical Engineering

Background:

Routine electroencephalogram (EEG) has limited sensitivity for epilepsy diagnosis.
Interictal epileptiform discharges (IEDs) can be misinterpreted, affecting diagnostic accuracy.

Purpose of the Study:

To develop and validate a deep learning model for epilepsy identification from raw EEG data.
To compare the model's performance against traditional IED interpretation and existing machine learning methods.

Main Methods:

Retrospective cohort study including 948 EEGs from 846 patients.
Development of seven deep learning models, including Vision Transformers and Convolutional Neural Networks.
Temporal validation cohort used to assess diagnostic accuracy.

Main Results:

The Vision Transformer model, DeepEpilepsy, achieved an AUC of 0.76, outperforming IED interpretation (AUC 0.69).
Combining DeepEpilepsy with IEDs further improved performance to an AUC of 0.83.
DeepEpilepsy identified epilepsy independently of IEDs, suggesting detection of novel EEG patterns.

Conclusions:

Deep learning models like DeepEpilepsy can enhance epilepsy diagnosis from routine EEG.
The model's ability to detect epilepsy independently of IEDs highlights potential for discovering new diagnostic biomarkers.
Further research is warranted to elucidate the detected EEG patterns and assess clinical utility.
