Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Background:

Reliable seizure prediction is crucial for patient safety but often requires complex multichannel EEG systems.
Existing high-performing seizure prediction models are limited in wearable and low-power applications due to high computational demands.

Purpose of the Study:

To develop and evaluate an ultralight deep learning model for seizure prediction using only single-channel EEG.
To assess the clinical applicability of the model within a seizure prediction horizon (SPH) of 2 minutes and a seizure occurrence period (SOP) of 30 minutes.

Main Methods:

A lightweight, MobileNet-derived deep learning architecture (37,985 parameters) was designed to process STFT spectrograms from single-channel EEG.
The model was validated using patient-specific leave-one-out cross-validation on the SNUH and CHB-MIT datasets.
Performance was evaluated using segment-based accuracy, false positive rate (FPR), and event-based sensitivity under defined SPH-SOP constraints.

Main Results:

The model demonstrated strong and consistent performance on both SNUH and CHB-MIT datasets.
In the SNUH cohort: 85.97% accuracy, 0.130 FPR, 94.93% sensitivity, predicting 95.08% of seizures within the SOP.
In the CHB-MIT dataset: 90.72% accuracy, 0.092 FPR, 97.92% sensitivity.

Conclusions:

Single-channel EEG can support reliable seizure prediction within clinically actionable early-warning windows.
The proposed lightweight model achieves multichannel-comparable performance with significantly reduced computational requirements.
This model shows strong potential for real-time deployment in wearable and patient-centered epilepsy management systems.
