Area of Science:

Neuroscience
Biomedical Engineering
Artificial Intelligence

Background:

Electroencephalogram (EEG) is crucial for monitoring brain activity and detecting seizures.
EEG signal asymmetry can indicate epileptic activity, differentiating normal, interictal, and ictal states.
Accurate seizure detection is vital for epilepsy diagnosis and management.

Purpose of the Study:

To develop an improved, automated EEG-based seizure detection system.
To leverage deep neural networks (DNNs) and the Binary Dragonfly Algorithm (BDFA) for enhanced seizure detection.
To analyze EEG signal symmetry and asymmetry for improved diagnostic accuracy.

Main Methods:

Utilized Stationary Wavelet Transform to decompose EEG signals.
Extracted nine statistical and Hjorth parameters as features.
Employed a Deep Neural Network (DNN) for signal analysis.
Applied the Binary Dragonfly Algorithm (BDFA) for feature selection and optimization.

Main Results:

Achieved 100% accuracy, sensitivity, specificity, and F1 score in differentiating normal, interictal, and ictal EEG signals.
Reduced features by 87% using BDFA, selecting a 13% subset.
Demonstrated superior performance compared to existing seizure detection approaches.

Conclusions:

The proposed DNN and BDFA model effectively detects seizures using EEG signal asymmetry.
Feature selection via BDFA significantly improves DNN training speed and performance.
This automated system offers a promising tool for epilepsy diagnosis and management.
