๐ Background
The detection of epileptic seizures is crucial for effective management and treatment, especially in elderly patients who often exhibit complex brain signal patterns. Traditional methods have struggled to accurately identify seizures due to the non-stationary dynamics of EEG signals in this demographic. This study aims to bridge that gap by leveraging advanced deep learning techniques to enhance diagnostic accuracy.

TFFBN-HDLF: a hybrid deep learning framework based on time-frequency functional brain networks for epileptic seizure detection.
Abstract
INTRODUCTION: The detection of epilepsy seizures in the elderly based on electroencephalogram (EEG) is the foundation of an intelligent clinical decision support system. However, due to the often slow background activity and complex non-stationary dynamic characteristics of the brain signals in elderly patients, existing methods often struggle to extract robust discriminative features across different individuals. To address this deficiency, this study proposes a hybrid deep learning framework named TFFBN-HDLF, aiming to enhance the reliability and diagnostic accuracy of artificial intelligence-assisted monitoring of epilepsy seizures in the elderly.
METHODS: Firstly, this paper presents a time-frequency functional brain network construction method (TFFBNC). By combining the Pearson correlation coefficient (PCC) and phase lag index (PLV), we construct a two-dimensional time-frequency fused functional brain network (TFPPNet). This method can comprehensively simulate the synchronous neural interactions in the time and frequency domains of the elderly brain, converting the complex raw EEG data into high-quality neurophysiological evidence, thereby providing a basis for clinical decision-making. Additionally, we have developed a hybrid deep learning architecture-SeizureTransNet, which combines convolutional neural networks (CNNs) with enhanced Transformer modules. This architecture can dynamically select and integrate multi-scale spatiotemporal features, ensuring accurate inference of the seizure state in the elderly while maintaining high adaptability to the different EEG pattern differences caused by aging.
RESULTS: Extensive evaluations on publicly available CHB-MIT and Siena datasets have confirmed the effectiveness of this framework. The accuracy of TFFBN-HDLF on the CHB-MIT dataset reached 98.09% (AUC of 99.45%), and on the Siena dataset, it was 92.49% (AUC of 95.64%).
DISCUSSION: These results indicate that the collaborative integration of attention-based time-frequency network fusion and feature learning significantly improves diagnostic performance, demonstrating its potential application in clinical care for epilepsy in the elderly.
