Deep-learning-based intelligent neonatal seizure identification using spatial and spectral GNN optimized with the Aquila algorithm

Abstract

<abstract> <p>Diagnosing and treating newborn seizures accurately and promptly is crucial for providing the best possible care for these patients. For the purpose of intelligently identifying newborn seizures, this work introduced a unique method that uses spectral and spatial graph neural networks (SSGNNs) optimized with the Aquila algorithm. Using electroencephalogram (EEG) recordings, the suggested methodology takes advantage of the complex spatial and spectral characteristics of infant brain activity. Spatial and spectral GNNs were used to extract significant spatiotemporal patterns suggestive of seizure episodes by organizing the brain activity data as a graph, with nodes representing various brain regions and edges signifying functional relationships. By combining spectral and spatial data, the depiction of newborn brain dynamics was improved and made it possible to distinguish between seizure and non-seizure phases with greater accuracy. Moreover, the introduction of the Aquila algorithm improved the GNNs' performance in seizure identification tasks by streamlining the training process. A large dataset of EEG recordings from newborns with and without seizures was used to assess the effectiveness of the suggested method. Higher accuracy, sensitivity, and specificity in seizure detection were achieved in the experimental results, which showed greater performance when compared to conventional methods. This work offered an automated, data-driven method for identifying newborn seizures, which is a major development in the treatment of newborns. By combining spectral and spatial GNNs and optimizing the results using the Aquila method, it is possible to enhance seizure detection accuracy and potentially prevent neurological consequences in affected children by intervening early. This method has the potential to completely change the way neonatal care is provided by giving medical professionals a strong tool for accurate and prompt seizure monitoring in neonatal intensive care units (NICU).</p> </abstract>
