Schizophrenia is a severe mental disorder characterized by distorted thinking, perceptions, emotions, and behavior, which can significantly impair an individual’s ability to function in daily life. Early and effective diagnosis is crucial, as it enables timely intervention, which can improve outcomes and reduce the burden on patients and healthcare systems. Existing research in schizophrenia diagnosis often faces challenges related to the use of single-channel frequency EEG signals, which can overlook critical information provided by multi-channel data and limit the model’s ability to accurately capture the spatial and temporal dynamics of brain activity. In our proposed work, we introduce a novel model named EEG-SymNet: Spatial-Temporal Channel Recalibration Network for Schizophrenia Diagnosis using EEG signals, designed to enhance schizophrenia diagnosis through the utilization of multi-channel frequency EEG signals. Our approach begins with noise correction and power spectrum analysis to improve the quality of the EEG signals, ensuring a more reliable foundation for subsequent analysis. The pre-processed signals are then fed into our model, which consists of four main modules. First, Hierarchical Spatial Temporal Graph Neural Network (HSTG-Net) captures spatial features across channels, allowing for a comprehensive understanding of the EEG data. Next, the Multi-Channel Frequency Recalibration Module (CRFM) refines the model’s ability to interpret complex inter-channel relationships, enhancing inter-channel communication. Following this, Symmetric Transformer (Sym-T) enhances the learned temporal relations in the features, effectively capturing time-dependent patterns relevant to schizophrenia. Finally, a classifier layer is employed to provide accurate classification of the signals into schizophrenia and non-schizophrenia categories. The proposed STCR-Net model, which achieved an accuracy of 92.34 %, sensitivity of 91.78 %, specificity of 92.67 %, F1-Score of 0.92, and AUC of 0.95, demonstrating significant diagnostic improvements. Our proposed model addresses existing limitations and offers a robust framework for advancing the diagnosis of schizophrenia.
