| Summary: | Schizophrenia is a brain disorder that disrupts behavioral and cognitive manifestations such as thinking, perception and speech. Early diagnosis of schizophrenia plays an important role in treating and limiting the effects of the disease. An automated diagnosis system for schizophrenia detection through a deep learning model is suggested in this research. For this purpose, EEG signals were captured from 36 patients with schizophrenia and 36 healthy controls at resting state. After data preprocessing to reduce noise and artifacts from EEGs, an 11-layer deep learning model consisting of convolution and LSTM layers with LeakyReLU activation function and different kernel sizes was implemented to automatically extract and classify features. The proposed deep learning network produced impressive classification accuracies of 99.33% and 98.49% for 10-fold cross-validation and random splitting methods, respectively. The proposed framework successfully classified the schizophrenia patients with healthy controls with an overall accuracy of 99.33%, sensitivity of 99.26%, specificity of 99.42% and PPV of 99.50%. This robust end-to-end system is expected to be useful as a diagnostic tool for clinicians and provide valuable support in the assessment of schizophrenia due to its automated nature for EEG processing. |
