Establishing reliable neurophysiological markers as objective assessment tools can increase diagnostic accuracy and improve outcomes.</p> <p><bold>AIM: </bold>To identify neurophysiological correlates of impaired facial expression perception in patients with schizophrenia and schizoaffective disorder, and to develop a diagnostic model based on these markers.</p> <p><bold>METHODS:</bold> The study included 86 participants: 26 with schizophrenia, 26 with schizoaffective disorder, and 34 healthy volunteers. The study recorded electrical brain activity in response to stimuli with faces showing happy, fearful, and neutral expressions using a 128-channel electroencephalographic system. The P100, N170, P200, and P300 components were analyzed. Logistic regression and ROC analysis were used to develop a diagnostic model.</p> <p><bold>RESULTS:</bold> We developed a diagnostic model that differentiates patients with schizophrenia and schizoaffective disorder from healthy participants. The model achieved 73.3% sensitivity and 80% specificity.</p> <p><bold>CONCLUSION: </bold>The findings demonstrate the diagnostic value of evoked potentials and support their application as a supplementary objective diagnostic tool.</p></abstract><trans-abstract xml:lang="ru"><p><bold>ВВЕДЕНИЕ: </bold>Шизофрения и шизоаффективное расстройство — заболевания, значительно влияющие на когнитивное и эмоциональное функционирование пациентов.
