The recognition of facial signals has a crucial role in social interaction. It is well known that people suffering from paranoid schizophrenia have problems in the social domain, predominantly related to misinterpreting the intentions, emotions, and actions of others. The aim of this study was to examine whether there are differences in facial emotion recognition between people with paranoid schizophrenia and healthy controls. In addition, we examined the correlation between facial emotion recognition and the expression of persecutory ideation in people suffering from paranoid schizophrenia. The study involved 60 participants, 30 of whom suffered from paranoid schizophrenia and 30 healthy controls, equalized by gender, age, and education. The following instruments were used: Japanese and Caucasian Facial Expressions of Emotion and Neutral Faces and the Persecutory Ideation Questionnaire. Compared with the controls, people suffering from paranoid schizophrenia were significantly less accurate in recognizing the following emotions: surprise, contempt, sadness, disgust, and emotionally neutral faces. Since the attribution of emotions to emotionally neutral faces is an important finding that could be linked with the social (dis)functionality of people suffering from paranoid schizophrenia, we analyzed and compared the wrong answers given by the two groups and found some differences between them. The results show that persecutory ideation has a statistically significant negative correlation with the successful recognition of emotionally neutral faces. All of the findings lead to the conclusion that paranoid schizophrenia, and within it the existence of persecutory ideation, leads to problems in recognizing the basic facial signals that form the foundation of everyday social interaction.

Schizophrenia is a chronic psychiatric disorder marked by severe disturbances in thought, perception, and behavior. Long-acting injectable (LAI) antipsychotics, such as paliperidone, are widely used to promote sustained remission and ensure medication adherence, especially in patients prone to relapse. However, the COVID-19 pandemic has introduced unique challenges, with studies indicating that infections like COVID-19 may exacerbate psychiatric symptoms through neuroinflammatory pathways.
