ANALYSIS OF FACIAL EXPRESSIONS IN PATIENTS WITH SCHZIOPHRENIA, IN COMPARISON WITH A HEALTHY CONTROL - CASE STUDY

Introduction: Deficits in area of communication, crucial for maintaining proper social bonds, may have a prominent adverse impact on quality of life in patients with schizophrenia. Social exclusion, lack of employment and deterioration of family life, may be consequences of aggravated social competencies, caused by inability to properly exhibit and interpret facial expressions. Although this phenomenon is known since first clinical descriptions of schizophrenia, lack of proper methodology limited our knowledge in this area. Aim of our study was to compare facial expressivity of the patient with schizophrenia, and the healthy individual. Methods: 47-years old patient suffering from schizophrenia, and 36-years old healthy individual were invited to participate in our study. They underwent the examination in Human Facial Modelling Lab in Polish-Japanese Institute of Information Technology in Bytom (Silesia, Katowice). Both participants were presented with two video materials, first one contained different facial expressions, which they had to imitate. Second one a part of comedy show, during which spontaneous reactions were recorded. Acquisition of facial expressions was conducted with marker-based technology of modelling. Obtained data was analyzed using Microsoft Excel. Results and conclusions: An overall facial expression intensity, expressed as an average value of distances traveled by markers during shifts from neutral position was higher in case of a healthy participant during both part of the study. The difference was especially visible in case of an upper half of the face. Utilization of marker-based methods in analysis of human facial expressions seem to be reliable and remarkably accurate

THE ROLE OF HORMONES AND INFLAMMATORY MARKERS IN COGNITIVE FUNCTIONING OF SCHIZOPHRENIC PATIENTS

Background: In the literature we can find evidence that immunological processes are involved the alterations of cognition in schizophrenic patients. Another factor, which may have an impact on cognitive domains in this clinical group are hormones. Objective: The objective of this review was to explore studies, in which the role of both immunological and endocrine factors on cognitive functions in schizophrenia are analyzed. Methods: The search of papers covering this topic in PubMed and Google Scholar was performed. Results: The studies focusing on this co-relation are not numerous. The role such hormones like cortisol, insulin and sex hormones may be important in the immunomodulatory processes influencing cognition in schizophrenia. Conclusions: More studies are necessary to confirm these possible co-relations

TELEPSYCHIATRY AND VIRTUAL REALITY IN THE TEATMENT OF PATIENTS WITH INTELLECTUAL AND DEVELOPMENTAL DISABILITIES

Background: Treatment and rehabilitation of people with intellectual and developmental disabilities is a multidisciplinary challenge, which require implementing new attitudes. The use of modern technology solutions like telepsychiatry or virtual reality may be a valuable addition to the traditional methods. Objective: The objective of this review was to explore the usability of new technological solutions in this special population of patients. Methods: The search in the PubMed was conducted using the following terms: (intellectual disability (Title/Abstract) OR developmental disability OR learning disorder (Title/Abstract)) AND virtual reality (Title/Abstract) OR telepsychiatry OR telemedicine OR e-mental health AND English (lang) AND (1995/01/01(PDAT): 2017/07/31(PDAT)). Results: Telepsychiatry may be a useful tool in situations, when the direct access to professional assistance is limited, in solving particular problems like e.g. managing challenging behavior, also to support patients’ parents and for diagnostic and educational purposes. Virtual reality can be a safe and effective method of improving different skills, developing physical fitness, and enriching the ways of spending the leisure time. Conclusions: Using modern technology is a relatively new and promising field in which new ideas may develop to support the already existing services for patients with intellectual and developmental disabilities
