Малоизученным остается вопрос о характере связи зрительных нарушений и более высокоуровневых когнитивных функций при шизофрении.</p><p>Цель исследования — изучение различий в обработке зрительной информации между лицами с параноидной шизофренией и здоровыми людьми, а также анализ взаимосвязи характеристик зрительной системы с клиническими и когнитивными факторами.</p></sec><sec><title>Пациенты и методы</title><p>Пациенты и методы: в кросс-секционное исследование были включены 33 пациента с параноидной формой шизофрении и 19 здоровых испытуемых. Когнитивные нарушения оценивали с помощью батареи тестов краткой оценки когнитивных функций у пациентов с шизофренией (Brief Assessment of Cognition in Schizophrenia, BACS), а тяжесть психического состояния — с использованием шкалы позитивных и негативных симптомов (Positive and Negative Symptom Scale, PANSS). Характеристики контрастной чувствительности измеряли с помощью компьютерной визоконтрастометрии.</p></sec><sec><title>Результаты</title><p>Результаты: установлено, что зрительная система больных шизофренией характеризуется повышенной контрастной чувствительностью в диапазоне высоких и средних пространственных частот, но сниженной чувствительностью в низкочастотном диапазоне. Снижение контрастной чувствительности в области низких пространственных частот было связано с лучшим когнитивным функционированием и менее выраженными продуктивными симптомами. Контрастная чувствительность в диапазоне средних пространственных частот (СЧ) на уровне тенденций коррелировала с тестами «Порядок чисел», оценивающим рабочую память, и «Речевая беглость», отражающим скорость обработки информации.</p></sec><sec><title>Выводы</title><p>Выводы: полученные данные расширяют информацию о характере связей между контрастной чувствительностью и когнитивными функциями. Результаты исследования обеспечат основу для дальнейших разработок более эффективных немедикаментозных методов улучшения когнитивного функционирования.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background: increasing interest in visual disturbances in schizophrenia is connected with the fact that they are a potential biomarker for objectiﬁcation of a mental condition. The nature of the relationship between visual disturbances and higher-level cognitive functions in schizophrenia remains understudied.</p><p>The aim of the study was to investigate differences in visual information processing between individuals with paranoid schizophrenia and healthy individuals, and to analyze the relationship between visual system characteristics with clinical and cognitive factors.</p></sec><sec><title>Patients and methods</title><p>Patients and methods: thirty-three patients with the paranoid form of schizophrenia and 19 healthy subjects were included in the cross-sectional study. Cognitive impairment was assessed using a battery of BACS tests, and the severity of the mental state was assessed using the PANSS scale. Contrast sensitivity characteristics were measured by computer visocontrastometry.</p></sec><sec><title>Results</title><p>Results: the study found that the visual system of persons with schizophrenia is characterized by hypersensitivity in the high and midrange, but decreased sensitivity in the low-frequency range. Decreased sensitivity in the low-frequency range was associated with better cognitive functioning and less pronounced productive symptoms. Medium frequencies at the trend level correlated with the digit sequencing tests, assessing working memory, and verbal ﬂuency, reﬂecting speed of information processing.</p></sec><sec><title>Conclusions</title><p>Conclusions: our ﬁndings expand information on the character of the relationship between contrast sensitivity and cognitive function. The results of study will provide the basis for further research on the development of more effective non-medicinal methods to improve cognitive functioning.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>шизофрения</kwd><kwd>когнитивные функции</kwd><kwd>контрастная чувствительность</kwd><kwd>зрение</kwd><kwd>BACS</kwd><kwd>PANSS</kwd></kwd-group><kwd-group xml:lang="en"><kwd>schizophrenia</kwd><kwd>cognitive functions</kwd><kwd>contrast sensitivity</kwd><kwd>vision</kwd><kwd>BACS (Brief Assessment of Cognition in Schizophrenia)</kwd><kwd>PANSS (Positive and Negative Syndrome Scale)</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке гранта РНФ (проект № 22-18-00074) «Психологические механизмы рассогласования восприятия и действия при решении задач в условиях зрительных иллюзий».</funding-statement><funding-statement xml:lang="en">This work was supported by a grant from the Russian Science Foundation (project # 22-18-00074) “Psychological mechanisms of perception and action mismatch when solving tasks under visual illusions”.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Silverstein SM, Keane BP, Wang Y, Mikkilineni D, Paterno D, Papathomas TV, Feigenson K.
