В пожилом и старческом возрасте ДУКС может быть предиктором развития более значительных когнитивных нарушений вплоть до развития деменции.</p><p>Целью исследования был анализ нейропсихологических характеристик пациентов с ДУКС в зависимости от возраста.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Проанализированы результаты обследования 547 пациентов (159 мужчин и 388 женщин) в возрастных группах 45–59 лет, 60–74 лет и 75–89 лет в сравнении с показателями  104 здоровых испытуемых с теми же возрастными характеристиками,  не предъявлявших жалобы на ухудшение когнитивных функций. Исследование включало клиническое обследование и применение набора шкал и опросников, оценивающих когнитивные функции.</p></sec><sec><title>Результаты</title><p>Результаты.  Выявлены достоверные  различия пациентов с ДУКС и здоровых испытуемых среднего и пожилого возраста по большинству нейропсихологических тестов. Пациенты старше 75 лет отличались от здоровых только по тесту рисования часов и непосредственному  воспроизведению  12 слов, наиболее значимыми различиями показателей нейропсихологических  тестов в разных возрастных группах здоровых испытуемых было ухудшение управляющих функций и показателя теста непосредственного воспроизведения 12 слов. У пациентов с ДУКС имелось ухудшение с возрастом показателей внимания, управляющих и речевых функций, конструктивного праксиса, тогда как в тестах на память значимой динамики не обнаружено. </p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с ДУКС происходит ухудшение большего спектра когнитивных функций чем у здоровых. При этом ухудшение памяти имеет устойчивый характер, существенно не зависящий от возраста.</p></sec></abstract><trans-abstract xml:lang="en"><p>Pre-Mild Cognitive Impairment (PreMCI) is characterized by patients’ complaints of  memory impairment and/or other cognitive functions. In elderly and senile age, PreMCI can be a predictor of the development of more significant cognitive defects up to the development of dementia.</p><p>The study was aimed at the analysis of the neuropsychological characteristics of patients with PreMCI in dependence on their age.</p><sec><title>Materials and methods</title><p>Materials and methods. The results of the examination of 547 patients (159 men and 388 women) in the age groups of 45–59 years old, 60–74 years old and 75–89 years old were analyzed in comparison to 104 healthy   subjects with the same age characteristics who did not complain of cognitive functions’ impairment. The study included clinical research and the use of  scales and questionnaires set evaluating cognitive functions.</p></sec><sec><title>Results</title><p>Results. Significant differences were detected between patients with PreMCI and healthy   subjects of middle and old age in most neuropsychological tests. Patients over 75 years old differed from healthy ones only in the clock drawing test and immediate reproduction of 12 words test.  Most significant difference in neuropsychological tests in different age groups of healthy    subjects was impairment in executive functions and the index of the 12-word immediate reproduction test. Patients with PreMCI had a deterioration of divided-attention measure indicators, executive and language functions, and constructional praxis, while in memory tests  no significant dynamics was detected. </p></sec><sec><title>Conclusion</title><p>Conclusion. A broader spectrum of cognitive functions’ defects is detected in patients with PreMCI compared to healthy ones. At the same time, memory impairment is a fixed condition, and is not essentially dependent on age.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>когнитивные нарушения</kwd><kwd>возраст</kwd><kwd>доумеренное когнитивное снижение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cognitive impairment</kwd><kwd>age</kwd><kwd>pre-mild cognitive decline</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа  выполнена  при  поддержке компании «Мерц-Фарма».</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The research was carried out with the support of Mertz pharma.</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">Локшина А.
