   <abstract xml:lang="ru">
    <p>С использованием методик «10 слов» и «таблицы Шульте» проанализированы некоторые параметры когнитивного статуса у курящих (n=32) и некурящих (n=40) студентов медицинского института КГУ им. К. Э. Циолковского. Установлены статистически значимые изменения параметров когнитивного статуса у курящих студентов: на фоне сопоставимой по значениям с некурящими добровольцами достаточно быстрой врабатываемости в задание, регистрируется истощаемость внимания и снижение мнестических функций у курящих. Это подтверждается снижением объёма долговременной памяти, концентрации внимания, эффективности работы и психической устойчивости. Негативное влияние курения на когнитивный статус обучающихся медицинского института необходимо рассматривать с позиции формирования приоритетов здорового образа жизни, поскольку будущие врачи отчасти несут личную ответственность за позитивное решение проблемы курения в обществе.</p>

   <trans-abstract xml:lang="en">
    <p>A controlled, open, randomized study was conducted to assess the characteristics of the cognitive status of smoking and nonsmoking students of the Medical Institute of Tsiolkovsky Kaluga State University (Kaluga, Russia). Students were randomized into 2 groups: the first group of volunteers (n = 40) consisted of nonsmokers, the second group (n = 32) – smokers. To assess the cognitive status, the «10 words» and «Schulte tables» methods were used.&#13;
The results of the study showed that the first reproduction of ten monosyllabic words when tested using the «10 words» method does not have statistically significant differences between the groups and allows us to state that the volume of short-term memory in smoking and non-smoking volunteers is practically identical. At the same time, further reproduction (second to fifth) indicates a reliable decrease in the level of memorization in volunteers of the second group compared to the first, amounting to 10–20 % (p&lt;0.05). Evaluation of the volume of long-term memory (sixth reproduction) showed a statistically significant decrease in the parameter (by 34 %, p&lt;0.05) in smoking students relative to non-smoking students.&#13;
The assessment of the attention volume, its stability, and mental tempo using Schulte tables showed that in both the first and second groups of students, the task completion time was within the normal range: both non-smokers and smokers had sufficient stability of voluntary attention and mental activity tempo. However, the time spent working with the fifth table by smokers was 43 % higher than the same indicator by non-smokers (p&lt;0.05), which affected the calculated indicators: the work efficiency in the second group was 24 % lower than the same parameter in the first, and mental stability was 18 % lower (p&lt;0.05).&#13;
The study allowed us to establish statistically significant changes in the parameters of the cognitive status of smoking students: with a fairly quick adaptation to the task, comparable in values with non-smoking volunteers, there is sufficient exhaustion of attention against the background of a decrease in mnemonic functions in smokers, which is confirmed by a decrease in the volume of long-term memory, concentration, work efficiency and mental stability.</p>
