Все больше исследований в последние годы посвящено изучению геропротективных механизмов, влиянию различных состояний и заболеваний на старение в целом. Особое значение имеют определение возрастных инволютивных процессов в организме человека, решение вопроса о том, являются ли они частью нормального старения или патологией, которую необходимо корректировать в пожилом возрасте. Важным возраст-ассоциированным процессом является изменение активности эндокринной системы, одним из примеров которого являются нарушения в работе щитовидной железы. Высокая распространенность гипотиреоза в пожилом возрасте объясняет актуальность данной темы и наш интерес к ее изучению. Нашей задачей было оценить влияние снижения функции щитовидной железы на течение заболеваний у пациентов пожилого возраста. Нами был проведен обзор литературы за последние 10 лет, посвященный терапии гипотиреоза у гериатрических пациентов, и выявлены наиболее актуальные проблемы, связанные с компенсацией данной патологии у пожилых пациентов. Были изучены данные о взаимосвязи гипотиреоза и основных гериатрических синдромов, особое внимание было уделено связи с когнитивными нарушениями и нарушениями эмоциональной сферы.</p></abstract><trans-abstract xml:lang="en"><p>Searching for aging key points is one of the main problems in geriatrics. More and more research in recent years has been devoted to the study of geroprotective mechanisms, the impact of various conditions and diseases on aging in general. Of particular importance is the determination of age-related involutive processes in the human body, whether they are part of normal aging or a condition that needs to be corrected to improve the functioning of organs and systems. An important mechanism of aging starts is a change in hormonal activity of endocrine glands, in particular in hormonal activity of thyroid. Frequency of hypothyroidism in advanced age explains relevance of the chosen topic. The aim of the review was to find out the role hypothyroidism in aging. The main task was to define, whether thyroid hormones decrease in older age was a protective factor or pathological process. A review of the literature over the past 10 years on subclinical treatment was carried out and we identified the most pressing issues associated with hypothyroidism and aging. We studied data on the relationship between hypothyroidism and major geriatric syndromes, with special attention paid to cognitive diseases and emotional disorders.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гипотиреоз</kwd><kwd>субклинический гипотиреоз</kwd><kwd>долголетие</kwd><kwd>старение</kwd><kwd>гормональная терапия</kwd><kwd>тиреотропный гормон</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypothyroidism</kwd><kwd>subclinical hypothyroidism</kwd><kwd>longevity</kwd><kwd>aging</kwd><kwd>hormone therapy</kwd><kwd>thyroid-stimulating hormone</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по инициативе авторов без привлечения финансирования</funding-statement></funding-group></article-meta></front><back><ref-list><ref id="cit1"><mixed-citation publication-type="commun" publication-format="web"><article-title>Endokrinologiya.
