If SARS-CoV-2 has a specific route of entry into the brain, it may leave imprints in the form of specific changes in brain morphology. Older individuals are most vulnerable to the neuropsychiatric COVID-19 complications. This study aims to compare regional brain volumes in older adults individuals with and without COVID-19 history (COVID+ and COVID-, respectively).</p> <p>METHODS: Individuals over 65 years old who applied for treatment to the Memory Clinic (Mental-Health Clinic No. 1 named after N.A. Alexeev, Moscow, Russia) were assessed between October 2020 and April 2021. Their COVID-19 history was determined by the self-report and COVID-19 certificate. Individuals with severe neuropsychiatric or acute or severe chronic somatic or infectious disease and those taking medications potentially affecting cognitive functioning were excluded. All participants underwent MRI examinations followed by image segmentation and morphometric quantitative analysis. Regional brain volumes were compared in COVID+ and COVID- people.</p> <p>RESULTS: 207 participants were included in the study. The COVID+ group consisted of 24 participants. The comparison between groups revealed statistically significant differences in left amygdala area (median 1199.3 mm<sup>3</sup> in COVID+ vs. 1263.7 mm<sup>3</sup> in COVID-) and right postcentral gyrus volumes (median 8055.5 mm<sup>3</sup> in COVID+ vs. 8434.0 mm<sup>3</sup> in COVID-). Then case-control analysis was performed in individuals matched for gender, age and common somatic causes of structural brain changes (hypertension and/or diabetes mellitus type 2) for 22 subjects in each group. Statistically significant differences in regional brain volumes between groups were absent.</p> <p>CONCLUSION: We did not find strong evidence for any regional brain volumes changes in people older than 65 years with a history of COVID-19 in comparison to those without history of COVID-19. Though, given study limitations, these results cannot be generalized to other people who recovered from COVID-19.</p></abstract><trans-abstract xml:lang="ru"><p>ВВЕДЕНИЕ: В недавних исследованиях было показано, что SARS-CoV-2 может иметь нейропсихиатрические последствия и обладает способностью проникать через гемато-энцефалический барьер. Если коронавирус имеет специфический путь проникновения в головной мозг, то это может оставлять отпечатки в виде характерных изменений морфологии мозга. Лица старшей возрастной группы являются наиболее уязвимой популяцией в отношении последствий COVID-19. Данное исследование нацелено на сравнение морфологии головного мозга у лиц пожилого возраста, перенесших (COVID+) и не перенесших (COVID-) новую коронавирусную инфекцию.</p> <p>МЕТОДЫ: В период с октября 2020 по апрель 2021 года отбирались лица старше 65 лет, обратившиеся в Клинику памяти (Москва), у которых путем анкетирования определялся статус перенесенного COVID-19. Не включались лица, имеющие тяжелые нейропсихиатрические и соматические заболевания и принимающие лекарственную терапию, потенциально сказывающиеся на когнитивном функционировании. Всем участникам проведено МРТ-обследование с последующей сегментацией изображений и количественным анализом морфометрических данных. Сравнивались региональные объемы головного мозга.</p> <p>РЕЗУЛЬТАТЫ: 207 участников включено в исследование. COVID+ группу составили 24 участника, из которых 4 были госпитализированы вследствие COVID-19. Сравнение выявило наличие статистически значимых различий объемов левого миндалевидного тела (медиана 1199.3 мм<sup>3</sup> у COVID+ vs. 1263.7 мм<sup>3</sup> у COVID-, U=1839.0, p=0,044, тест Манна-Уитни) и правой постцентральной извилины (медиана 8055.5 мм<sup>3</sup> у COVID+ vs. 8434.0 мм<sup>3</sup> у COVID-, U=1821.5, p=0,045, тест Манна-Уитни). При проведении анализа методом случай-контроль у лиц, сопоставленных по полу, возрасту и распространенным соматическим причинам структурных изменений головного мозга, не было выявлено статистически значимых различий между COVID+ и COVID- группами.</p> <p>ЗАКЛЮЧЕНИЕ: Мы не обнаружили значимых свидетельств изменений региональных объемов головного мозга у лиц, перенесших и не перенесших COVID-19. Однако, учитывая имеющиеся ограничения исследования, эти результаты не могут быть перенесены на всех пациентов после COVID-19.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>elderly people</kwd><kwd>MRI</kwd><kwd>brain morphology</kwd><kwd>regional brain volumes</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>SARS-CoV-2</kwd><kwd>пожилые люди</kwd><kwd>МРТ</kwd><kwd>морфология мозга</kwd><kwd>региональные объемы мозга</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">RFFI</institution></institution-wrap></funding-source><award-id>20-04-60546</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Science Foundation grant</institution></institution-wrap></funding-source><award-id>21-71-10136</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Centers for Disease Control and Prevention [Internet].
