A study carried out in Oxford that aimed to determine possible injuries in the brain of people who had had mild COVID-19, has recently been published in the prestigious journal Nature<\/a><\/strong>.<\/p>\n\n\n\n

Patients with COVID-19 may experience loss of smell and taste<\/strong>, headaches, and memory problems. These symptoms are related to a possible infection of the brain by the coronavirus. The study included 401 people with COVID-19 for whom a brain scan was available before infection. Of them, 96% suffered a mild disease and had a second brain scan 4.5 months after COVID-19 diagnosis. On the other hand, they included a control group of 384 people who had a previous scanner and who did not have COVID-19. This control group (with characteristics similar to the study group) also underwent a second scan.<\/p>\n\n\n\n

Decrease in complex skills<\/strong><\/h2>\n\n\n\n

In patients who had passed COVID-19, changes were found between the first and second scans, which were not seen in the control group. Thus, a loss of gray matter thickness was observed in the brain areas that are related to smell. Regarding cognitive skills, the study group had a decrease in the ability to perform complex tasks<\/strong>. Healthy people typically lose between 0.2% and 0.3% of memory-related gray matter annually. People who had COVID-19 had an
additional 0.2-3% gray matter loss<\/strong>. In 11 people in the control group who had other respiratory infections<\/a><\/strong>, these brain changes were not detected, suggesting that the study\u2019s findings are specific to COVID-19.<\/p>\n\n\n\n

In summary, this study has shown that in COVID-19 patients (even with mild disease) lesions in the brain can occur. However, it is unknown if all coronavirus variants can induce these alterations. In addition, these injuries brain<\/strong> changes may disappear over time, so it is very important to monitor these patients.<\/p>\n","protected":false},"excerpt":{"rendered":"We analyze the study published in Nature magazine on brain injuries caused by COVID-19.","protected":false},"author":1,"featured_media":3733,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1541,621],"tags":[],"class_list":["post-3742","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-covid-19-en","category-news"],"acf":[],"yoast_head":"\nBrain injuries caused by COVID-19 -
