COVID-19 is commonly associated with respiratory symptoms, but it can also wreak havoc on the heart, gut, and nervous system. This is because COVID-19 is primarily a vascular disease, targeting the vascular endothelium that transmits fluids throughout the body. It infects the brain and can cause brain injury markers to show up in the blood. Researchers have found that recovering COVID-19 patients may have markers of brain injury in their blood, even if they appear healthy based on regular blood tests. These markers can indicate the presence of serious neurological conditions, potentially persisting for months after patients recover. Understanding the mechanisms behind brain damage caused by COVID-19 is crucial and could lead to new treatments. Learn more about this study in the article here.
