Long COVID brain fog may be linked to leaky blood vessels in the brain, research finds. Here, experts explain the blood-brain barrier and COVID connection. Scientists May Have Discovered What ...
There is ongoing research about the short- and long-term damage COVID-19 may possibly cause to the brain. [36] including in cases of 'long COVID'. For instance, a study showed how COVID-19 may cause microvascular brain pathology and endothelial cell-death, disrupting the blood–brain barrier.
Long COVID damage can linger for 2 years, leading to elevated risk of disability, hospitalization, and death, landmark new study finds Erin Prater August 21, 2023 at 11:00 AM
Fibrinoid necrosis is a pathological lesion that affects blood vessels, and is characterized by the occurrence of endothelial damage, followed by leakage of plasma proteins, including fibrinogen, from the vessel lumen; these proteins infiltrate and deposit within the vessel walls, where fibrin polymerization subsequently ensues.
Blood vessel dysfunction and clot formation (as suggested by high D-dimer levels caused by blood clots) may have a significant role in mortality, incidents of clots leading to pulmonary embolisms, and ischaemic events (strokes) within the brain found as complications leading to death in people infected with COVID‑19.

A study looking at ultra-detailed MRI scans of people hospitalized with severe COVID-19 found that the disease affects the brainstem, a region of the brain responsible for controlling many key ...
For the Netherlands, based on overall excess mortality, an estimated 20,000 people died from COVID-19 in 2020, [10] while only the death of 11,525 identified COVID-19 cases was registered. [9] The official count of COVID-19 deaths as of December 2021 is slightly more than 5.4 million, according to World Health Organization's report in May 2022 ...
COVID-19 has significantly fallen as a leading cause of death in the U.S. for the first time since the pandemic began, according to new provisional data published Thursday from the Centers for ...
