A small study from the U.S. National Institutes of Health says it has anti-inflammatory properties Response Covad-19 infection can damage the blood vessels of the brain. The reaction can cause Neurological Problems known as long COVID.
In the study, researchers looked at brain changes in nine people who died suddenly after being infected with the SARS-CoV-2 virus COVID-19. The results were published last week. Brain.
Damage to the blood vessels of the brain
The researchers said that antibodies – proteins produced by the immune system to fight viruses – are involved in the attack on cells in the bloodstream of the brain. Ships. This results Swelling And injury.
The results were the same as one. Previous study Done by 2020.
In both studies, SARS-CoV-2 was not found in patients’ brains. This indicates that the virus is not directly affecting the brain.
NIH scientist Avindra is the lead researcher. “We have seen vascular damage and autopsies in patients, but we do not understand the cause of the damage,” he said. A post-mortem is a post-mortem to determine the cause of death.
For the study, Dr. Nat and a team of researchers examined brain tissue in nine individuals between the ages of 24 and 73. The searches were compared with 10 individuals in the control group.
Researchers have found that antibodies produced to fight CV-19 can mistakenly attack cells in the brain’s blood vessels. These cells, called endothelial cells, serve as a barrier to the entry of harmful substances into the brain. Damage to cells causes bleeding and clogging in some covad-19 patients and increases the risk Stroke.
In a previous study, researchers found signs of bleeding. This indicates that the bond between the endothelial cells in the blood-brain barrier is damaged.
According to Dr. Nat, the leaks are caused by immune cells ”It can come in to repair the damage by causing swelling in the brain.
Symptoms of chronic neuropathy
Researchers have found changes in gene expression in areas where endothelial cells are damaged. The expression of more than 300 genes has been reduced, and six genes have expressed expression. Affected genes are linked to the brain’s ability to cope with chemical imbalances in the body.
Together, these findings may provide information on the causes of covad-19 neurological problems. The findings could be used to find new treatments to target damaged connections between endothelial cells in the blood-brain barrier.
The study helps to understand and treat long-term neurological conditions after covad-19. These include headaches, fatigue, loss of taste and smell, sleep problems, and memory problems known as “brain fog.”
The researchers believe that if nine patients survive, long cobwebs may be produced.
“It could be a similar reaction. to be continued In long-term covide patients, ”said Dr. He added that the findings are “very important” for researchers seeking long-term cobweb treatment.
