Brain biomarker evidence was seen more prominently in those experiencing neurological dysfunction in the disease.

The brain damage caused by Covid infection is so dangerous that its symptoms do not go away even after many months of the patient's recovery. British researchers made this claim on the basis of a study conducted on hospitalized patients. He said that this brain damage cannot be detected even by blood test, because the results of the blood test for this are normal.

This study by researchers at the University of Liverpool, published in Nature Communications, reported that during the acute phase of viral infection, when symptoms develop rapidly, inflammatory proteins cause brain damage. In 800 patients from hospitals in England and Wales, it was found that biomarkers associated with brain damage were still present in the patients months after discharge.

Complications even in those with minor symptoms

Brain biomarker evidence was seen more prominently in those experiencing neurological dysfunction in the disease. Researcher Benedict Michael said, many complications were seen even in those who had minor symptoms like headache and myalgia before infection.

Research important for care after infection

According to the researchers, markers of inflammation associated with abnormal immune responses in the acute phase of infection are not captured by blood tests that measure inflammation. These biomarkers provide new targets for medical screening for COVID and other infections that cause acute brain dysfunction. This research is very important for the care of Covid patients after infection, so that the genes can be identified.

Symptoms persist even after recovery

Actually, after the blood test results come back normal, it is considered that the patient has completely recovered. Whereas, studies show that blood tests do not reveal these biomarkers, but the patient is still struggling with symptoms. That is why the patient remains unwell even after recovery.
