COVID-19 Can Cause Long-Lasting Brain Injury, New Study Reveals

Markers of brain injury continue to be present in the blood many months after Covid-19 infection, despite inflammation blood tests being normal, finds a study.

According to a study, blood tests for inflammation are normal even months after Covid-19 infection, but brain injury markers are still detectable.

The study found persistent indicators of brain injury in individuals who experienced neurological problems during COVID-19, and it was published in the journal Nature Communications.

It was discovered during the Covid-19 pandemic that a sizable percentage of hospitalized patients—including those with moderate Covid-19 infection—were experiencing neurological problems.

According to researchers from the University of Liverpool in the UK, while some neurological “symptoms” were often mild {headache and muscle aches (myalgia)}, it soon became apparent that more serious and potentially fatal new neurological “complications” were happening, such as encephalitis (brain inflammation), seizures, and stroke.

The group examined samples from more over eight hundred Covid-19 hospitalized patients in Wales and England, half of whom had recently developed neurological disorders.

The researchers examined antibodies, brain (neuroglial) injury proteins, serum inflammatory proteins (cytokines), and brain injury markers.

The examination of these reveals that while there is production of important inflammatory proteins and brain injury markers during the acute phase (when symptoms are developing quickly), there is also surprisingly persistent robust biomarker evidence of brain (neuroglial) injury in Covid even months after hospital discharge.

Crucially, this persisted in patients who had experienced acute neurological difficulties during the recovery period and was more pronounced in those who had neurological dysfunction during the acute phase of the illness.

The researchers hypothesise that these inflammatory markers could serve as targets for treatment for Covid-19 and other diseases that cause acute brain dysfunction since they are linked to aberrant immune responses during the acute phase of the disease.

“Our research demonstrates that, even when the inflammatory response in the blood resolves, indicators of brain damage are still seen in the blood months after COVID-19, especially in those who have experienced a COVID-19-related brain problem (such as inflammation or stroke). According to Professor Benedict Michael, primary investigator and head of the University of Liverpool in the United Kingdom, “this suggests the possibility of ongoing inflammation and injury inside the brain itself which may not be detected by blood tests for inflammation.”

Through the integration of immunology, neurology, and infection research, several biomarkers linked to the neurological consequences of Covid-19 were identified. Professor Leonie Taams of King’s College London continued, “This work may help set the stage for elucidating the possible underlying mechanisms of these complications.”
