COVID-19 Can Damage Blood Vessels in The Brain, Causing Neurological Symptoms

A new study found that COVID-19 may cause brain damage, resulting in cognitive impairment.
Researchers from France, Spain and Germany conducted the study. They found that COVID-19 could kill endothelial brain cells.

Research has shown that as many as 84 percent of COVID-19 sufferers have neurological symptoms. This includes anosmia (loss or sense of smell), epileptic seizures and strokes.

Yelena Dahanova, Insider's reporter, previously reported on how COVID-19 patients experience memory loss even months after contracting it.

The brains of COVID-19-related deaths were scanned.

String vessels were found to be a sign that a dead cell cannot allow blood flow. This is known as cognitive impairment and can lead to a variety of medical risks including micro strokes.

However, there is hope that this new aspect of COVID-19 can be reversed.

"We have observed that in hamsters who develop very minor forms COVID-19, we have seen that the phenomenon is apparently reverseable, so it's possible that it could also reversible in people," Vincent Prvot from Lille's Inserm research centre, co-author of this paper, told RFI News.
