Researchers have revealed that some patients with Covid - 19 are at higher risk of neurological complications like bleeding in the brain and stroke, adding that, these potentially life - threatening findings were more common in hypertension and diabetes patients.
The virus that causes Covid - 19 first attacks cells in the respiratory system, often leading to an inflammation of the lungs that puts people at risk of contracting pneumonia.
But the virus' impact has also been felt in other systems of the body.
"Covid - 19's effects extend far beyond the chest, " said study lead author Colbey W Freeman from the University of Pennsylvania in the US.
"While complications in the brain are rare, they are an increasingly reported and potentially devastating consequence of Covid - 19 infection, " Freeman added.
To learn more about the phenomenon, the research team looked at COVID - 19 patients who underwent head CT and MRI in their health system from January to April 2020.
Of the 1, 357 patients with COVID - 19 admitted to the system in those four months, 81 had a brain scan performed.
The most common reasons for the brain scans were altered mental state and focal neurologic deficits such as speech and vision problems.
Out of 81 patients with brain scans, 18, or just over one in five, had findings that were considered an emergency or critical, including strokes, brain bleeds and blocked blood vessels.
At least half the patients had pre - existing histories of high blood pressure and type 2 diabetes.
