Prime News, International, Health, Disease, New Delhi, June 24:- Scientists have found signs of inflammation and neurodegeneration in the brains of individuals who died of COVID-19, similar to what is observed in people who die of conditions such as Alzheimer’s and Parkinson’s disease.
The findings by researchers at the Stanford School of Medicine, US, and Saarland University in Germany may help explain why many COVID-19 patients report neurological problems.
These complaints increase with more severe cases of COVID-19 and can persist as an aspect of “long COVID,” a long-lasting disorder that sometimes arises following infection with SARS-CoV-2, the virus that causes COVID-19.
About one-third of individuals hospitalised for COVID-19 report symptoms of fuzzy thinking, forgetfulness, difficulty concentrating and depression, said Tony Wyss-Coray, a professor at Stanford.
The researchers could not find any signs of SARS-CoV-2 in brain tissue they obtained from eight individuals who died of the disease. Brain samples from 14 people who died of other causes were used as controls for the study.
“The brains of patients who died from severe COVID-19 showed profound molecular markers of inflammation, even though those patients didn’t have any reported clinical signs of neurological impairment,” said Wyss-Coray. (MR, Inputs: Agencies)
