Around 80 percent of corona patients who have to be treated in hospital report neurological symptoms such as memory loss.
A medicine could help.
A corona infection can express itself in different ways. Many people are unaware of the illness, while others report flu-like symptoms. In rare cases there may be shortness of breath, thrombosis or other serious complaints that make a hospital stay necessary.
The brain can also be damaged by a corona infection
. According to the specialist portal
Nature
,
researchers report
that around 80 percent of corona patients treated in hospitals show neurological symptoms - from forgetfulness to memory loss and stroke.
The question that
Nature
asks Serena Spudich, a neurologist at Yale University in New Haven, USA, is, "Can we take action early to treat these abnormalities so people
don't
get
long-term problems
?"

Covid-Brain: Corona infection can lead to forgetfulness
New evidence would suggest that the coronavirus attack on the brain is multifaceted. On the one hand, it could attack certain brain cells, so-called astrocytes, directly, according to Arnold Kriegstein, a neurologist at the University of California in San Francisco. "Astrocytes do a lot of things that support normal brain function, including supplying neurons with nutrients to keep them functional," said Kriegstein of Portal
Nature
as quoting: "Infected astrocytes could explain some of the neurological symptoms associated with Covid-19 be associated,
especially fatigue, depression and "brain fog," the confusion and forgetfulness includes.
"
But not only the direct attack of viruses on the cells is discussed. A reduced blood flow to the brain tissue triggered by Covid or the production of immune molecules that can damage brain cells is also possible.
Another way that Sars-CoV-2 attacks the brain is through the so-called pericytes
. These are cells that are found on the outer walls of blood vessels.
According to
Nature
,
scientists from London University College were able
to show that the viruses apparently block the receptors of the pericytes and thus cause the blood vessels to contract.
David Attwell is a neuroscientist at University College London.
According to him, drugs to treat high blood pressure, which cause blood vessels to narrow, are said to be useful in some cases of Covid-19.
Two clinical studies are currently investigating the effectiveness of the blood pressure drug losartan in treating the disease
