If you think Covid-19 is just a respiratory disease, you're wrong.

As
the days go by, it is becoming more and more clear that coronavirus causes a
variety of problems in the human brain and nervous system.
These
include strokes, mental disorders, delirium, delusions, fatigue, and anxiety -
scientists see this list of coronavirus-induced neurological problems not
ending.
The symptoms of coronavirus infection are relatively mild –

many
are complaining that they can't remember much, some are feeling depressed, and
many are not able to concentrate on anything as before.
And
for those who have had a stroke, what the doctors have seen is terrifying.
That was the case with Paul Miller-
Paul
Miller, director of communications at Cambridge University, suffered two
strokes after being infected with the coronavirus.
Consultant
neurologist Dr. treated him after the stroke. Arvind Chandradeva.

He
said the ambulance came with Paul just as he was leaving the hospital to return
home.
"Paul
had an expressionless expression on his face, he could only see to one side, he
couldn't remember how to use his mobile phone, or what his passcode was. “
After
the second stroke, blood could not reach a part of Paul's brain.
Dr.
Chandradeva said that there is an indicator to measure the amount of blood
clotting which is called D-dimer. In healthy people it is less than 300. But in
the case of stroke patients it goes up to 1000.
But
in the case of Paul Miller, it exceeded 80,000, which is almost unbelievable.
"I
have never seen such a thing. In response to the coronavirus infection,
something happened in his body that made his blood clot and become sticky,
”says Dr. Chandradeva.
Dr.
Within two weeks, six people with Kovid-19 were admitted to Chandradeva
Hospital NHNN - who had suffered a stroke. Each of them had severe blood clots.
One
of the reasons for this is: the body's immune system becomes overactive after a
coronavirus infection - causing inflammation in the body and brain.
Doctors
thought 74-year-old Paul Miller might not survive a double stroke, or become
paralyzed. His wife and daughters thought so too. But he has recovered well.
He
can still speak multiple languages well, but can't read as fast as before, and
sometimes he forgets things.
The
Lancet survey
A
survey by The Lancet Psychiatry found brain complications in 125 Covid-19
patients treated at a UK hospital.
About
half of these 125 people had a stroke due to a blood clot, others had
encephalitis, some had symptoms of dementia - some had a mental illness.
Tom
Solomon, a professor at the University of Liverpool who co-authored the report,
said: "We used to think that coronaviruses attack the lungs, but now it's
clear that they can cause brain problems as well."
"One
of the reasons is a lack of oxygen to the brain, in addition to blood clots,
and inflammation caused by over-activation of the immune system. We also need
to ask whether the virus itself is infecting the brain. ”
Canadian
neuroscientist Professor Adrian Owen has launched an online survey that will
lead a worldwide study of how coronaviruses adversely affect cognition.
"Nervous
system disease has been linked to SARS and Mars viruses before - but I've never
seen anything like this in the case of this new coronavirus," said Michael
Jandi, a neurologist at NHNN.
"It
simply came to our notice then. In the 15-20 years after the epidemic, there
were a lot of problems with people with brain diseases. ”
Towards
the end of World War I, in 1918, a mysterious disease called encephalitis
lethargy spread around the world - affecting about one million people.
There
is not much evidence about the cause. This can lead to problems such as
anesthesia and Parkinson's disease in those affected - so that they can suffer
for the rest of their lives.
Care
must be taken to compare the Covid-19 and the Spanish flu of 1917.
But
the symptoms of nervous system problems in Kovid patients are so common that it
is very important to find out what the long-term response will be.
