Scientists warn that brain damage may be related to Covid-19

 


An expert at University College London (UCL) was the latest patient to explain that Covid-19 can cause neurological complications such as stroke, neuropathy, and deadly brain inflammation. ..

“We need to be vigilant and aware of these complications in people who have experienced Covid-19,” said co-author Dr. Michael Zandi. UCL Press Release, “Is there an epidemic in large-scale brain damage related to pandemics?”

They said follow-up is needed to understand the potential long-term neurological consequences of the pandemic.

This study, published in the journal Brain, examined 43 patients treated at the University College London Hospital for either confirmed or suspected coronavirus between April and May. Ages ranged from 16 to 85 years with mild to severe symptoms.

Among these patients, the researchers found 10 cases of “temporary brain dysfunction” and delirium. 12 cases of cerebral inflammation; 8 cases of stroke; and 8 cases of nerve damage.

Most patients with cerebral inflammation were diagnosed with a specific, rarely fatal condition known as acute disseminated encephalomyelitis (ADEM). Prior to the pandemic, the London research team examined about one ADEM patient each month. During the survey period, the number increased to at least once a week.

A woman hallucinated a lion and a monkey in her home. Others reported numbness in the limbs and face, diplopia, and disorientation. One of the severe patients was almost unconscious and responded only when there was pain.

Brain scan from the University College London study published on July 8.

Researchers are trying to pinpoint why Covid-19 patients develop these brain complications. The virus that causes Covid-19 was not found in their brain fluid. That is, the virus does not seem to directly attack the brain. Instead, one theory is that the complication is indirectly caused by the immune response from the patient’s body, not the virus itself.

These findings are important to inform physicians around the world how to monitor and treat patients, but they also raise new questions and challenges. For patients who do not have severe respiratory symptoms such as dyspnea, it can be difficult to identify these brain complications early enough to prevent or minimize damage. And for critically ill patients, their precarious health can limit the amount doctors can do to investigate what’s happening in their brains.

The authors warned that future research would be “essential” in figuring out exactly how the virus causes brain damage and how it is treated.

I got Covid-19 two months ago.  We are still discovering new areas of damage

In a press release, co-presenter Dr. Ross Paterson said, “It’s only a few months since the disease started, so it’s possible that we still don’t know what Covid-19 could bring. There is.” “Physicians need to be aware of possible neurological consequences because early diagnosis can improve patient outcomes.”

Dr. David Strain of the School of Medicine, University of Exeter, who was not part of the study, said this finding was important, but “not surprising,” given earlier coronavirus cases.

“The main limitation is that we don’t know the denominator, so we don’t know how often these complications will occur,” said a Wednesday statement. “We’ve already seen that some people using Covid-19 may need both physical and cerebral rehabilitation, such as exercise. I need to understand.”
