Researchers find evidence to suggest that COVID-19 can cause brain damage

According to a study by the National Institutes of Health, researchers have found evidence to suggest that brain damage may be a product of COVID-19.

Researchers have discovered vascular damage and inflammation in the brains of 19 deceased COVID-19 patients.

“We found that the brains of patients infected with SARS-CoV-2 may be susceptible to microvascular damage. Our results suggest that it may be caused by the body’s inflammatory response to the virus,” Avindra said. Nath, managing director, clinically said. director at the NIH’s National Institute of Neurological Disorders and Stroke (NINDS).

Nath, the senior author of the study, added that although COVID-19 is mostly known as a respiratory disease, he hopes that this study will help the medical community to identify the extent of the complications that can occur as a result of contracting the deadly coronavirus.

“We hope these results will help physicians understand the full spectrum of problems patients may experience, so that we can come up with better treatments,” Nath said.

In this study, researchers analyzed brain tissue samples from 19 patients who died from complications associated with COVID-19 between March and July 2020. The ages of these patients were between 5 and 73 and they died within hours to two months after they died. reported. coronavirus symptoms, according to the study.

Researchers have noted that many of these patients also had one or more risk factors, including diabetes, obesity, and cardiovascular disease.

After examining the patients’ brain tissue, researchers determined that the damage they identified in the brain was mostly related to strokes or other neurological disorders.

“We were completely amazed. Originally we expected to see damage caused by a lack of oxygen. Instead, we saw multifocal areas of damage that are usually associated with stroke and neuro-inflammatory diseases,” said Dr. Nath said.

Researchers expected to find damage caused by oxygen deficiency, as COVID-19 attacks the lungs and prevents oxygen from reaching other organs that need it to function properly.

“So far, our results suggest that the damage we saw may not have been caused by the SARS-CoV-2 virus that directly infected the brain,” said Dr. Nath said. “In the future, we plan to study how COVID-19 damages the blood vessels of the brain and whether it produces some of the short- and long-term symptoms we see in patients.”

Previous studies have indicated that people infected with COVID-19 may experience other neurological effects.

In a separate study in October among more than 84,000 people, led by Adam Hampshire, a doctor at Imperial College London, researchers found that in some of the worst cases, patients experienced mental decline by 10 years.

Of all patients studied in October, 60 reported being placed in a ventilator, 147 were admitted to hospital but had no ventilator, 176 received medical assistance at home, experienced respiratory problems, 3,466 had respiratory problems had but not medical assistance, and 9,201 were ill without respiratory symptoms. The team said 361 themselves reported that they had a positive biological test.

When analyzing the patients’ data, the authors of the study said that they found a significant cognitive decline in some individuals.[Cognitive deficits] was of great effect size for people admitted to hospital, but also for mild but biologically confirmed cases that reported no respiratory problems, ‘the researchers wrote in a report published on MedRxiv.’ Refined analytical analyzes support the hypothesis that COVID-19 has a multi-system impact on human cognition.

Last month, FOX Television Stations reported an incident involving a child in Missouri who, according to doctors, had a stroke after contracting COVID-19.

Doctors told the parents of three-year-old Colt Parris that they believe the deadly virus is causing a blood clot, leading to a stroke.

“The COVID diagnosis is important because we think the reason why this patient with COVID, including the child, has strokes and a variety of other problems, is that they tend to form blood clots,” said Dr. Neurologist Camilo Gomez said. Gomez also treated Colt.

However, neurological problems are not the only complications associated with COVID-19.

In a study published in September, Ohio State University researchers found that out of more than two dozen university athletes who tested positive for COVID-19, 30% had cellular heart damage and 15% had signs of heart inflammation. caused by a condition. known as myocarditis.

According to the Mayo Clinic, myocarditis is usually caused by a viral infection with symptoms ranging from chest pain, fatigue, shortness of breath, to a negative impact on heart rate and rhythm, as seen in conditions such as arrhythmias.

The US Centers for Disease Control and Prevention tweeted on September 17: ‘Heart conditions such as myocarditis are associated with some cases of # COVID-19. Severe heart damage is rare, but has even occurred in young, healthy people. ‘
