A new research study recommends that the coronavirus that triggers COVID-19 might hide in the brain of those infected and trigger relapses in clients who had appeared to be recovering.
In a research study released Tuesday by the journal Viruses, scientists from Georgia State University found that mice infected with the infection through their nasal passages developed serious illness due to brain infection even after the infection had left their lungs. Lead scientist and study co-author Mukesh Kumar suggested that the findings could discuss why human clients who appear to be nearly over the health problem often quickly regression and die.
” The brain is among the areas where virus likes to conceal,” Kumar stated in a news release. “That’s why we’re seeing serious disease and all these numerous signs like heart disease, stroke and all these long-haulers with loss of smell, loss of taste … All of this has to do with the brain rather than with the lungs.”
The research study found that the virus lay in the brains of mice at a level 1,000 times greater than any other location of the body. While levels of the virus located in the lungs began to lessen after 3 days of infection, the infection remained at high levels in the brain on the fifth and 6th days, when the course of the disease became more serious.
” Our thinking that it’s more of a breathing illness is not necessarily true,” Kumar said. “When it contaminates the brain it can impact anything since the brain is controlling your lungs, the heart, everything. The brain is a really delicate organ. It’s the central processing unit for everything.”
In addition to COVID-19, Kumar recommends that the coronavirus reaching the brain could leave patients susceptible to other severe health problems in the future, consisting of neurological conditions like Parkinson’s Disease and Numerous Sclerosis, along with basic cognitive decline and autoimmune diseases. While several research studies have recommended that mice brains are vulnerable to being contaminated by the infection, research study has not produced conclusive proof to support the concept that the virus contaminates and focuses in human brains. Neurological signs could be triggered by an immune reaction rather than a direct brain infection.
A blog post written by National Institutes of Health Director Dr. Francis Collins last week detailed a current study conducted by the National Institute of Neurological Disorders and Stroke that found brain damage in tissue samples from 19 individuals who had actually died from COVID-19 but no proof that the infection had infected the brain tissue itself.
” The findings are especially appealing since there has been some suggestion based on research studies in mice that SARS-CoV-2 might cross the blood-brain barrier and get into the brain,” Collins composed, before keeping in mind that another research study, published in the Journal of Experimental Medication, had discovered evidence of the virus in the brains of 3 people who passed away from COVID-19 issues.
