[Commentary] Infection with the CCP Virus May Cause Brain Tissue Atrophy and Cognitive Functions Decline

Translator: MOS Translation Group — Tang777

After being infected with the CCP virus, the virus may invade neurological and brain tissues, causing neurological and brain function impairments, such as loss of smell and taste, cognitive functions decline, and mood disorders.

In a study [1], it was found that patients infected with the CCP virus, even asymptomatic or mildly infected, showed shrinkage in some areas of the gray matter of the brain when they were examined over time.   

In this study, researchers examined and analyzed the brain gray matter of 120 patients with neurological symptoms changes (including 58 COVID-19 patients and 62 control non- COVID-19 patients, but matched by age, sex, and disease) observed under computed tomography. The results found that even when the cerebrovascular disease is well controlled, at the time of discharge and the six-month follow-up period, it can be found in patients with severe residual disease and patients who need oxygen therapy during the disease.  

In addition, in patients who have had fever during the disease, the volume of gray matter in the temporal gyrus and fusiform gyrus of the brain will decrease. The volume of gray matter in the frontal lobe of the brain will also decrease in patients who have had symptoms of agitation. This observation shows that after being infected by the CCP virus, changes in fever or hypoxia may secondarily affect the operation of the frontotemporal neural network of the brain. 

In another long-term study [2] it was also shown that over time, x- survivors of the CCP virus infection may experience a reduction in brain gray matter and other brain tissues.

This study used data collected by the British Bio-bank for analysis. A total of 782 volunteers ’data was collected to compare brain scans of individuals before the COVID-19 pandemic. Then, 394 survivors of COVID-19 infection and 388 healthy volunteers were invited to return for follow-up brain CT (computed tomography) scans.

Among the volunteers who recovered from the COVID-19 virus infection, the researchers found that the COVID-19 virus has a significant effect on the human cerebral cortex, and the gray matter in the brain area is reduced.

The results of the study revealed a decrease in gray matter in the limbic cortical areas of the brain directly related to the primary olfactory and gustatory systems. 

The gray matter portion of the brain is formed by the aggregations of brain nerve cells that function to enable individuals to control movement, memory, and emotions. Therefore, the reduction of brain gray matter will affect the function of that area of the brain.

This study also showed that there was a decrease in gray matter in areas of the brain associated with memory function. This change may increase the risk of developing dementia in the future in these patients. 

In contrast, no changes in brain gray matter were observed in healthy control volunteers. Most survivors of COVID-19 infection in these participating studies had only mild to moderate symptoms or no symptoms at all at the time of onset.

Therefore, even if it is a mild COVID-19 patient, it does not mean that the brain will not be damaged, which is a matter of concern.

There is another study on brain function after infection with COVID-19 [3], collected 81,337 volunteers who underwent a clinically validated web-optimized assessment between January 2020 and December 2020 as part of the UK IQ test, in which researchers captured suspected and confirmed COVID-19 infection from responses to questionnaire items and cases presenting with respiratory symptoms.

The results of this study found that individuals who recovered from COVID-19 infection showed significant cognitive deficits. This phenomenon of cognitive deficit was not only significant in hospitalized patients (N = 192), but also in non-hospitalized patients (N = 326) who were tested and confirmed to be infected with COVID-19. Analysis of these patients’ intellectual markers prior to the onset of the disease does not support the hypothesis that these differences existed in these volunteers prior to being infected. The results of the analysis of more detailed and itemized functional tests support the hypothesis that the COVID-19 virus infection has a multi-faceted impact on human cognitive function.

In summary, even patients who are asymptomatic or with mild to moderate symptoms after being infected with the CCP virus may still suffer from brain damage and dysfunction after recovery. This presents how vicious this biochemical weapon and the CCP virus are. The world must ask the CCP to hand over the truth about the virus to find a thorough way to prevent and treat it.
