A new study published in the journal Nature has revealed yet another long-term effect of COVID-19. The research showed that even those with mild disease had a significant reduction in gray matter in their brains.
Although the coronavirus continues to infect hundreds of thousands of people every day all over the world, new mutations of the virus do not cause severe disease compared to previous mutations. But the virus still continues to be full of mysteries for the scientific world. Part of this mystery is caused by the coronavirus. Long-term effects of COVID-19 disease.
Some studies to date have shown that COVID-19 can even lead to shrinkage in the brain in the long term. A new study published in the journal Nature revealed a more serious and frightening result. research in the brain in the amount of gray matter there has been a significant decrease showed.
Gray matter decreases, brain shrinks, cortex associated with smell is damaged
In the study, which was conducted on 785 UK Biobank participants aged 51-81, 401 people with COVID-19 and 385 controls were examined. These people pre-infection and brain imaging after infection viewed. The images showed that the amount of gray matter in the brain was markedly reduced.
In addition to the reduction in the amount of gray matter, COVID-19 is detected in the primary olfactory cortex, which is associated with smell in the brain. changes that indicate tissue damage observed. However, the research has also proven once again that there is a significant reduction in the brain. Beyond that, the patients studied in the study were mostly Nor were the patients who had severe COVID-19.
Of the 401 patients included in the study who had COVID-19 only 15 of hospitalized patients consisted of.
