Most of what we know about how COVID can affect the brain has come from studies of people with severe infection. In people with severe COVID, inflammatory cells from outside the brain can enter brain tissue and spread inflammation. There may be changes to blood vessels and brain cells can even have changes similar to those seen in people with Alzheimer’s disease.
However, a new study has investigated the effects of mild COVID (that is, infection that doesn’t lead to a hospital admission) on the brain. The findings may further explain some of the brain changes contributing to long COVID.

Because of the nature of the study, information about the strain of COVID people were infected with was not available. So we can’t assume the findings would be the same for people with the now more prevalent Omicron strain. We also can’t determine the effect vaccination may have in lessening brai...
To show these changes were specific to COVID and not just related to having a respiratory illness, the scientists also looked at a group of people who had pneumonia. They did not see the same changes, confirming they are related to COVID.

Scientists collected data as part of the UK Biobank database. They looked at brain MRI scans and tests of brain function in 785 volunteers who were assessed before the pandemic. They then compared this to the same data collected three years later, when around half of those participa...
Many people who have had COVID, no matter how mjlfreport feelings of “brain fog”, fatigue, and problems with concentration and memory long after their initial symptoms resolve. These problems, collectively known as 'long COVID', may last for months even after mild infection.

Problems with memory and attention are also frequent for people with these diseases and disorders, indicating mild COVID infection may accelerate brain degeneration. These changes could explain the reported symptoms of long COVID, such as brain fog.
The study did not look at the mechanisms ...
This study also only included people aged 51–81, so we do not know whether these findings are relevant for younger people or children.
The brain changes found in this study were more pronounced in the older participants, so it could be that older people are more susceptible. Another study i...
There were some differences between the groups before COVID, with smaller volumes of areas deep within the brain. However, these were in different brain areas to those affected after COVID.
The scientists also found slightly reduced scores for brain functions of thinking and remembering in...
This study provides the first important information about brain changes in people with mild COVID infection. Until we have all the information, we should be alert but not alarmed at emerging findings.
The group who had mild COVID an average of five months beforehand had thinning of brain tissue in several brain regions, ranging from 0.2% to around 2% compared to their pre-COVID scan (between one and six years of normal brain ageing). Affected brain areas included the parahippocampal gyrus (rel...
So does this study prove all people who have had mild COVID infections will have these same brain changes and long-term brain degeneration? Not necessarily.
There are several important things we still do not know. This includes whether these brain changes will get worse over time, or whethe...

Don’t look further if you love learning new things. A refreshing concept that provides quick ideas for busy thought leaders.
Best app ever! You heard it right. This app has helped me get back on my quest to get things done while equipping myself with knowledge everyday.
This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!
Great interesting short snippets of informative articles. Highly recommended to anyone who loves information and lacks patience.
Brilliant. It feels fresh and encouraging. So many interesting pieces of information that are just enough to absorb and apply. So happy I found this.
Great for quick bits of information and interesting ideas around whatever topics you are interested in. Visually, it looks great as well.
Even five minutes a day will improve your thinking. I've come across new ideas and learnt to improve existing ways to become more motivated, confident and happier.
I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
