Can Covid cause brain damage – even mild cases can cause shrinkage according to new study

Scientists have found that Covid can have an impact on the brain size of people with the disease. But can covid cause brain damage and what are the long-term Covid symptoms?

A new Oxford study has found a disturbing link between brain size and Covid

Brain fog has become a common complaint among covid survivors around the world, as confusion and lack of focus remain a persistent symptom of the virus.

And now scientists from University of Oxford found amazing evidence that Covid can have a lasting impact on the brains of people with the disease.

Published in the journal Nature, the study, which looked at MRI scans from around the time of infection, found significant differences in brain images taken before and after the illness.

The researchers couldn’t tell if the changes were permanent, but did reiterate that the brain has the ability to heal over time.

Professor Douaud Gwenaelle from the University said: “We need to keep in mind that the brain is actually plastic – meaning it can heal itself – so there’s a really good chance that over time, harm is done. of infection will decrease,” said Professor Douaud Gwenaelle from the University of Oxford BBC.

The study found that even after a mild Covid infection, the overall size of the brains scanned in the study shrank slightly during the infection.

The image shows that there is less gray matter in parts of the The brain is responsible for memory and smell.

The scientists re-scanned the brains of 401 participants 4.5 months after they had the infection (96% of them had ‘mild Covid).

They compared these images with the brains of 384 people without Covid.

Results found:

  • Overall brain size in infected patients has shrunk by 0.2 to 2%
  • Gray matter is lost in the olfactory area, involved in the sense of smell
  • Gray matter is also lost in regions associated with memory
  • People who have recently recovered from Covid find it a little harder to perform mental tasks

The results showed that the most significant changes occurred in the olfactory region, which may explain the persistently distorted human sense of smell.

Professor Masud Husain from the University of Oxford said: “We still do not understand the mechanism underlying these cognitive impairments, but it is encouraging to see that these memory and attention deficits largely return to normal usually in most of the people we examined after 6-9 months. after infection, who have demonstrated good resilience over time. ”

NHS Announcement has helpful advice for people experiencing brain fog.

A recent study published in Fingertips interviewed 3,762 people about their persistent bulging eye symptoms, finding that 88% had some kind of brain fog or problems with their memory.

However, if you have Covid, you may experience many side effects beyond loss of brain function.

According to NHSCommon lingering COVID symptoms include:

  • extremely tired (tired)
  • shortness of breath
  • chest pain or tightness
  • problems with memory and concentration (“brain fog”)
  • trouble sleeping (insomnia)
  • heart beat fast
  • dizzy
  • pins and needles
  • athritis
  • depression and anxiety
  • tinnitus, ear pain
  • feeling nauseous, diarrhea, stomachache, loss of appetite
  • high temperature, cough, headache, sore throat, change in smell or taste
  • rash
