Long COVID has been a persistent and debilitating condition for many individuals who have recovered from the initial infection of COVID-19. One of the most common symptoms reported by these patients is brain fog, which can include memory and concentration problems. Now, scientists have made a groundbreaking discovery that may explain the cause of this symptom.
A new study in Nature Neuroscience links long COVID brain fog to brain blood vessel damage. Researchers at Trinity College Dublin did this study. They used MRI scans on 32 people. Some had recovered from COVID-19, others had long COVID symptoms. The study found that dye leaked into the brains of those with brain fog. This dye pooled in parts of the brain that affect language, memory, mood, and vision.
Exploring the Biological Basis of Long COVID Brain Fog
Scientists have found a direct link for the first time. The link is between long COVID brain fog and leaky blood-brain barriers. The blood-brain barrier protects the brain. It has tightly knit cells along blood vessels. These cells keep harmful substances out of the brain. But, if the barrier breaks down, viruses and harmful particles can get into the brain. This can cause damage to the brain’s tissues.
Geneticist Matthew Campbell led a study proving that brain fog is biologically based. This is important because it means patients can get validated and treated properly by doctors who might not believe them otherwise.
The research team from Trinity College Dublin decided to study this after finding that head injuries can damage the blood brain barrier and cause cognitive issues. They compared these injuries to long COVID symptoms and found a link. This shows that blood vessel damage causes brain fog in long COVID patients.
This is the first study to confirm that SARS-CoV-2 can cause long-lasting brain issues. The researchers hope this leads to more studies and better treatments for long COVID brain fog.
If you have brain fog from long COVID, there’s scientific proof of your symptoms now. It’s also a reminder to look after our brains and protect them. Stay safe and informed.
