Long COVID study suggests lost connections between neurons may explain cognitive symptoms

Posted by in categories: biotech/medical, neuroscience

For a portion of people who get COVID, symptoms continue for months or even years after the initial infection. This is commonly referred to as “long COVID”.

Some people with long COVID complain of “brain fog”, which includes a wide variety of cognitive symptoms affecting memory, concentration, sleep and speech. There’s also growing concern about findings that people who have had COVID are at increased risk of developing brain disorders, such as dementia.

Scientists are working to understand how exactly a COVID infection affects the human brain. But this is difficult to study, because we can’t experiment on living people’s brains. One way around this is to create organoids, which are miniature organs grown from stem cells.
