Long COVID linked to brain fog

Researchers admit that there is still more to learn about long COVID and it’s effects on the brain.

A new study finds that some preexisting risk factors may make some more likely to get long COVID. Diabetes, anxiety, or depression, are all potential risk factors.

There are other cognitive side effects linked to long COVID

Post-COVID cognitive symptoms and abnormalities in the cerebrospinal fluid were found to be linked. The abnormalities usually include antibodies. This suggests that these cognitive symptoms could be caused by increased  inflammation. More information can be found here.

These results may be a clue to understanding predisposing factors.

Difficulty maintaining attention, as well as deficits in memory and executive function are also cognitive symptoms consistent with long COVID.

More than 3 in 4 individuals experiencing cognitive symptoms had abnormalities in their cerebrospinal fluid, and those abnormalities were absent in the control group.

The antibodies indicate activation of the immune system and inflammation of the brain. This response could potentially be occurring in your entire body.

Although this study contains lots of valuable information, the size of the study might limit the validity of the results. This study would best be replicated on a larger scale for more accurate information.
