Long COVID fatigue and brain fog have a possible biological explanation. This marker is tied to fatigue and memory problems. PET scans link long COVID to changes in the dopamine system.

The research suggests that long COVID may be related to a disruption in the normal functioning of the brain's reward system. ScienceDaily also reports on this research, stating that brain scans reveal a possible cause of long COVID fatigue and brain fog. However, it's essential to note that this research is still in its early stages.

While the findings are promising, more studies are needed to confirm the link between long COVID and dopamine levels. The Sick Times provides an update on the research, but the article does not delve into the specifics of the study's methodology or potential limitations. Martin Cid Magazine and UA.NEWS also cover the story, but their reports focus on the potential implications of the research rather than the details of the study itself.
