Brain fog after Covid linked to blood clots - study
A UK study suggests that blood clots in the brain or lungs might explain common symptoms of "long Covid" like brain fog and fatigue. The study found that two blood proteins, fibrinogen and D-dimer, are associated with cognitive problems in Covid patients.
The research team emphasized that their findings are relevant only to patients admitted to the hospital and that further research is needed to propose or test potential treatments. They also noted that there may be multiple causes of long Covid.
A survivor of severe Covid is still experiencing problems with concentration and memory loss. The study, along with a similar US study, supports the hypothesis that blood clots are a cause of post-Covid cognitive problems.
