UK scientists find link between proteins related to blood clots and long Covid

Biomarker discovery indicates that sufferers from brain fog and fatigue post-virus could be treated with anticoagulants

Scientists have identified molecular signatures in the blood that are linked to brain fog, other cognitive problems and fatigue in patients who are diagnosed with long Covid after catching the virus.

Raised levels of two different proteins were more common in people who developed long Covid symptoms that affected their brains, the researchers found. Both are hallmarks of blood clots in the body, the likely cause of the symptoms reported.
