British neuropsychiatric researchers have identified two biochemical markers that accompany the handicapping cognitive impairments associated with Long CoVid. Studying 1,837 hospitalized CoVid patients on a longitudinal basis, they discovered that elevated fibrinogen and D-dimer levels in such patients predict the development of CoVid “brain fog” 6 and 12 months later. Fibrinogen is blood clot precursor, and D-dimer is a byproduct of blood clot dissolution. The levels of these proteins are both elevated during CoVid in relation to a measure of inflammation, C-reactive protein. We already know that CoVid infections tend to hyper stimulate both blood clotting and inflammation, and this latest finding suggests that brain damage with associated CoVid brain fog is somehow related to clotting overactivity. Controlling this process may disperse the fog…..someday soon.
