claim: sars-cov-2 spike proteins disrupt the blood-brain barrier, potentially reducing risk of neurological damage in covid-19 patients
evidence_1: the study, published in the december print issue of the journal neurobiology of disease, is the first to show that sars-cov-2 spike proteins can cause this barrier to become leaky, potentially disrupting the delicate neural networks within the brain.", "our findings support the implication that sars-cov-2, or its shed spike proteins circulating in the blood stream, could cause destabilization of the blood-brain barrier in key brain regions, dr. ramirez said.", "moreover, as dr. buzhdygan explained, the brain vasculature is extremely branched, so even a small amount of neuroinflammation can be very damaging. based on the team's observations of ace2 expression in the brain, this neurological damage could be extensive in covid-19 patients with pre-existing health conditions in which the vasculature has already suffered some amount of injury."
