Stanford study finds inflammation in brains of deceased COVID-19 patients

• by Rich Haridy

Although no trace of the SARS-CoV-2 virus could be detected, "profound molecular markers of inflammation" were seen, offering clues as to why some patients suffer expansive neurological symptoms following infection.Stanford neuroscientist Tony Wyss-Coray is perhaps best known for his work transferring plasma from young mice into old mice and discovering it can reverse age-related cognitive decline. Those infamous studies inspired a variety of controversial companies promising to reverse aging through transfusions of young blood.Wyss-Coray is still investigating exactly what mechanism can explain the mouse findings, and no evidence has yet appeared to show young blood confers those same beneficial effects in humans. One hypothesis is that inflammatory responses in the brain can be triggered by factors in the blood outside of the brain.
