Dr. Scott Gottlieb cautioned Thursday about the potential for long-lasting brain loss associated with Covid, pointing out a brand-new study from the United Kingdom.”You might compensate for that over time, so the signs of that might go away, but youre never ever going to restore the tissue if, in reality, its being ruined as an outcome of the virus,” said Gottlieb, who serves on the board of Covid vaccine-maker Pfizer.”The diminishment in the quantity of cortical tissue happened to be in regions of the brain that are close to the locations that are accountable for smell,” he said.
