Back on Covid. The Science is clear and not great news. It my be our brains not just our lungs at significant risk[bigsad]
"
Forty percent to 60 percent of hospitalized Covid-19 patients experience neurological and psychiatric symptoms, "
"
The study was posted online on Wednesday and has not yet been vetted by experts for publication. But several researchers said it was careful and elegant, showing in multiple ways that the virus can infect brain cells."
"The coronavirus targets the lungs foremost, but also the kidneys, liver and blood vessels. Still, about half of patients report neurological symptoms, including headaches, confusion and delirium, suggesting the virus may also attack the brain. A new study offers the first clear evidence that, in some people, the coronavirus invades brain cells,
hijacking them to make copies of itself. The virus also seems to suck up all of the oxygen nearby, starving neighboring cells to death. "

It’s unclear which route the pathogen is taking, and whether it does so often enough to explain the symptoms seen in people.“I think this is a case where the scientific data is ahead of the clinical evidence,” Dr. Muotri said.
