> Although the neuroinvasion of SARS-CoV-2 has been demonstrated with confirmation of the virus in some brain autopsies, the neural mechanisms underlying both neurological and neuropsychiatric symptoms (acute and chronic) remain unclear.

The spike protein present in both SARS-CoV-2 virus and Covid vaccines contains amyloidogenic epitopes that might be behind those collections of symptoms. There is no safe dose of prions in the brain.
