Evidence that a COVID-19 infection can induce neurological sequelae.

The SARSCoV2 spike protein can persist in the brain—skull bone marrow and meninges—to induce neurologic damage

SARS-CoV-2 spike protein accumulates & persists in the body for years after infection, especially in the skull-meninges-brain axis, potentially driving long COVID. mRNA vaccines help but cannot stop it.

In mice, it caused inflammation, anxiety, and worsened brain injuries. Vaccines reduced but did not fully eliminate it.

“The Omicron variant of SARS-CoV-2 presents a wide spectrum of neurological manifestations."

"Although there is an improvement in the survival rate of patients with COVID-19, the frequency of neurological manifestations increases."

"The occurrence of delirium, cerebrovascular diseases, and ischemic stroke results in higher mortality."

Nearly half of those infected with SARS-CoV-2 experience long-term neurological problems, including brain fog and memory issues.

An infection may accelerate or exacerbate prion diseases like Creutzfeldt–Jakob disease, leading to rapid neurodegeneration.

Covid itself causes cognitive impairment. From 2020, prior to Covid vaccination of any kind:

“In our cohort of COVID-19 patients neurologic manifestations were frequent, including cognitive impairment.”

Yet another stretch for one size fits all explanation of a multifaceted condition. Still, important finding:

“A groundbreaking study from the University of Colorado Boulder has uncovered a potential mechanism behind the persistent neurological symptoms experienced by many Long COVID sufferers. The research, published in Brain, Behavior, and Immunity, points to a significant drop in cortisol levels in the brain as a possible culprit, offering new insights into this complex and widespread condition.”
