Summary:

- The study found that the spike proteins from the SARS-CoV-2 virus can persist in the brain for years after the initial infection, potentially contributing to long-term neurological symptoms associated with Long COVID.
- Researchers detected the presence of spike proteins in the brains of individuals who had died from COVID-19, even up to 15 months after their initial infection.
- The findings suggest that the persistence of spike proteins in the brain may be a key factor in the development of neurological complications in Long COVID patients, highlighting the need for further research and potential therapeutic interventions.
