Wow, lots to chew on here. Some questions that come up:
- Most people with long Covid brain fog were not hospitalized. We’re people with these symptoms looked at specifically?
- The early strains seem to have wreaked more havoc systemically than current strains, even having different cell predilections. We’re the data based on infections in first 18 months of pandemic?

- it would be interesting to see how Covid interacted with other dementia risk factors, including apoE genotype.

- Effect of vaccination status?
