> like the more colds you have in life

Whoa wait what? This is the first time I’ve heard of this - is this actually common knowledge?

Not common knowledge, but should be in this day and age. For example, someone who worked in daycare and often got sick with the flu or similar, has a higher risk of dementia (statistically-speaking).

When I learned it, it was in the context of the influenza and similar common viruses.

It's actually more nuanced than that. If you want to read more: https://www.openevidence.com/ask/bccc3cc2-e15d-4fb0-a0c5-16f...

		As far as I know you're vastly overstating what is known. There was a study that showed that people who had severe influenza (they were hospitalized) were 3 times more likely to develop dementia. And there are mouse models that show that frequency respiratory virus infections can increase may contribute to brain aging (in mice). >someone who worked in daycare and often got sick with the flu or similar, has a higher risk of dementia (statistically-speaking). I can't find any evidence of this being true. I can find evidence that primary school teachers have lower rates of dementia. Pediatricians also have lower rates of dementia, so I find this highly doubtful.
