Note that tooth decay and gum disease are strongly linked to sugar consumption, high sugar consumption causes diabetes, and Alzheimer has been linked with type 2 diabetes. I don't know how popular this hypothesis is these days, but that's a possible link.

While it may be considered andectoal, this fits with what i've seen in my family. In my mind and from what i've read it seems to be more of a combination of factors - diabetes, an APOE gene, toss in a little depression/loss of purpose/retirement/isolation, etc

I find the studies with gamma interesting: https://www.alzheimers.gov/clinical-trials/gamma-induction-a...

I think it would be good to bring more attention to noticing when things start to slip, because as things progress there can be less openess to trying new things/focus on maintaining state.
