From the article: "A report in the July 2020 issue of The Lancet listed the variety of known risk factors for dementia, ranging from air pollution to repetitive head trauma to systemic infections."
The article doesn't mention diabetes or sugar.
Actually, that 2020 report[0] does mention diabetes:
>Overall, a growing body of evidence supports the nine potentially modifiable risk factors for dementia modelled by the 2017 Lancet Commission on dementia prevention, intervention, and care: less education, hypertension, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and low social contact.
There's also a lot of research out there that links diabetes to inflammation. Inflammation can be due to diet (chemical derangement) or infection or both. Inflammation is implicated in a lot of brain issues as well.
I'm aware that the parent article doesn't refer to diabetes. I never said it did. As a general comment regarding this disease I shared what my current state of mind on this was. Is there a link between diabetes and the mechanism explored in the parent, maybe? I don't know. But maybe, just maybe, if enough paths are explored we'll eventually find the right one. Diabetes seems to be an interesting one for me ... but I'm by no means an expert. Just an interested observer that is doing a genuine effort to understand.
