Could an inexpensive vaccine help stave off dementia? - Dementia has long resisted treatment. But one answer could be surprisingly simple.

It's the shingles shot again.

this week delivered one of the brightest spots in an otherwise dark field. According to a study that followed more than 280,000 people in Wales, older adults who received a vaccine against shingles were 20 percent less likely to develop dementia in the seven years that followed vaccination than those who did not receive the vaccine.

This could be a big deal. There are very few, if any, treatments that can prevent or slow down dementia, beyond good lifestyle habits like getting enough sleep and exercise. The possibility that a known, inexpensive vaccine could offer real protection is enormously meaningful. We have good reason to be confident in the findings: While this study is perhaps the most prominent to show the protective effects of the shingles vaccine, other studies of the vaccine have come to similar conclusions.

But the one answer could be surprisingly clickbaity. And I expect the article very dissapointing

Nope.

First you need to find the actual cause of dementia. This “could have” bullshit nonsense doesn’t help anything.
