I know quite a few people who got shingles in their early 20s. One of their doctors didn’t believe she had shingles until the blisters formed. The vaccine can definitely help those younger than 50, dementia benefits or not. Some of them have permanent nerve damage after getting shingles.
So if you had shingles in your youth then you are better protected against dementia?
The article says that one possible reason the vaccine protects against dementia is incidental protection from other diseases. Getting chickenpox as a kid might protect you against shingles, but maybe not against those other diseases.

That’s possible (although the plaque hypothesis as the sole cause is looking less plausible). But that’s not what the study is saying. It’s literally just saying that older doctors are more likely than younger doctors to have dementia. Also that study only looks at dementia and Alzheimer’s only accounts for ~2/3 of cases.
Plaque is the end-cause. What's debatable is why it accumulates and what pharmaceuticals and interventions we doctors should prescribe for our patients, not whether it's present or not.

Isn't cholesterol released into the bloodstream to protect arteries when it gets acidic, and over time turning into plaque buildup? Also, going the other way doesn't help either because if you got a spike in acid your arteries wouldn't cope with the overload
