Anecdotal evidence doesn't help you. Observations can find a trend, which can be further studied. The disease is complex, there are likely multiple factors. Think of cancer, some people smoked for decades and never got it, others died young. Doesn't mean smoking doesn't cause lung cancer

Yeah, I don't deny that observational studies have value. I meant this study is "generally worthless" because all of the findings have longstanding, well-known correlations to cognitive health.

As always, all of the findings indicate poverty/wealth as the greatest underlying risk/protective, so at this point it's beating a dead horse.
