It is best to assume "everything is correlated with everything else", rather than jump on every correlation. On the other hand it is important to encourage people to notice correlations and coincidences, but realize not every one can be followed up on, and most of these that are noticed will be only weakly involved in any solution.

Really all we know at this point is that Alzheimer's disease is associated with the presence of more stuff that stains with antibodies raised towards Amyloid-beta aggregates than usual. It isn't even clear whether these are a cause or a symptom, nor whether these stains are near 100% specific towards beta-Amyloid (ie as derived from Amyloid precursor protein) rather than other aggregations of beta-sheets (like any prion "infection").

There was a mythical past when Hacker News was much smaller, when (early) downvotes meant something. But that's gone.

A study looking at the rates of Lyne disease and Alzheimer's by state did not find a correlation. States where Lyme disease was more prevalent tended to actually have lower rates of Alzheimer's.

> Like I reject your comment - because it contains no information whatsoever apart from a very short opinion. If your own work is so shoddy, what conclusions can I draw about your criticism of others? A few reasons or a link that states them should have gone with your criticism.

But thank you for uselessly pointing out options. You know, you could have taken a walk, eaten a sandwich, did some random activity, written a comment that's actually useful, or many other things. And yet you chose to write what you did, for some inexplicable reason.

I don't know why you've chosen to be antagonist to both the other commenter and myself. How are you doing in your life? Are you under a lot of stress? Honest question.

Read paper yourself. Google it. Look at the discussion in the previous HN thread, which is referenced in this thread.
