ok, now do the proper controlled study comparing coffee to any other stimulant.

Stimulants like caffeine improve scores in cognition assays. Another 💩 study.

The primary outcome was dementia, which was identified via death records and physician diagnoses.

If caffeine has enough of an effect to change a diagnosis or death record, that seems worth reporting in any case.

And while it might be worthwhile to see if other stimulants have a similar effect, does it affect these results one way or the other?

That is not new, caffeine is an analog of ATP and known to affect serum cholesterol levels in the liver. Welcome to 1996.

Epidemiology is a fucking joke. We waste millions on studies making the same observations over and over then the media treats this like it's profound and new.

How many studies do we need to show obesity makes every disease worse or more prevalent?

How the fuck did they even control this study? Most people consume caffeine in one way or another. The one exception is Mormons, who actually have less disease than the typical population so this 💩 can seriously fuck off and stop wasting money.

Maybe 100% of the positive-caffine-outcome people also snorted 100mg of adderall every morning?

[–] SaveTheTuaHawk@lemmy.ca 1 points 2 days ago

Exactly. Stimulants improve test scores, which is why most students are on adderol one way or another.

Higher tea intake showed similar results, while decaffeinated coffee did not — suggesting that caffeine may be the active factor producing these neuroprotective results, though further research is needed to validate the responsible factors and mechanisms.

But why wasn’t this compared to caffiene from sources like energy drinks? Then even as a control why wasn’t other stimulants like adderal asked about?

Claiming it’s caffiene by comparing to decaf coffee is dubious to me personally because what kind of people drink decaf? Usually people who were long time coffee drinkers who had to stop for some reason

So is coffee and tea neuroprotective or is caffiene sensitivity a risk factor for dementia?

Is caffiene neuroprotective or is it all stimulants?

The article itself ends in the classic we need to investigate more but that’s clearly not the conclusion most people who discuss this are going to be talking about for the next few months
