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
