Yikes, this is good to know...
The study, conducted at the Australian Centre for Precision Health at the South Australian Health and Medical Research Institute, is the largest of its kind based on 17,702 participants aged 30 to 37. Kitty Pham, a PhD candidate at the University of South Australia, who led the team of international researchers, says the findings draw attention to the risk of over-consuming.
Coffee is among the most popular drinks in the world. Yet with global consumption being more than nine billion kilograms a year, its critical that we understand any potential health implications, she explains in a statement. This is the most extensive investigation into the connections between coffee, brain volume measurements, the risks of dementia, and the risks of stroke its also the largest study to consider volumetric brain imaging data and a wide range of confounding factors.
Accounting for all possible permutations, we consistently found that higher coffee consumption was significantly associated with reduced brain volume, she continues. Essentially, drinking more than six cups of coffee a day may be putting you at risk of brain diseases such as dementia and stroke.
Drink water alongside that cup of coffee, researchers suggest.
The findings are published in the journal Nutritional Neuroscience.

(33,140 posts)My Mom succumbed to a form of dementia and looking back on her last decades, I'm sure she knew it was happening and was compensating (very well, IMO). She also upped her caffeine in those years.
Someone who's mind is fading for other physical reasons might drink more coffee to maintain their focus.

Are six Mountain Dews a day just as bad?
Retrospective studies, such as this, can "suggest" correlations but are not able to prove them.

Also, being dose dependent, does the brain shrink half as much if 3 cups are consumed? Yikes.

(34,069 posts)The final line uttered by someone connected with the study buys into the bad science that liquid is not liquid.
If it were true that drinking coffee dehydrates you, all of us coffee drinkers would be withered old prunes. Trust me. We're not.
Drinking caffeine-containing beverages as part of a normal lifestyle doesn't cause fluid loss in excess of the volume ingested. While caffeinated drinks may have a mild diuretic effect meaning that they may cause the need to urinate they don't appear to increase the risk of dehydration.

(17,175 posts)On the plus side, according to my study, a distilled coffee enhancer (like Irish Whiskey, or if you like your coffee lighter, Bailey's Irish Cream) will counteract the negative effects. And even if it doesn't, after four or five cups, who cares?

So says this old mariner.
Nay
(12,051 posts)it the "coffee carafe cup," which is 4 or 5 oz.? Or is it the standard mug size cup, which is 12 to 14 oz.? Report your measurements, scientists!! Surely if you have decided that "6 or more cups" is bad for you, you must have at least measured the size of people's daily cups, or measured the liquid ozs. drunk by the test subjects during the study period, etc.?
If they are claiming that six or more 4-oz. cups of coffee is bad, then the person who drinks two 12-oz. mugs is in the same amount of danger, but those mug users will never know the danger they're in, because they only drink TWO cups of coffee a day.
Maddening.

(2,120 posts)How big is their "cup"? How about they specify fluid ounces per day instead, or at least give an equivalency.
And I wonder how that relates to body mass? And how "strong" is the coffee? There are different roasts and strengths.
Sounds like sloppy science to me.

I read that the researchers did not conclude the exact mechanism causing the dementia.
