During the test period, they also participated in various memory and thinking tests, while researchers tracked and monitored their brain blood flows with several ultrasounds.

Um. There is a very well known correlation between using your brain and a lower risk of dementia. It is why the better nursing homes encourage residents to play games, do puzzles, crosswords or sudoku and interact with each other by singing, lecturing or general discussion. IIRC (possibly not) that gives a similar effect on the brain blood flow as the one being reported for cocoa.

Not that I'd discourage people from drinking cocoa - it is rather good. But this is a study with two variables, one of which is already known to be beneficial.

Um.  Your nit-picking about variables doesn't make sense.  The article clearly states they were subjected to thinking and memory TESTS. 

Thinking and memory TESTING is not the same as thinking and memory exercise and activity.  I worked in cognitive rehab for enough years to know the difference.

They were TESTED during the time they were drinking 2 cups of cocoa a day.

Yes, it would appear the memory testing was done to see whether the cocoa had an effect on their overall cognition. It wasn't that the participants necessarily already were keeping their minds actives with crossword puzzles and the like.

Fair enough.

Their methodology seemed flawed to me, so it was something to point out. I always take these "X is good for you/X is bad for you" studies that make it into the media with a huge pinch of salt (which is apparently good for me as a hypo-tension sufferer but will kill me in short order according to the health panels.)

Would you mind explaining the difference between tests (carrying out specific activities) and activity (carrying out activities). To me - and other laymen in the field of cognitive science - they'd seem to be pretty much the same.

Edit - that was for Lipstick on a Hillary. And no snark, I am curious about everything.  :laugh:

Same here, especially since the experts so often are unable to decide whether the same thing is good or bad, e.g., coffee, eggs, etc.
