Done. I wouldn't go as far as calling it a "swipe or nasty trope". The guideline just says to avoid this type of insinuations.

"Doesn't slow down mental decline"... They're not suggesting anything. They are summarizing the conclusion of the study which determined that intellectual engagement may not offset age related cognitive decline.

Wow, a rate of drop-out like that would certainly make me doubtful of the results of the study. It seems reasonably likely that people dropped-out in a fashion that would be weighted in one way or another.
for sure.. but I expect the real results to be worse (though this is purely speculative on my part), as I can only imagine people with steeper intellectual decline being more likely to drop out
Seems to me that even if it didn't slow down the "rate" of mental decline, starting from a higher point because of "brain training" for want of a better term would still be good, no?
But exercise does: https://www.news-medical.net/news/20160324/Exercise-slows-do...
In this study, they detect a correlation between exercise and mental ability, but it is not clear which one is the cause and which one is the effect. Perhaps people with very advanced mental decline can't follow any class of exercise. >> Our results suggest that moderate to intense exercise may help older people delay aging of the brain, but more research from randomized clinical trials comparing exercise programs to…

This is a fascinating share, if not for the results—"None of the measures of intellectual engagement was linked to the speed of decline of people's mental abilities over time"—but for the study itself. "Many people also dropped out of the study. Only 96 of the 498 people recruited took part in the last round of testing. The researchers lost touch with 13 people, while 57 people died and 332 declined to take part." Do…
This is one of the major downsides to longitudinal studies— people are unpredictable.

I immediately thought the same. Then I thought about for a bit longer and quickly came up with an equal number of reasons why participants experiencing more rapid mental decline might stick it out. Really no way to know.
