As expected they did not diagnose clinical dementia so the findings are highly debatable. More people need to look at actual metrics used instead of the clickbaity headlines. Also if you want to imply any kind of causation the study needs to be much longer. Here they started the study after people were in their 70s which is fairly late already and you are much more likely to have bias or random people having cognition decline no matter what.
