The study doesn't claim a direction for the causality- it merely points out the correlation.
The study briefly admits that, but then they go out of their way and use language that for most people reading it would have the opposite meaning: "For the first generation that was exposed to digital tools, their use is associated with better cognitive functioning" and "This is a more hopeful message than one might expect given concerns about brain rot, brain drain, and digital dementia" and "they found that using a computer, smartphone, the internet or some combination of these was associated with a lower risk of cognitive impairment"
The problem is, none of these statements are true. They did not check groups that have never used smartphones against group that have. They only proved some correlation that is pretty obviously not causation. Claiming "lower risk" is flawed. FWIW, instinctively I am not a fan of the digital dementia hypothesis, but this meta-analysis claims to prove things that it doesn't.
