It seems to me that perhaps the data better supports that dementia is correlated with unintentional and short naps. This makes it sound like they think it is causal, which I doubt.
Yes, ironically they even admit possible reverse causal effect along with many other causal variables. Frankly, this is not exactly stellar research in my view, at least with the rather reckless insinuations not supported.
drive-by comment: unintentional napping seems likely to occur more in those failing to get actual restful sleep on the regular. Don't we already know chronic sleep deprivation correlates with dementia/alzheimers risk?
Unintentional napping was associated with possible/probable dementia.
Intentional napping was not.
One could easily reverse cause and effect here.
Yeah I feel like the results could be stated more clearly. At any rate this doesn't seem to associate risk with any chosen behavior.

Easily. I'm 80% sure that they did reverse cause and effect.

"unintentional napping"
I used to 'unintentionally nap' all the time since I was a teen.
Then I discovered I had sleep apnea. No more napping. And dementia has been linked to sleep apnea.
I wonder if this study is missing some quite big issues here.
I am a frequent intentional napper (< 30 minutes). Am I right in reading that I am at baseline risk?
I think we need to understand what intentional vs unintentional napping is.
Is this not clear from the term?
"I'm going to go take a nap in bed."
vs
"I fell asleep in a chair."
No, we need to know how the study defined them, not how you interpret them.
In medicine, sometimes semantics are more important than you think.
Yet I intentionally nap in the chair when I become overcome with lassitude
Where do you nap when overcome with langour or ennui?
See what I mean?
I'd guess this goes back to not getting enough healthy sleep, which is a reason people nap.
Except intentional napping, which could be "yawn, I slept bad last night; I'm gonna go take a nap" is not a risk.
Sleep apnea.
