Unintentional napping was associated with possible/probable dementia.<p>Intentional napping was not.<p>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.
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.
Easily. I'm 80% sure that they did reverse cause and effect.
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.
"unintentional napping"<p>I used to 'unintentionally nap' all the time since I was a teen.<p>Then I discovered I had sleep apnea. No more napping. And dementia has been linked to sleep apnea.<p>I wonder if this study is missing some quite big issues here.
> I wonder if this study is missing some quite big issues here.<p>Definitely seems like a possible "correlation is not causation".<p>I would find it hard to believe that sleep is somehow biologically harmful.<p>So, like your example, excessive or unintentionally napping is instead a <i>sign</i> of an underlying issue or poor health. Possibly the body trying to sleep to repair some damage?
I feel like “unintentional napping” should not be called napping…<p>Napping for me means intentionally having a short sleep. I don’t know what unintentional napping is.
I am a frequent intentional napper (< 30 minutes). Am I right in reading that I am at baseline risk?
I'd guess this goes back to not getting enough healthy sleep, which is a reason people nap.
Sleep apnea.
disclaimer: I didn't read TFA<p>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?
