Are cpaps that widely used to have that significant of an effect?
For CPAP to be primarily responsible, we would need a very sizeable portion of the population to be using them, but I think the numbers are less than 3% right?
From the article as to the effect size:
“For example, in the US, among people aged 81 to 85, 25.1% of those born between 1890–1913 had dementia, compared to 15.5% of those born between 1939–1943,”
I'm not saying that CPAPs don't contribute, but they are not likely the main contributors.
- alargemoose 1y agoI think you have this backwards. OP is saying sleep apnea is common, but we’ve only had CPAP machines to compensate for it, since the 80s. I don’t see them trying to implicate CPAP as the cause of an increase in dementia.
- sokoloff 1y agoI read that as saying that 3% CPAP usage couldn’t explain a 10% drop in dementia.
- Someone 1y agoI think bhouston is arguing (correctly) you can’t have a 10% of the population drop in dementia prevalence by an intervention that only targets 3% of the population, so even if CPAPs contribute, that does not explain most of the drop. (If everybody who uses CPAPs would get dementia, and they are 100% effective at preventing that, the drop would still be ‘only’ 3% of the population)
