Why do they show a picture of polluted India with people wearing masks and have some kind of skin thing going on, and then go on to show a heat map of PM2.5 rates across the USA, where the most polluted areas are nowhere near as polluted as non-western cities/countries [1].

Why do we never talk about the fact that the post polluted areas are not at all in the European civilization block, i.e., they are Bangladesh, Pakistan, India, Chad, and the DR of Congo. So they should also have the highest rates of dementia if this research holds, right?

This all just seems like gaslighting lies, manipulation, and abuse.

Who is to say they don't? Most of those areas have a less developed health infrastructure, so I'd expect the statistics on dementia diagnoses to systemically underreport the issue.

The average age in developing countries is also lower (due to both lower life expectancy and higher birth rate) which is a further confounding value to skew the numbers. Dementia is an old people game, even if it is true that air pollution worsens it.
