Air pollution directly linked to increased dementia risk

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.

The countries you give all have less than half and usually less than a third the percentage of people over 65.

That is simply not a good argument. Any number of things could even explain that is it were true, starting with the most basic and obvious math problem; the fact that their reproductive rates are way higher so any percentage of older people will invariably be far lower.

Have you ever asked yourself why you make such irrational excuses?
