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.

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