Does this imply that in 30 years or more we should expect spikes in China, India and other places with exceptional air pollution?

I don't doubt it and they could expect other implications if the pollution also included heavy metals and other chemicals in the air, water and land.

The air pollution in China and India was already awful 30 years ago, so "spike" is not be best choice of word. "Continuation of a high level of dementia" would be better.

I guess it would be a large and massive upswell in the coming decades because dementia isa trailing indicator and takes decades to have effect on populations. China only started pumping out massive amounts of dirty pollution in the mid 90's and China probably in the 2010s or so, so the impact is yet to hit them but if the conclusions are correct then wow...

I remember reports of terrible air pollution in China in the 1990s. China is burning much more coal now than it did then, and has about a thousand times more cars, but since the 1990s they've also instituted controls on how much air pollution a car or a unit of coal produces.
