For those who lived through this first wave of lead neuropathology, there could be a second round as they age and then experience the delayed effects of lead on neurodegeneration.

It is, thus, probably a significant advantage for those who are now in their mid-60s, 70s and over instead of those in their 30s, 40s and 50s in terms of AD risk because ambient lead levels maxed out in the mid-1970s and those who are somewhat older will have avoided peak lead during critical periods of their brain development.
Hi J11, Seems to me that we still have plenty of social dysfunction!
Though ambient levels have gone down with the phasing out of leaded gasoline and the outlawing of residential house point with lead,
there are still abundant "opportunities" for exposure. Many municipal water systems contaminate the water they deliver with lead pipes. And millions of older homes still have lead paint.
But isn't attributing social ills to lead neurotoxicity, as if it were the primariy factor, an over-simplification of complex problems? It may well be a factor, but to say it "caused an enormous social crisis in America"...?

Flora, thank you for replying. Yes, that is the interesting thing people will typically watch the news cycle and see all the bad news and form the impression that things are worse than ever. We have hit a new all time low! One new time low after another.

It's only when you start searching through the statistical evidence that you realize things aren't so bad; in fact things aren't even that bad but in fact fairly good.

Consider this result for school violence. there has been over a ten fold reduction in typical type school violence and bullying over the last ~20 years? That's quite good news. As I have looked around I have found a great deal more of such evidence. From my current understanding most of this good news relates back to lowered lead levels.
