Skip to comments.Lead linked to aging in older brains

Could it be that the "natural" mental decline that afflicts many older people is related to how much lead they absorbed decades before? That's the provocative idea emerging from some recent studies, part of a broader area of new research that suggests some pollutants can cause harm that shows up only years after someone is exposed.
The new work suggests long-ago lead exposure can make an aging person's brain work as if it's five years older than it really is. If that's verified by more research, it means that sharp cuts in environmental lead levels more than 20 years ago didn't stop its widespread effects.
... in recent years, scientists are coming to appreciate that exposure to other pollutants in early life also may promote disease much later on.
The big reason for the drop: the phasing out of lead in gasoline from 1976 to 1991. Because of that and accompanying measures, the average lead level in the blood of American adults fell 30 percent by 1980 and about 80 percent by 1990.
But work by Schwartz and Dr. Howard Hu of the University of Michigan suggests that the long-term effects of the high-lead era are still being felt. In 2006, Schwartz and his colleagues published a study of about 1,000 Baltimore residents. They were ages 50 to 70, old enough to have absorbed plenty of lead before it disappeared from gasoline. They probably got their peak doses in the 1960s and 1970s, Schwartz said, mostly by inhaling air pollution from vehicle exhaust and from other sources in the environment.

I wonder how those of us who grew up in more remote 'burbs fare compared to those who grew up along freeways or in densely populated areas.
I smell a huge class action lawsuit against the evil oil companies sometime in the future.
I was born in ‘64, I’m doomed.
I soldered all kinds of things together since I was about 8... Lots of smoke inhaled... Oh well...
I think that older brains have aged more than younger brains.
I just bid on a nice Lyman 429244 mould on eBay.
I was just thinking the same thing! May have to sell my reloading equipment.
All I know for sure, is that I couldn’t get the lead out of my arse and was a pretty slow runner.
Now it appears that I may be "Too Old to Get the Lead Out".
By the way, if you possess the Buck Owens rendition of that song, call HAZMAT and they'll know what to do.
I once heard an old gapper say, “I may be too old to cut the mustard, but I can still lick the jar.”

Depends on what he's cutting it with...a knife, or (recommended) some Jack Daniels.
It makes a great flavored mustard, but it's way too easy to overdo it. Just enough to get that neat flavor in the mustard, but not enough to make it too obvious.
If you get too much "Jack" in there, just thin it out with more mustard until you have the taste "tuned" the way you like it.
That is an interesting theory. I hope you receive enough Federal grant money to continue your research. :)
