For a while, scientists assumed there was a link between lead exposure and adult deficit hyperactivity disorder.
Now, Oregon Health and Science University says it’s been able to confirm that link.
Children inherit a propensity for ADHD from their parents, but there’s also considerable evidence it can be triggered, or made worse by environmental factors — like lead.
By looking at the genetics of almost 400 children, OHSU professor Joel Nigg says that they’ve been able to scientifically confirm a lead and ADHD link.
“This means that it’s not just a genetic condition," said Nigg.
"We have to take these environments very seriously. And if we do, we can get a handle on the cause," Nigg said. "We can learn how to prevent ADHD.”
Kids pick up lead from old water pipes, smoke-stack emissions and dust generated by lead paint — like on an old window frame.
And in some Northwest communities, lead and arsenic have turned up in high quantities in soil where orchards used to exist.
