We've heard a lot about the recalls for the toys made with lead paint. Lead poisoning can have severe impacts on a child and his or her family.

Problems for Noah Breakiron began at nine-months-old. He was often sick and out of control.

"We couldn't go to the grocery store, church, really anywhere due to the screaming," said Rob, Noah's dad.

Noah was diagnosed with autism, but then the underlying problem was discovered: lead poisoning. Noah had seven-times the upper limit of lead in his body.

"We were shocked," said Lisa Breakiron, Noah's mother. "We were absolutely shocked. Like, lead poisoning? That can't be right."

Lisa and Rob couldn't pinpoint how the lead got in Noah's body. But now, his parents believe it might have been from his toys.

"I can tell you when he was a toddler, he was always chewing on stuff," said Rob.

Chealation treatments have reduced Noah's lead levels and have made a huge impact.

"It was really powerful and amazing for us to watch. It was like literally watching a miracle right in front of your eyes," said Rob.

Pediatrician David Berger is Noah's doctor.

"We have a child here who is virtually indistinguishable from his peers and that's certainly not what he was a year or two years ago," said Dr. Berger.

Dr. Berger says a developing brain is much more sensitive to lead exposure. He says universal testing for lead in young kids should be done. It's a blood test doctors stopped doing routinely ten years ago, but one he says parents should ask for.

"This can cause significant long term problems and it's worthwhile checking for," said Dr. Berger.

"With Noah's level of lead poisoning, if that would have continued, he could have died," said Lisa.

Today, you can't tell that Noah's body is in a battle to remove the lead. He just seems like a typical four year old, and that's good news. Because the symptoms of autism and lead poisoning mimic each other, Noah's parents say they will never know which came first, autism or lead poisoning.
