U.S. plans controversial autism study

Wednesday, July 9, 2008


The government wants to test chelation, a treatment for lead poisoning, on children with autism -- even though there's no evidence it leads to improvements.


Proof that chelation doesn't work might dissuade many parents from trying it, the government theorizes. Other scientists decry it as quack medicine.


Chelation treatment can involve pills, suppositories or IV treatment. Side effects can include rashes, low white blood cells and vomiting. Also, three deaths have been linked to medication errors involving the IV treatment.
