Study of Chelation to Treat Autism has been Suspended

Posted on Aug 1, 2008 in Autism, Heavy Metals

The National Institutes of Health has canceled the clinical trial intended to examine whether DMSA, an oral chelating agent that removes mercury and other metals from the body, can help children with autism.

Critics of the study have noted that no credible evidence exists that autism has a toxic basis or that autistic children harbor abnormal heavy metal levels. The cancellation was triggered by a study which found that rodents with normal lead levels suffered neurological damage after DMSA was administered.
