On a recent Dateline, they reported on a professor of chemistry, Jim Adams, who has a daughter, Kim with autism. Jim is beginning a study regarding the mercury levels of children with autism, whether or not this seems to contribute to their condition and if Chelation therapy can help. Chelation is a controversial therapy to lower mercury levels in the body. Controversial because there are parents who swear that Chelation cured their child but recently a child died who was being treated with the therapy. There are scientists on both sides of the debate. Jim Adams has not made up his mind. Chelation did not help his daughter, but he feels that a proper study is necessary to settle the debate. Go here to see the transcript.
