Mom’s dental amalgams may trigger child’s autism

… Mercury found in dental amalgams has also been singled out as a culprit in the onset of ASD in children. A 2009 study published in Acta Neurobiologiae Experimentalis found that children born to mothers with six or more mercury-containing dental fillings were more than three times as likely to develop autism.

“Furthermore, the risk of increasing autism severity became significantly manifest among those study subjects with six or more maternal dental amalgams during pregnancy in comparison to those study subjects with five or fewer maternal dental amalgams during pregnancy,” researchers said.

Another study found that mothers of children with autism were more likely to have dental amalgam restorations than those of healthier children. The results suggest that “…high Hg [mercury] levels in children with ASD may relate to the increased exposure to Hg from maternal dental amalgam during pregnancy and lactation,” researchers noted. Data also showed that children with ASD exhibited higher levels of mercury toxicity than their healthier siblings and peers. Subsequently, children with the highest levels of mercury exposure displayed the most severe symptoms of autism.

Researchers at the Arizona State University found that children with autism had higher levels of heavy metals in their bloodstream compared with their healthier peers. Study data, published in the journal Biological Trace Elements Research, showed that children with ASD had 74 percent higher urinary lead levels, 77 percent higher thallium levels and 115 percent higher tin levels compared with the controls.
