New research suggests analysis of zinc and copper levels in baby teeth could help predict the developmental disorder known as autism.
Key takeaways:
– As each new layer is formed on teeth they contain records of chemicals exposed to.
– Significant differences found in levels of zinc and copper in teeth when comparing children with autism and those without autism.
– Could lead to prenatal markers for an earlier diagnosis of autism from the records from children’s dentist.
“This study is the first to find a marker that can predict the risk for autism with 90 percent accuracy, the research team said, and may point to a possible new way of diagnosing autism.”
