A new study has found a significant factor in the development of Autism among children.

FOX News Radio's Chris Stanley reports:

A scientist with the Autism Center at the University of California San Diego says that for years, a big puzzle has been looking for evidence that Autism begins in the womb.  Now, Dr. Eric Courchesne says, "we have something really solid."  Courchesne's team has discovered that autistic children appear to have too many cells in a key area of the brain needed for communications and emotional development, the prefrontal cortex, and that those cells develop during the second trimester of pregnancy.  He says this helps explain why these children often develop brains that are larger than normal, with a quote "potential for mis-wiring which would lead to abnormal function."
