Scientists at the University of California, San Diego Autism Center of Excellence has found a new study about autism. They have discovered that autistic children have many more brain cells than their typical developing peers. This was discovered when the babies were still in their mothers' wombs.
"Autism affects one in every 150 children in the U.S., and a new study by UC San Diego scientists indicate the roots may be found in prenatal development.
It also suggests that the bulk of autism's effect on the brain is felt early on, in the prenatal and perinatal stages of development, and not caused by environmental factors in infancy."
