Autism : One in Four Mothers of Autistic Children Have Antibodies That Target Fetal Brains

  University of California, Davis researchers have found maternal antibodies to seven fetal brain antigens in nearly one quarter of mothers with autistic children. This finding could lead to a maternal blood test to identify children at risk for autism spectrum disorder long before symptoms manifest. This finding may herald a potential treatment option to prevent autism by blocking exposure to these antibodies in children born to affected mothers.

  In a second study, also from UC Davis, IgG from mothers of children with autism was given to pregnant rhesus monkeys the offspring of which displayed inappropriate social interactions.
