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.
One in 88 children in the US have autism (CDC).
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.
