High rates of autism are linked to high levels of parent education, not neighborhood toxins, in Silicon Valley and nine other regions of California, conclude University of California-Davis researchers.
College-educated parents of autistic children are more likely to fight for a diagnosis — and seek the state-funded services that accompany it — than less-educated parents, according to the team. Parents of children in these autistic “clusters” are also more likely to be older and white.
Researchers did not see more autism in the Silicon Valley than in Sacramento or Southern California, suggesting there is no “geek gene” that predisposes techies’ children to autism.
The high-autism areas did not share the same toxins.
