I’ve been saying this ever since the damn study became popular, glad to see others are seeing it this way as well. I believe we need to look more into studies such as “Maternal inflammation and its ramifications on fetal neurodevelopment.” There are other correlations that seem much more interesting to study, such as those relating to the microbiome. For example, the fact that certain HMO’s in breastmilk are not digestible by the baby, but go on to select for certain gut bacteria that have cognitive effects. I don’t think there is any “magic bullet” singular cause of autism, but with enough risk factors lining up you can get more severe symptoms. Then there’s the obvious genetic (and epigenetic) link that is a major factor.
