Outstanding article! In my book Beyond Mental Illness I discuss Patterson’s work. He found that MIA predisposes to gut permeability, microbiome DNA alterations and autistic-like behaviors in rat offspring.
He “treated” the “disturbed” rats with B fragilis to reduce gut permeability and these rats showed improvements in behavior. In addition, the alterations in the DNA were themselves altered. I also raised the issue of vaccinating pregnant women.
I am surprised no one has done a human study of this yet.
