That is the background. Over the weekend, I got a chance to observe, up close, his progress. He's now into art, marine biology, and chess, pretty good for a 10-year-old. He seems happier, and more willing to at least engage people one on one. He's also getting better at faking body language.
I think he's going to be much happier with his life- which makes me wonder what would have happened with my life had I been able to access this training and this diet when I was young (not that Asperger's was even considered as a diagnosis for me before 2000, and I would have needed the treatment in the 1970s to avoid warping my growing brain).
