Hi all! Just wondering if anyone knows anything about this. I have read that they can tell children are ADD, by looking at scans(Petscans/MRIs). Can they tell if children have Autism in this way? Does anyone know of any hospital or university doing these types of studies currently? This topic just came up in a discussion recently and I was thinking maybe I'd ask it here to see if anyone knows. If you have had this testing done, I'd love to also hear about it.
