I have alot of things speeding around in my head. Emmy also has a very hard time communicating. I often have to decode. Like “me do” = I need help.My pointing (tummy or eyes)hurts.= I’m hungary or tired. I don’t think untreated PKU can lead to austim. Now untreated PKU can lead to mental retardation. Two different things. Austim can be treated with alot of therphy while mental retardation can’t. Some austic people are very smart.Dr. Temple Gradin is austic, She sets up feedlots for different companies, one of them being McDonalds. She teachs and heads the Animal Science Department at Colorado State University.
