I received the report from the Autism Spectrum Disorders (ASD) evaluation. It listed 9 recommendations, including genetic testing for atypical William syndrome (no MR and no heart issues as far as we know). I talked to the pediatrician today and she said that she only knew of one geneticist in our area and the waiting list is about 10 months. It will likely cost several thousands of dollars depending on the tests recommended. husband thinks it's a waste but will not go against it if I wish to proceed. I'm very conflicted, because V IS atypical. I can see why the PH.D doctor thought of William syndrome: the paradoxe of a cocktail personality combined with big social defficits. With grown ups, V is an absolute delight (was even put on the report!). But yet, he has difficulty with theory of mind. The internet mentions the very striking "stare" that babies with William syndrom have. That was V: he would stare at you in the eyes and it felt like he was trying to read your soul. Anyone who knew him as a baby remembers it vividly. Ultimately, I'd like to know. But is it reasonable to spend so much just to know? Wouldn't be cheaper to just see a heart doctor and make sure there are no uncovered issues? Does it matter wether we call it atypical Autism Spectrum Disorders (ASD) (read: Pervasive Developmental Disorder (PDD)-not otherwise specified) or atypical William syndrome? At the end: V is atypical and probably the reason all the specialist are puzzled by him and sometime struggle to help him. At school, he is not learning like the other kiddos and the teacher already mentioned holding him back or, more precisely said "V will not be held back just because of reading problems". Meaning that reading issues don't warrant holding a child back, there needs to be more issues. So yes, she was trying to be positive, but all I keep out of it: the teacher is already thinking that V might need to be held back. She is very positive about his work and never forgets about his numerous challenges, but bottom line: he is not learning as fast as his peers. So how does it help to call it Autism Spectrum Disorders (ASD) or William syndrome? Either way, V is not behind enough to qualify for an IEP. Either way, his therapist are working on his lacking skills and building on his strenghts. Yep: I'm confused!
