Ds (almost 7) has PDA with no significant overlap with ASD. wWe know its PDA cos he conforms entirely to the criteria, responds well to PDA strategies/awfully to trad techniques (when dd aged 9 responds appropriately. We are trying to get an appropriate diagnosis.
We have already seen the comm paed 3 times and the ed psych has assessed. Between them, they have decided characteristics do not indicate asd so refer to camhs.
So, given that they've pretty much discounted asd and no one seems to have heard of PDA I am worrying that we will be interviewed to see how exactly we have messed up ds to make him behave like this. It will take forever to eliminate all the other possible causes this way, how can we avoid going down this route?
