My DD (18) is being assessed for autism via an NHS service. At the initial screening they had loads of questions about school age 4-5. Basically she had no problems really until around age 14. Beyond some slightly strange/eccentric obsessions (and they weren't really out of the ordinary), she coped well, did well, made and kept a small good group of friends. After that age, however, it seems to me that she ticks all the boxes, and in the last couple of years lots of things have fallen apart for her, basically. I know that girls are harder to diagnose, but surely all the professionals know that too, and would take that into account? My questions is, if she doesn't meet the critieria for autism, what else could it be? Would she simply be not autistic enough to meet the critieria? Or without early development problems is it not possible for her to have autism?
