Amy,
The boys could fit some of the Pervasive Developmental Disorder (PDD)-not otherwise specified criteria, minus the speech delay, and still have Pervasive Developmental Disorder (PDD)-not otherwise specified. I do not think every chilc with Pervasive Developmental Disorder (PDD)-not otherwise specified has a speech delay. That is what makes it so confusing, because it's a spectrum and so many kids are so different.
I think, at this point, your best bet is, again, going to be to keep a journal for each boy. I think you should do some more reading on Asbergers and Pervasive Developmental Disorder (PDD). If they both tested mild for Pervasive Developmental Disorder (PDD)-not otherwise specified, I don't think you should discount that only because neither had a speech delay.
The confusing words thing could be something like an Learning Disability (LD), too, and nothing to do with Autism.
Have you looked for a neuropsychologist yet?
