Personally what used to be "high-functioning" Autism and Asperger's are the same in my manifestation of ASD. I predominantly appear to be what was known as Asperger's, but under significant duress I very much appear as classic Autism. Likewise, I expect someone with "classic" Autism with development and/or support would appear as "Aspergers". I have Asperger-like friends who have not had significant duress in their lives so haven't observed how they would behave in those times --- they get to think that Asperger's and classic Autism are more separate than they are. My point is Asperger's folks may be able to "handle" more stress but really the underlying characteristics and responses are similar --- a spectrum. Coming from me this is odd b/c I put myself in a lot of stressful situations, but as a sensation seeker... ah, well. Like I said, most of my friends (have been able to) avoid stress so they are more "comfortable". The speech delay thing is weird: my daughter had a speech delay from my perspective, but was never in speech therapy. Now at 10 she doesn't like to talk, but she does. Her teachers consider her to be a typical student, albeit quiet. Thus she would be considered the Asperger type --- "passing" in mainstream activities, e.g. she rubs her hands vigorously under her desk and -for now- teachers and peers aren't taking note. Wishing you well in your self-exploration!!
