This is a good question and one that needs clarification for sure.
Autism, Aspergers, and SPD are all different and distinct diagnoses. Although they are often similar and overlap, the bottom line is that you can have any one of these without having the other.
A huge percentage of kids with Autism also have SPD. A large percentage of kids with Aspergers also have SPD. But one does not have to have SPD to receive a diagnosis of Autism or Aspergers. And one does not have to have Autism or Aspergers to receive a diagnosis of SPD.
My favorite resource for identifying, understanding, and treating different diagnoses including the ones you mentioned is:
Just click on the book to find out more. I HIGHLY recommend it for anyone trying to sort out the different diagnoses that tend to overlap and co-exist with SPD (including auditory and visual processing disorders, dyslexia, dysgraphia, ADHD, etc.).
It surely can be confusing! Please comment below if you have further insights about Austism

Is SPD A Form Of Autism Or Aspergers?
I have also questioned this about my son who was diagnosed with SPD. He has some SPD traits that seem to overlap with Asperger's. I am anxious to get the book you recommend to help give some clarity to this issue.
