Autism, Asperger, ADD, are simply terms to define different wiring types. Neuro chemistry, physiology, and neuro nets perceived by experience. The multitude of factors makes it near impossible to categorize. Once you have seen on autist you have seen simply one unique autist version. To make blanket definitive statements regarding brain types should always be considered theory. (The ultimate quantum computer.) Based on placebo impact it is clear what an individual believes / intends will manifest. Every thought matters. Thought will always "preseed" the experience.
Baked noodles anyone?
