Lack of communication really, really does not unequivocally imply lack of higher cognitive function,
Just to be clear, I was definitely not saying this. But given how central social ties are to human happiness, correcting the lack of ability to communicate, irrespective of other cognitive function, is presumably the primary focus of the "cure."
To what extent should the word "neurotypical" be inserted after "to" and before "human"?
Also, "irrespective" is perhaps an infelicitous choice of words. Or maybe all too appropriate, depending.
I ran across this article that I think is interesting. It suggests that type 2 diabetes and the increase in autism may have a common link
