That would be an interesting research question. Although, I am not sure that they would like different neurologically? Maybe, maybe not. I have been thinking a lot about that distinction lately. It seems that some see them as different things, but others think that our use of the overexcitabilities concept just obscures real conditions like SPD, ADHD, etc.

I am not sure what I think about that yet. I know that when I read about overexcitabilities I had a major "aha!" moment about my ds. SPD also fits, though. So I don't know. Is it overexcitabilities? Or does he really have SPD? Are over excitabilities "real"? Does it even matter what we call it as long as the issues are being addressed? These are the questions I have. I am really glad there are researchers taking SPD seriously, though.
