Yesss LadyBug... there is definitely an "Autistic spectrum" out there, and it may even be the type of range that may be difficult to be represented by a typical 2D image like a pictogram and may have to be extracted into the 3D dimension or something. Each person is a unique individual, and "Asperger's" for me is a placeholder term ATM until they come up with some other way to calculate this like they can BMI for physical health -- that is, if they ever can! We'll see where science gets us. But in the meantime,
I don't see how anyone could be accurately diagnosed on a cold, clinical basis alone -- for me, you really have to get to know someone over the years, especially in the cases of diagnosing people who are way past adolescence, and look back towards youth for clues and see how it all manifests in the present.
I don't want to compare it to a drawn-out courtroom case, but really, the evidence must be weighed over an extensive span of time. Most of the diagnostic criteria for Asperger's, when presented alone, can be linked to other conditions as I'm sure you're aware , but when you have a whole bunch o' them and have acted this way throughout time and space, there's definitely something going on there and it's how I have found out things about myself. I got the "little professor" anecdotes from my teachers. I have the hyperfocus. I don't have serious eye contact problems, but body language misinterpretation, yes (old friend just told me I sure did cross my arms a lot, even when I wasn't defensive). And for example, I don't really have the nervous tics and shaking anymore, but that's because I was able to use my willpower to stop the majority of them over a span of a decade. But I did have that, as well as the lack of common sense, and the whole ALIEN FEELING!! ! MWA HA HA... *laughs*
