She does. The stimming is very autistic-style, for one thing. She never makes eye contact. She doesn't have back-and-forth conversations; just answers questions. Her tone of voice and inflection seem quite typical, though. At seven, it seems like it's difficult to tell whether she's having true hallucinations or whether she's having trouble interpreting the world, period... It's as though she can't figure out whether her thoughts are coming from her own mind or not. The hyperactivity/shutdown thing looks like she's trying to keep herself engaged, then shutting down when she can't manage it.
The biggest thing I noticed, though, is that she is not happy about being interviewed, and she's not afraid to avoid it. Repeatedly she says she doesn't want to talk. I think she knows very well that Oprah's trying to make a spectacle of her. Trying, for that matter, to make a spectacle of the fact that she doesn't want to talk to Oprah, because obviously this is Not a Normal Thing. Later on she says "I know that was the disease"... No. I don't think it was. I think she didn't want to talk, and I don't blame her.
Really, she seems to me to be simply a little girl who has trouble with managing her own activity level and figuring out her world. She's just this little girl, and everybody else is talking about what a tragedy, what a burden, etc. I just hope she never picks up on that, though I guess she probably already has.
We used to have freak shows. Now we have Oprah.
