hmmm...
prometheus, even though you were joking, you may well be interested in part of my thesis (which i'm trying to write up into an academic paper) about the congruence between characteristics of the image of the witch, and characteristics of someone with AS. the degree of congruence is scary.
one bit which got me was that an awkward gait (an oft-mentioned characteristic of AS) was a sign of a connection with the Underworld/otherworld. (it's in Carlo Ginzburg's "Ecstasies", if you want the reference).
