I don't understand how you can be unable to visualize scenes in your head but also write a script for _Silicon Valley_ that contains descriptions of visual humor.
I'm really skeptical of this "disorder." I think it mostly amounts to "semantics and variability in human abilities, not pathology."[1]
Metacognition like this is super slippery and is really easy to draw whatever conclusion you want. I've just never been able to draw even mildly realistic anything ever, this doesn't mean I have a disease.

Sure, we can call that a "variability in human ability" rather than a "disorder". I never used the word "disorder" anyway.
And, I mean, you _did_ couch this as a disorder when you made the single-subject case study your proof.
