Was this confirmed somewhere? I can't find any evidence with a quick search and I saw some of his interviews during the presidential campaign (he was running from the libertarian nomination I think) and he seemed ok.
I think a lot of that stems from his reported behavior in Belize. I think it was reported he was high on something on the occasions of some of his reportedly bizarre behavior. From my recollection.
Most probably they did throw in fact it around lightly, but (carelessly) didn't intend to. I'm always very careful to not throw around medical (particularly psychiatric) diagnoses because I'm not trained for that. Instead I prefer to describe the symptoms I perceive and phrase it as my personal perception (aka, own it). At very most I might say "that guy might have some autistic tendencies ..." and almost always qualify it with "... but that spectrum is so vague, forget the label and just assess him on his particular quirks like the individual he is".
Anyway, not to distract this discussion into a further tangent, I think the best way is to charitably read it as "paranoid schizophrenic episode" (which is kind of fair, yes?) and the "mind AWOL" remark as hyperbole, without reading too much behind it. It was a setup to the post's main point anyway, the anecdotal part.
