Psychotic disorders like ASD's have in common, the work on low latent inhibition. That means, their brains are particularly bad at screening out "unnecessary" things. Sometimes not having the same filters as others can prove interesting and productive though.

So yea, there is a similarity. Also, no one is a textbook example. No one fits into a diagnosis to 100 %, so it is quite possible both having traits from psychosis and Asperger's.

A diagnosis like schizotypal is an example where they have tried to merge mild psychotic symptoms with a autism like base.
