Which kind of autism/mental disorder do you find most interesting to read about?

Personally, I find schizophrenia to be pretty interesting, but I especially find [url=http://www.mayoclinic.org/diseases-conditions/paranoid-schizophrenia/basics/definition/con-20029040]paranoid schizophrenics[/url] to be really interesting to read about. It's basically when a person sees and hears imaginary people or objects, but they lead the victim to believe that the government is out to get them. Often times the victim is afraid that the government is reading their minds so they may wear (literally) tin foil hats or they might swipe their hands around their heads every so often to scramble the government signal. It's just odd how common this kind of schizophrenia is that it has its own diagnosis. Anyway, what mental disorder do you find the most interesting to read about and why?
