As far as I know, bipolar manic/depressive is a mood disorder, where as Asperger’s is cognitive.
Bipolar is characterized by wild mood swings, where as Asperger’s has nothing to do with mood, Asperger’s can be moody, or not.
Asperger’s is characterized by lack of cognitive empathy and coordination, but are sometimes-often good system builders, where as bipolar has little-nothing to do with cognition.
I don’t think they’re especially comparable, nor contrastable.
Asperger’s and schizophrenia are both cognitive disorders, thou schizophrenia can affect mood also, especially schizoaffective, which’s kind of like bipolar and schizophrenia combined, their neuotypical when depressed, and neuroatypical or crazy when manic, what a trip eh?
Asperger’s lack communication and people skills and sometimes schizophrenics do too, but in different ways.
What makes them good to juxtapose in my mind, is Asperger’s are mathematical, scientific, fact oriented, and are attracted to order, predictability and regularity, their speech is very concrete, dry, literal, straightforward, where as schizophrenics are intuitive, religious/spiritual, fiction oriented, and are disorderly and erratic, in thinking, speech and often behavior, they’re attracted to dark, esoteric, mystical subjects, and are holistic, poetic and whimsical in thinking and speech.
Both of them tend to be introverted loners, having difficulty expressing themselves, with fitting in, but for very different reasons.
I’m not sure if schizophrenics are better or worse with coordination and empathy, it doesn’t seem to be about that, but in terms of their thought and speech patterns, they seem opposites in many ways.
Asperger’s would have trouble forming an opinion on what other people are thinking or feeling, where as schizophrenics might project thoughts, feelings and intentions onto others from their own imagination that aren’t there.
You could say asperger’s are like mental tortoises, conservatives, attracted to the simple, mundane predictable things, like the hard sciences, where as schizophrenics are mental hares, liberals, and are prone to wild speculations and flights of fancy, attempting to make broad connections between vastly different people, places, things and subjects, that often aren’t connected at all, reading too much into things.
Asperger’s focus is too narrow, too precise, which is why they have trouble with things that’re too varied to process by linear, rigid, sequential thinking, where as Schizophrenic thinking is too broad, wishy washy, all over the map, or at least too much for our tastes, as neurotypicals.
But who is a neurotypical anyway, am I, are you?
Neurotypical is just an average, and none of us are average in every way, all the time, we all diverge from the average from time to time, from way to way, more or less.
Averages are abstractions.
