[Batman] What's the Joker actually diagnosed with?

Yes, Arthur Fleck is genuinely quite mentally ill. But the other incarnations just seem like, well...assholes.  


He's not delusional or hallucinating. He's fully in control of his emotions and actions when he wants to be. He has a reasonably undistorted view of reality. He's got normal mental capacity (above average, indeed). He doesn't have compulsions or depression or such like. Apart from some empathy issues (and even then, he clearly understands other's emotions and personalities and goals on a deep, non-superficial level), guy seems pretty *sane*, just weird and dangerous.  


He's a violent, murderous prick, sure. But that's not a mental health condition- you can't get the insanity defense just for killing people, that's absurd, and simply dressing like a clown doesn't count.  


So what's his actual medical diagnosis? What's the condition he's getting the insanity defense for?

Oh...  oh no.  An actual diagnosis would require a trained psychologist to spend a great deal of time listening to him in order to make the diagnosis.  Historically that sort of thing has not ended well.

I suppose Dr. Quinzel could have put in a diagnosis before she snapped, but those notes have been destroyed.
