I highly doubt this is a publicity stunt simply because this is BAD publicity, even by modern pop culture standards.
It doesn't exactly benefit her for the world to think she's a neo-nazi psychopath. As people have said here, its pretty much career suicide.
As far as I can tell, though I'll openly admit I'm not exactly a doctor, aneurysm can lead to changes in personality. So its a pretty safe bet, I think, to assume her brain was kinda fried.
Honestly... I kinda feel a little sorry for her.
