Need a New Name

Okay, so I've been looking for a new name for my account, once again, and instead of going with a support name, I'm trying to find a demons name.

I want the demon that causes insanity or something like that. Something that has to do with the mind, but all I find is a demon called Aka Manah which is a male demon, but I am trying to find a female demon's name that causes something that has to do with the mind.
