[Dc Comics] Is there a way to cure Joker?

Is there anyway possible to cure Joker of his insanity or hypersanity as I heard some call it? Is there anything that can make him a normal person?

There's an issue where he thinks he's successfully killed Batman, and he pretty quickly starts life again as a regular guy. Martian Manhunter was able to force his mind into normalcy and Joker felt a lot of regret, but it was temporary. That's pretty much it though.
