Curable insanity is the question though.

Some people go insane from brain tumors and CSF leaks. These can be cured, and can literally return a person to a "normal" state of mind overnight.

Then there are things we just can't cure yet because there's a seemingly unfathomable amount of stuff going on in the brain with regards to chemicals.

If their cause can be medically cured with past results backing a return to normalcy... I think that should be a large part of the legal discussion and attempted if the defendant requests. Whether or not they lie about being normal again after the procedures? Well, that's a question as hard as why are some people just dicks.
