Temporary Insanity

Is it possible for a regular person to plea temporaray insanity? To simply state that they have lost their damn mind? I think this happens a lot actually, a person for one reason or another might lose their insight and live in a bubble of irresponsability and crazyness and there's no other way of explaining this but to admit that sometimes, we all just go insane even if it's for a moment. It might not be as serious or it might be, it really depends but I'm pretty sure it's possible and I'm pretty sure, it's happening somewhere as we speak.
