Mental changes only if they cured problems and gave improvements, I wouldn't want new personality traits and such.
Actually a cool way to get around mind alteration would be buffs if you act a certain way during your new life, like bravery/cruelty is better at combat, temperance/greed is better at making money, etc, and if you don't strongly fit into any personality archetypes (npc moment) you get a slight increase to everything to keep things balanced and fair.
