I am so tired of finding almost nothing about Psychopath women in research.

My uneducated theory is that estrogen has some kind of moderating effect on these women. After menopause, whether natural or surgically-induced, watch out. Any controls they once had over their own behavior are gone. They get much, much worse.

Perhaps the androgens kick in. Forget about "burning out" in midlife. They burn on. Perhaps there is a use for life-long hormone therapy?
