On interactions of insanity and gender in modern Jewish fiction, see:
I.L. Peretz, "Be-agaf ha-meshuga'im" (Yid. Fun dul-hoyz), esp. the first section, "Doctor or Patient"?
The following work may also be helpful: Dafna Katsnelson-Bank, Ha-shiga'on ba-sifrut ha-'ivrit be-reshit ha-me'ah he-esrim (2005)
Another lead to follow would be the theme of the dybbuk in modern Hebrew and Yiddish fiction.
