Charles ensured his domination and throne by having his mother confined for the rest of her life in the now-demolished Royal Palace in Tordesillas, Castile.<ref>{{cite web |title=Palacio Real |url=http://www.tordesillas.net/-que-ver-/guia-de-monumentos/palacio-real |website=Turismo de Tordesillas |publisher=Oficina de Turismo de Tordesillas |access-date=30 October 2018 |language=es |archive-date=17 January 2020 |archive-url=https://web.archive.org/web/20200117081136/http://www.tordesillas.net/-que-ver-/guia-de-monumentos/palacio-real |url-status=dead }}</ref> Joanna's condition degenerated further. She apparently became convinced that some of the nuns that took care of her wanted to kill her. Reportedly it was difficult for her to eat, sleep, bathe, or change her clothes.

Her late mother's lady-in-waiting, [[Catalina de Medrano y Bravo de Lagunas#Lady-in-waiting for Queen Isabella I of Castile|Catalina de Medrano y Bravo de Lagunas]], along with her husband, Hernando de Sandoval y Rojas, took part in the custody and care of Joanna in Tordesillas.<ref>Tomás Gismera Velasco, Guadalajara in Memory, New Alcarria Newspaper, Guadalajara, August 7, 2020</ref> Joanna also had her youngest daughter, Catherine of Austria, with her during Ferdinand II's time as regent, 1507–1516. Her older daughter, Eleanor of Austria, had created a semblance of a household within the palace rooms. In her final years, Joanna's physical state began to decline rapidly, with mobility ever more difficult.
