There has been increasing research on the experience and needs of caregivers for persons with YOD, who are mainly spouses. Yet one little-explored area is their evolving parental role.

This occurs in much-changed familial context, with children often asked to assume caretaking roles and experiencing strong feelings such as grief, anger, and fear.
