In the largest study of its kind, researchers have investigated the caregivers of 186 mothers to childhood brain tumor survivors aged 14-40 whose care needs last long into adulthood. They discovered that a complex interaction among the health of the caregivers, the demands experienced by the caregiver, the caregiver’s perceptions about the health of the survivor, and the family’s support interact to explain how the caregiver assesses herself in her role.
