Informal caregivers provide unpaid, often substantial, care and support to family members or friends who are unable to care for themselves due to illness, disability, or aging. This research area focuses on the experiences, challenges, and needs of informal caregivers, as well as the impact of caregiving on their physical, emotional, and financial well-being. Studies in this area may examine the effectiveness of support services and interventions for caregivers, such as respite care or educational programs, as well as the healthcare system's recognition and support of informal caregivers. Understanding the role of informal caregivers is crucial for developing policies and strategies to better support both caregivers and care recipients.
