Elderly care is an interdisciplinary field of research and practice dedicated to understanding and addressing the complex needs of older adults. As an academic concept, it investigates the biological, psychological, and social dimensions of aging, the design and evaluation of health and social services, caregiving systems, and policy interventions aimed at enhancing the health, well-being, autonomy, and quality of life for the elderly population. Its significance lies in informing evidence-based strategies, shaping public health and social policy, and contributing to sustainable societal responses to demographic aging.
