Gerontology is the scientific study of the aging process. It is a multidisciplinary field that draws from the biological and psychological sciences. Geriatric medicine is the practice that focuses on the physiology, pathophysiology, diagnosis, and management of disorders and diseases of the elderly. Because aging is a natural process, the care of the elderly cannot be limited to a single specialty but rather through a collaborative effort. Geriatric nursing is a multidisciplinary approach to providing care that combines expertise and resources to provide comprehensive geriatric assessment and nursing interventions. Nurses collaborate with a medical team to provide appropriate services to patients and provide comprehensive care.
