Geriatric Medicine

The two essential bodies of knowledge that comprise the science of geriatrics are gerontology and geriatric medicine. Gerontology (from the Greek γέρων, geron, “old man” and -λογία, -logia, “study of,” coined by Ilya Ilyich Mechnikov in 1903) is the branch of basic sciences that explores the process of aging, with the focus on the psychological, cognitive, and biological aspects of aging. Geriatric medicine, or geriatrics (from the Greek γέρων geron meaning “old man” and ιατρός iatros meaning “medicine related,” coined by Ignatz Leo Nascher), is the branch of medicine that deals with the problems and diseases of old age and aging people [1]
