Geriatrics

Geriatrics is the branch of medicine that focuses on health promotion and the prevention and treatment of disease and disability in later life. The term itself can be distinguished from gerontology, which is the study of the aging process itself. The term comes from the Greek "geron" meaning "old man" and "iatros" meaning "healer", and was proposed in 1909 by Dr. Ignatz Leo Nascher. It is cognate with Jara in Sanskrit which also means old.
