Gerontology: the study of aging, including its social, psychological, cognitive, and biological aspects. Gerontology is broader than geriatrics, which is the medical specialty devoted to treatment and care of older people (seniors health). The term is derived from the Greek geron, "old man" and -logia, "study of."
