Gerontology is the study of aging and older adults. The science of gerontology has evolved as longevity has improved. Researchers in this field are diverse and are trained in areas such as physiology, social science, psychology, public health, and policy.
A more complete definition of gerontology includes all of the following:
Gerontology is multidisciplinary and is concerned with physical, mental, and social aspects and implications of aging. Geriatrics is a medical specialty focused on care and treatment of older persons.
Although gerontology and geriatrics have differing emphases, they both have the goal of understanding aging so that people can maximize their functioning and achieve a high quality of life.
