Aging - Definition


Aging is a normal process that affects the body and all of its functions. When referring to biological aging we use the term senescence, as opposed to dementia, which refers to a pathological aging condition. The study of aging in different fields is called gerontology, with geriatrics representing the medical specialty focused on treating the elderly. Aging is a ubiquitous process, meaning that it affects all the cells, tissues, and organs of the body, without exception. Some people, however, or certain conditions, present with premature aging (dementia) causing organ failure due to impaired function.
