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.
