An aging-associated disease (commonly termed age-related disease, ARD) is a disease that is most often seen with increasing frequency with increasing senescence. They are essentially complications of senescence, distinguished from the aging process itself because all adult animals age ( with rare exceptions ) but not all adult animals ...
Depression is one of the most common disorders that is present in old age and is usually comorbid with other physical and psychiatric conditions, perhaps due to the stress induced by these conditions. [93] In older adults, depression presents as impairments already associated with age such as memory and psychomotor speed. [94]

Tau protein disorders cause microtubule destruction and formation of neurofibrillary tangles. Age-related neuropathologies such as Alzheimer's disease, Parkinson's disease, diabetes, hypertension and arteriosclerosis make it difficult to distinguish the normal patterns of aging.
The hand of an older adult Life expectancy in various countries of the world in 2019. Biogerontology is the sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. [1]
Progeroid syndromes (PS) are a group of rare genetic disorders that mimic physiological aging, making affected individuals appear to be older than they are. [1] [2] The term progeroid syndrome does not necessarily imply progeria (Hutchinson–Gilford progeria syndrome), which is a specific type of progeroid syndrome.
Aging is characterized by the declining ability to respond to stress, increased homeostatic imbalance, and increased risk of aging-associated diseases including cancer and heart disease. Aging has been defined as "a progressive deterioration of physiological function, an intrinsic age-related process of loss of viability and increase in ...
In the field of sociology and mental health, ageing is seen in five different views: ageing as maturity, ageing as decline, ageing as a life-cycle event, ageing as generation, and ageing as survival. [127] Positive correlates with ageing often include economics, employment, marriage, children, education, and sense of control, as well as many ...
