Psychological theories of aging
Disease-a-Month, 2015Before elaborating on psychological theories of aging, it is worthwhile to reflect on what this concept implies. Are psychological theories of aging ideas about psychological changes that commonly result from aging, much like physiological changes relate to biological theories of aging, or do we use psychological theories of aging to better understand ...

Human Development, 2009
Aging in mammals appears to be an information loss, probably at the cellular or molecular level. The current models for this process and the prospects for its controllability are reviewed. Stochastic, developmental, clonal and immunological models of aging, which are not mutually exclusive, all offer possibilities for rate-modification in Man, with ...

A bstract An integrated theory of aging is proposed which consists of an interrelated grouping of other current theories. Each of these has had some success in explaining various separate phenomena of aging, but none has provided an explanation of all the phenomena associated

Biogerontology, 2001
The participation theory posits that aging (specified as the age-related deterioration of maintenance functions) primarily results from the participation of some regulatory systems in governing development by means of the expenditure of their resources.

Theories and Mechanisms of Aging
Clinics in Geriatric Medicine, 2011This article discusses various theories of aging and their relative plausibility related to the human aging process. Structural and physiologic changes of aging are discussed in detail by organ system. Each of the organ systems is discussed when applicable to the various theories of aging.

Orvosi Hetilap, 2007
Az eddigi öregedési elméletek mind azt tűzték ki célul, hogy megtalálják az öregedés végső okát, idáig azonban egyetlenegynek sem sikerült megválaszolni azt a kérdést, hogy miért is öregszünk. Az öregedés folyamata meglehetősen komplex, az elméletek azonban csak egy vagy csak kevés elemére koncentráltak.

On the Immunological Theory of Aging
2014Aging is a complex phenomenon the cause of which is not fully understood, despite the plethora of theories proposed to explain it. As we age, changes in essentially all physiological functions, including immunity, are apparent. Immune responses decrease with aging, contributing to the increased incidence of different chronic diseases with an ...

Evolution theory indicates that investment in mechanisms of somatic maintenance and repair is likely to be limited, suggesting that aging may result from the accumulation of unrepaired somatic defects. An important corollary of this hypothesis is that multiple mechanisms of aging operate in parallel.
