what is the most common theme across all theories of aging?
change
change is considered development in early life, and aging in later life
life expectancy factors
heredity, disease processes, medical procedures, lifestyle choices, nutrition
senescence
aging-related changes that lead to a decreased ability for adjustment and survival
programmed theories (non-stochastic)
aging has a biological timetable or internal biological clock
aging is predetermined, timed phenomena
(programmed senescence, gene theory, endocrine theory, immunologic theory, nutritional theory)
damage/error theories (stochastic)
aging is a result of internal and external assaults that damage cells; random processes accumulate overtime and inflict damage
(wear & tear, cross-linking, free radicals, somatic mutation, environmental theory)
programmed senescence
cells natural loss of function overtime
(eg. “Hayflick’s Limits”: fibroblasts can only divide a certain amount of times)
gene theory
aging is programmed due to one or more harmful genes within each organism
endocrine theory
biological clocks act through hormones to control the pace of aging
dysfunction in the hypothalamus causes age-related changes
immunologic theory
aging is due to decreased T cells and causes increased susceptibility to diseases
decline in immune system
nutritional theory
diet affects aging
quality of diet is important due to vitamin and nutrient deficiencies
wear and tear theory
internal and external stressors damage body components over time
cross-linking theory
DNA/proteins cross link with sugars, become stiff and inhibit normal metabolic activities
free radicals
accumulation of toxins damages the cell membrane; anti-oxidants neutralize toxins
somatic mutation
DNA damage (telomeres) leads to chromosome abnormalities
environmental theory
number of environmental factors are known to threaten health
ingestion of lead, arsenic, pesticides, second hand smoke, & air pollution
role theory
as people evolve through life stages, their roles evolve as well
adaptability is a predictor of adjustment to aging
person-environment fit theory
changes in competencies and needs due to aging influence ability to deal with environment
activity theory
activity is necessary to maintain life satisfaction and positive self-concept
continuity theory
maintain a consistent pattern of behaviour, continuation of life roles slows aging
disengagement theory
no longer supported
natural seperation of old people from society to transfer power to younger generations
age stratification
society consists of cohorts that age collectively and influence each other, and are influenced by significant events
selective optimisation with compensation theory
individuals develop strategies to manage and cope with losses of function that occur over time
gerotranscendence
spirituality has a greater role in life and in acceptance of death
