Old Age Flashcards
prejudice or discrimination based on age
o Ageism
– gradual, inevitable process of bodily deterioration that begins early in life and continues through years irrespective of what people do to stave it off (nature
o Primary Aging
results from disease, abuse, and disuse – factors that are often within a person’s control (nurture)
o Secondary Aging
65-74 yrs old
o Young Old
75-84 yrs old
o Old Old
85 and above
o Oldest old
how well a person functions in a physical and social environment in comparison with others of the same chronological age
o Functional Age
study of the aged and aging processes
o Gerontology
branch of medicine concerned with aging
o Geriatrics
the age to which a person born at a certain time and place is statistically likely to live, given his or her current age and health status
o Life Expectancy
actual length of life of members of a population
o Longevity
death rates
o Mortality Rates
longest period that members of our species can live
o Human Life Span
– the decline in body functioning associated with aging
o Senescence
propose that people’s bodies age according to instructions built into genes and that aging is a normal part of development
o Genetic Programming Theories
aging also may be influenced by specific genes “switching off” after age-related losses occur (Epigenesis)
o Programmed Senescence Theory
o Telomeres become shorter as the cell divides (cells can divide for no more than 50 times
Hayflick Limit
– biological clocks act through hormones to control the pace of aging
o Endocrine Theory
programmed decline in immune system functions leads to increased vulnerability to infectious disease and thus to aging and death
o Immunological Theory
Aging is an evolved trait thus genes that promote reproduction are selected at higher rates than genes that extend lives
o Evolutionary Theory
aging is the results of random processes that vary from person to person (Error theories
o Variable-Rate Theories –
– cells and tissues have vital parts that wear out
o Wear-and-Tear Theory
Accumulated damage from oxygen radicals causes cells and eventually organs to stop functioning
o Free-Radical Theory –
the greater an organism’s rate of metabolism, the shorter its life span
o Rate-of-Living Theory
Immune system becomes confused and attacks its own body cells
o Autoimmune Theory
represents the percentage of people or animals alive at various age
o Survival Curve
– backup capacity that helps body system function to their utmost limits in times of stress
o Reserve Capacity
cloudy or opaque areas in the lends of the eyes, are common in older adults
o Cataracts
– leading cause of visual impairment in older adults; the retinal cells in the macula degenerate over time, and the center of the retina gradually loses the ability to sharply distinguish fine details
o Age-Related Macular Degeneration
irreversible damage to the optic nerve caused by increased pressure in the eye
o Glaucoma
exercises or activities that improve daily activity
o Functional Fitness
the general term for physiologically caused cognitive and behavioral decline sufficient to interfere with daily activities
o Dementia
most common type, caused by specific changes in the brain (abnormal build up of neurofibrillary tangles and amyloid plaque in the brain)
Alzheimer’s
a. Amnesia – memory loss
b. Aphasia – inability to express through speech
c. Agnosia – inability to recognize familiar objects, tastes, smells
d. Apraxia – misuse of objects because failure to identify them
e. Anomia – inability to remember the names of things
