Late Adulthood Flashcards
Ageism
Prejudice in which people are categorized and judged solely on the basis of their chronological age (Elderly view ageism as a self-fulfilling prophecy)
Sleep
Day-night circadian rhythm diminishes with age, older people wake before dawn and are asleep during the day
Exercise
Only 35% of people over age 65 meet recommended guidelines for exercise
Elderspeak
Condescending way of speaking to other adults that resemble baby talk
Destructive protection
Elders discouraged from leaving home
happiness in older people is equivalent to what age group
As common as in younger adults
Gerontology
Multidisciplinary study of old age
Geriatrics
Medical specialty devoted to aging
Demographic shifts
More older people in the world than there used to be
Reasons for the pyramidal age graph shape
(1) Far more children were born than the replacement rate (2) Before modern sanitation and nutrition, many children dies before age 5 (3) Before, Middle aged people rarely survived adult diseases
Dependency ratio
Estimating the proportion of the population that depends on care from others, comparing number of dependents to number of people in the middle
Young-old
Healthy, vigorous and financially secure older adults that are well integrates into the lives of their family
Old-old
Those who suffer from physical, mental or social deficits
Oldest-old
Early adults who are dependent on others for everything
Compensatory strategies involve what?
Personal choice, societal practices, technological options
Selective optimization
Focusing on those things that can be done well rather than focusing on cognitive loss and physical loss with age
Cataracts
Thickening of the lens causing vision to become cloudy, opaque and disorted
Glaucoma
Buildup of fluid within the eye that damages the optic nerve
Macular degeneration
Deterioration of the retina (spotty vision)
Atrophy in elders
Inevitable
Primary aging
the universal and irreversible physical changes that occur to all living creatures as they grow older
Secondary aging
Specific physical illnesses or conditions that become more common with aging
Treatment of the elderly: Flu
Important for elderly to get vaccinated, even though protected against only B not A strain
CVD
Less than half have over age of 65 but by 90 almost everyone has either CVD, Dementia or diabetes
Compression of morbidity
Less time elders spend ill or infirm which is due to new technology advances and improvements in lifestyle
Effects of falling
Bones become more porous, losing calcium and strength leading to osteoporosis
Genetic clock
Mechanism in DNA of cells that regulate the aging process by triggering hormonal changes controlling cellular reproduction and repair
Disposable soma theory
each body has a certain amount of physical energy and strength which is gradually spent over a lifetime
Transplants
Can add years to your life because you have a healthier parts of your body
Obesity
Overweight and obese individuals die at a younger age because of the amount of energy they use
Progeria
Genetic disease that stops growth at about age 5, children age very fast and usually die in their late teens
Grandmother hypothesis
When menopause hits as a sign that the woman cannot have any more children and should start helping with grandchildren
Oxygen free radicals
Atoms of oxygen that have unpaired electrons that can cause disease
Hayflick limit
Suggests that human cells are capable of duplicating into two new cells approximately 50 times indicating lifespan is limited
Telomeres
Length of chromosomes decrease with each cell duplication and correlates with longevity
B cells
Immune cells manufactured in bone marrow create antibodies
T cells
Manufactured in thymus gland and produce substances that attack infected cells in the body
Average life expectancy
Number of years that the average person in a particular population is expected to live
What promotes longevity?
Diet, Family and community, Exercise and relaxation, Work
What state has people living the longest
North Dakota
What religious group in the US is known for communities where people live long lives?
Seventh day adventists
What qualities of life did researchers say increase lifespan?
Moderate diet, hard work, optimism, intellectual curiosity, social involvement
Neurons and dendrites grow in what region?
Olfactory and hippocampus region
New neurons provide what to succeed in context of challenges and changing environments?
Cognitive adaptability
Brain slowdown correlates with what?
Slower walking and most other physical disabilities
Senescence reduces production of neurotransmitters which do what?
Allow a nerve impulse to jump quickly
Which ares of the brain shrink the fastest?
Hypothalamus and Prefrontal cortex
Compensation with the brain
Older adults move more parts of their brain for simpler tasks
Reduced brain reserves
Makes challenging tasks even harder
