Q

error theories of aging

A

based on assupmtion that aging is affected by outside forces

no internal clock
suggest that aging is caused by factors that affect normal cell processes - free radicals, disease, genetic mutation

Q

once reach middle adulthood, leading cause of death is

A

disease

29
Q

wear and tear theory

A

the longer we live, the mor elikely our tissues will wear down + eventually die

humna body ages as result of use, overuse, + environmental stressors

physical trauma, environmental toxins, overuse
compare to car
weismann

generally considered outdated

30
Q

brain vol changes across lifespan

A

early adolescence + young adulthood = waves of growth
after age 35 = dec in vol

31
Q

greater dec in brain vol in later yrs, is correlated with

A

reduce cognitive abilites + slower reaction times

32
Q

what findings suggest that vol loss of brain may have little to no bearing on function

A

that older adults lose vol in preforntal cortex, but use it more than adolescents

result in functional brain plasiticity

33
Q

leading cause of death for older adults in canada + industrialized natiosn

A

cardiovascular disease

develops from dec in flexibility of veins + arteries + dec efficiency of heart muscle to pump

34
Q

consequences of aging + less activity

A

arteriosclerosis (hardening of arterie) + coronary artery disease (plaque builtup in arteries)

35
Q

most common issue in skeletal system as people age has to do with

A

loss of bone mass due to diminishing minerals + calcium

36
Q

rheumatism

A

pain in the bones, ligaments, tendons, or muscles not caused by accidents

leading cause of lack of mobility in elderly

37
Q

2 main types of rheumatism

A

rheumatoid arthritis
osteoarthritis

38
Q

rheumatoid arthritis

A

type of arthritis classified as an autoimmune disease in which body’s own immune system causes an inflammation of tissue arnd joints

immune system causes deterioration in cartilage + linings of joints betw bones

swelling, pain, significant restriction of mobility

39
Q

osteoarthritis

A

most common type of arthritis
cartilage of joints to gradually diminish over time
results from use + abuse of skeletal system

hands, lower back, neck, knees, hips

type of arthritis where skeletal joints + tissue wear down over tiem

40
Q

most common treatment for both types of arthritis

A

medication for pain releif

acetaminophen + ibuprofen - without prescription

prescription - narcotic painkillers _ cortisone

most drastic is surgury by realigning bones, fusing bones, or replacing bones

41
Q

osteoporosis

A

degenerative disesae fo the skeletal system in which bone loss or resorption results in weakened + brittle bones

disruption of bone remodelling causing bones to become brittle + weak

42
Q

adls activities of daily living

A

necessary behavioural function of individs in order to meet basic survival needs, like eating, dressing, elimination + others

43
Q

planned sequential movements require

A

coordination among muscular system, endorcine, + brain
hormone issues can affect ability to make these movements

44
Q

abilities that require information processing

A

maintina conversation
read newspaper
watch tv
read intructions on medication

45
Q

selective attention

A

ablity to attend to particular item in environment while inhibiting other distracting stimuli

ability to destinguish betw relevant + irrelevanet info

may be affected as visual systems dec

46
Q

tope-down processing

A

forming perceptions beginning with a more general idea + then working toward more detailed info

involves higher-level thought processes like executive function

you know your friend has red heair, so you look for that colour when she gets off airplain

47
Q

bottom-up processing

A

forming perceptions from smaller, finer details + then building upward into a solid general idea

occurs at sensory level, cahnges in visual acuity + auditory processing mainly affect bottom-up processing

friend coming off airplane yells your name

48
Q

attention requires both

A

top-down processing + bottom-up processing

49
Q

both top-down + bottom-up processing appear to dec in older adults, which one dec faster?

A

top-down

50
Q

cognitive dec is accompanied by cahnges in

A

brain function + dec in visual + perceptual sensitivity

51
Q

changes i working memory are correlated with a dec in brain activity associated iwth the

A

hippocampus

remembers long apst memories, working/short term memory worse, can’t rememebr where her glasses are

52
Q

tip-of-the-tongue phenomenon

A

feelign you know a piece of info, but cannot recall it

older adults experience it more frequently than adolescents or younger adults

53
Q

wisdom

A

acccumulation of knowledge + experience, along with personal insight + common sense

debated
more than just knowledge + expertise

combination of common sense, experience, personal insight along with tolerance, reason, + solid decision-making

soemwhere betw self-actualization + ability to communicate thoguhts + perceptions intelligently

54
Q

visual dec began in middle adulthood, + continues +

A

becomes more significant in later yrs

55
Q

presbyopia

A

farsightedness - can’t read small print/stuff close

continues as eyes cahnge in shape + become smaller

56
Q

in old age the retina

A

becomes less sensitive to light + causes difficulty to see at night

57
Q

cataracts

A

shaed areas of the lense of the eye that can be treated surgically

shading + discoloration of lens of eye

58
Q

glaucoma

A

inc pressure within the eye that , if left untreated, can lead to serious vision problems
inc pressure due to restriction of movement of liquid betw cornea + lens
needs early treatment

59
Q

age-related macular degeneration

A

leading cause of vision loss for older adults, caused by deterioration of central region of retina

deterioratio of central region of retina, causes significant visual difficultly

leading cause of vision loss in canadians
if late stages, treatment can only slow vision loss

main approach to treating = visual rehabilitation - teaching people to use remaning vision more effectively

60
Q

most individs over 75 report

A

partial or significant hearing loss

61
Q

between olfactory (smell) and gustatory (taste) which dec faster/earlier in older adults

A

olfactory/smell dec faster/earlier

both affect quality of life

62
Q

sensations like cold + heat, have higher thresholds as we age bec

A

age is associated iwth dimisnihing abilty to feel sensations

most common in latin america

dificiencies of cognitive + intellecuatl ability, inability to plan + organize, memory loss, language impairment, diminishing mobility + difficultly recognizing familiar people

intereres with behavioural + psychological function

66
Q

vascular dementia

A

common dementia caused by restricted supply of blood to brain

typically after minor strokes

second most common form of dementia 20% of dementias

memory impairment, loss of communication skills, gradual deterioration in person’s ability to carry out daily tasks + acitivities of living

67
Q

lewy body dementia

A

round lewy bodies structures develop in parts of the brain involving thinkcing + movement = visual hallucinations, delusions, _ inc rates of falling

no cure

68
Q

alzheimer’s disease

A

most common form of dementia in world
1/20 over 65 has it
1/4 over 85 has it

5-10% of cases due to familial autosomal dominant alzheimer’s

rest are sporadic

usually individs over 60
irreversable + progressive, gradually destroying brain + abillity to remember, think clearly + perform activities of dialy living

progressive form of dementia in whihc plaques + tanlgues form in brain, resulting in incing memory loss + eventually death
