Issues faced by older adults Flashcards
(93 cards)
Appearance changes
Skin
–> skin becomes wrinkled, may show age spots, moles, varicose veins, capillaries and arteries become more visible
Hair
–> hair goes grey, thins and is lost over time. Women may gain facial hair with the menopause
Appearance changes may impact insecurity and wellbeing.
Shrinking pupils
There is a reduction in the amount of light entering eye, which makes it specifically hard to adapt to darkness - takes around 40 mins for an 80 year old to adapt to darkness
–> this may be important in the home (could lead to falls)
–> this may impact driving
Decline in lens elasticity
It becomes harder to see objects that are close (presbyopia)
it is harder refocussing from near to far (bifocals), which lenses can help with
what is presbyopia?
difficulty in clearly seeing objects up close - caused by decline in lens elasticity
what are bifocals?
difficulty in refocussing from near to far
what are cataracts?
this impairs central vision because there is decreased transparency of the lens
it makes us sensitive to glare, as light can be scattered
causes hazy vision
what is glaucoma?
fluid in the eye cannot drain properly so there is high pressure internal damage leading to vision loss
what is macular degeneration?
a degenerative condition affecting the central part of the retina (the macula) and resulting in distortion or loss of central vision - everything looks blurry.
what are the implications of visual changes in life?
- Driving
- Shopping
- Activities of daily living
- Postural problems
- More vulnerable to falls (unable to see hazards, judge distances, and have to rely more on proprioception rather than vision)
- Social interaction
- Well-being
what is cataract surgery?
this replaces the cataract. It very common and many older adults require it so it is strenuous for the NHS. For this reason they often operate on the most impaired eye and it is less common to operate on both.
why are cataracts so bad for driving?
People with cataracts experience more problems when driving. For this reason, older adults often self regulate their driving behaviours. This is particularly important at night as bright lights could cause scattered vision. Those who undergo cataract surgery show improved driving (Wood & Carberry, 2006).
how do cataracts impact falls and motor function?
Sheppard et al. (2022)
- second eye surgery had a positive impact on mobility and fall rates
- second eye surgery is not very pronounced on driving showing that it may not be super important
driving in older adults
- driving requires many abilities such as cognitive, physical, sensory
- these all decline with age, making it hard to drive
- many older adults choose not to drive or they self regulate their driving behaviours and routes
- older adults who stop driving are negatively impacted in other aspects of living, such as greater depressive symptoms, less social engagement, and poorer functional status
what is presbycusis?
age related hearing impairment:
- Difficulty hearing high pitched tones as well
- They are troubled by background noise – unable to filter out
- This impacts mental health as it affects communication and loss of independence
- Variable – is impacted by exposure to loud noise throughout life
Balance problems
- Impaired joint position sense
- 40% of vestibular hair and nerve cells lost by age 70 which causes postural adjustments that are too small
- Increased dizziness and vertigo
- Increased likelihood of falls
What happens to muscle strength?
Muscles lose their force, especially severe in nursing home residents who are prone to falls
What happens to muscle endurance?
reduction in muscle mass (sarcopenia) and muscle fibers
how can reductions in musculoskeletal changes impact older adults psychologically?
- Joint problems limit movement and independence
- Muscle coordination declines, so OA move more slowly
- Avoidance of some environments
- Access problems (hard to walk up stairs)
- Fear of falls
how do our bones change in older adulthood?
- Bone loss starts in late 30s and accelerates in women post-menopause because of less oestrogen.
- Bones become more hollow where they lose mass, more brittle and porous
- Increased likelihood of fractures
- Osteoperosis
what is osteoperosis?
- Bones become weak and fragile and more likely to break (fracture).
- Causes pain
- Older adults with this are ,ore likely to fall, and more likely to be badly affected by the fall due to brittleness of bones
- 3 mil in UK have osteoporosis
how is osteoporosis prevented?
–> Largely diet, weight, exercise, genes
Osteoporosis stepwise implementation model tries to reduce the problem of osteoporosis at a prevention level through to efficiency of care post-osteoporosis, tackles each level of the problem
why are falls such a problem?
30% of adults 65+ have a fall every year
- Linked to osteoporosis, many bone fractures are preceded by falls
- Can be caused by many things such as vision, hearing, vestibular system, inadequate muscle strength, polypharmacy effects on balance, slower reaction times, environmental hazards
- Falls impose a significant social and economic burden for individuals, families, the health service and economy
- See currently guidelines for preventing falls: Age UK and NHS
How to prevent falls by modifying the environment?
- Assistive devices can be used to prevent falls
- Improved lighting to reduce shadow
- Eliminate tripping hazards
- Home safety evaluation
How to prevent falls by exercise training?
Sherrington et al. (2017) found that exercise reduced fall rates in community-dwelling older adults by 21%
- High challenge balance training was best for reduction in fall risk over high intensity or walking training exercise
- It was better to do 3+ hours a week of exercise rather than 2+
Sherrington et al. (2019) review
- Exercise reduces the number of falls over time by around one-quarter (23% reduction).
- There is not enough evidence to determine the effects of exercise programs that are either resistance, dance or walking programs.
- No evidence to determine the effects of programs that were mainly flexibility or endurance based exercise
- Does this link to current guidelines?
