Q
Changes noted with vision and aging:
A
- Diminished acuity
- Diminished ability to accommodate for changes that occur with light/dark
- Decreased figure ground
- Decreased ability to discriminate between colors
- Visual field narrows
- Decreased depth perception
11
Q
Glaucoma:
A
- Occurs when the aqueous (fluid behind the cornea) builds up within the eye
- Result is low blood flow to the optic nerve and hence reduces vision
- Person losses peripheral vision and visual fields
- If not treated, one can go blind
- Treated with drops/surgery
12
Q
Muscular Degeneration:
A
- Leading cause of blindness in people over 60 years old
- The eye structure involved in the retina
- A person’s central vision is affected
- A person can not read standard print
13
Q
Cataracts:
A
- The eye structure affected is the lens
- The lens become opaque and thickens
- A person may complain of hazy/cloudy vision or blurred vision
- A person may have to get reading glasses for near vision
14
Q
Diabetic Retinopathy:
A
- Leading cause of blindness of all ages
- Usually occurs in an individual with poorly controlled diabetes
- Blood vessels rupture in the eye causing blind spots in the central vision field
- Can cause retinal detachment
15
Q
Parkinson’s
A
- may have difficulty with eye movement (up gaze and converging)
- problems with convergence can cause double vision
16
Q
Alzheimer’s
A
difficulty with color perception as well as depth perception
17
Q
What needs to be considered when a person have low vision?
A
- Lighting
- Contrast (Dark/Light)

19
Q
Technology for low vision:
A
Bioptic telescope system

- May appear to have a short attention span
29
Treatment Intervention for Hearing Loss:
- Five minute hearing test

- Visual aids within the environment
30
Integrative Strategies for hearing loss:
- make changes in the social and physical environment of the elder
- go out to eat between the busy times of the day
- add drapes, carpet, wall to ceiling coverings to reduce ambient sounds in the home
31
Mutation Theory:
- genetic, nonprogrammed
- accumulated errors of DNA/mtDNA
- Baseline for cancer
32
DNA-RNA Theory:
- disassociation of the RNA from the DNA
| - Results in cell death and then organ failure
33
elders typically withdraw from previous activities in preparation for death
Disengagement Theory
34
Free Radical/Oxidative Stress Theory

38
what presbycusis is loss of high frequency sounds which is a result of degeneration of the basal end of the organ neurons
sensory presbycusis
39
what presbycusis is progressive degeneration of the auditory neurons in the auditory pathway of the cochlea
neural presbycusis
40
what presbycusis is stiffening of the basilar membrane. interferes with vibration mechanism with the cochlea duct. can lead to a loss of hearing of all frequencies
mechanical presbycusis
41
what presbycusis is a result of atrophy of the blood vessels in the cochlea's wall. reduction in pure tone sensitivity of all frequencies is accompanied by rapid increase in loudness as the sound intensifies.
metabolic presbycusis

5. final action-sent to president
71
Telomere Shortening
a sequence of DNA at the end of a linear chromosomes that protect the DNA from mutation and ID strand for replication.
- Reduce replication which eventually can lead to cell death.
72
a type of incontinence that is sudden and is usually caused by an illness or condition
Acute Incontinence
73
involuntary loss of urine due to intr-abdominal pressure (ex. coughing, laughing, exercise)
Stress Incontinence
74
bladder muscles are overactive- creating a sense of urgency
Urge Incontinence
75
e bladder is always full. The elderly person can never fully empty it. Constant dribbling of urine and/or voiding only small amounts noted.
Overflow Incontinence
76
Stress ( intra-abdominal ) and Urge (urgency/void low volumn)
Mixed Incontinence
77
lose all awareness of the need to void ( SCI)
Reflex Incontinence
78
loss of urine due to cognitive ( dementia - Alzheimer's) or
| •Mobility reasons ( walk slow, walker , etc) Will see the elderly rush to the bathroom .
Functional Incontinence
79
increases production of urine and hence the bladder fills more rapidly
Diuretics
80
relax muscles and decrease awareness for the need to void
Sleeping Pills
81
tighten the pelvic floor muscles. This makes it difficult to void
Decongestants
82
relax the bladder and prevent it from contracting properly
