Aging Flashcards
What are some musculoskeletal age related changed?
- Sarcopenia
- Decreased velocity of muscular contraction
- Decrease in strength
- Decreased cross sectional area of muscle fibers
- Collagen stiffness
In aging population do men or women have a greater loss in bone mass
Women - Women experienced greater loss of bone mass following menopause
What percentage of strength is lost per decade in the aging population?
10%
What are some cardio/pulmonary age related changes?
- Increased calcification of valves
- Decreased arterial elasticity
- Decreased muscle strength
- Decreased forced expiratory volume (FEV)
- Increased residual volume following max expiration
What are some neuro age related changes?
- Decreased brain weight & volume
- Increased ventricular size
- Decreased nerve speed & conduction
- Decreased reaction speed
What are some integumentary age related changes?
- Decreased sensory perception
- More prone to hypo/hyper-themia
- Impaired thermoregulation (decreased sweat glands)
- Decreased elasticity & thickness of dermis
What are some metabolic & endocrine age related changes?
- Decreased sensitivity to insulin
- Metabolism decreases
What some gastrointestinal age related changes?
- Decreased energy/drug metabolism
- Increased risk of adverse side effect
- Decreased bowl motility
- Decreased gastric acid production
What are some genitourinary age related changes?
- Increased size of the prostate
- Increased incontinence
- Decreased kidney functioning including filtration rate
- Decreased bladder capacity
What is most common cognitive impairment associated with aging?
Memory loss
Which type of memory is most affected in older adults?
Short term - Older adults have difficulty recalling information they learned recently
What is semantic memory?
Facts, knowledge of specific information
What is procedural memory?
Performance of a specific procedure or skills
What is working memory?
Use of relevant information during a task
What is episodic memory?
Lived experience, personally experienced
While both working and short term memory decreases, which decrease more?
Short term
Of episodic, semantic and procedural which memory is affected the most?
episodic
Does sustained and selective attention show a decline in age?
No, not in comparison to divided attention
What is sustained attention?
Maintaining attention over a long period of time
What is selective attention?
Ability to selective disregard items that are relevant to that specific task
What is divided attention?
Ability to process two more sources of information at the same time
Which type of attention declines the most?
Divided
Deficits in divided attention leads to what risk?
Increased fall risk (generally prioritize motor tasks)
Which type of intelligence is know to decline with age? (General, Crystallized or Fluid)
Fluid intelligence
