what model of aging says that aging is due to intrinsic timing
programmed model of aging
aging is changes in adaptability to ___
stressors
when does it become disease instead of aging
when it changes a person’s ability to function
what is lipofuscin

which is the only organ that doesn’t decrease in size as we age?
prostate
what impacts wound healing in aging?
fewer mast cells and macrophages
which aspect of muscle performance is most impacted by aging?
power
which fiber type is most affected with aging?
type II (fast twitch)
polymyalgia rheumatica
over 50, relapsing, systemic disease of pain, weakness, and stiffness in proximal muscle groups
older adults use ____ processing for spatial tasks, but need to use ____ processing in novel environments (find thins difficult)
egocentric = self to object allocentric = encode relationships of objects to each other
why are elderly more prone to hypERthermia?
decreased sweat production
presbyopia
ability to change focus from far to near declines
far vision is easier because…
it is achieved by muscle relaxation
glaucoma
loss in peripheral vision
increase in intra-ocular pressure
macular degeneration
loss of central vision
cataract
increase density of lens –> blurring
diabetic retinopathy
leaking blood, blocks vision
how does poor vision impact gait in the elderly?
more time in DL stance
don’t pick up feet as high on stairs (AP stability better than M/L)
presbycusis
sensorineural hearing loss
atrophic gastritis
chronic inflammation of the lining of the stomach that results in poor absorption of B12 and pernicious anemia
will have no pain
need B12 shots
decreased kidney function in the aging affects drugs by….
decreasing metabolism, last longer in the body
how does aging increase OH?
baroreceptors become less sensitive, don’t react as quickly
which type of intelligence is affected by aging?
fluid intelligence
symptoms of normal pressure hydrocephelus
dementia
slows-shuffling gait
urinary incontinence
postprandial hypotension
low BP after you eat
Berg is good for CVA but not as good for PD T/F
true
good questioniaire for fear of falling
ABC fear of falls scale
which muscles are important to strengthen to improve balance in the elderly?
DF, quads, hip flexors
frailty is
3 or more -unintentional weight loss -self-reported exhaustion weaknes slow walking speed low physical activity
what is the most common type of dementia
alzheimer’s
dementia is at least 3 spheres of mental activity
language memory visuospatial skills emotion cognitive
primary difference between dementia and delirium
acute onset of delirium
and level of consciousness is altered by delirium
apraxia
impaired ability to do previously learned motor activities despite intact motor function
which type of dementia has prominent hallucinations?
dementia w/ Lewy bodies
what two is mixed dementia
is vascular dementia and AD
frontotemporal dementias
degeneration pattern of the frontal lobe
which type of dementia causes fluctuations in cognition
dementia with lewy bodies
medical management of AD
acetylcholinesterase inhibitors
most common neurocognitive test, and what is its downfall
mini mental
doesn’t do executive function (add clock drawing test)
what organ is most responsible for drugs staying in the system of elderly the longer?
the kidneys
