neruomus Flashcards
how is the percentage of reduction of the CNS as we age
40% by 80
what does the reduction of the CNS stress
the redudent systems
what does slouging of the myelin sheath mean
reduction of MS
what does reduction of the MS lead to
decreased nerve conduction
effects the :
- sensory and motor systems
- voluntary and reflex
what happens with neuromusclare connections with aging
loss of neuromuscular junction connections
less fin control
aging and motor co-activation
increases with age
does baseline matter in terms of cognition changes
yes
cog is very indivdualized
life experiences, genitics, enviroment
as we age what happens with the speed of cognition
slower processing speed
what happens with attention as we age
diminishes
attention and switching attention
what does (delayed) free call mean
spontaneous retrieval of info from memory without a cue
recalling a list of food to buy from the grocery store
what is source memory
knowing the source of learned infromation
remebering that you learned a fact becasue you saw it on television or becasue you read it in a book
what is prospective memory
remebering to perform an intended task in the future
take meds before going to bed
what is recognition memory
the ability to retrieve info when given a cue
give the details of a store when given yes or no questions
what is temporal order memory
remembering the right seq of events
remembering that you went to the grocery store before you went out to lunch last saturday
what is procedural memory
remebering how to do things
how to ride a bike
what kind of memory declines are age
free recall
source memory
prospective memory
what kind of memory remain intact as we age
recoginition memory
temporal
procedural memory
what are the 5 senses
hear
sight
touch
taste
smell
visual chnages seen with age
increase in farsightedness - cannot see things that are close to the eyes
is macular degeneration a normal aspect of aging
no it is pathilogical but common
what is macular degeneration
central vision is progressively lost but peri vision is spared
what PT things is decreased vision related to
falls
mobility issues
what is low vision
this is when someone vision can not longer be corrected to 20/20 vision
things can always be blurring
is age related hearing loss normal
yes, is is related to degeneration of the cochlea
1/2 od aduklts over 85
what kind of freq are lso first for hearing
high freq
lower the registar of your voice when talking with someone with hearing loss
do most individual loss taste and smell when they age
yes
clinical implication of loss of taste and smell
food can lose it appeal - nutrient deficits
hard to maintain muscle mass if their nutrition is poor
if you think someone has nutrition deficits who do you refer them to
registered dietition
what other factor then loss of taste can lead to different eating habits
loss of teeth
what happens to touch nerve ending as we age
loss of merkel discs and meissner’s corpuscles
what happens to the blood supply of sensory organs
decreased peri blood flow
what happens to two point discrimination
decreases
what happens to vibratory sesne
decreases
age as a risk factor
age is a risk factor for many pathologies
common path - cardioplum issues
heart failure
artail fibrillation
CVA - stroke
what is sacropenia
a progressive and generalized loss of skeletal muscles mass and is correlated with physical disability, reduced quality of life, and death
presence of low muscle function
does osteopenia cause pain
no the fractures that they cause do
what is the FRAX
the fracture risk assessment tool
BMI, alc, smoking hisotry, etc.
do we see fracture with just fall
no
