4.16 Stroke 5 Flashcards
What are some of the spatial relation disorders?
- figure-ground discrimination
- form discrimination
- spatial relations disorder
- position in space
- topographical disorientation
- depth and distance perception
- vertical disorientation
figure-ground discrimination: example of eating dinner
- table is the “groud” or backdrop of what you’re looking at
- plates/etc are the figure
What happens with stroke pts in figure-ground discrimination?
Use in the context of shoelaces
- stroke pts: everything combines
- can’t pull the figure out of the ground
- shoes: can’t discern shoelaces from backdrop of shoes (flattening)
What is spatial relation?
how we perceive ourselves/objects in space
problems with form discrimination
- inability to perceive small differences between objects
- pencil/toothbrush next to each other
What is spatial relations disorder?
- confused with the orientation of one object to another
- disorganized
spatial relations disorder and slide boards/assistive devices
- difficulty getting a slide board in the proper place
- assistive devices: where it needs to be in relation to their body
problems with position in space
unable to perceive ad interpret spatial concepts (up, down, over, under)
topographical disorientation
relationship of one location to another
depth and distance perception problems
inaccurate judgment of direction, distance, and depth
vertical disorientation
- distorted perception of what is vertical
- get cattywhompus
When is vertical disorientation common?
- right after a pt has a stroke
- typically resolves on its own
types of agnosia
- visual
- auditory
- astereognosia
- barognosia
visual agnosia
- person can look at something and can’t say what it is
- can describe everything it does, get pissed
auditory agnosia
- lump sounds that we can distinguish easily
- fire alarm is the same thing as a doorbell or police siren
astereognosia
- I got a pocket full o keys: I can figure out my car key based on feel
- They can’t do that shit
- Complex to take sensory info the brain and figure out what it is
- Turn the lights off and they screwed
barognosia
- pressure
- how much pressure it takes to pick something up
types of apraxia
- ideomotor apraxia
- ideational apraxia
- dressing apraxia
ideomotor apraxia
breakdown between concept and performance
example of ideomotor apraxia
tell them to blow: they can’t do it
- give them bubbles and a wand and they’ll blow dem bubbles
- may be able to do it volitionally but not on their own
ideational apraxia
- complete failure in conceptualization of the task
- they can’t do it when asked or if they want to do it
dressing apraxia
- don’t know where articles of clothing go
- pants on backwards, pants as shirts, shirts as pants, etc
