Cognition and Perceptual Impairments categories

~higher order/ executive function


Cognition and perceptual impairments: cognition categories

~attention deficits
~memory impairments


Cognition and perceptual impairments: cognition categories- attention deficits

~Sustained attention
~Selective attention
~Divided attention
~Alternative attention


Cognition and perceptual impairments: cognition categories- memory impairments

~immediate recall
~short- term
~long- term


Cognition and perceptual impairments: Higher-order/ executive function

~Purposive action
~Effective performance



Ability to move



Want to do something so you plan your movement


Purposive action

When you are able to do an action that has a pursue


Cognition and perceptual impairments: Higher-order/ executive function

~Purposive action
~Effective performance


Cognition and perceptual impairments: performance

~body scheme/ body image
~spatial relations impairment


Cognition and perceptual impairments: body scheme/ body image

~Unilateral neglect
~Right-left discrimination
~Finger agnosia


Cognition and perceptual impairments: spatial relations impairment

~Figure-ground discrimination
~Form discrimination
~Spatial relations
~Position in space
~Topographical disorientation
~Depth and distance perception
~Vertical disorientation


Unilateral neglect

~inability to recognize half of your sensory form ½ your body that is not due to a sensory loss
~Usually left side
~pusher- push towards their affected side/ involved side
~The person will not know/ think about the involved side; the body wants to compensate and will push towards the involved side to try and make a new midline



~No insight or awareness of their injury; their brain does not know that they has had the injury
~Usually resolved in the first few months
~Usually more prominent right CVA



~“body agnosia”
~Difficulty with body structure and the relationship with one body part to another; where is my elbow in relationship to my hand


Right-left discrimination

~No clue on R/L
~Have to put some other input besides r/l; tapping, colors, etc


Finger agnosia

~Cant figure out how to use the fingers in a helpful fashion; any fine motor skill is not easy
~Opposition, tying shoes, buttoning, etc


Figure-ground discrimination

~You wont be able to discriminate between lines to find a figure; will just random line and not image
~Cant see where things are because they are all just in the background
~Cant figure out where to grab on a wheelchair


Form discrimination

~Small difference are hard for the pt to discriminate/ separate
~If you open up a drawer- there are lots of long skinny object (pencils, pens, tooth brush, etc) but they all look the same to the stroke pt


Position in space

~Up, down, in, out, below, above- all a jumbled mess to them
~Get on top of the table? Put you hand on top of your knee? Etc
~They cannot understand what that means


Topographical disorientation

~Map- if you want them to gym from their room, they wont remember how they got there (the twists and turns)
~They wont remember how to get to the restroom
~Very common in TBI and stroke; good reason to keep them in therapy


Depth and distance perception

~Can be visual
~Do you where glasses? Near or far sighted?
~Stairs- can look like a slide or a wall; pouring into a glass; curves; potholes/ bumps in the ground


Vertical disorientation

~Everyone is off by 10-15*at first after stroke; not standing straight because they think the world is off tilted
~The world is off to them, so they walk funny/ at an angle
~*like you are walking through the crazy house
~Typically gets better; can occur in either type of stroke (right or left)



~visual agnosia
~auditory agnosia
~tactile/ asterognosis


Visual agnosia

~Has normal eye function/ their eyes work
~They have problems naming the object when they just looking at it
~If they can hold it, they can name it right away
~Just can’t process the visual pathways to say what it is


Auditory agnosia

~They can still hear, but is a sound has a similar sound, it sound the same
~Inability to recognize/ decipher the sounds
~Bark and lightening; cell phone and an ambulance going down the street, voices will probably sounds similar
~Typically have other processing issues


Tactile/ astereognosis

Cant tell you what it is when it is in your hand without looking at it





Ideomotor apraxia

~Breakdown btw concept and performance
~They can do the task but they cannot do the task when asked
~Can brush their teeth without thinking, but if you ask them to do it, they cant
~Can get it form an idea to a motor
~You can sometimes trick them into doing it (if you tell them to stand, they cant, but if you try and get them to get a drink of water, they will easily stand up)
~Also tend to perseverate (motor or verbal)- yes, yes, yes, yes or they keep doing the same action over and over again


Ideational apraxia

~A complete failure of the conceptionalization of the task
~Cant even do the task
~Have no idea on how to put the tasks together to walk, stand up, roll over, etc
