Test 2 Flashcards
Which hemisphere damage would most likely lead to perceptual impair?
right
gnosis
knowledge or knowing
agnosia
loss of ability to recognize sensory input
visual agnosia
inability to recognize familiar people and objects
(visual system is intact)
parietal lobe
Prosopagnosia
cannot ID familiar faces or detect differences via facial Mm
L hemisphere
“all people with mole are the same”
visual spatial inattention
Client has decreased awareness of body and spatial environments on side contralateral to cerebral lesion
difficulty focusing visual attention on self-care tasks
right-left discrimination
inability to “know” R from L
L cerebral hemisphere
visual-spatial perceptual disorder
Topographical orientation – up/down, left/right
Position in space dysfunction - up/down/top/bottom
Depth perception
Compensatory intervention for visual agnosia
use other senses
increased awareness of limitation
teach location and spatial cues
tactile agnosia
astreognosis
inability to recognize familiar objects with hands
Ahyognosia
inability to discriminate between different types of materials by touch alone
Amorphagnosia
inability to discriminate between different forms by touch alone (triangle, square, circle, rectangle)
agraphesthesia
inability to recognize letters being drawn in hand
unilateral neglect syndrome
inattention to contralateral side
sensory or motor neglect
Does client fail to respond because they don’t perceive (sensory neglect) or can’t initiate the movement (motor problem)
Anosognosia-Extensive Neglect Syndrome
Extensive neglect syndrome involving failure to recognize one’s paralyzed limbs as one’s own
R hemisphere
praxis
ability to plan and execute movement
Apraxia
Inability to carry out skilled movement in the presence of intact sensation, movement and coordination
Dyspraxia
Difficulty conceptualizing, planning, organizing and sequencing sensorimotor actions to achieve a goal
Ideational Apraxia
inability to carry out a previously learned task
Ideomotor Apraxia
Involves the loss of kinesthetic memory of motor patterns – The motor plan for specific task may be lost (action)
What should cognitive rehabilitation be?
individualized, pt. goal directed, finally based, promote generalization
process training
Reinforce, strengthen or re-establish previously learned patterns of behavior
Strategy training
Establish new patterns of cognitive activity through compensatory cognitive mechanisms through use of environmental, internal, and external strategies
Compensatory education
educate on cognitive strengths and weaknesses
implemented when re-establishement is not possible
hierarchy of skills
alert > attention (awareness) > memory (awareness) > executive functions (awareness)
Should therapist expect or program for generalization?
program
what are booster shots?
plan for a possible success after fail
full salient cues
overt demonstration
specific salient cues
process cue for self-monitoring
opportunity salient cues
pause
spatial salient cues
use environment
temporal salient cues
timed cues
How to grade activity?
structure, length, environment, complexity
Why make tasks predictable?
helps pt. give meaning to task
Behavioral prosthetic
rubber band to smack wrist
