18
Q

assessment for memory

A

ALAM M N YN BOI

19
Q

compare body image and body scheme

A

body image - visual and mental image of own body\

body scheme - rela of body parts and body to environment

20
Q

unilateral neglect

A

inability to register stim and perception from one side

inferior-posterior parietal lobe

BADLs or IADLs

21
Q

types of unilateral neglect

A

personal - x acknowledge stim on contra side

peripersonal - x stim on space in arm’s reach

extrapersonal - x stim on space more than arm’s reach

motor - failure to move in respond to stim pero normal MMT and ROM

spatial - x stim on contra side of space

sensory - x awareness contra stim

22
Q

anosognosia

A

denial of paretic side

supramarginal gyrus

ask about arm - what happened, how it feels, why cant move

23
Q

somatoagnosia

A

aka autopagnosia or body agnosia

lack of awareness of body parts

dominant parietal lobe

name and pt points body parts

24
Q

R-L discrimination

A

know body parts but not laterality

parietal lobe

point to body parts c laterality

25
Q

finger agnosia

A

inability to identify fingers or inconsistent

angular gyrus of left parietal lobe

name fingers or imitate finger movements

26
Q

figure-ground discrimination

A

distinguish figure from background

parieto-occipital lesions of (R) hemisphere

tissue on white paper or tracing overlapping drawings

27
Q

form discrimination

A

perceive differences in form and shape

parieto-temporo-occipital region of nondominant lobe

pt will pick up and identify object

28
Q

spatial relations disorder

A

perceive the relationship of one object in space to another object or oneself

inferior parietal lobe and parieto-occipital-temporal junction

setting up a table, ask the time

29
Q

position in space

A

perceive and to interpret spatial concepts such as up, down, under, over, in, out, in front of and behind

non-dominant parietal lobe

describe relationship of 2 objects, shoe box and shoe

30
Q

topographical orientation

A

understanding and remembering the relationship of one location to another

right retrosplenial cortex and bilateral parietal lesions

familiar route

31
Q

depth and distance perception

A

inaccurate judgment of direction, distance, and depth

posterior right hemisphere in sup visual association cortices

grasp object and fill glass of water

32
Q

vertical disorientation

A

perception of vertical or maintaining vertical position

non-dominant parietal lobe

hand a cane and revert to vertical

33
Q

agnosia

A

recognize or make sense of incoming information despite intact sensory

34
Q

visual agnosia

A

inability to recognize familiar objects despite normal function

occipito-temporo-parietal association areas

name objects through vision only

35
Q

types of visual agnosia

A

simultagnosia - inability to percieve visual stim as a whole; cant describe whole picture

prosopoagnosia - x recognize faces; voice lng

color agnosia - x color recognition; know color but cannot associate

36
Q

auditory agnosia

A

inability recognize nonspeech sounds or to discriminate

dominant temporal lobe

close eyes and ident sound

37
Q

tactile agnosia

A

aka astereognosis

parieto-temporo-occipital lobe of either hemisphere

close eyes identify object in hand

38
Q

apraxia

A

inability to perform purposeful movements which cannot be accounted for by problem with strength, loss of coordination, impaired sensation, attentional deficits, poor comprehension, or uncooperativeness

39
Q

ideomotor apraxia

A

can do tasks automatically but not upon command

left dominant hemisphere, frontal lesions and post parietal lesions

command pt to do common tasks

40
Q

ideational apraxia

A

cant do purposeful motions either automatic or command

dominant parietal lobe

command pt to do common tasks

41
Q

buccofacial apraxia

A

x purposeful movements with the lips, tongue, cheeks, larynx, and pharynx on command

oral apraxia

frontal lobe, central opercular, anterior insula and first temporal gyrus

perform movements of mouth
