33
Q

What is the difference between sensation and perception?

A

sensory (touch, hearing, vision, smell, taste)

36
Q

A
  • problem solving

- memory

37
Q

  • Body scheme and Body Image Impairments
  • Spatial Relationships
  • Agnosias
  • Apraxia
39
Q

Perceptual deficits in general tend to be associated with ________ injuries and tend to be more common with injury to our ______ side.

A
  • parietal

- right

40
Q

What is body image?

A

visual and mental image of ones body

41
Q

What is body scheme?

A
  • postural model of the body (body awareness)
  • includes relationship of body parts to each other and their relationship of the body to the environment (body awareness)
42
Q

One of the most common impairments related to our body scheme/image is ________.

A

unilateral neglect

43
Q

What is unilateral neglect?

A

failure to orient toward, respond to, or report stimuli on the side contralateral to the lesion despite normal sensory, motor, and visual symptoms

44
Q

Unilateral neglect mostly occurs with ___________, ___________ lesions

A

R temporoparietal junction, posterior parietal

45
Q

Why do we usually see unilateral neglect on the R side of the brain?

A
  • The right side of our brain provides perception to both visual sides while the left only provides visual perception to the right side.
  • From this, we can deduce that if we lose the left visual perception, the right can still perceive the right side.
  • If we lose the right, however, there is nothing to make up for the left side that is lost.
46
Q

What are the 2 classifications used for unilateral neglect?

A
  • Modality

- Distribution

47
Q

For modality, what are the 3 types of neglect we can see?

A
  • sensory
  • motor
  • representational
48
Q

What are the 3 senses that are effected with sensory neglect?

A
  • auditory
  • visual
  • tactile
49
Q

What is an example of sensory neglect?

A
  • patient only draws half a house

- patient cant hear family member on left side, even though hearing is fine

50
Q

What is an example of motor neglect?

A

ball thrown at someone and they only lift one arm to catch it even if they have full strength in both arms

51
Q

What is an example of representational neglect?

A

patient internally knows what a clock looks like, but draws all 12 numbers on one side of the clock

52
Q

What is the difference between personal neglect and spatial neglect?

A

Personal Neglect
-lack of exploration or awareness of contralateral side of BODY
Spatial Neglect
-failure to acknowledge stimuli of the contralateral side of space
-can be divided into peripersonal and extrapersonal spatial neglect

53
Q

What is the difference between peripersonal and extrapersonal spatial neglect?

A
  • Peripersonal- spatial neglect within reaching space

- Extrapersonal- spatial neglect in far space

54
Q

What is somatoagnosia and where is it more common?

A

Patient cannot identify when body is in the middle

57

A

Pusher Syndrome

58

A
  • active pushing
  • without
  • passive
60
Q

A

inability to distinguish a figure from the background in which it is embedded

61
Q

What is Spatial Relations Disorder?

Where is the lesion in this disorder?

A
  • inability to perceive relationship of one object in space to another object or to one’s self (distance between)

62
Q

What is position in space disorder?

A
  • decreased ability to perceive and interpret spatial concepts
  • more specific to directional concepts (up, down, left, right)
63
Q

What is topographical disorientation?

A

difficulty perceiving relationships from one location to another in the environment

64
Q

What is depth and distance perception?

A
  • inaccurate judgement of direction, distance, and depth
  • different than spatial relations disorder by looking at more broad environmental cues (such as difficulty negotiating a curb and picking leg up high enough to clear stairs)
65
Q

What is agnosia?

A
  • decreased ability to recognize stimuli despite intact sensory function
  • most commonly associated with damage to temporal lobe
66

What are the 3 types of agnosias?

A
  • visual
  • auditory
  • tactile
67

72
Q

What are the two types of apraxia?

A
  • ideomotor

- ideational

73
Q

What is ideomotor apraxia?

A
  • breakdown between concept (idea) and performance (motor execution)
  • lose the ability to carry out tasks on command (can do it on own though)
  • more common with multiple step commands
74
Q

What is ideational apraxia?

A
  • failure in the conceptualization of the task
  • cant do task on command or own their own
  • have no idea what to do with objects
