Q

What is the difference between Homonymous Hemianopsia and Unilateral neglect?

A

a. damage to optic track
b. visual field/eyes are completely in tact, but cant usuallysee LEFT side; in attention to one side. Happens more when its on the R. side of Brain

Q

What is Asterognosis?

A

-inability to “see” with our hands (can’t recognize objects in our hands by using fine motor with closed eyes, rely on vision)

17
Q

What is Asomatognosia

A

-severe loss of BODY SCHEME. Usually evaluated by having client point to different body parts on command or by imitation.

18
Q

What is Apraxia

A

the inability to perform purposeful movement despite normal motor power, and coordination.

19
Q

Describe:

  1. ideational
  2. ideomotor
  3. constructional
  4. dressing
A
  1. errors in content of task (ex. uses a screwdriver as a knife
  2. can’t perform a motor act on command (ex. if you tell them to walk across the room, they are confused)
  3. cant copy/construct a design (ex. load a dishwasher)
  4. trouble dressing (ex. wear pants on arms)
20
Q

What is Proprioception?

A

-the sense that tells us where we are in space, awareness of position in relation to environment and to other body parts

21
Q

What are some mental abilities you need to have when dressing?

A
  • concentration
  • memory
  • problem solving
  • spacial relationships
  • equilibrium and righting reactions
22
Q

What are some physical abilities needed to dress?

A
  • weight shift
  • trunk rotation
  • head alignment
  • motor planning
23
Q

**Some deficits with Homonymous Hemianopsia?

A

-throwing/catching ball
-pouring water into a cup
stepping off a step

24
Q

(Not that important) What is Heteronymous Hemianopsia?

A

-a loss of vision in either or both “nasal halves” (inside of eye) or both “temporal halves” (outside)

25
Q

Signs/Symptoms of Hemianopsia?

A
  • bumps into things
  • tilts head to observe objects
  • loses place while reading
  • startled by objects that”suddenly” appear
26
Q

Are people aware that they have difficulty when they have Unilateral Neglect? Which side is usually neglected?

A

No; often only dress half of body, because they are not aware of it
-the left side because there is a lesion in the RIGHT-frontal parietal lobe

27
Q

Treatment strategies for Unilateral Neglect

A
  • encourage eye and head movements to neglected side

- help patient to regularly look over to their neglected field
