Neglect Flashcards
What is neglect?
What is it also referred to as?
What does it affect?
What is it?
A disorder of visual attention
Unilateral neglect
One side of the visual field typically the left side
Contralesional as opposed to ipsilesional
What happens with vision?
How is info transferred/transducted?
Then what does it reach?
Light enters the eye
Via the optic nerve
Primary visual cortex (occipital lobe)
Where is the issue with neglect?
How does this typically happen?
Where is it typically?
But what can a stroke affect?
What does it damage?
At a cortical level
Due to a stroke leading damage to the right hemisphere
Parietal lesions
Multiple areas leading to temporal and/or frontal damage
Damage affects network or regions involved in attention
What is dorsal attention network critical for?
Spatial attention
What is the ventral attention network involved in?
Sustained attention and focus
What is typically damaged VAN or DAN?
VAN directly, DAN indirectly
What is homonymous hemianopia?
Visual field is compromised due to visual pathway damage
What is Cancellation?
Miss items on contralesional side e.g. Mark all A’s an individual suffered right hemisphere damage may miss items on the left
What is also used?
Drawing- miss one side of the flower
What is an example of ecological test?
Name objects in the room
What level is cognitive impairment at?
What does priming work for?
Top level
Stimuli in left field in neglect my in hemianopia
How is attentional organised?
What is there evidence of?
What are differences?
What is the effect on memory?
Spatially
Horizontal plane
Hemispheric differences on this plane
If imagining something memories will change depending on spatial perspective in memory
