Intact sensation
What part of the brain is responsible for perception?
Parietal lobe
What infarcts can cause perceptual dysfunction?
ACA, MCA, or PCA

Deficits may increase risk of injury
May impair motor function
Impacts motor learning
Impact prognosis of care

Cannot carry out simple tasks
Difficulty shifting between tasks
Cannot follow one step commands

What is visual discrimination?

Unilateral special neglect (on the left)
How can you test unilateral spatial neglect?
Albert’s cancellation test (drawing lines)
Draw an item
Point to body parts
What are some management strategies for unilateral spatial neglect?
Have a watch beep on affected side
Have a fan blow on them on affected side
Scanning training
Anosognosia
Inability to have awareness of deficits
What are some management strategies for visual discrimination?
Visual scanning
Slowing down
Amplify stimulation (tape on edge of steps)
