Answer:
C) unilateral spatial neglect
Explanation:
Spatial neglect: The term spatial neglect refers to one of the most common syndromes that follow a stroke, generally to the right side of an individual's brain, hence the individual or person dealing with spatial neglect fails to be aware of people or objects to his or her left.
Unilateral spatial neglect: The unilateral spatial neglect is referred to a complex deficit of attention that occurs following a stroke. It happens due to the damage of frontal lobe, thalamus, or posterior parietal cortex, etc.
