Which artery is associated with visual perceptual and unilateral neglect impairments?

The Middle Cerebral Artery (MCA) is crucial in supplying blood to areas of the brain that handle functions related to visual perception and spatial awareness. When there is a disruption in blood flow through this artery, which often occurs during a stroke, it can lead to significant cognitive and perceptual deficits. One common outcome of damage to the areas supplied by the MCA is unilateral neglect, where individuals may fail to acknowledge stimuli on one side of their body, typically the side opposite to the injury. This is particularly evident in the right hemisphere MCA strokes leading to neglect of the left side.

In addition to unilateral neglect, visual perceptual impairments can also stem from damage to the occipital and parietal lobes that the MCA supplies. Patients may experience difficulties in recognizing objects, faces, or even navigating spaces due to disruptions in the neural pathways responsible for processing these visual cues.

The other arteries listed are less directly associated with these particular impairments. The Anterior Cerebral Artery primarily affects the lower limb function, while the Posterior Cerebral Artery mainly supplies the occipital lobe, which is more linked to visual processing rather than perceptual neglect. The Basilar Artery serves regions associated more with brainstem functions, which
