What type of deficits can be caused by a stroke in the area supplied by the Posterior Cerebral Artery?

The area supplied by the Posterior Cerebral Artery (PCA) is crucial in understanding the specific neurological deficits that can arise from a stroke in that region. The PCA primarily supplies blood to the occipital lobes and the inferior parts of the temporal lobes, which are key regions for visual processing and awareness.

When a stroke occurs in the territory of the PCA, one of the hallmark deficits is contralateral hemianopia, which is a visual field loss affecting one side of the visual field. This is directly related to the function of the occipital lobe, where processing of visual stimuli occurs. Such visual deficits significantly impact daily activities and overall quality of life, as the individual may be unaware of objects or activities on the affected side.

Additionally, sensory loss can occur due to the involvement of the somatosensory representations in the parietal lobe, which may share vascular supply with the PCA. Thus, patients may experience difficulties in sensation, affecting their ability to perceive touch, temperature, and pain.

Other options provided in the question outline deficits more commonly associated with strokes affecting different regions of the brain. For example, neglect and ataxia are generally linked to strokes impacting the right hemisphere's parietal l
