Which of the following can be associated with posterior cortical atrophy?

Which of the following can be associated with posterior cortical atrophy?

• A. Frontal lobe dysfunction
• B. Wernicke's aphasia
• C. Visual field deficits
• D. Speech deficits

Answer: (C)

Posterior cortical atrophy (PCA) is a progressive neurodegenerative condition that predominantly affects the posterior portions of the brain, particularly the occipital and parietal lobes. The primary symptoms of PCA are related to visual processing and perceptual skills due to the involvement of these brain regions. Visual field deficits are a hallmark feature of posterior cortical atrophy. Individuals with PCA may experience difficulties with visual perception, including issues such as visual field cuts, problems with recognizing objects, and challenges with spatial awareness. The damage to the occipital lobe, which is responsible for visual processing, leads to these deficits, making this association particularly strong. In contrast, frontal lobe dysfunction, Wernicke's aphasia, and speech deficits are less directly linked to PCA, as these conditions relate more to other regions of the brain and different neurodegenerative processes. Therefore, visual field deficits are the most characteristic and relevant symptom associated with posterior cortical atrophy, underlining why this choice is the correct answer.
