Question

A L PCA infarct can cause ____________ (difficulty with reading), ______________ hemianopsia, and right _________________.

Answer 1

A L PCA infarct can cause alexia, bilateral hemianopsia, and right expressive aphasia.

Step-by-step explanation:

A L PCA infarct can cause alexia (difficulty with reading), bilateral hemianopsia, and right expressive aphasia.

Alexia is the inability to read or understand written language. It occurs due to damage to the left posterior cerebral artery (L PCA) which supplies blood to the visual processing areas and language centers of the brain. Bilateral hemianopsia refers to the loss of vision in both visual fields.

Expressive aphasia is the loss of the ability to produce language and is associated with damage to Broca's area in the frontal lobe. In the case of an L PCA infarct, damage to the right hemisphere can result in expressive aphasia on the right side.
