ANSWERS AND EXPLANATIONS

---

A) right arm and face weakness

This answer is incorrect.

This patient is not likely to have weakness, as neither the motor cortex nor the descending motor tracts are directly affected.  (See References)

B) Balint's syndrome

This answer is incorrect.

Balint's syndrome (psychic paralysis of gaze, ocular apraxia, and visual innatention with normal viusal fields) results from damage to bilateral parietal-occipital areas.  (See References)

D) alexia without agraphia

This answer is correct.

This patient has had a stroke in the left occipital cortex, resulting in a right homonymous hemianopsia. The stroke extends rostrally, resulting in damage to the callosal fibers decussating from the right occipital cortex. As a result, this patient will be unable to read anything presented in either visual field (alexia). However, language areas are not directly affected, so the ability to write is preserved (no agraphia).  (See References)

E) Wernicke's aphasia

This answer is incorrect.

Wernicke's aphasia typically localizes to the dominant angular and supramarinal gyri of the temporal lobe. The temporal lobe is not involved in this patient's stroke.  (See References)
