On presentation, she is found to be awake but does not follow directions or respond to questions. She is able to speak and produces a fluent string of nonsensical words and sounds. She does not appear to be bothered by her deficits. Subsequent neurologic exam finds that the patient is unable to comprehend any instructions and is also unable to repeat phrases. CT scan reveals an acute stroke to her left hemisphere. Damage to which of the following structures would be most likely to result in this pattern of deficits?? A: Arcuate fasciculus, B: Inferior frontal gyrus, C: Precentral gyrus, D: Superior temporal gyrus, E: Watershed zone,  <response>: This is a clinical vignette describing an elderly woman with acute onset of fluent aphasia and inability to follow commands after a left hemisphere stroke. The deficits indicate damage to language areas in the dominant left hemisphere. The arcuate fasciculus is a white matter tract connecting Wernickes and Brocas language areas, damage would cause conduction aphasia. The precentral gyrus contains the primary motor cortex, damage causes contralateral weakness. The watershed zones are border zones between major cerebral artery distributions, damage causes variable deficits. Fluent aphasia with inability to comprehend or repeat phrases localizes to Wernickes area in the posterior superior temporal gyrus. This processes language comprehension. Damage here would cause fluent aphasia with poor comprehension, as described.D: Superior temporal gyrus
