General Medicine · Neurology: conduction aphasia

Sample item

A patient speaks fluently and understands speech well but cannot repeat sentences and makes frequent phonemic paraphasias. Which structure is disrupted?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Arcuate fasciculus

Conduction aphasia results from damage to the arcuate fasciculus that links the receptive and expressive language areas. Comprehension and fluency are preserved, but repetition is poor with phonemic paraphasias.

Option by option

  • A. Broca area in the inferior frontal gyrus

    Broca area damage gives non-fluent speech with preserved comprehension.

  • B. Wernicke area in the superior temporal gyrus

    Wernicke area damage gives fluent speech with poor comprehension.

  • C. Arcuate fasciculus (correct)

    Correct. A lesion of the connecting white matter tract spares comprehension and fluency but impairs repetition.

  • D. Angular gyrus in the parietal lobe

    Angular gyrus lesions cause alexia with agraphia and Gerstmann features.
