Queston #5902Note

The patient in this question is presenting with symptoms consistent with transcortical sensory aphasia. Transcortical sensory aphasia is similar to Wernicke’s aphasia in that they both exhibit fluent speech and poor comprehension. However, those with transcortical sensory aphasia are able to repeat phrases while those with Wernicke’s cannot. Borderzone infarcts of the MCA-PCA territory (parieto-occipital cortex) can lead to transcortical sensoryaphasia with sparing of the arcuate fasciculus. Transcortical motor aphasia exhibits non-fluent speech, like Broca’s aphasia, except repetition is intact. Transcortical motor aphasia is localized to the ACA/MCA borderzone.
