Which aphasia is fluent with paraphasias, preserved comprehension and reading, but impaired repetition due to arcuate fasciculus damage?

Understanding conduction aphasia involves recognizing a disconnection in the language network rather than a loss of language areas themselves. When the arcuate fasciculus, the pathway linking Wernicke’s area (comprehension) to Broca’s area (production) is damaged, repetition becomes the weak link. The person can produce fluent speech and understands spoken language, and reading is relatively preserved, but repeating spoken words or sentences is impaired. The presence of fluent speech with phonemic or other paraphasias, intact comprehension, and poor repetition is classic for this pattern. This set of features distinguishes it from other aphasias: Wernicke’s aphasia shows fluent speech but poor comprehension; Broca’s aphasia shows nonfluent speech with relatively better comprehension; global aphasia involves widespread deficits across production and understanding, with poor repetition.
