What best defines conduction aphasia?

Conduction aphasia is characterized primarily by poor speech repetition capabilities. This specific type of aphasia occurs when there is a disconnection between the language comprehension areas of the brain, such as Broca's and Wernicke's areas, due to damage in the arcuate fasciculus, which connects these regions. Individuals with conduction aphasia can typically understand spoken language and may produce fluent speech, but they struggle significantly with repeating words or phrases accurately. Their speech often contains phonemic paraphasias, where they substitute incorrect sounds in words, highlighting the disconnection in their ability to repeat language as a result of this neural pathway disruption.
