Abstract

The classical view of aphasia suggests that conduction aphasia results from disconnection between the anterior and posterior language areas. Several recent reports have challenged this claim suggesting that impaired repetition – the hallmark symptom of conduction aphasia – is associated with damaged gray matter in the left parietal lobe. This study examined the critical lesion location associated with impaired repetition in 44 acute left hemisphere stroke patients. We found that damage to the posterior portion of the left arcuate fasciculus is the best neuroanatomical predictor of impaired repetition. These results support the classical view of conduction aphasia as a disconnection syndrome.
