Abstract

Conduction aphasia, most often caused by damage to the inferior parietal lobe and arcuate fasciculus, is usually characterized by mildly dysfluent speech with frequent phonemic paraphasic errors, impaired repetition, and impaired word finding and naming, but with relatively spared comprehension. We report an 86-year-old right-handed man with conduction aphasia caused by an infarction that damaged his right temporoparietal region. On testing with the Western Aphasia Battery, however, he named objects almost perfectly. To test his naming ability further, we showed him half the items in the Boston Naming Test; we described or defined the other half of the items, but did not show them to the patient. He performed excellently when naming the objects that he could see, but he had difficulty naming the objects that were only described or defined. These observations suggest that visual word naming may be mediated by a network that is somewhat independent of the networks that mediate spontaneous word finding and word finding based on verbal descriptions or definitions.
