Causes
Conduction aphasia is caused by damage in the language-dominant hemisphere (the left hemisphere in most individuals). Lesions in the language centers (and connections between) have been identified as potential inducers for conduction aphasia (and other language disorders, in general). Specifically, patterns of damage in conduction aphasia patients have been observed to cluster in the posterior and inferior temporal lobe, and in the parieto-temporal junction.
The brain damage causing conduction aphasia is often from a stroke, which can produce both localized and widespread damage. Traumatic brain injury and tumors can also lead to localized lesioning, with potential to cause conduction aphasia.
