Abstract:
The lesions on computerized tomography (CT) scan were evaluated in 7 cases of conduction aphasia. On Modified Westem Aphasia Battery (MWAB), all the patients showed fluent aphasia with some paraphasic errors, good comprehension, marked repetition dificit and variable degree of impairment in naming. The three most common lesions on CT scan were supramarginal gyrus and it's white matter, primary auditory cortex, and insular region, which were involved in 6,5,4 cases out of 7 respectively. Of the three lesions, one or variable combinations of them may be the critical structures for repetition difict in these patients, as has been reported in previous studies. In 5 cases Wermicke area was relatively intact and prominent involvement was seen in only 2 cases, which is thought to be associated with relative preseration foaural comprehension in conduction aphasia.
