Abstract

The lesion of the global aphasia often involves both Broca's and Wernicke's speech area, and is shown as broad lesion in the Brain CT However, practically there were several reports about the Brain CT findings of the global aphasia, which suggested atypical patterns that did not involve both language centers, simultaneously. Therefore we subdivided the patterns of Brain CT finding of the 17 global aphasic patients into 4 subtypes according to whether or not the cortical language area was involved. We obtained the following results; 1. Type A : Involvement of the both language areas : 9 cases (53%) 2. Type B : Involvement of only Broca's area with sparing of Wernicke's area : 3 cases(17%) 3. Type C : Involvement of only Wernicke's area with sparing of Broca's area : 1 case (6%) 4. Type D : Involvement only of subcortical area with sparing of cortical language areas : 4 cases (24%)
