The transcortical aphasias These are characterized by intact repetition. Lesions are more varied than with perisylvian aphasias. In addition to the cortical localizations noted, transcortical aphasias may result from subcortical damage. Transcortical motor aphasia Speech is non-fluent, but repetition and comprehension are spared. Lesions are frontal, but spare Broca's area.
Comprehension is impaired, but repetition is normal.
Lesions are posterior, but spare Wernicke's area. Anomic aphasia This can be conceived of as a mild transcortical sensory aphasia, in which comprehension is not affected, but naming is impaired. Repetition is normal. Angular and middle temporal gyrus lesions, as well as other areas, have been implicated. Mixed transcortical aphasia Non-fluent speech, with poor comprehension, but normal repetition.
