Conduction aphasia and arcuate fasciculus.

Three patients are presented who developed conduction aphasia after a small infarction almost exclusively confined to the arcuate fasciculus. All of them were diagnosed as conduction aphasia within a week after the stroke and showed a rapid amelioration. On the basis of the 3 patients and conduction aphasics in the literature, the relation between conduction aphasia and the arcuate fasciculus is discussed.
