Infarcts of the inferior division of the right middle cerebral artery: mirror image of Wernicke's aphasia.

We searched the Stroke Data Bank and personal files to find patients with CT-documented infarcts in the territory of the inferior division of the right middle cerebral artery. The most common findings among the 10 patients were left hemianopia, left visual neglect, and constructional apraxia (4 of 5 tested). Five patients had an agitated confusional state that was characterized by hyperactivity, restlessness, and easy distractibility. Motor and sensory abnormalities were not severe or persistent. The most common cause was cardiogenic embolism.
