Alexia without agraphia in a left-handed patient with a right occipital lesion.
A left-handed patient who had suffered an ischemic vascular accident in the territory of the right posterior cerebral artery displayed alexia without agraphia. Clinical examination of this alexia revealed semiological characteristics comparable with those observed in cases of left temporo-occipital lesions in right-handed patients. Analysis of these disturbances indicated that they were agnosic in nature. The associated disturbances included problems of visual representation and topographic memory together with an amnesic syndrome.
