A study of patient who had alexia without agraphia.

Word blindness and an aphasic writing difficulty are found, not infrequently, when disease of the left occipital lobe has extended anteriorly into the parietal and temporal areas. A less common clinical phenomenon is word blindness with unimpaired writing. Geschwind (1965) analysed personal and previously reported patients and suggested as a cause a particular type of cerebral disconnection, which was in accord with the postulates of other authors. The anatomical basis for the clinical syndrome was given as lesions in the left (dominant) occipital lobe and the splenium of the corpus callosum with an intact left supramarginal gyrus. A clinical, psychological, and anatomical study is presented here which supports this localization.
