在纯失读症患者中，尽管说话、拼写和写作几乎正常，但阅读能力却受到了损害。我们研究了一名右撇子，患有纯失读症，但没有偏盲。他较难阅读较长的单词(词长效应)，但在语音或语义分析方面没有选择性阅读障碍。临床-CT对照研究表明：(1)左侧大脑半球视觉通路起源于或靠近左侧枕颞回或颞下回；(2)左侧脑室后角下方右侧大脑半球突起的相关纤维，在升至左侧大脑半球语言区之前。
In pure alexia, reading is impaired despite almost normal speech, spelling, and writing. We studied a righthanded man with pure alexia, but no hemianopia. He had more difficulty reading longer words (word-length effect), but had no selective reading impairment in phonologic or semantic analysis. Clinical-CT correlation suggests that (1) left hemisphere visual pathways crucial for reading arise from or pass close to the left occipitotemporal or inferior temporal gyrus, and (2) relevant transcallosal fibers from the right hemisphere course inferior to the posterior horn of the left lateral ventricle before ascending to left hemisphere language areas.
