A non-right-handed patient developed alexia without agraphia from a right occipital lobe infarction. An intracarotid amobarbital test showed left hemispheric dominance for speech. The cause of alexia in this patient could not be explained simply by the accepted disconnection hypothesis, which proposes that speech, handedness, and reading functions reside in the same hemisphere. The findings in this patient suggest that his speech function is located on the left, whereas his functions for reading and writing are located in the right hemisphere.
一名非右利手患者因右侧枕叶梗死出现失读症但无失写症。颈动脉内阿米妥试验显示言语功能由左侧半球主导。该患者失读症的病因无法简单地用公认的分离假说解释,该假说认为言语、利手和阅读功能位于同一半球。该患者的研究结果表明,他的言语功能位于左侧,而阅读和书写功能位于右侧半球。
