In pure alexia, acquired inability to read contrasts with normal speech and handwriting. Rare cases of right hemisphere lesions causing this syndrome are usually attributed to right hemisphere dominance for language. After infarction of the right occipital lobe and thalamus, a fully right-handed man became alexia, but language and spontaneous and dictated writing were intact. Left hemispatial neglect and constructional disturbances were marked, and we suggest that pure alexia was mimicked by the impairment in visuospatial perception. Injury of the nondominant hemisphere and thalamus together may have been important in causing these deficits.
在纯失读症中，后天获得的阅读能力丧失与正常的言语及书写能力形成对比。少数由右侧半球病变导致该综合征的病例通常归因于右侧半球在语言功能上占主导地位。一名惯用右手的男性在右侧枕叶和丘脑梗死之后出现了失读症，但语言能力以及自发书写和听写能力均保持完好。左侧半空间忽视和结构障碍较为明显，我们认为纯失读症是由视觉空间感知受损所模拟的。非优势半球和丘脑共同受损可能在导致这些缺陷方面起到了重要作用。
