Alexia without agraphia is readily recognized in its pure (without other neurologic findings) but rare form. However, this deficit is more common when associated with other behavioral disturbances that result from trauma or cerebral infarction to the posterior cerebral hemispheres. Two cases presented with alexia without agraphia following infarction within the posterior cerebral artery territory. Because of initial confusion and disorientation the patients were diagnosed as demented and unsuitable for rehabilitation. Both subjects had a visual field deficit and color agnosia. Prosopagnosia, simultanagnosia, and ataxia of visual-motor control were also present. The second case was unusual because of pure word blindness associated with a right occipital lobe lesion. Only a few such cases have been reported in the literature worldwide. This paper demonstrates that careful delineation of cognitive deficits permits greater understanding of functional disorders with improved rehabilitation outcome.
纯失读不伴失写症（无其他神经学表现）虽易于识别但其形式罕见。然而，当这种缺陷与因后大脑半球创伤或脑梗死导致的其他行为障碍相关时则更为常见。有两例在大脑后动脉区域梗死之后出现了纯失读不伴失写症。由于最初的意识模糊和定向障碍，这两名患者被诊断为痴呆且不适合康复治疗。两名患者均有视野缺损和颜色失认症。同时还存在面孔失认症、同时性失认症以及视觉运动控制共济失调。第二例患者情况特殊，因为其纯单词盲与右侧枕叶病变相关。全球文献中仅报道过少数此类病例。本文表明，仔细界定认知缺陷有助于更深入理解功能障碍并改善康复效果。
