纯失读症是在没有其他语言缺陷的情况下的选择性阅读障碍，是以前识字者脑损伤的结果。一个多世纪以来，这种综合症一直引起研究人员的兴趣，并且是获得性阅读障碍中研究最多的一种。过去 40 年来，纯失读症在认知神经心理学的框架内得到了广泛的研究，但该综合征作为一种临床实体，早于认知神经心理学的推理方法出现。它基于临床医生对患者一系列违反直觉且相对罕见但始终观察到的行为的经验概括。然而，已经提出了不同的关键特征集来定义这种疾病。过去120年来，一系列具有相似但不完全相同的指涉对象的名称表明了这一点，例如，无失写症的失读症、不可知性失读症、词形失读症、言语失读症、整体失读症、单词盲、逐字母（LBL）阅读、逐字母阅读障碍和拼写阅读障碍。
Pure alexia is a selective impairment of reading in the absence of other language deficits and occurs as a consequence of brain injury in previously literate individuals. The syndrome has intrigued researchers for well over a century and is the most studied of the acquired reading disorders. Pure alexia has been extensively investigated over the last 40 years within the framework of cognitive neuropsychology, but the syndrome, as a clinical entity, much predates the inferential methodology of cognitive neuropsychology. It is based on empirical generalizations by clinicians of a counterintuitive and relatively infrequent but, nonetheless, consistently observed set of behaviours in patients. However, different sets of critical features have been proposed to define the disorder. This is indicated by the range of names with similar but not identical referents with which the syndrome has been labelled over the last 120 years, eg, alexia without agraphia, agnosic alexia, word form dyslexia, verbal alexia, global alexia, word blindness, letter-byletter (LBL) reading, letter-by-letter dyslexia, and spelling dyslexia.
