韩国的书面语言是由表意文字（Hanja）和音标文字（hanl）组成的，就像日本由汉字（Kanji）和假名（Kana）组成一样。日语中有脑损伤后表意文字和音标文字分离的报道，但在韩语中很少报道。我们报告了一位64岁的右撇子男性，他在左侧后下颞叶梗塞后表现出失读症和汉字失写症，但保留了韩文阅读和写作。有趣的是，这位病人是汉字专家；40多年来，他一直是汉字书法家。但是，当他面对小学教的65个基本汉字时，他的反应既慢（6.3秒/个字母），也慢（8.8秒/个字母）。在阅读和书写中，正确答对率为81.5%（65个字母中有53个）。患者的表现超过了6个年龄、性别和教育程度相匹配的对照组的平均2sd，他们正确地阅读了65个字母中的64.7个，正确地写了65个字母中的62.5个，反应时间要短得多（阅读1.3秒/个字母，书写4.0秒/个字母）。这些发现支持了这样一种观点，即表意文字和语音文字可以在不同的大脑区域进行调节，韩国患者的汉字失读症伴失写症可能与左后颞下病变有关。
Korean written language is composed of ideogram (Hanja) and phonogram (Hangul), as Japanese consists of Kanji (ideogram) and Kana (phonogram). Dissociation between ideogram and phonogram impairment after brain injury has been reported in Japanese, but few in Korean. We report a 64-yr-old right-handed man who showed alexia with agraphia in Hanja but preserved Hangul reading and writing after a left posterior inferior temporal lobe infarction. Interestingly, the patient was an expert in Hanja; he had been a Hanja calligrapher over 40 yr. However, when presented with 65 basic Chinese letters that are taught in elementary school, his responses were slow both in reading (6.3 sec/letter) and writing (8.8 sec/letter). The rate of correct response was 81.5% (53 out of 65 letters) both in reading and writing. The patient's performances were beyond mean-2SD of those of six age-, sex-, and education-matched controls who correctly read 64.7 out of 65 and wrote 62.5 out of 65 letters with a much shorter reaction time (1.3 sec/letter for reading and 4.0 sec/letter for writing). These findings support the notion that ideogram and phonogram can be mediated in different brain regions and Hanja alexia with agraphia in Korean patients can be associated with a left posterior inferior temporal lesion.
