Three cases with transcortical sensory aphasia presenting disturbance of word comprehension as a cardinal feature

Abstract

    Three cases with transcortical sensory aphasia were repoted. The language features in these 3 cases included fluent speech, intact repetition, anomia, disturbance in auditory word comprehension, and alexia and agraphia of Japanese idiographic characters (Kanji). The dissociation of poor lexical system from intact phonological and syntactic functions was emphasized. It was suspected that bilateral hemisphere damages play an important role in persistent impairment in auditory word comprehension. In addition, the result of lexical decision task showed the different nature of word comprehension disorder between the first case and the other two cases.
