Description

<p>　This article shows the author’s 40 years’ clinical practice for patients with aphasia.</p><p>　Poststroke aphasics were tested with the standard language test of aphasia （SLTA）, and following results were obtained</p><p>　　1）　 The word repetition was disturbed more frequently in the aphasia due to cerebral infarction than in that due to cerebral hemorrhage.</p><p>　　2）　 The word repetition was disturbed by cortical lesions involving the left perisylvian region, but not by deep lesions or atrophic cortical sulci.</p><p>　　3）　 The overall severity of aphasia was estimated with the principal component analysis.　Aphasic symptoms were severer in the aphasics with word repetition disturbance than in those without word repetition disturbance.</p><p>　　The repetition test, containing three components（ nonword, word, sentence） was applied in poststroke aphasics.　The maximal number of repeated syllables were compared among these three components.</p><p>　　Word repetition was easier than nonword repetition in all 23 aphasics.　Furthermore, sentence repetition was easier in 9 of 23 aphasics.　These 9 had better word repetition ability.</p><p>　　From the above mentioned results, the author proposed a schema of repetition, which postulates a parallel language processing－phonological, lexicosemantic, and syntactic processings.</p><p>　　Furthermore, the author proposed “10 maxims” regarding clinical characteristics of aphasia in stroke briefly, and the subjective report by an aphasic patient was presented.</p><p>　　Finally, the author commented on some controversies in aphasiology.</p>
