The observed speech disorder in these patients is a characteristic entity related to dysfunction of speech expression and may be attributable to damage of not only the AF but also a number of fibres that are related to dysarthria, cognitive and emotional impairments and pyramidal/extra-pyramidal symptoms.

The purpose of this study is to investigate the factors using objective methods relation to the improvement, recovery process and the mechanism of the disorder of acquired childhood aphasia ACA with the localized lesions of the brain. We use the regularized scale of the Standard Language Test of Aphasia SLTA as an index. Eight ACA patients with localized lesions of the posterior part of the left brain were compared with adult aphasic patients with almost same lesions about the recovery level and process. As results, ACA patients with cerebro vascular artery disease and trauma showed higher recovery level than those with infection. In three factors result from factor analysis, comprehension improved at first, then speech, and writing improved. Patients with ACA showed faster and higher recovery level than adult aphasics. Though the recovery level is high, the improvement was limited, and the scores of oral commands, sentence repetition, and Kanji writing were significantly lower than those of controls as well as the adult aphasic patients. The data from another cognitive neuropsychological tests suggest the possibility that the phonological and semantic disorder is likely to affect the limited improvement.

A case of pediatric acquired dyslexia/dysgraphia (PAD) without aphasia is reported here. A one-year-old, right-handed boy with Moyamoya disease was subjected to neuropsychological (NP) and cognitive neuropsychological (CNP) tests concerning dyslexia/ dysgraphia, and his case was compared to cases of PAD with aphasia and to cases of developmentaldyslexia.InthecomparisonwithcasesofPADwithaphasia,thepresentcase characteristicallycombinedwithvisual-memoryimpairment.Inthecomparisonwithcases of developmental dyslexia, his impaired Kana reading and writing was preferentially impaired, although cases with developmental dyslexia would usually show impaired Kanji 医療法人啓佑会 KIDS*FIRST 1) ：〒700-0817 岡山市北区弓之町 15-32 LD・Dyslexia センター 2) ：〒272-0033 千葉県市川市市川南 3-1-1-315 筑波大学大学院人間総合科学研究科 3) ：〒305-8574 茨城県つくば市天王台 1-1-1 独立行政法人国立病院機構東名古屋病院リハビリテーション部 4) ：〒465-8620 名古屋市名東区梅森坂 5-101
