[A specific disorder of Kanji writing observed in a learning-disabled child--cognitive-psychological and neuropsychological analysis].
We reported a learning-disabled child who demonstrated a specific disorder of Kanji writing. A right-handed 13-year-old boy had showed no abnormality in general intelligence (VIQ114 and PIQ 100 in WISC-R), but could write only 35% of Kanji, which he should have learned six years before. It was necessary to develop a new test battery to detect the symptom which had not been detected using current existing test batteries. In cognitive-psychology, this patient had a retrieval disorder of graphic forms of Kanji. In addition, he showed a disorder in reproduction of complex graphic forms which he was asked to remember. Therefore, it is likely that he had a disorder for both Kanji and complex graphic forms, which is similar to the syndrome of pure agraphia of Kanji in adults.
