     A case of constructional agraphia was reported for a 61-year-old, right-handed housewife. A lesion in the left parietal area was disclosed by CT scan. The patient presented an europsychological syndrome of Wernickes' aphasia with constructional apraxia. Her disturbance in oral language recovered considerably in about one year and turned to mild conduction aphasia. On the other hand, writing performance (copying, spontaneous writing and dictation) remained grossly disturbed. Moreover, she made mistakes in writing cubes. The writing disorders of the case at this stage were considered as constructional agraphia. Spontaneous writing tasks with ten nouns using kanji (ideograms) and hiragana (phonograms) were compared. The patient made a greater number of errors in kanji tasks than in hiragana. Error patterns in kanji were different from those in hiragana; the former showed errors of similar shapes to the target kanji, the latter comprised no responses or substitution of letters. Although she could not write spontaneously in kanji, she could explain each part of the target kanji word in oral language. This fact proves that the visual image of letters was preserved. The nature of the constructional agraphia in this case is discussed. The case was followed for four years, and disruption of writing performance still persists.
