Abstract
The subject was a 9-year-old girl with aphasia caused by occlusion of the left middle cerebral artery. Linguistic condition was near mutism soon after onset of disease at the age of 4 years 4 months. She recovered early from aphasia and entered primary school, but had difficulty in learning Kana letters.
Reading tended to be inferior to writing. When she was 8 years 1 month, her verbal and performance IQ statistics were normal on the WISC. She also had no difficuety in speech or visual perception.
Although we have continued therapy for three years, the subject's reading and writing difficulty are still observed at present. The lesion that extended to the regions of the left angular gyrus is belived to be affecting her learning ability in reading and writing.
