초록
Alexia can occur with or without minimal impairment of other language abilities although it is usually associated with aphasia. The classical lesion for pure alexia is in the left occipital area and the splenium. We report a case of pure alexia without involvement of the splenium. The results of stepwise assessments revealed that the patient’s capacity for visual analysis was intact, but there were severe difficulties in both lexical and phonological routes for reading. The large lesion in the left temporo-occipital area would be responsible for the symptoms.
Abstract
Alexia can occur with or without minimal impairment of other language abilities although it is usually associated with aphasia. The classical lesion for pure alexia is in the left occipital area and the splenium. We report a case of pure alexia without involvement of the splenium. The results of stepwise assessments revealed that the patient’s capacity for visual analysis was intact, but there were severe difficulties in both lexical and phonological routes for reading. The large lesion in the left temporo-occipital area would be responsible for the symptoms.
