Abstract
- Pure word deafness is a cluucal syndrome included among the aphasias and is marked by complete deafness of sudden onset with conserved ability to understand and read the written word and with no speech disorders. We report the case of 55year-old female in whom pure word deafness developed after episode of stroke. Neuroimaging procedures, that is : computed tomography scan and MRI, revealed the presence of hemorrhagic lesion in right putamen, mainly the white matter of the temporal and parietal lobes and large open schizencephaly in left temporoparietal area. Neurophysiological investigations (electroencephalogram and brainstem auditory evoked potentials) were also studied. It is proposed that pure word deafness which might be caused by a impairment of the language function possibly transferred to the nondominant, right hemisphere due to congenital dominant hemisphere lesion.
