| Abstract | We report a patient with progressive word deafness and foreign accent syndrome. The patient is 70-years-old right-handed female. Although pure tone audiometry is normal, speech audiometry is impaired. Her speech occasionally shows sound errors and omission or misuse of postpositional particles, and is perceived by listeners as foreign. There are not any other cognitive deterioration and aphasia including comprehension of sentences with complex syntax. The most prominent feature of her speech is abnormality of prosody, although abnormality of accent and segmentation of sounds are also apparent. MRI of the brain revealed atrophy of the right superior temporal gyrus and Heschl's gyrus. IMP-SPECT showed bilateral frontotemporoparietal hypoperfusion, particuraly in the right hemisphere. The responsible lesions may be bilateral peri-Sylvius region with an emphasis on the right hemisphere. There would be cases with progressive word deafness and speech disorders as a subtype of progressive aphasia. |
