Selective proper name anomia in a patient with asymmetric cortical degeneration

Abstract

All cases of selective anomic deficit for proper names described until now are a consequence of focal cerebral lesions. In the present paper, we report the case of a patient, AF, with a deficient access to proper names of persons and normal access to common names probably subsumed by a degenerative process of the left cerebral hemisphere. MRI evidenced an atrophy of the left temporal lobe and SPECT highlighted hypoperfusion of the left hemisphere. Neuropsychological examination documented a deficient production of proper names belonging to famous personalities both on visual presentation and verbal definition. Moreover, on verbal fluency tasks, AF was poor for the categories of famous peoples and some commercial articles. Finally AF was errorless in a proper name comprehension task.
