Abstract

Although anemia in transcortical sensory aphasia (TSA) is usually described as a semantically based deficit (naming and recognition are equally affected), dissociations in naming performance have occasionally been reported. We report a two-part study: in Study 1 the pattern of preserved and impaired language abilities was examined in five patientswith TSA and intact object naming; in Study 2 the neural mechanism(s)underlying preserved visual confrontation naming in TSA was examined. Demographic factors, severity of language deficits, lesion volume andlocation, and cerebral asymmetries of patients with TSA and intact naming (TSA-intact) (n=6) were compared with those of patients with TSA and impaired naming (TSA-impaired) (n=6), anemic aphasia (Anemia) (n=6), and left hemisphere damage without aphasia (Control). The results of Study 1 revealed that all five patients had a relative preservation of oral production (spontaneous speech, repetition, naming and readingaloud), but impaired auditory and written (sentence-level) comprehension. Object/picture naming was significantly better than auditory comprehension of the same targets, and naming was also preserved in tactile and auditory (verbal definitions and non-verbal sounds) modalites, but written naming was impaired. In four patients oral reading showed apattern of phonological dyslexia. The results of Study 2 failed to demonstrate significant differences between the groups with preserved naming (TSA-intact and control) and those with impaired naming (TSA-impaired and anemia) in non-language variables that might explain the selective preservation or impairment of naming. These results are discussed in terms of the functional and anatomical independence of the neuralsystems responsible for object naming and comprehension.
