ABSTRACT
Dysnomia is typically assessed during neuropsychological evaluation through visual confrontation naming. Responsive naming to description, however, has been shown to have a more distributed representation in both fMRI and cortical stimulation studies. While naming deficits are common in dementia, the relative sensitivity of visual confrontation versus auditory responsive naming has not been directly investigated. The current study compared visual confrontation naming and auditory responsive naming in a dementia sample of mixed etiologies to examine patterns of performance across these naming tasks. A total of 50 patients with dementia of various etiologies were administered visual confrontation naming and auditory responsive naming tasks using stimuli that were matched in overall word frequency. Patients performed significantly worse on auditory responsive naming than visual confrontation naming. Additionally, patients with mixed Alzheimer's disease/vascular dementia performed more poorly on auditory responsive naming than did patients with probable Alzheimer's disease, although no group differences were seen on the visual confrontation naming task. Auditory responsive naming correlated with a larger number of neuropsychological tests of executive function than did visual confrontation naming. Auditory responsive naming appears to be more sensitive to effects of increased of lesion burden compared to visual confrontation naming. We believe that this reflects more widespread topographical distribution of auditory naming sites within the temporal lobe, but may also reflect the contributions of working memory and cognitive flexibility to performance.
