Confrontation Naming in Individuals with Temporal Lobe Epilepsy: A Quantitative Analysis of Paraphasic Error Subtypes
American Psychological Association
Although confrontation naming deficits have been observed in dominant temporal lobe epilepsy (DTLE), the relative contribution of impoverished phonologic word retrieval and/or semantic knowledge remains unclear. Analysis of verbal-semantic, phonemic-literal, and combination paraphasias produced during confrontation naming by participants with seizure disorders (52 DTLE; 47 nondominant temporal lobe epilepsy [NDTLE]; 54 psychogenic nonepileptic seizures [PNES]) indicated that the frequency of: (a) verbal-semantic paraphasias was similar across groups, (b) phonemic-literal paraphasias was highest in DTLE, and (c) combination paraphasias was lowest in PNES. Confrontation naming ability was most strongly related to phonemic-literal paraphasia frequency in DTLE and to verbal IQ in both NDTLE and PNES. Greater confrontation naming deficits in DTLE may be attributed to impairments in phonological processing.
