Confrontation Naming Errors in Alzheimer's Disease

Abstract

Background/Aims: Impairment in visual interpretation, semantic conception, or word retrieval may contribute to the naming errors identified in the Boston Naming Test (BNT). We investigated the possible cognitive mechanism of the naming difficulty in Alzheimer's disease (AD) by analyzing the error patterns presented in the BNT. Methods: The Chinese version of the 30-item BNT (BNT-30) was performed on 115 normal control (NC) subjects and 104 mild-to-moderate AD patients. Accurate rates after semantic and phonemic cues were analyzed. The frequencies of 7 types of error patterns in the AD patients and the NC subjects were compared. Results: The accurate rate after semantic cues was significantly lower in the AD than in the NC groups, but phonemic cues were more helpful than semantic cues to achieve accurate naming in both groups. The AD patients made more errors in all error patterns. Particularly, the frequency of nonresponse errors (n = 806) in the AD group significantly exceeded that in the NC group (n = 382). However, the distribution of the error patterns did not differ between the two groups. Conclusion: Naming difficulties in AD might be attributed to progressive semantic knowledge degradation. The AD and the NC groups differ quantitatively but not qualitatively in the error patterns in confrontation naming.

Validation of the Cross-Linguistic Naming Test: A naming test for different cultures? A preliminary study in the Spanish population

“…The results have shown that individuals with dementia scored lower than those without dementia on the CLNT and BNT. This finding is consistent with the symptoms of anomia frequently found in the patients with dementia using the BNT (Bayles, Tomoeda, & Trosset, 1992;Lin et al, 2014;Salmon & Bondi, 2009), as well as with the results found in other studies using diverse naming tests (Brouillette et al, 2011;Goldman et al, 2001;Nebreda et al, 2010;Vigliecca, Aleman, & Jaime, 2007). With regard to the possible influence of age and education on the naming tests, we observed that, despite the low education of the control group, their score on the naming tests is similar to the score of the SMC group.…”

Remembering a name: Neuropsychological validity studies and a computer proposal for detection of anomia

“…To this end, previous findings about CNT were reviewed, [42][43][44][45][46] particularly those regarding the type of performance errors (see articles). [47][48][49] We make available the CACNE as a free CNT to be tested using researchers' particular samples and objectives.…”

The Deterioration of Semantic Networks in Alzheimer’s Disease

“…Several studies suggest that the pattern is similar for healthy, MCI, and AD groups and that they only differ quantitatively in the number of errors and non-response errors, but not qualitatively. This, added to the fact that AD patients can improve their performance by using phonological clues, suggests that the semantic network might be preserved longer than thought as the information can still be accessed, and the disruption only occurs at later stages, when the non-response errors are more common (29,30).…”
