“…These results are compatible with the hypothesis of a relatively early disorganization of the structure of lexico-semantic knowledge in people with MCI (Dudas et al, 2005;Willers et al, 2008). The outcome is also congruent with the inability of MCI individuals to benefit from category-specific semantic cues in memory tasks (e.g., Curiel et al, 2013) and the proactive interference in active learning of list of items (see Loewenstein and Acevedo, 2005;Crocco et al, 2014).…”

“…17 Although a correlation between naming and cognitive impairment has been observed, [2][3][4][5][6]17 questions remains regarding the validity of the CNT total score for the detection of anomia in some disorders which supposedly have this symptom (see papers). 9,12,18 Considering brain laterality and naming, some new perspectives have emerged (focused mainly on specific brain areas or pathologies), and there is now a substantial body of work about this issue. 12,13,[19][20][21][22][23][24][25][26][27][28] Despite using a different approach to the one employed in the present study, these perspectives aid understanding and encour-age validity studies.…”

There are contradictory results or lack of validity studies concerning the naming function and brain laterality. Although anomia is a frequent symptom of memory impairment, and the most relevant symptom of aphasia, few studies have been conducted to evaluate its validity for detecting patients with left-hemisphere damage (LD), as per the MeSH definition. Objective: To validate a paper-and-pencil confrontation naming test (CNT) according to side of brain injury; to select a valid and reliable abbreviated CNT wherein the effect of demographic variables is minimized; and to use the selected CNT to develop a computer-aided confrontation-naming evaluation (CACNE). Methods: Control data were obtained from 213 healthy participants (HP) aged 15 to 89 years. A subsample of 106 HP was demographically matched to 39 patients with LD and 40 patients with right-hemisphere damage (RD). Anomia definition and CNT cues were considered for the CACNE. Results: Test-retest and inter-rater reliability, internal consistency, and validity for detecting LD were demonstrated. A significant age effect was observed in HP. The CACNE was developed to detect anomia in interaction with environmental interventions. Conclusion: The inconsistencies observed in the CNT studies were probably due to the presence of anomia in almost 50% of the RD patients.

“…While declining performance on typical confrontational naming tasks is evident in Alzheimer's Disease [10], and confrontational naming tasks have been useful in staging more moderate to severe AD [11], such tests have not been useful in reliably detecting differences in preclinical AD or MCI[12, 13] .…”

Connected language is often impaired among people with Alzheimer's Disease (AD), yet little is known about when language difficulties first emerge on the path to a clinical diagnosis. The objective of this study was to determine whether individuals with psychometric (preclinical) evidence of amnestic Mild Cognitive Impairment (MCI) (pMCI) showed deficits in connected language measures. Participants were 39 pMCI and 39 cognitively healthy (CH) adults drawn from the Wisconsin Registry for Alzheimer's Prevention, who were matched for age, literacy, and sex. Participants completed a connected language task in which they described the Cookie Theft picture from the Boston Diagnostic Aphasia Examination. Language samples were analyzed across 3 language domains: content, syntactic complexity, and speech fluency. Paired t-tests were used to compare CH and pMCI groups on all variables, and Cohen's d effect sizes were calculated for each comparison. The CH and pMCI groups differed significantly on measures of content (e.g., CH group produced more semantic units, more unique words and had larger idea density, on average, than the pMCI group). The picture description findings are consistent with previous retrospective studies showing semantic language differences in adults with autopsy-confirmed AD. Given that these comparisons are between cognitively healthy and pMCI individuals (before a clinical MCI diagnosis), these findings may represent subtle language difficulty in spontaneous speech, and may be predictive of larger language changes over time.
