“…Several studies have shown a gradient of performance reduction according to the severity of cognitive impairment control–MCI–AD group. However, investigation of more specific memory indexes is relatively less explored (Cotta et al, 2011; Strauss et al, 2006). Our results showed differences between RAVLT immediate and delayed recalls on AD patients.…”

Objective: The present study investigates the difference between trials A6 and A7 of the Rey Auditory-Verbal Learning Test (RAVLT) test in three different groups of older adults-normal cognition (Controls), mild cognitive impairment (MCI), and Alzheimer's Dementia (AD). Method: The study comprises 180 subjects 60 years old or more. We compared scores in trials 6 and 7 of list A (A6 and A7) using the Wilcoxon signed ranks test. Subsequently, we computed its difference (A6-A7) and used Mann-Whitney to analyze which groups' differences were more relevant. Results: Comparison analysis showed a significant difference between A6 and A7 trial performance only in the AD group ( p < .01). When we compared these differences between groups, the only significant difference occurred between controls and AD ( p < .01). Conclusions: There is a significant difference in RAVLT trials A6 and A7 in the AD group, but this difference does not appear in the control and the MCI groups. The differences between A6 and A7 trials of RAVLT are restricted to comparing Controls × AD patients. Our study corroborates the instrument's effectiveness for the diagnosis of Alzheimer's dementia.

“…We demonstrated that performance on the Brazilian version of the RAVLT is increasingly impaired when administered to patients with MCI and AD, respectively, relative to matched controls, corroborating reports for other samples from different cultures and backgrounds. 36 , 37 Notwithstanding, sensitivity and other psychometric properties of the RAVLT are beyond the scope of this manuscript and will be addressed in a separate paper. In the present study, we aimed to demonstrate that a specific word with emotional weight (mother) included in the latest version of the list was associated with the Von Restorff effect, changing the traditional U-shape of the serial position recall curve into a W-shape.…”

ABSTRACT. The Von Restorff (isolation) effect refers to a stimulus that is more likely to be remembered amongst other stimuli in memory tasks. It has been demonstrated with different age ranges and methodologies. Objective: To investigate: a) the presence of the isolation effect in elders tested with the new Brazilian Portuguese version of the Rey Auditory Verbal Learning Task (RAVLT) in which a word with potential emotional weight (mother) was introduced; b) whether isolation effects persist in memory disorders of different degrees of severity (Mild Cognitive Impairment [MCI]; Alzheimer’s Dementia [AD]). Methods: The RAVLT was administered to 287 consecutive volunteers. Individuals underwent medical and neuropsychological evaluation and were further sub-grouped into normal controls (n=114), MCI (n=87) and AD (n=86) patients. One-way analysis of variance (ANOVA) and Chi-squared tests were performed. Post-hoc Tukey analysis was conducted to assess significance of group differences. Results: There were significant group effects on the learning curve. A W-shape - instead of the classical U-shape - was found for the serial position curve in all groups. Conclusion: The new Brazilian version of the RAVLT exhibited the Von Restorff effect, where this phenomenon was evident not only in older adults but also patients with MCI and AD, providing further psychometric measures for inter-group analyses.

Characterizing cognitive decline in older adults with MCI over time is important to identify the cognitive profile of those who convert to dementia.Objective:This study examined the two-year cognitive trajectory of elderly adults diagnosed with MCI, from geriatrics and neurology outpatient clinics of a public hospital in Rio de Janeiro.Methods:62 older adults with MCI were submitted to a neuropsychological battery and re-evaluated after two years. The Mann-Whitney U test was employed to assess differences between groups with respect to education, functioning, the Geriatric Depression Scale and diagnosis.Results:24.2% converted to dementia after two years. The group with declines in two or more cognitive functions had a higher conversion rate to dementia than the group with decline in executive functions (EF) only (Z = -2.11, p = .04). The EF decline group had higher scores on the depression scale than both the memory decline group (Z = -1.99, p = .05) and multiple decline group (Z = -2.23, p = .03).Conclusion:The present study found different cognitive decline profiles in elderly adults with MCI and differences between them regarding depressive symptoms and rate of conversion to dementia.
