Background: MCI can be classified as amnestic (aMCI) or non-amnestic (naMCI). Patients with aMCI are at increased risk of developing Alzheimer’s disease (AD). The clinical diagnosis encompasses episodic memory decline with preservation of activities of daily living, in addition to possible changes in other cognitive domains. Nevertheless, there is a lack of studies in the Brazilian population comparing the performance of aMCI on different episodic memory tests. Objectives: This study investigated episodic memory alterations in patients with aMCI and healthy controls (HC) through population-validated tests. Methods: We included 54 individuals, 36 aMCI and 18 HC. The neuropsychological protocol included estimated total IQ [vocabulary and matrix reasoning], Logical Memory (LM), Visual Reproduction (VR) and Rey Auditory Verbal Learning Test (RAVLT). Results: Significant differences were found between the groups in LM delayed recall (p=0.048); Visual Memory immediate recall (p=0.002); Visual Memory delayed recall (p=0.006); RAVLT immediate recall (p=0.19); RAVLT delayed recall (p=0.006) and RAVLT recognition (p=0.001). Conclusions: aMCI patients showed significant cognitive deficits in all episodic memory tests, except for the LM immediate recall. These findings corroborate the international literature and indicate the possibility of identifying differential cognitive alterations in the MCI.

AbstractPerformance of different episodic memory processes in patients with amnestic mild cognitive impairment (aMCI) and mild Alzheimer’s disease (AD) and their anatomical correlates are not completely understood. We evaluated the performance of 48 subjects (17 with aMCI, 15 with mild AD, and 16 controls) on the Rey Auditory Verbal Learning Test (RAVLT). A brain MRI voxel-based morphometry (VBM) analysis was run with the aim of evaluating the correlations between RAVLT and gray matter density. All memory processes were compromised in aMCI and mild AD. Also, the same cerebral structures were involved in all RAVLT stages. Learning and delayed recall were more related to the medial prefrontal cortex and hippocampi, whereas recognition was more related to the thalamic nuclei and caudate nucleus, particularly in the left side. Our findings suggest that these structures may act as a complex functional system and are involved in the acquisition of new information. (JINS, 2010, 16, 205–209.)

Normative data for recognition trial in the Italian RAVLT’s doesn’t exist. Our purpose is to define preliminary Italian norms of the Recognition Trial. Our data analysis is based on a sample of healthy italian subject (N = 397; Male = 166; Female = 231) aged between 52 and 86 (mean age = 69,12). The results show a significant effect of level of education, age, and gender on Rey AVLT Recognition performance. These predictors account respectively for 18.2%, 6.7% and 1.6% of the explained variance. Due to the low size of the increment (1.6%) due to the predictor gender, considering the level of significance associated with it (Sig. F Change = 0.002), we decided to give separate norms for males and females. We also included descriptive statistics concerning the Immediate Recall and Delayed Recall trial of the Rey Word test.

OBJECTIVE: To study prospective and retrospective memory in patients with mild Alzheimer's disease (AD). METHOD: Twenty mild AD and 20 matched normal control subjects were included. Diagnosis of AD was based on DSM-IV and NINCDS-ADRDA criteria, using CDR 1 and MMSE scores from 16 to 24 for mild AD. All subjects underwent retrospective (Rey Auditory Verbal Learning Test, RAVLT) and prospective memory tests (the appointment and belonging subtests of the Rivermead Behavioral Memory Test, RBMT; and two tests made to this study: the clock and the animals test), as well as MMSE, neuropsychological counterproofs, and Cornell Scale for Depression in Dementia. The data was analyzed with Wilcoxon test and Spearman correlation coefficient. RESULTS: AD patients performed worse than controls in prospective and retrospective memory tests, with poorer performance in retrospective memory. There was no correlation between prospective memory and attention, visual perception, executive function, or depression scores. CONCLUSION: Prospective and, in higher degree, retrospective memory are primarily and independently impaired in mild AD.

Background: The study aimed to investigate the relationships between F-18 fluorodeoxyglucose (18F)FDG uptake and neuropsychological assessment in Alzheimer’s disease (AD). Methods: We evaluated 116 subjects with AD according to the NINCDS-ADRDA criteria. All the subjects underwent a brain PET/CT with (18F)FDG, cerebrospinal fluid (CSF) assay, mini-mental state examination (MMSE) and further neuropsychological tests: Rey auditory verbal learning test, immediate recall (RAVLT immediate); Rey auditory verbal learning test, delayed recall (RAVLT, delayed); Rey complex figure test, copy (RCFT, copy); Rey complex figure test, delayed recall (RCFT, delayed); Raven’s colored progressive matrices (RCPM); phonological word fluency test (PWF) and Stroop test. We performed the statistical analysis by using statistical parametric mapping (SPM12; Wellcome Department of Cognitive Neurology, London, UK). Results: A significant relationship has been reported between (18F)FDG uptake and RAVLT immediate test in Brodmann area (BA)37 and BA22 and with RCFT, copy in BA40, and BA7. We did not find any significant relationships with other tests. Conclusion: In the AD population, brain (18F)FDG uptake is moderately related to the neuropsychological assessment, suggesting a limited impact on statistical data analysis of glucose brain metabolism.

Abstract Objective The principal goal of this study was to produce adjusted normative data for European Portuguese native speakers from Portugal on 2 neuropsychological tests widely used to assess learning and memory: the Hopkins Verbal Learning Test-Revised (HVLT-R) and the Rey–Osterrieth Complex Figure Test (ROCF). Method The study included 300 individuals aged 18–92 years (M = 50.4, SD = 21.2), who had educational backgrounds ranging from 3 to 25 years (M = 10.4, SD = 5.2). Results Age, education, and sex were significantly associated with HVLT-R and ROCF performance. These demographic variables accounted for 61% of the variance in HVLT-R total recall, 54% in HVLT-R delayed recall, 18% in HVLT-R recognition, 55% in ROCF copy, and 39% in ROCF immediate recall. Conclusions The normative data are presented as regression-based algorithms to adjust direct and derived test scores for age, education, and sex. This study provides a calculator of normative data derived from the results of the regression models.

We aimed to find the differences in memory capabilities between pornography-addicted and nonaddicted juveniles. We enrolled 30 juveniles (12–16 y) consisting of 15 pornography addiction and 15 nonaddiction subjects. We used Rey Auditory Verbal Learning Test (RAVLT) to measure verbal memory, Rey–Osterrieth Complex Figure Test (ROCFT) for visual memory, along with Trail Making Test A and B (TMT-A and TMT-B) for attention. We found a significant reduction in the RAVLT A6 result of the addiction group (nonaddiction vs addiction: 13.47 ± 2.00 vs 11.67 ± 2.44, MD = −1.80, p=0.04), but not in ROCFT or attention tests. Analysis in sex subgroups yielded no sex-specific difference. We concluded that pornography addiction may be associated with impaired recent verbal memory in juveniles, regardless of sex and without association to attention.

ABSTRACT The low-educated elderly are a vulnerable population in whom studying the role of white matter integrity on memory may provide insights for understanding how memory declines with aging and disease. Methods: Thirty-one participants (22 women), 23 cognitively healthy and eight with cognitive impairment-no dementia, aged 80.4 ± 3.8 years, with 2.2 ± 1.9 years of education, underwent an MRI scan with diffusion tensor imaging (DTI) acquisition. We verified if there were correlations between the performance on the Brief Cognitive Screening Battery (BCSB) and the Rey Auditory Verbal Learning Test (RAVLT) with DTI parameters. Results: The BCSB delayed recall task correlated with frontotemporoparietal connection bundles, with the hippocampal part of the cingulum bilaterally and with the right superior longitudinal fasciculus. The RAVLT learning and delayed recall scores also correlated with the hippocampal part of the cingulum bilaterally. Conclusions: Although preliminary, our study suggests that the integrity of white matter frontotemporoparietal fasciculi seems to play a role in episodic memory performance in the low-educated elderly. This finding opens opportunities to study potential targets for memory decline prevention in vulnerable populations.
