The Rey Auditory Verbal Learning Test (RAVLT) is an episodic memory test that is influenced by demographic variables, such as age, education, and gender. Classic word list learning has also been well documented to be an experimental cognitive paradigm that is very useful for the detection of Alzheimer’s disease. The present study analyzed the performance of healthy elderly subjects on the RAVLT, describing the effects of age, education, and gender. To verify its construct validity, the RAVLT was compared with delayed recall and recognition scores on the Brief Cognitive Screening Battery (DR-BCSB). The sample comprised 183 cognitively healthy elderly subjects from outpatient care units of two university reference centers in Rio de Janeiro and São Paulo, Brazil. All participants were subjected to physical and neurological evaluation and neuropsychological assessment. Pearson’s correlation and Student’s t-test were used to investigate the influence of demographic variables on RAVLT performance. To verify convergent-type construct validity, a correlation between RAVLT and DR-BCSB scores was calculated. These results revealed some normative data and convergent-type construct validity of the RAVLT for a Brazilian elderly population.

    • "Alguns estudos mostram a implicação da escolaridade e da idade. No que diz respeito à idade, à medida que essa aumenta , diminui-se o desempenho geral no teste (Malloy-Diniz et al., 2007; Steinberg et al., 2005; Gale et al., 2007; Knigth et al., 2006; Balthazar et al., 2007; Teruya et al., 2009; Fichman-Chrachat et al., 2010; de Paula et al., 2012). O estudo de Knight et al. (2006) demonstrou declínio consistente e significativo nos escores em função da faixa etária em todas as variáveis do RA- VLT, em um grupo de idosos saudáveis. "

    ABSTRACT: Abstract. This paper aims at reviewing the literature on the use of Rey’s Verbal Auditory Learning Test (RAVLT) with respect to its potential contribution to the differential diagnosis between normal aging and Alzheimer’s disease. We researched articles published in the last ten years, indexed in the databases of PubMed and Lilacs, which were designed to evaluate the use of the RAVLT in the diagnosis of dementia, particularly Alzheimer’s disease. Thirty-seven studies were selected according to the methodology outlined. Seventeen items assessed the utility of the RAVLT test in neuropsychological assessment of de-mentia is usefulness to differentiate AD and normal development and twenty studies investigated the performance of normal elderly on RAVLT or how the factors age, education and gender may influence the performance in the test. Weconclude that the RAVLT is an effective tool to assist in the differential diagnosis between normal and pathological aging. It is necessary, however, further stud-ies on regulation of it to evaluate the different dementia syndromes.

    ABSTRACT: A review of the evidence on cognitive, functional and behavioral assessment for the diagnosis of dementia due to Alzheimer's disease (AD) is presented with revision and broadening of the recommendations on the use of tests and batteries in Brazil for the diagnosis of dementia due to AD. A systematic review of the literature (MEDLINE, LILACS and SCIELO database) was carried out by a panel of experts. Studies on the validation and/or adaptation of tests, scales and batteries for the Brazilian population were analyzed and classified according to level of evidence. There were sufficient data to recommend the IQCODE, DAFS-R, DAD, ADL-Q and Bayer scale for the evaluation of instrumental activities of daily living, and the Katz scale for the assessment of basic activities of daily living. For the evaluation of neuropsychiatric symptoms, the Neuropsychiatric Inventory (NPI) and the CAMDEX were found to be useful, as was the Cornell scale for depression in dementia. The Mini-Mental State Examination has clinical utility as a screening test, as do the multifunctional batteries (CAMCOG-R, ADAS-COG, CERAD and MDRS) for brief evaluations of several cognitive domains. There was sufficient evidence to recommend the CDR scale for clinical and severity assessment of dementia. Tests for Brazilian Portuguese are recommended by cognitive domain based on available data.

    ABSTRACT: Objective: This transversal study aims to evaluate the discriminant validity of the Rey Auditory Verbal Learning Test (RAVLT) by comparing a sample of normal elderly with a patient at the initial stage of Alzheimer’s disease. Methods: Age and educational attainment matched patients at the initial stages of Alzheimer’s disease (n = 35) and normal elderly (n = 35) were submitted to the Rey Auditory Verbal Learning Test, Mini Mental State Examination and the Geriatric Depression Scale. The performance of the two groups was compared using the Mann-Whitney test at each stage of the RAVLT and by ROC analysis the discriminant validity of the test in both populations was evaluated. r esults: The group at the initial stages of Alzheimer’s disease had significantly worse performance in all steps of the RAVLT compared to the control group, and the steps showed good diagnostic power, with areas under the curve ranging between 0.806 and 0.989 (A1 = 0,806; A2 = 0,869; A3 = 0,958; A4 = 0,947; A5 = 0,989; A6 = 0,962; A7 = 0,985; TOTAL = 0,975; LOT = 0,895; REC = 0 ,915). Conclusion: The results suggest that the Rey Auditory Verbal Learning Test is effective for discriminating normal elderly seniors from the ones in early stages of Alzheimer’s disease.
