Abstract
ABSTRACTCognitive aging is dynamic and heterogeneous in elderly, thus adequate tools such as paper-based tests are relevant to describe the cognitive profile of this population.Objective:To describe different paper-based cognitive assessments tests in elderly people stratified by age and education.Methods:A cross-sectional study of 667 elderly (≥60 years) living in the community was conducted. Sociodemographic information was collected. Global cognition was assessed by the Addenbrooke's Cognitive Examination-Revised (ACE-R), Mini Addenbrooke’s Cognitive Examination (M-ACE) and Mini-Mental State Examination (MMSE). The data were analyzed using descriptive statistics, the t-test and Pearson’s Correlation Coefficient.Results:The findings showed a predominance of women (53.8%), mean age of 71.3 (±7.7) years and 3.6 (±3.5) years of education. The best global cognitive performance and cognitive domain assessment scores were found in the group with higher formal educational level. Each year of education was associated with an increase of up to 10% in scores on the M-ACE and MMSE and up to 11% in ACE-R scores. The mean values of the scores varied according to age, where the 60-69 years group had better scores than other age groups. The correlation matrix between the cognitive tests showed that near perfect correlations (r=1) were frequent in the subgroup with higher education.Conclusion:Younger elderly and those with higher educational level had greater global and domain scores. This study describes the scores of elderly for different strata of education and age. In practice, it is important to choose the most suitable screening instrument, considering the characteristics of the elderly.
Highlights
Cognitive aging is dynamic and heterogeneous in elderly, adequate tools such as paper-based tests are relevant to describe the cognitive profile of this population
The present study aims to describe the data of the cognitive performance scores of elderly living in the community for paperbased neuropsychological tests in an elderly population stratified by age and education
The sociodemographic characteristics of the elderly interviewed proved similar to those observed in Brazilian population studies, with a predominance of participants who were women, married, white, retired and with low educational level.[21,22]
Summary
Cognitive aging is dynamic and heterogeneous in elderly, adequate tools such as paper-based tests are relevant to describe the cognitive profile of this population. Objective: To describe different paper-based cognitive assessments tests in elderly people stratified by age and education. The best global cognitive performance and cognitive domain assessment scores were found in the group with higher formal educational level. Conclusion: Younger elderly and those with higher educational level had greater global and domain scores. This study describes the scores of elderly for different strata of education and age. DADOS DESCRITIVOS EM DIFERENTES AVALIAÇÃOES COGNITIVAS EM IDOSOS DA COMUNIDADE: DADOS ESTRATIFICADOS POR IDADE E ESCOLARIDADE RESUMO. Objetivo: Descrever os dados estratificados em idade e escolaridade do desempenho de idosos em diferentes testes cognitivos baseados em papel. Resultados: A maioria dos idosos era mulher (53,8%), as médias foram 71,3 (±7,7) anos para idade e 3,6 (±3,5) anos para escolaridade. O melhor desempenho cognitivo global e nos domínios foram nos idosos com maior nível educacional.
