RESUMO -Modificações no mini-exame do estado mental (MEM) foram sugeridas anteriormente em nosso meio. Neste artigo relatamos sugestões para aplicação uniforme deste instrumento. Método: Avaliamos 433 indivíduos saudáveis sem queixas de memória através do MEM tendo seu desempenho sido avaliado quanto às variáveis demográficas. As modificações propostas foram detalhadamente descritas. Resultados: A escolaridade foi o principal fator que influenciou o desempenho dos indivíduos. Na análise de variância entre os grupos de escolaridade obtivemos F(4,425)=100,45, p<0,0001. Os escores medianos por escolaridade foram: para analfabetos, 20; para idade de 1 a 4 anos, 25; de 5 a 8 anos, 26,5; de 9 a 11 anos, 28; para indivíduos com escolaridade superior a 11 anos, 29. Conclusão: Sugerimos o uso desta versão para uniformização dos resultados em nosso meio. Sua aplicabilidade revelou-se boa para ambientes hospitalar, ambulatorial e para estudo populacionais.PALAVRAS-CHAVE: mini-exame do estado mental, testes de rastreio, educação, ambiente domiciliar, ambiente hospitalar.Suggestions for utilization of the mini-mental state examination in Brazil Suggestions for utilization of the mini-mental state examination in Brazil Suggestions for utilization of the mini-mental state examination in Brazil Suggestions for utilization of the mini-mental state examination in Brazil Suggestions for utilization of the mini-mental state examination in Brazil ABSTRACT -Mini-metal state examination (MMSE) is a screening test to detect cognitive impairment. The objectives of the present study are to describe some adaptations for use of MMSE in Brazil and to propose rules for its uniform application. Method: We evaluated 433 healthy subjects using the MMSE and verified the possible influence of demographic variables on total scores. Results: Educational level was the main factor that influenced performance, demonstrated by ANOVA: F(4,425) = 100.45, p<0.0001. The median values for educational groups were: 20 for illiterates; 25 for 1 to 4 yrs; 26.5 for 5 to 8 yrs; 28 for 9 to 11 yrs and 29 for higher levels. Conclusion: The MMSE is an excellent screening instrument and definitive rules are necessary for comparison purposes.
RESUMO -O Mini-Exame do EstadoMental (MEM) foi aplicado em 530 indivíduos, classificados segundo suas idades e escolaridades, para avaliarmos o desempenho dessa população de nosso meto. Constatou-se que, para essa amostra, a idade não interferiu nos escores alcançados. Entretanto, ao comparar quatro níveis de escolaridade (analfabetos, baixa, média e alta) obtivemos diferença estatística significante (p<0,0001) entre os escores, exceto para os indivíduos de baixa e média escolaridade quando comparados entre si. Foram estipulados valores de corte para cada grupo, tomando-se como referência o percentil 5% da porção inferior da curva de distribuição dos valores dos escores. Estes foram: 13 para analfabetos, 18 para baixa e média e 26 para alta escolaridade. Comparando-se estes resultados aos obtidos com o MEM em 94 indivíduos com deficits cognitivos comprovados, utilizando os níveis de corte por nós determinados encontramos: sensibilidade de 82,4% para analfabetos, 75,6% para baixa e média e 80% para alta escolaridade; e especificidade de 97,5% para analfabetos, 96,6% para baixa e média e 95,6% para alta escolaridade. Acreditamos que devam ser utilizados níveis de corte diferenciados para cada escolaridade a fim de que erros diagnósticos possam ser minimizados.

Education level, classified as illiterate, elementary and middle (< 8 years) and high (> 8 years), was a significant predictor of performance (p < 0.0001). Nevertheless, the total scores were not significantly different among the age-groups, young (< or=50 years), middle age 51 to 64 years) and elderly (> or = 65 years). The reference cut-off values were taken from the fifth percent lowest score for each group: illiterate, 13; elementary and middle, 18; and high, 26. When compared to 94 pacients with cognitive impairment, our cut-off values achieved high sensitivity (82.4% for illiterates; 75.6% for elementary and middle; 80% for high) and specificity (97.5% for illiterate; 96.6% for elementary and middle; 95.6% for high educational level). Education-specific reference values for the MMSE are necessary in interpreting individual test results in populations of low educational level, in order to reduce the false positive results.

Um fator de erro importante é a atribuição de distúrbios cognitivos evidentes a razões cult...
OBJECTIVE:To develop and validate a short health literacy assessment tool for Portuguese-speaking adults. METHODS:The Short Assessment of Health Literacy for Portuguesespeaking Adults is an assessment tool which consists of 50 items that assess an individual's ability to correctly pronounce and understand common medical terms. We evaluated the instrument's psychometric properties in a convenience sample of 226 Brazilian older adults. Construct validity was assessed by correlating the tool scores with years of schooling, self-reported literacy, and global cognitive functioning. Discrimination validity was assessed by testing the tool's accuracy in detecting inadequate health literacy, defi ned as failure to fully understand standard medical prescriptions. RESULTS:Moderate to high correlations were found in the assessment of construct validity (Spearman's coeffi cients ranging from 0.63 to 0.76). The instrument showed adequate internal consistency (Cronbach's alpha=0.93) and adequate test-retest reliability (intraclass correlation coeffi cient=0.95). The area under the receiver operating characteristic curve for detection of inadequate health literacy was 0.82. A version consisting of 18 items was tested and showed similar psychometric properties. CONCLUSIONS:The instrument developed showed good validity and reliability in a sample of Brazilian older adults. It can be used in research and clinical settings for screening inadequate health literacy. Health literacy is defi ned as the ability to perform basic reading and numerical tasks required to function in the health care environment.1 There is increasing evidence that health literacy skills are related to important health outcomes, even after adjustments for confounding factors such as education, age, and gender. Inadequate health literacy has been independently associated with lower utilization of preventive services, poor self-management of chronic conditions, low medication adherence, increased hospitalization, and higher death rates. 4 Some population groups are at greater risk for inadequate health literacy including the socioeconomically disadvantaged, immigrants, and older adults. Inadequate health literacy may disproportionately affect the health of older people, not only as a result of generation gap in education, but also because the elderly have more medical conditions, use more health care services, and are more likely to require complex therapeutic regimens. 12Because years of formal schooling alone are not a reliable indicator of health literacy and individuals with lower health literacy skills may try to hide it, it is diffi cult to recognize those patients with inadequate health literacy during routine clinical care.15 Developing RESUMO OBJETIVO: Desenvolver e validar um instrumento breve para avaliação de alfabetismo em saúde na língua portuguesa.

The prevalence of dementia in this study was higher than in other studies, particularly among younger elderly.
Dementia is becoming increasingly prevalent in Latin America, contrasting with stable or declining rates in North America and Europe. This scenario places unprecedented clinical, social, and economic burden upon patients, families, and health systems. The challenges prove particularly pressing for conditions with highly specific diagnostic and management demands, such as frontotemporal dementia. Here we introduce a research and networking initiative designed to tackle these ensuing hurdles, the Multi-partner consortium to expand dementia research in Latin America (ReDLat). First, we present ReDLat's regional research framework, aimed at identifying the unique genetic, social, and economic factors driving the presentation of frontotemporal dementia and Alzheimer's disease in Latin America relative to the US. We describe ongoing ReDLat studies in various fields and ongoing research extensions. Then, we introduce actions coordinated by ReDLat and the Latin America and Caribbean Consortium on Dementia (LAC-CD) to develop culturally appropriate diagnostic tools, regional visibility and capacity building, diplomatic coordination in local priority areas, and a knowledge-to-action framework toward a regional action plan. Together, these research and networking initiatives will help to establish strong cross-national bonds, support the implementation of regional dementia plans, enhance health systems' infrastructure, and increase translational research collaborations across the continent.
