ABSTRACT OBJETIVO: Investigar se a combinação de uma escala de avaliação funcional com um teste cognitivo poderia melhorar a precisão do diagnóstico de demência. MÉTODO: Foram avaliados 30 pacientes com diagnóstico de demência leve a moderada, segundo critérios da CID-10 e DSM-III-R e 46 controles idosos, divididos em grupos segundo seu nível socioeconômico e educacional (alto, médio e baixo). Nos sujeitos foi aplicado o MMSE, e em seus informantes as escalas IQCODE e B-ADL. RESULTADOS: Pela regressão logística, o MMSE isolado classificou corretamente 86,8% dos pacientes e controles (sensibilidade 80% e especificidade 91,3%). A combinação MMSE + IQCODE classificou corretamente 92,1% dos sujeitos (sensibilidade 83,3% e especificidade de 97,8%), e a combinação MMSE + B-ADL classificou corretamente 92,1% dos sujeitos (sensibilidade 86,7% e especificidade 95,7%). CONCLUSÃO: Os resultados sugerem que a combinação de um teste cognitivo a escalas funcionais pode melhorar a detecção de casos leves ou moderados de demência, mesmo em amostras de população heterogênea com relação ao nível sócio-econômico e educacional como a brasileira.

    ABSTRACT: This article presents the results of the translation and cross-cultural adaptation of the Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE) and the test-retest reliability of a version to be used in Brazil. An instrument review committee analyzed the conceptual and item equivalence. In order to analyze semantic equivalences, three translations and three back-translations were performed; a summary version was devised and pre-tested, and a test version elaborated. The Cronbach's +/- coefficient and intraclass correlation coefficient (ICC) were used to measure the internal consistency and test-retest reliability, respectively. Of the 169 informants assessed, 97 were retested. A Cronbach's +/- of 0.94 and an ICC of 0.92 were found. The reliability levels lead to the conclusion that the IQCODE-BR version is easy to comprehend. Satisfactory equivalence to the original version was observed.

    ABSTRACT: To determine the diagnostic accuracy of the Mini-Mental State Examination combined to the Informant Questionnaire on Cognitive Decline in the Elderly for the identification of mild cognitive impairment. 191 elderly subjects were assessed with the Mini-Mental State Examination, and their informants were assessed with the Informant Questionnaire on Cognitive Decline in the Elderly. Subjects were divided into three groups according to their cognitive state (controls: n = 67, mild cognitive impairment: n = 65 and dementia: n = 59), which was ascertained by clinical and neuropsychological evaluation. The diagnostic accuracy of each test in the discrimination of diagnostic groups (mild cognitive impairment vs. controls, mild cognitive impairment vs. dementia and dementia vs. controls) was examined with the aid of ROC curves. We additionally verified if the combination of both tests would increase diagnostic accuracy for mild cognitive impairment and control identification. The combination of the Mini-Mental State Examination and the Informant Questionnaire on Cognitive Decline in the Elderly scores did not increase the Mini-Mental State Examination diagnostic accuracy in the identification of patients with mild cognitive impairment. The present data do not warrant the combination of the Mini-Mental State Examination and the Informant Questionnaire on Cognitive Decline in the Elderly as a sufficient diagnostic tool in the diagnostic screening for mild cognitive impairment.
