Abstract

Prevalence of subjective memory complaints (SMC) in elderly community dwellers (ECD) ranges from 25 to 50%. Some controversy exists over the association between SMC and cognitive status. Objective: We investigated whether a correlation in cognitive performance existed between two different groups according to SMC. Methods: The Mini Mental State Examination (MMSE) and Dementia Rating Scale-Mattis (DRS-Mattis) were applied to two groups: ECD (n=14) with SMC and residents (n=14) of a long-term care facility (LTCF) without SMC. Results: The median age in the ECD group was 81.0 years, and in the LTCF group was 75.0 years. There was a statistically significant difference (p=0.048) between these groups regarding age. Concerning schooling (1-8 or ³9 years), there was no statistically significant difference between the groups (p=0.638). No statistically significant difference between the two groups was found for scores on the cognitive tests. Conclusion: SMC might be related to extrinsic factors other than insipient cognitive decline.

Key words:

Resumo

A prevalência de queixa subjetiva de memória (QSM) em idosos da comunidade (IRC) varia de 25-50%. Controvérsias existem a respeito da associação entre QSM e cognição. Objetivos: Foi investigado se há correlação entre QSM e declínio cognitivo em dois diferentes grupos. Método: Foi aplicado o Mini Exame do Estado Mental (MEEM) e a Escala de Avaliação de Demência Mattis (DRS-Mattis) em dois grupos de idosos: IRC (n=14) que apresentaram QSM e residentes (n=14) de uma instituição de longa permanência (ILP) sem QSM. Resultados: A mediana de idade do grupo "IRC" foi de 81,0 anos e a do grupo "ILP" foi de 75,0. Houve diferença estatisticamente significante (p=0,048) entre eles, considerando a idade. Não houve esta diferença (p=0,638) na distribuição dos indivíduos quando analisada a escolaridade (1-8 ou ³9 anos). Considerando-se os escores dos instrumentos cognitivos, não houve diferença estatisticamente significante entre grupos. Conclusões: QSM pode estar relacionada a outros fatores em idosos, e não somente à presença de declínio cognitivo.
