Memory complaint scale (MCS): Proposed tool for active systematic search

Escala de queixa de memória (EQM). Proposta de um instrumento para busca ativa e sistematizada

ABSTRACT

Subjective Memory Complaints (SMC) are frequent among adults and elderly and are associated with poor quality of life. The etiology and clinical significance of SMCs are unclear, but these complaints are associated with objective cognitive decline or with depression, anxiety and psychosocial stressors. Biological and physiological brain alterations resembling those in Alzheimer's Disease have been found in SMC. SMC can evolve with different outcomes and represent the initial symptom or a risk factor of dementia. Active systematic search can be useful for early screening of candidates for preventive or therapeutic interventions.

Objective:

To propose a Memory Complaints Scale (MCS) as an instrument for actively searching for memory complaints and to investigate its utility for discriminating demented from cognitively normal elderly.

Methods:

A total of 161 patients from a teaching behavioral neurology outpatient unit of a tertiary hospital were studied. The MCS was used in two ways, by direct application to the patient and by application to the patient's companion. Cognitive tests assessing depression and daily living activities were also applied.

Results:

High Cronbach's alpha coefficients were found for the two application methods. Correlations between the two versions and the other instruments administered for patients grouped by type and severity of dementia were also found.

Conclusion:

The MCS is a useful scale for identifying memory complaints and discriminating demented from cognitively normal elderly. Further studies confirming these findings are warranted.

Key words:
subjective memory complaints; memory; psychometric tests; dementia

RESUMO

Queixa Subjetiva de Memória (QSM) é frequente entre adultos e idosos e está associada a pior qualidade de vida. Etiologia e significado clínico são incertos, sendo associada a perdas cognitivas objetivas ou a depressão, ansiedade e estressores psicossociais. Foram demonstradas alterações biológicas e fisiológicas encefálicas semelhantes às da doença de Alzheimer. Pode ter diferentes desfechos e representar sintoma inicial ou fator de risco para demência. A busca ativa e sistematizada pode ser útil na identificação precoce de pessoas que poderão receber intervenções preventivas ou terapêuticas.

Objetivo:

Propor a Escala de Queixa de Memória (EQM) como um instrumento para a busca de queixa de memória e investigar se é útil para discriminar idosos demenciados de normais.

Métodos:

Foram estudados 161 pacientes de um ambulatório didático de neurologia comportamental de um hospital terciário. A EQM foi utilizada nas duas formas, uma diretamente aplicada ao paciente e a outra aplicada ao acompanhante sobre o paciente. Também foram aplicados testes cognitivos, para depressão e para atividades diárias.

Resultados:

Foram encontrados altos coeficientes alfa de Cronbach para as duas formas. Também foram encontradas correlações entre as duas formas e os outros instrumentos, para os pacientes agrupados conforme tipo e gravidade da demência.

Conclusão:

A EQM é uma escala útil para identificar queixa de memória e pode ser útil para discriminar idosos demenciados de normais. Estudos subsequentes deverão ser realizados para verificar essas informações.
