Subjective Memory Complaints (SMC) are frequent among adults and elderly and are associated with poor qualityof life. The etiology and clinical significance of SMCs are unclear, but these complaints are associated with objective cognitivedecline or with depression, anxiety and psychosocial stressors. Biological and physiological brain alterations resembling thosein Alzheimer?s Disease have been found in SMC. SMC can evolve with different outcomes and represent the initial symptomor a risk factor of dementia. Active systematic search can be useful for early screening of candidates for preventive ortherapeutic interventions.
Objective:
To propose a Memory Complaints Scale (MCS) as an instrument for actively searchingfor memory complaints and to investigate its utility for discriminating demented from cognitively normal elderly.Methods:
Atotal of 161 patients from a teaching behavioral neurology outpatient unit of a tertiary hospital were studied. The MCS wasused in two ways, by direct application to the patient and by application to the patient?s companion. Cognitive tests assessingdepression and daily living activities were also applied.Results:
High Cronbach?s alpha coefficients were found for the twoapplication methods. Correlations between the two versions and the other instruments administered for patients grouped bytype and severity of dementia were also found.Conclusion:
The MCS is a useful scale for identifying memory complaintsand discriminating demented from cognitively normal elderly. Further studies confirming these findings are warranted.
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 eestressores psicossociais. Foram demonstradas alterações biológicas e fisiológicas encefálicas semelhantes às da doençade Alzheimer. Pode ter diferentes desfechos e representar sintoma inicial ou fator de risco para demência. A busca ativae sistematizada pode ser útil na identificação precoce de pessoas que poderão receber intervenções preventivas outerapêuticas.
