The Bayer - Activities of Daily Living Scale (B-ADL) in the differentiation between mild to moderate dementia and normal aging

AbstractObjectives: To investigate the applicability of the Bayer - Activities of Daily Living scale and its efficiency in differentiatingindividuals with mild to moderate dementia from normal elderly controls. Method: We selected 33 patients with diagnosis ofmild to severe dementia, according to ICD-10 criteria, and 59 controls. All the subjects were evaluated with the Mini-Mental StateExamination and the Clinical Dementia Rating Scale and the Bayer - Activities of Daily Living scale was applied to informants.Results: The internal consistency of the Bayer - Activities of Daily Living was high (Cronbach’s alpha = 0.981). Mean Mini-MentalState Examination and Bayer - Activities of Daily Living scores of demented patients and controls were significantly different (p < 0.001).Mean Mini-Mental State Examination and Bayer - Activities of Daily Living scores were significantly different between ClinicalDementia Rating Scale 0 (controls; n = 59) versus Clinical Dementia Rating Scale 1 (mild dementia; n = 15), Clinical DementiaRating Scale 0 versus Clinical Dementia Rating Scale 2 (moderate dementia; n = 13), and for Clinical Dementia Rating Scale 1versus Clinical Dementia Rating Scale 2 (p < 0.003). Discussion: The Bayer - Activities of Daily Living scale and Mini-Mental StateExamination differentiated elderly controls from patients with mild or moderate dementia, and patients with mild dementia fromthose with moderate dementia. Conclusions: The results suggest that the Bayer - Activities of Daily Living scale applied to aninformant can help in the diagnosis and follow-up of Brazilian patients with mild to moderate dementia.Descriptors: Dementia; Diagnosis; Activities of daily living; MMSE; AgeingResumoObjetivos: Investigar a aplicabilidade da escala Bayer - Atividades de Vida Diaria e sua eficiencia em diferenciar individuos comdemencia leve a moderada de individuos normais. Metodo: Foram selecionados 33 pacientes com diagnostico de demencia levea grave, de acordo com os criterios da CID-10, e 59 controles. Todos os individuos foram avaliados pelo Mini-Exame do EstadoMental e pela Escala de Avaliacao Clinica de Demencia e os informantes responderam a Bayer - Atividades de Vida Diaria.Resultados: A consistencia interna da Bayer - Atividades de Vida Diaria foi alta (Cronbach Alpha = 0,981). A pontuacao mediado Mini-Exame do Estado Mental e da Bayer - Atividades de Vida Diaria foi significativamente diferente entre os pacientes comdemencia e o grupo controle (p < 0,001). Os valores do Mini-Exame do Estado Mental e da Bayer - Atividades de Vida Diariaforam significativamente diferentes entre a Escala de Avaliacao Clinica de Demencia 0 (controles; n = 59) e a Escala de AvaliacaoClinica de Demencia 1 (demencia leve; n = 15), a Escala de Avaliacao Clinica de Demencia 0 e a Escala de Avaliacao Clinica deDemencia 2 (demencia moderada; n = 13) e entre a Escala de Avaliacao Clinica de Demencia 1 e a Escala de Avaliacao Clinicade Demencia 2 (p < 0,003). Discussao: A Bayer - Atividades de Vida Diaria e o Mini-Exame do Estado Mental diferenciaramcontroles idosos de pacientes com demencia leve ou moderada, e pacientes com demencia leve daqueles com demencia mode-rada. Conclusoes: Os resultados sugerem que a Bayer - Atividades de Vida Diaria, aplicada aos cuidadores, e um instrumentoque pode ajudar no diagnostico e seguimento de pacientes brasileiros com demencia leve a moderada.Descritores: Demencia; Diagnostico; Atividades cotidianas; MMSE; Envelhecimento
