Abstract

OBJECTIVES: To investigate the applicability of the Bayer - Activities of Daily Living scale and its efficiency in differentiating individuals with mild to moderate dementia from normal elderly controls. METHOD: We selected 33 patients with diagnosis of mild to severe dementia, according to ICD-10 criteria, and 59 controls. All the subjects were evaluated with the Mini-Mental State Examination 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-Mental State 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 Clinical Dementia Rating Scale 0 (controls; n = 59) versus Clinical Dementia Rating Scale 1 (mild dementia; n = 15), Clinical Dementia Rating Scale 0 versus Clinical Dementia Rating Scale 2 (moderate dementia; n = 13), and for Clinical Dementia Rating Scale 1 versus Clinical Dementia Rating Scale 2 (p < 0.003). DISCUSSION: The Bayer - Activities of Daily Living scale and Mini-Mental State Examination differentiated elderly controls from patients with mild or moderate dementia, and patients with mild dementia from those with moderate dementia. CONCLUSIONS: The results suggest that the Bayer - Activities of Daily Living scale applied to an informant can help in the diagnosis and follow-up of Brazilian patients with mild to moderate dementia.
