title: The Bayer: Activities of Daily Living Scale (B-ADL) in the differentiation between mild to moderate dementia and normal aging.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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).
  
  
  CONCLUSIONS
  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.
