Diagnosis of dementia is a challenge in populations with heterogeneous educational background.
Objective:
To compare the accuracies of two delayed recall tests for the diagnosis of dementia in a community with high proportion of illiterates.
Method:
The delayed recall of a word list from the CERAD battery (DR-CERAD) was compared with the delayed recall of objects presented as line drawings from the Brief Cognitive Screening Battery (DR-BCSB) using ROC curves. Illiterate (23 controls and 17 patients with dementia) and literate individuals (28 controls and 17 patients with dementia) were evaluated in a community-dwelling Brazilian population.
Results:
The DR-BCSB showed higher accuracy than the DR-CERAD in the illiterate (p=0.029), similar accuracy in the literate individuals (p=0.527), and a trend for higher accuracy in the entire population (p=0.084).
Conclusion:
the DR-BCSB could be an alternative for the diagnosis of dementia in populations with high proportion of illiterates.
