The set-test evaluates the verbal fluency in 4 categories: colors, animals, fruits and cities. It has been proposed as a diagnostic aid in dementia in elderly patients. Therefore, we have evaluated its yield in a normative control reference group of 79 individuals and in 56 patients with possible dementia. It had a positive correlation of 73 with minimental test. The cut-off value was 29 in adults an 27 in elderly people. A lower score is indicative of dementia. Sensitivity was 79% and specificity 82%, with 20% of incorrectly classified patients. Considering the short duration of the test, we think that it is very useful for the evaluation of patients with dementia.
