Objective:
Evaluate the performance on verbal fluency (VF) in our population in a Brazilian sample checking the influence of age and literacy.
Methods:
336 people without neurological or psychiatric complaints evaluated through Mini-Mental State Examination and VF (animals). For comparison, and to determine cut-off points, 65 people with cognitive loss followed at our clinic were also evaluated.
Results:
We found a mean of 13.8 animals in 1 minute, with the following distribution: illiterates, 11.9; up 4 years of education, 12.8; 4 to 7 years, 13.4; 8 years or more, 15.8 (p = 0.0001). In relation to age the means were: up to 64 years, 13.7; 65 years or more, 13.9. There was no difference between the two groups. The cut-off points were 9 for people under 8 years of education with a sensitivity of 75% for illiterates, 100% for low educational level (up 4 years), and 87% for middle level (4 to 7 years). The specificity was respectively 79%, 84%, and 88%. For the high educational level the mean was 13 with a sensitivity of 86% and specificity of 67%.
Conclusions:
In the VF (animals) there is a significant influence of schooling and different cut-off points should be used.
