Abstract

Objective: Evaluate the accuracy of two semantic categories of the verbal fluency test (supermarket and animal categories) to separate healthy elderly individuals and lower educated Alzheimer’s disease patients. Methods: We evaluated 69 older adults with less than 5 years of schooling, consisting of 31 healthy elderly, and 38 patients diagnosed with Alzheimer’s disease. Semantic verbal fluency was evaluated using the animal and supermarket categories. Mann-Whitney U and Independent t Tests were used to compare the two groups, and the diagnostic accuracy of the tests was analyzed by sensitivity, specificity, likelihood ratio’s, and the Area Under the Curve (AUC). Results: We found a significant difference between the healthy older and Alzheimer’s disease groups, in both, animal (p = 0.014) and supermarket verbal fluency (p < 0.001). The supermarket category showed better overall diagnostic accuracy (AUC = 0.840, 95% CI = 0.746-0.933; p < 0.001) compared to the animal category (AUC = 0.671, 95% CI = 0.543-0.800; p = 0.014). Conclusion: The supermarket category of semantic verbal fluency provides better accuracy than the animal category for the identification of dementia in a Brazilian elderly population with low educational level.
