Brief cognitive tests are widely used for dementia screening, but are usually influenced by education. The present work aimed to determine education-adjusted cut-off scores and correspondent sensitivity (S) and specificity (Sp) values of the category fluency (CF) test (animals/min) as a screening tool for Alzheimer disease (AD). Eighty-eight patients with mild AD and 117 normal matched controls were evaluated. Patients and controls were divided into 4 groups according to educational level (illiterates, 1 to 3, 4 to 7, and ≥8 y) and were administered the CF test. In each group, cut-off values were determined using Receiver Operator Characteristic analysis. The areas under Receiver Operator Characteristic curves were 0.922/0.914/0.963/0.954, for the identification of AD among the groups of illiterates, 1 to 3, 4 to 7, and ≥8 years of education, respectively. The cut-off points…
