To date, the cut\u2010off scores for mild cognitive impairment (MCI) have not been determined. Given the need for an earlier diagnosis of mild dementia, new cut\u2010off values are also necessary, taking into account cultural and educational effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>One hundred and fifty\u2010seven older adults (mean age: 69.6\u2009\u00b1\u20097.4 years) with 8 or more years of formal education (mean years of schooling 14.2\u2009\u00b1\u20093.8) attending a memory clinic at the Institute of Psychiatry University of Sao Paulo were included. Subjects were divided into three groups according to their cognitive status, established through clinical and neuropsychological assessment: normal controls, <jats:italic>n<\/jats:italic>\u2009=\u200962; MCI, <jats:italic>n<\/jats:italic>\u2009=\u200965; and mild or moderate dementia, <jats:italic>n<\/jats:italic>\u2009=\u200930. ROC curve analyses were performed for dementia <jats:italic>vs<\/jats:italic> controls, MCI <jats:italic>vs<\/jats:italic> controls and MCI <jats:italic>vs<\/jats:italic> dementia.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The cut\u2010off values were: 92\/93 for dementia <jats:italic>vs<\/jats:italic> controls (AUC\u2009=\u20090.99: sensitivity: 100%, specificity: 95%); 95\/96 for MCI <jats:italic>vs<\/jats:italic> controls (AUC\u2009=\u20090.83, sensitivity: 64%, specificity: 88%), and 85\/86 for MCI <jats:italic>vs<\/jats:italic> dementia (AUC\u2009=\u20090.91, sensitivity: 81%, specificity: 88%). The total CAMCOG score was more accurate than its subtests Mini\u2010mental State Examination, Verbal Fluency Test and Clock Drawing Test when used separately.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The CAMCOG discriminated controls and MCI from demented patients, but was less accurate to discriminate MCI from controls. The best cut\u2010off value to differentiate controls and demented was higher than suggested in the original publication, probably because only cases of mild to moderate dementia were included. This is important given the need for a diagnostic at earlier stages of Alzheimer's disease.
