Key result
Short Cognitive Performance Test adequately discriminates AD from non-demented subjects across all education levels.
Why the study?
The diagnostic accuracy of the Short Cognitive Performance Test (SKT) for mild cognitive impairment and dementia and its potential education bias were evaluated.
Does the Short Cognitive Performance Test accurately screen for mild cognitive impairment and dementia in older Brazilian adults?

Does the Short Cognitive Performance Test accurately screen for mild cognitive impairment and dementia in older Brazilian adults?
The SKT is a useful screening tool for cognitive impairment and dementia, but its accuracy for detecting MCI is limited in less-educated individuals.

May support SKT for AD screening across education levels in Brazilian elders; leaves open its utility for MCI in low-education groups.
The "Short Cognitive Performance Test" (Syndrom Kurztest, SKT) is a cognitive screening battery designed to detect memory and attention deficits. The aim of this study was to evaluate the diagnostic accuracy of the SKT as a screening tool for mild cognitive impairment (MCI) and dementia. A total of 46 patients with Alzheimer's disease (AD), 82 with MCI, and 56 healthy controls were included in the study. Patients and controls were allocated into two groups according to educational level (< or =8 years or >8 years). ROC analyses suggested that the SKT adequately discriminates AD from non-demented subjects (MCI and controls), irrespective of the education group. The test had good sensitivity to discriminate MCI from unimpaired controls in the sub-sample of individuals with more than 8 years of schooling. Our findings suggest that the SKT is a good screening test for cognitive impairment and dementia. However, test results must be interpreted with caution when administered to less-educated individuals.

Flaks et al. (2009) conducted a cross-sectional in Mild cognitive impairment and dementia (n=184). Short Cognitive Performance Test (SKT) vs. Clinical diagnosis (healthy controls and non-demented subjects) was evaluated on Diagnostic accuracy to discriminate AD from non-demented subjects and MCI from controls. The Short Cognitive Performance Test adequately discriminated Alzheimer's disease from non-demented subjects across education levels, and MCI from controls in those with >8 years of schooling.
