Validation of the Brazilian version of mini-test CASI-S

Abstract

-O b j e c t i v e:To determine CASI-S accuracy in the diagnosis of dementia. M e t h o d: The Cognitive Abilities Screening Instrument -Short Form (CASI-S) was applied in 43 Alzheimer's disease (AD) patients and 74 normal controls. AD diagnosis was based on DSM-IV, NINCDS-ADRDA, and CAMDEX. CASI-S includes: registration, temporal orientation, verbal fluency (4-legged animals in 30s), and recall (3 words). Its maximum score is 33 points. A copy of 2 pentagons was added. Results: ROC curve showed an accuracy of 0.87, with standard error of 0.032, and 95% confidence intervall between 0.795 and 0.925. The cut-off score for cognitive deficit was 23, with sensitivity of 76.7%, specificity 86.5%, positive likelihood ratio (LR) 5.68, and negative LR 0.27. The cut-off score for subjects 70 years or older was 20, with sensitivity of 71.4% and specificity 97.1%. C o n c l u s i o n: CASI-S is a practical test, with high specificity, particularly in individuals above 70 years of age. The adding of the drawing test did not improve its accuracy.

Prospective and retrospective memory in mild Alzheimer's disease

“…Besides this age difference being small, the effect of age on cognitive performance is usually secondary to the effect of educational level [24][25][26] , which was similar in our groups of patients and controls. Dementia patients failure on ProM tasks can neither be explained by deficit of attention, visual perception or executive function as there was no correlation between ProM and the control tests for these cognitive functions.…”

Translation, cultural adaptation and psychometric evaluation of the Leganés cognitive test in a low educated elderly Brazilian population

“…In order to minimize such problems, several studies have been conducted to adjust cut-off values of existing instruments according to education levels, or to design new tools with a lower education impact in their total scores [6][7][8][9] . Cut-offs have been proposed in Brazil for some of the main cognitive screening instruments used in elderly [10][11][12][13] .…”

Rastreio cognitivo para idosos em atenção primára

“…No Brasil, há quatro estudos realizados com o CASI-S (Damasceno et al, 2005;de Oliveira et al, 2015;Martinelli et al, 2013;Rezende et al, 2013 (Damasceno et al, 2005).…”

“…As notas de corte encontradas no presente estudo serão comparadas com as encontradas na literatura brasileira, de ≥20 para sujeitos com mais de 70 anos (Damasceno et al, 2005).…”

“…O estudo brasileiro com o CASI-S (versão reduzida) encontrou correlação positiva com os anos de escolaridade e negativa com a idade (Damasceno et al, 2005).…”
