Utilidad diagnóstica de test cognitivos breves en el cribado de deterioro cognitivo / Diagnostic performance of brief cognitive tests in cognitive impairment screening

Introducción y objetivos: Evaluar y comparar la utilidad diagnóstica (UD) para el cribado de deterioro cognitivo (DC) de los test cognitivos breves (TCB) recomendados por la Guía de práctica clínica sobre la atención integral a las personas con enfermedad de Alzheimer y otras demencias. Material y métodos: Estudio de fase iii de evaluación de pruebas diagnósticas en el que se ha incluido en Atención Primaria a sujetos con sospecha de DC. A todos se les ha aplicado Mini-Mental State Examination (Mini-Mental), Mini Examen Cognoscitivo (MEC), Short Portable Mental Status Questionnaire (SPMSQ), Memory Impairment Screen (MIS), test del reloj (TdR), Eurotest, Fototest y test de alteración de memoria (T@M). El diagnóstico de DC se ha realizado de forma independiente y cegada con respecto a los resultados de los TCB. La UD se ha evaluado mediante el área bajo la curva ROC (aROC). Resultados: Se ha incluido a 141 sujetos (86 con DC). El Eurotest y el T@M (0,91 ± 0,02 [aROC ± EE] y 0,90 ± 0,02, respectivamente), los instrumentos que requieren más tiempo (7,1 ± 1,8 [media ± DE] y 6,8 ± 2,2 min, respectivamente) tienen una UD significativamente superior a la del Mini-Mental, MEC, SPMSQ y TdR, pero no a la del MIS y Fototest (0,87 ± 0,03 ambas), requiriendo este último menos de la mitad del tiempo (2,8 ± 0,8 min). T@M y MIS solo evalúan memoria y el último no es aplicable a analfabetos. Conclusiones: Los instrumentos más recomendables para el cribado de DC en Atención Primaria son Eurotest, T@M y Fototest, siendo el último más eficiente por requerir la mitad de tiempo. (AU)

Introduction and objectives: This study aims to assess and compare the diagnostic performance of brief cognitive tests for cognitive impairment (CI) screening recommended by the Spanish guidelines for the integral care of people with Alzheimer's disease and other dementias. Material and methods: We performed a phase iii study into the accuracy of diagnostic tests, including patients with suspected CI in a primary care setting. All patients completed the Mini–Mental State Examination (MMSE), the Mini Examen Cognoscitivo (MEC), the Short Portable Mental Status Questionnaire (SPMSQ), the Memory Impairment Screen (MIS), the Clock Drawing Test (CDT), the Eurotest, the Fototest, and the Memory Alteration Test (M@T). CI was diagnosed independently by researchers blinded to scores on these tests. Diagnostic performance was evaluated by calculating the area under the receiver operating characteristic curve (AUC). Results: The study included 141 individuals (86 with CI). The Eurotest and M@T (AUC ± SE: 0.91 ± 0.02 and 0.90 ± 0.02, respectively) took longer to administer (mean [SD]: 7.1 [1.8] and 6.8 [2.2] min, respectively) and have significantly better diagnostic performance compared to the MMSE, MEC, SPMSQ, and CDT, but not compared to MIS or Fototest (both with an AUC of 0.87 ± 0.03), with the latter taking less than half as long to administer (2.8 [0.8] min). The M@T and MIS only evaluate memory, and the latter cannot be administered to illiterate people. Conclusion: The most advisable tests for CI screening in primary care are the Eurotest, M@T, and Fototest, with the latter being the most efficient as it takes half as long to administer. (AU)
