[Evaluation of the diagnostic value of a Spanish adaptation of the Buschke Memory Impairment Screen in the detection of dementia and cognitive impairment]. / Evaluacion de la utilidad diagnostica de una adaptacion espanola del Memory Impairment Screen de Buschke para detectar demencia y deterioro cognitivo.

INTRODUCTION: Screening tests for dementia are a fundamental tool in specialist consultation and primary care. The instruments currently used are time-consuming and the diagnostic performance they offer is rather poor. The original version of the Buschke Memory Impairment Screen (MIS) is a quick simple test with high discriminatory power. AIMS: Our aim was to validate a Spanish version of the MIS in specialist consultation. PATIENTS AND METHODS: We conducted a prospective study in 91 subjects aged over 60 who visited the outpatient department for cognitive evaluation. All the patients received a similar diagnostic evaluation and the MIS was administered as a blind test. This Spanish version of the MIS was produced by means of a cross-cultural adaptation. RESULTS: The area below the ROC curve for dementia on the MIS was 0.92, with a similar result for cognitive deterioration (CD). A cut-off score of 4 or less offered a sensitivity rate of 91.9% (CI 95%: 83.4-96.4%) and a specificity level of 81.0% (CI 95%; 70.3-88.6%) for the detection of CD. Likewise, a cut-off score of 3 or below presented a sensitivity rate of 96.1% (CI 95%: 85.7-99.3%) and a degree of specificity of 72.6% (CI 95%: 63.2-80.3%) for the detection of dementia. Interobserver and test-retest reliability (0.85 and 0.81, respectively) were adequate. CONCLUSIONS: This version of the Buschke MIS offers a high level of discriminatory power both for dementia and for CD, as well as an adequate degree of inter and intraobserver reliability within the context of a specialist consultation. Because it is quick (less than 4 minutes) and simple to administer, MIS represents a reasonable alternative to other screening methods.

Evaluación de la utilidad diagnóstica de una adaptación española del Memory Impairment Screen de Buschke para detectar demencia y deterioro cognitivo / Evaluation of the diagnostic value of a spanish adaptation of the buschek memory impairment screen inthe detection of dementia and cognitive impairment

Introducción. Los tests de cribado para demencia son una herramienta fundamental en consulta especializada y atención primaria. Los instrumentos actuales son largos y ofrecen unas rentabilidades diagnósticas discretas. El Memory Impairment Screen (MIS) de Buschke es un test sencillo, rápido y con elevado poder discriminador en su versión original. Objetivo. Validar una versión española del MIS en consulta especializada. Pacientes y métodos. Estudio prospectivo en 91 sujetos mayores de 60 años que acudieron a consulta ambulatoria para valoración cognitiva. Todos los pacientes recibieron similar valoración diagnóstica y el MIS se aplicó de forma ciega. Esta versión española del MIS se realizó mediante una adaptación transcultural. Resultados. El área bajo la curva ROC para demencia del MIS fue 0,92, con similar resultado para deterioro cognitivo (DC). Un punto de corte de 4 o menos presentó una sensibilidad del 91,9% (IC 95%: 83,4-96,4%) y especificidad del 81,0% (IC 95%; 70,3-88,6%) para detectar DC; asimismo, un punto de corte de 3 o menos presentó una sensibilidad del 96,1% (IC 95%: 85,7-9,3%) y especificidad del 72,6% (IC 95%: 63,2-80,3%) para detectar demencia. Existió una adecuada fiabilidad interobservador (0,85) y test-retest (0,81). Conclusiones. Esta versión del MIS de Buschke ofrece un elevado poder discriminador tanto para demencia como DC, junto a una adecuada fiabilidad inter e intraobservador en el entorno de una consulta especializada. Su rapidez (menos de 4 minutos) y su sencillez hacen del MIS una alternativa razonable a otros tests de cribado (AU)
