Validación de la versión española de la Escala Cognitiva de Montreal (MoCA) como herramienta de cribado de deterioro cognitivo asociado a la esclerosis múltiple / Validation of the Spanish-language version of the Montreal Cognitive Assessment as a screening test for cognitive impairment in multiple sclerosis

Introducción: Las baterías neuropsicológicas empleadas tradicionalmente para el diagnóstico del deterioro cognitivo (DC) en la esclerosis múltiple son pruebas complejas que conllevan mucho tiempo. Se necesitan test más simples para detectar el DC en la práctica clínica diaria.ObjetivoEvaluar la validez diagnóstica y la fiabilidad de la escala Montreal Cognitive Assessment (MoCA) como herramienta de cribado de DC en la esclerosis múltiple frente a la Batería Neuropsicológica Breve.Material y métodosSe seleccionaron 52 pacientes (61,5% mujeres, edad media [desviación estándar] 41,7 [11,5] años). Se analizaron la fiabilidad (consistencia interna, interobservador y test-retest) y la validez de constructo (análisis factorial, coeficiente de correlación de Pearson y coeficiente de determinación) y de criterio (curva ROC, sensibilidad, especificidad, acuerdo global, valores predictivos positivo y negativo, cocientes de probabilidad positivo y negativo y nomograma de Fagan).ResultadosLa prevalencia de DC fue del 21,2% según la Batería Neuropsicológica Breve y del 25% según el MoCA. El MoCA mostró buena consistencia interna (alfa de Cronbach 0,822) y buena fiabilidad interobservador y test-retest (coeficiente de correlación intraclase de 0,80 y 0,96, respectivamente). El coeficiente de correlación entre la puntuación total de la Batería Neuropsicológica Breve y el MoCA fue de 0,82. El punto óptimo de corte en la curva ROC fue 25-26, con una sensibilidad del 91% y una especificidad del 93%.ConclusiónEl MoCA es una herramienta de cribado válida y fiable para la detección de DC en pacientes con esclerosis múltiple.

Introduction: The neuropsychological batteries traditionally used for the assessment of cognitive impairment (CI) in patients with multiple sclerosis are complex tests requiring a long time to administer. Simpler tests are needed to detect cognitive impairment in daily clinical practice.ObjectiveWe aimed to evaluate the diagnostic validity and reliability of the Montreal Cognitive Assessment (MoCA) test as a screening tool for CI in patients with multiple sclerosis, as compared against the Brief Neuropsychological Battery.Material and methodsWe recruited 52 patients with multiple sclerosis (61.5% women; mean age [standard deviation]: 41.7 [11.5] years). We analysed the reliability (internal consistency, interobserver reliability, and test-retest reliability), construct validity (factor analysis, Pearson correlation coefficient, and coefficient of determination), and criterion validity (ROC curve, sensitivity, specificity, total agreement, positive and negative predictive values, positive and negative likelihood ratios, and Fagan nomogram) of the MoCA test in this population.ResultsThe prevalence of CI was 21.2% according to findings from the Brief Neuropsychological Battery, and 25% according to the MoCA test. The MoCA test showed good internal consistency (Cronbach alpha, 0.822) and interobserver and test-retest reliability (intraclass correlation coefficient 0.80 and 0.96, respectively). The correlation coefficient between total Brief Neuropsychological Battery and MoCA test scores was 0.82. The optimal cut-off point on the ROC curve was 25-26, yielding 91% sensitivity and 93% specificity.ConclusionThe MoCA test is a valid and reliable tool for screening for CI in patients with multiple sclerosis.

[Donepezil therapy in patients with vascular and post-traumatic cognitive impairment: some clinical observations]. / Tratamiento con donepecilo en pacientes con deterioro cognitivo vascular y postraumático: observaciones clínicas.

INTRODUCTION: Donepezil is a procholinergic drug that slows down cognitive and functional impairment in patients with Alzheimer's disease. Little research has been carried out to study its effect in other types of neurobehavioural disorders. AIMS: The purpose of this study was to describe the response to donepezil therapy in patients with neurobehavioural disorders due to vascular and post-traumatic causes. CASE REPORTS: Donepezil was administered to four patients with mild cognitive impairment due to vascular causes, to two patients with vascular dementia and to two patients with post-traumatic dementia. Following an average time of four months, the effects exerted on the cognitive, functional and behavioural areas were evaluated. One patient did not tolerate the drug and another suffered an episode of congestive heart failure that gave rise to a moderate neurobehavioural exacerbation. Two patients underwent a moderate improvement, three patients showed a slight improvement and no changes were observed in one patient. In general, memory, attention, depression, apathy and psychotic traits tended to improve. Aggressiveness/irritability tended to get worse. The functional repercussions of these changes were negligible or inexistent. CONCLUSIONS: Treatment with donepezil improved cognition and conduct in patients with neurobehavioural disorders due to vascular or post-traumatic causes. These results will have to be confirmed and expanded by means of controlled studies, and research must continue into the characteristics of responding patients and the relevance of their responses.

Tratamiento con donepecilo en pacientes con deterioro cognitivo vascular y postraumático: observaciones clínicas / Donepezil therapy in patients with vascular and post-traumatic cognitive impairment: some clinical observations

Introducción. El donepecilo es un fármaco procolinérgico que atenúa el deterioro cognitivo y funcional en los pacientes con enfermedad de Alzheimer. Su efecto en otro tipo de trastornos neuroconductuales no se ha estudiado lo suficiente. Objetivo. Describir la respuesta al tratamiento con donepecilo en pacientes con alteraciones neuroconductuales de causa vascular y postraumática. Casos clínicos. Se pautó el donepecilo a cuatro pacientes con deterioro cognitivo ligero de causa vascular, a dos pacientes con demencia vascular y a dos pacientes con demencia postraumática. Tras un tiempo medio de cuatro meses, se evaluaron los efectos en las áreas cognitiva, funcional y conductual. Un paciente no toleró el fármaco y otro paciente desarrolló un episodio de insuficiencia cardíaca congestiva que provocó un empeoramiento neuroconductual moderado. Dos pacientes experimentaron una mejoría moderada, tres pacientes tuvieron una mejoría ligera y en un paciente no se observaron cambios. En general, se apreció una tendencia a la mejoría en la memoria, la atención, la depresión, la apatía y los rasgos psicóticos. La agresividad / irritabilidad tendió a empeorar. La repercusión funcional de estos cambios fue mínima o nula. Conclusiones. El tratamiento con donepecilo mejora la cognición y la conducta en pacientes con alteraciones neuroconductuales de causa vascular o postraumática. Se precisa confirmar y ampliar estos resultados mediante estudios controlados, así como seguir investigando en torno a las características de los pacientes respondedores, y a la relevancia de la respuesta (AU)
