Memoria de trabajo, control inhibitorio y flexibilidad cognitiva en pacientes con diferentes grados de severidad en la Enfermedad de Alzheimer
Contenido principal del artículo
Resumen
El objetivo del estudio consistió en investigar las Funciones Ejecutivas (FE) en pacientes con Enfermedad de Alzheimer (EA) en función del grado de severidad. Se estudiaron 50 pacientes con EA y 60 Sujetos sin deterioro cognitivo (SSDC) en un estudio no experimental- transversal con un muestreo no probabilístico. Los resultados demostraron que: la ejecución del test de dígitos que valora memoria de trabajo, no diferencia entre los pacientes con EA leve y los SSDC; el control inhibitorio, evaluado mediante el test de Stroop, permite diferenciar a los pacientes con EA en fase moderada y grave; y en la flexibilidad cognitiva, medida a través de diferentes variables, existen diferencias inconsistentes. Los pacientes con EA tienen mayor afectación en tareas que evalúan memoria de trabajo, control inhibitorio y la flexibilidad cognitiva, con independencia del grado de severidad y de la edad, en comparación con SSDC.
