Resumen

Los pacientes con enfermedad de Alzheimer leve muestran dificultades para realizar actividades cotidianas debidas a la afectación del control atencional, las cuales describen diferencias cualitativas significativas entre el envejecimiento normal y el patológico. Las tareas de generación aleatoria permiten valorar esta capacidad; sin embargo, su utilización en personas mayores y con EA puede estar sesgada por las demandas de memoria que imponen. Interesados en evaluar específicamente el control atencional en estos sujetos, diseñamos una tarea de generación aleatoria manual con mínimas exigencias de memoria. Se aplicó a un grupo de personas mayores sanas y a un grupo de pacientes con EA inicial. Los resultados revelaron diferencias significativas entre ambos grupos en distintos índices de aleatorización, mostrando los pacientes más dificultades para evitar secuencias estereotipadas y cambiar de estrategias. Estos resultados confirman que esta tarea permite valorar de modo delimitado el control atencional en individuos mayores, y discriminar entre el envejecimiento normal y el inicio de la EA. Por tanto, la tarea de generación aleatoria manual podría considerarse en la detección temprana de la EA.
