Abstract
Introducción: El concepto de Reserva Cognitiva, entendido de forma general, como el efecto protector adquirido, está
considerado por muchos autores como un mecanismo activo que se basa en la aplicación de los recursos aprendidos, debido
a una buena educación, profesión y/o inteligencia prémorbida. El Test de Stroop, se ha utilizado en la evaluación neuropsicológica
de las funciones ejecutivas, en enfermedades relacionadas con el envejecimiento, como es el caso de la Enfermedad de
Alzheimer. Objetivos: Pretendemos estudiar la influencia de la Reserva Cognitiva en las funciones ejecutivas, en sujetos con
Enfermedad tipo Alzheimer de Inicio Tardío y en sujetos sanos en una muestra portuguesa. Método: Se han utilizado dos muestras,
una constituida por 91 sujetos sanos y una segunda muestra formada por 32 sujetos diagnosticados de Demencia senil tipo
Alzheimer. Resultados: El grupo de sujetos sanos mostró un mejor rendimiento en el test, que el grupo con neuropatología. Se
encontraron diferencias significativas en el grupo de sujetos sanos entre alta y baja Reserva Cognitiva. Conclusiones: El Test
Stroop, muestra una alta sensibilidad en la determinación de alteraciones en las funciones ejecutivas así como la influencia de
la reserva cognitiva en la ejecución del mismo.
Palabras Clave: Enfermedad de Alzheimer.
The Cognitive Reserve concept, generally understood as the acquired protective effect, is considered by many authors as an active mechanism that is based on the application of previously learned resources, due to a good education, profession and/or premorbid intelligence. The Stroop Test has been used in the neuropsychological assessment of executive functions in aging-related disease, such as Alzheimer’s Disease. Objectives: We intend to study the influence of cognitive reserve in executive functions in subjects with late onset Alzheimer´s disease, and in healthy subjects in a Portuguese sample. Method: We used two samples, one consisting of 91 healthy subjects and a second sample of 32 subjects diagnosed with senile dementia of the Alzheimer type. Results: The group of healthy subjects showed better performance on the test, than the pathologic group. Significative differences were found in the healthy group between high and low cognitive reserve subgroups. Conclusions: The Stroop Test, shows a high sensitivity in determining alterations in executive functions and the influence of cognitive reserve in that function.
