Resumen
El objetivo de este trabajo es describir, desde la neuropsicología, el proceso de Toma de Decisiones (TD) en sujetos que padecen la Enfermedad de Alzheimer (EA). Para ello, se estableció una comparación del desempeño en TD de 40 sujetos con diagnóstico de enfermedad de Alzheimer con el desempeño de un grupo control de 40 sujetos sin diagnóstico de enfermedad neurológica y /o psiquiátrica, pareados por NSEC. El desempeño en la TD se evaluó con la tarea de Game Dice Task (GDT) ?Tarea del Juego de los Dados de Brand?. También se aplicaron otras pruebas y tareas de evaluación cognitiva para determinar la relación de la TD con otras Funciones Ejecutivas (FE). Los resultados permitieron establecer que el proceso de TD se deteriora desde los comienzos de la enfermedad, evidenciando que el desempeño de los sujetos con EA es significativamente inferior al de los sujetos sanos, con un porcentaje mayor de respuestas de riesgo y aumento significativo de los tiempos de respuesta. También se observó deterioro en todas las funciones ejecutivas evaluadas. El trabajo provee evidencia empírica que soporta la idea de que la TD se encuentra estrechamente relacionada a las demás FE.
The purpose of this study is to describe the impairment in the decision making (DM) process in subjects with diagnosis of Alzheimer’s disease (AD). The DM performance was assessed on 40 subjects diagnosed with AD and then compared against 40 control subjects with no neurological or psychiatric disease. The DM was evaluated using the Game Dice Task developed by Brand. Subjects were also administered other cognitive assessment tests in order to determine the relationship between the DM with other executive functions. The results show that the DM process seems to be impaired in patients with AD from the early stages of the disease. The results also show that the DM performance of the subjects with diagnosis of AD seems to be very inferior when compared to that of healthy subjects. DM assessment show that subjects with AD take more risky answers and have a longer reaction time to make the decision than those with no neurological disease. It was also observed that all executives functions seem to be deteriorated as well. This research shows empiric evidence about the relationship between DM and executive functions.
