Abstract
We investigated the relationship between confabulations and the ability to process chronological characteristics of memories in Alzheimer's Disease (AD).We evaluated provoked confabulations, spontaneous confabulations, and time perception in 31 AD patients. We evaluated provoked confabulations with questions probing general and personal knowledge. We evaluated spontaneous confabulations with a scale rated by nursing and medical staff. Regarding time perception, we invited the participants to perform a simple ongoing activity (i.e., deciding whether words were abstract or concrete), in order to provide a verbal estimation of the elapsed time intervals.We observed significant positive correlations between provoked/spontaneous confabulations and deviations in time estimation on the time perception task.These findings demonstrate a relationship between confabulations in AD and difficulties in processing the chronological characteristics of elapsed events.
Investigamos la relación entre las confabulaciones y la capacidad para procesar las características cronológicas de los recuerdos en la enfermedad de Alzheimer (EA). Evaluamos las confabulaciones provocadas, las confabulaciones espontáneas y la percepción del tiempo en 31 pacientes con EA. Evaluamos las confabulaciones provocadas mediante preguntas que exploraban el conocimiento general y personal. Evaluamos las confabulaciones espontáneas mediante una escala puntuada por el personal médico y de enfermería. En cuanto a la percepción del tiempo, pedimos a los participantes que realizaran una actividad continua simple (es decir, decidir si las palabras eran abstractas o concretas) con el fin de proporcionar una estimación verbal de los intervalos de tiempo transcurridos. Observamos correlaciones positivas significativas entre las confabulaciones provocadas/espontáneas y las desviaciones en la estimación temporal en la tarea de percepción del tiempo. Estos hallazgos demuestran una relación entre las confabulaciones en la EA y las dificultades para procesar las características cronológicas de los acontecimientos transcurridos.
