Neurophysiological markers of subjective memory complaints in healthy people
2022
Con el envejecimiento de la población es importante comprender los cambios neurofisiológicos que se producen. En este contexto, las quejas subjetivas de la memoria (QSM) se están convirtiendo en un tema de interés ya que se han considerado un factor de riesgo para desarrollar trastornos relacionados con demencias como el deterioro cognitivo leve y enfermedad de Alzheimer. Por lo tanto, es importante investigar los biomarcadores tempranos para la detección y la planificación de los tratamientos. En este sentido, el procesamiento de emociones faciales es una importante función cognitiva comúnmente afectada en personas con trastornos relacionados con demencias que podría ayudar a analizar camb…
Subjective Memory Complaints and Decision Making in Young and Older Adults: An Event-Related Potential Study
2021
Subjective memory complaints (SMCs) may affect decision-making processes. This study aimed to investigate the neuronal correlates of feedback processing during a decision-making task in young and older adults with and without SMCs. Event-related potentials and behavioral performance during the Iowa gambling task were recorded in a total of 136 participants (65 young adults, 71 older adults). The participants were divided into two groups according to their SMCs (with SMCs: n = 60, without SMCs: n = 76). Feedback-related negativity (FRN) and P3 were analyzed in the feedback stage of the decision-making process. Older adults with SMCs scored worse in the ambiguity phase than older adults witho…
