Aspectos neurobiológicos en la toma de decisiones afectivas y sociales e influencia del estrés: posibles implicancias en la toma de decisiones clínicas.

Abstract

Decision-making is influenced by multiple unaware factors. We synthesize some neurobiological correlates of the affective and social components on decision-making, including the impact of acute and chronic stress. We also address the impact of heuristics and biases on clinical practice from the cognitive perspective. At an affective level, the hypothesis of the somatic marker has associated the peripheral body response with central nervous structures in the configuration of decisions; structures such as the orbitofrontal cortex and the hippocampus intervene. The reward and motivation dimensions are involved in social decision-making. In these types of decisions, the ability to mentally engage others and integrate their perspective into decision making is crucial. This function has been related to the posterior superior temporal sulcus, the temporoparietal junction, the anterior cingulate cortex, and the medial prefrontal cortex. However, compliance with socially established norms is also integrated into social decision-making. Acute or chronic stress may affect decision-making, positively or negatively. The hypothalamic-pituitary-adrenal axis has been involved in these processes together with corticostriatal, prefrontal, amygdala and hippocampal circuits. In clinical decision-making, "pre-reflective" emotional, social and cognitive factors are combined, influencing the decisions towards patients. We recommend emphasizing research in this field and strengthening education in this area to recognize these aspects adequately.

Neuro-psicopatología y procrastinación.

“…También hay que considerar que la toma de decisiones comprende un conjunto de procesos "prerreflexivos" asociados a los afectos y a la relación con los demás, junto con los propiamente cognitivos y racionales (15) . Los déficits cognitivos en múltiples trastornos neuropsicopatológicos se han asociado con alteraciones en el equilibrio de la excitación e inhibición sináptica en los circuitos de la corteza cerebral.…”
