Resumen
El objetivo de esta investigación es describir el proceso de toma de decisiones en 60
adolescentes policonsumidores y no consumidores en edades entre los 13 y 17 años, en dos
clínicas psiquiátricas y una institución educativa, en Cartagena de Indias. Para ello, se ha
establecido una investigación con enfoque cuantitativo de nivel descriptivo y comparativo,
que pretende la evaluación del funcionamiento ejecutivo (Batería de funciones ejecutivas y
Lóbulos Frontales-BANFE) y del patrón de rendimiento de toma de decisiones (Iowa
Gambling Task) en esta muestra seleccionada. Los resultados permitieron concluir que los
policonsumidores exhiben alteraciones funcionales leves y severas en las áreas pre frontales
evaluadas, en comparación con los no consumidores quienes exhiben perfiles de
desempeño ejecutivo normal y normal alto. Se observa, en especial, un déficit significativo
en la corteza orbito-fronto-medial (54% de policonsumidores con alteración severa y leve)
que indica déficits en el procesamiento, integración, regulación e inhibición de estados
emocionales implicados en la toma de decisiones, y una desregulación en la jerarquización
de los estímulos reforzantes asociada a dificultades en la evaluación de la recompensa, en la
motivación, y en el aprendizaje asociativo y emocional. Lo anterior se traduce en la
existencia de una tendencia negativa encontrada tras cada grupo de elecciones de cartas
ventajosas en los policonsumidores, con un decremento a partir del segundo grupo de
cartas; y que explica la dificultad para abandonar el consumo a pesar de la pérdida
progresiva del poder reforzador de las drogas y del incremento de sus consecuencias
negativas.
The objective of this research is to describe the decision-making process in 60 polyconsumer adolescents and non-consumers between the ages of 13 and 17, in two psychiatric clinics and an educational institution, in Cartagena de Indias. To this end, an investigation has been established with a quantitative approach of a descriptive and comparative level, which aims to evaluate the executive functioning (Battery of executive functions and Frontal Lobes-BANFE) and the decision making performance pattern (Iowa Gambling Task) in This sample selected. The results allowed us to conclude that polyconsumers exhibit mild and severe functional alterations in the pre-frontal areas evaluated, compared to non-consumers who exhibit high normal and normal executive performance profiles. In particular, there is a significant deficit in the orbito-fronto-medial cortex (54% of polyconsumers with severe and mild alteration) that indicates deficits in the processing, integration, regulation and inhibition of emotional states involved in decision making, and a deregulation in the hierarchy of reinforcing stimuli associated with difficulties in the evaluation of the reward, in motivation, and in associative and emotional learning. This translates into the existence of a negative trend found after each group of advantageous card elections in polyconsumers, with a decrease from the second group of letters; and that explains the difficulty of abandoning consumption despite the progressive loss of the reinforcing power of drugs and the increase in their negative consequences.
