Resumen

Antecedentes: El propósito de este estudio fue determinar la relevancia de la relación entre la red cerebral y el manejo de los lazos sociales. Método: los participantes son 52 adultos mayores coreanos de 65 años o más que viven en Ganghwa-gun, Incheon. Utilizamos un índice de tríada cerrada (CTI), que es la unidad de análisis más básica en el estudio de los fenómenos grupales. Este índice es una variable de red social que ha demostrado tener una implicación diferente dependiendo de la condición y el rol del sujeto. Después de realizar dos encuestas por cuestionario a intervalos de tres años, los participantes se clasificaron en un grupo aumentado y un grupo disminuido de acuerdo con el cambio de CTI. Se siguió el análisis de fMRI en estado de reposo para investigar la diferencia de las redes cerebrales entre los grupos.Resultados: Según el análisis del estudio, todos los participantes que habían aumentado en número de CTI tienen una mayor eficiencia local que el grupo de participantes que no tuvieron ningún efecto o disminuyeron en CTI. Conclusiones: Nuestro estudio sugiere que la relación social que está sustancialmente relacionada con la red cerebral es un factor importante en el envejecimiento exitoso. Por último, dado que existe una restricción de que el estudio no puede explicar el aspecto causal de la red cerebral y la relación tríada, existe la necesidad de una mayor investigación.
