Abstract Executive dysfunction is associated with the inability to control aberrant behaviors, such as chronic overeating (Moore, Sabino, Koob, & Cottone, 2017). Obese individuals often report great difficulties controlling eating behaviors, despite a desire to successfully lose weight (Dohle, Diel, & Hofmann, 2018). However, current literature lacks a systematic review about the relationship between executive dysfunction and Obesity. The aim of this study is to present the most important findings about this matter. First, a bibliometric analysis shows the evolution of the topic. Then, the Tree of Science tool is used to show a chronological review that provides a general description of the roots and current perspectives of the state of literature. Finally, clustering analysis of the co-citation network was employed to identify the different perspectives of the topic.
The main findings suggest four approaches:
(1) effects of body mass index on executive functioning, (2) executive functioning in children with overweight and obesity, (3) physical activity for adult obesity and (4) structural and functional brain changes in obesity. Preliminary data state that in obesity, poor food choices may be associated with frontal cognitive impairments that contribute to reduced orbitofrontal cortex volume.
Resumen Las alteraciones en el funcionamiento ejecutivo están relacionadas con la incapacidad de controlar conductas como comer en exceso. Pacientes con diagnóstico de obesidad reportan dificultades para controlar las conductas alimentarias, a pesar del deseo de perder peso. Sin embargo, la literatura actual carece de una revisión sistemática sobre la relación entre las alteraciones del funcionamiento ejecutivo y la obesidad. El objetivo de este estudio es presentar los hallazgos más importantes sobre este tema. Primero, un análisis bibliométrico muestra la evolución del tema. Luego, desde la herramienta Tree of Science se presenta una revisión cronológica que proporciona una descripción general de estudios seminales y perspectivas actuales del estado de la literatura. Finalmente, se empleó el análisis de agrupamiento de la red de co-citaciones para identificar las diferentes perspectivas del tema.
