          Abstract

          Abstract Objective: to describe the effects of neuromodulation on the performance of executive functions in overweight and/or individuals with obesity. Methods: articles published in PubMed, ScienceDirect, BIREME, and Web of Science databases were selected using the following combination of descriptors: (“problem solving” OR “executive function” OR memory) AND (tDCS OR TMS) AND obesity. After applying the selection criteria, 08 articles were included for analysis. Results: the articles included had an average of 30.1 participants per study, with a minimum of 12 and a maximum of 76. The overall nutritional status ranged from underweight to grade 3 obesity, and the general mean body mass index was 28,1 kg/m2. Regarding the instruments used to assess executive functions, the most frequent were: the flanker paradigm; binocular rivalry for Continuous Flash Suppression (bCFS/NoCFS); Stroop task; Go/No-Go task; and N-back task. The primary outcomes were dependent on the neuromodulation target site. Reduced food craving and improved performance in the active group were observed from decreased response time and increased precision in cognitive tasks. Conclusion: neuromodulation can generate changes in executive functions, reducing food cravings in overweight and individuals with obesity.

          Resumen Objetivo: describir los efectos de la neuromodulación en el desempeño de funciones ejecutivas en pacientes con sobrepeso y/o obesidad. Métodos: se seleccionaron artículos publicados en las bases de datos PubMed, ScienceDirect, BIREME y Web of Science utilizando la siguiente combinación de descriptores: (“resolución de problemas” O “función ejecutiva” O memoria) Y (tDCS O TMS) Y obesidad. Después de aplicar los criterios de selección, 08 artículos fueron incluidos para el análisis. Resultados: los artículos incluidos tuvieron un promedio de 30,1 participantes por estudio, con un mínimo de 12 y un máximo de 76. El estado nutricional general osciló entre bajo peso y obesidad grado 3, y el índice de masa corporal promedio general fue de 28,1 kg/m2. En cuanto a los instrumentos utilizados para evaluar las funciones ejecutivas, los más frecuentes fueron: paradigma del flanqueador; rivalidad binocular para la supresión continua de flash (bCFS/NoCFS); tarea de Stroop; Tarea Go/No-Go; y tarea N-back. Los resultados primarios dependieron del sitio objetivo de la neuromodulación. Se observó una reducción del antojo de alimentos y un mejor rendimiento en el grupo activo debido a la disminución del tiempo de respuesta y al aumento de la precisión en las tareas cognitivas. Conclusión: la neuromodulación puede generar cambios en las funciones ejecutivas, reduciendo el antojo de alimentos en personas con sobrepeso y obesidad.
