A comprehensive review examines neurocognition and hormones in obesity and eating disorders, revealing important links.

The research aims to explore the neurocognitive mechanisms and hormone associations in obesity with and without eating disorders.
Cross-sectional analysis of 171 women categorized into obesity with eating disorders, obesity without, and healthy controls.
Neurocognitive assessments included attention/inhibition and decision-making tasks.
Measured impulsivity and fasting levels of hormones like ghrelin, insulin, leptin, and LEAP2.
Applied structural equation modeling to analyze relationships between neurocognition and hormonal levels.
Obesity with eating disorders showed greater attentional lapses and higher impulsivity compared to healthy controls.
LEAP2 levels were higher, and ghrelin levels were lower in both obesity groups versus healthy controls.
Leptin was found to uniquely predict attentional lapses, slower reaction times, and impulsivity traits.

Camacho-Barcia et al. (2026) studied this question.
