Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this project, individuals with obesity and control individuals were recruited and followed up every year. Clinical neuropsychological scores, olfactory function tests, and functional magnetic resonance imaging (fmri) were performed to describe the brain function characteristics under different odor stimulation in fasting and after eating, and to explore the pathogenesis and clinical classification of obese patients. The correlation analysis between imaging analysis values and clinical laboratory data, neuropsychological scores and olfactory behavior scores was performed to explore indicators related to cognitive decline and provide new insights into the etiology and classification of obese patients. Combined with clinical evaluation and imaging examination, the changes of cognitive behavior and brain structure and function in obese patients were followed up.
