Investigating brain function differences in obesity subtypes

Research on Brain Function of Metabolism-based Artificial Intelligence Assisted Clinical Classification of Obesity

Shanghai 10th People's Hospital · NCT05892224

This study looks at how brain function differs among people with different types of obesity to see how it affects their health after weight loss surgery.

What this trial studies

This observational study aims to explore the brain function characteristics of patients with four different subtypes of obesity and how these relate to metabolic changes following laparoscopic sleeve gastrectomy (LSG). A total of 120 patients with obesity and 30 healthy individuals will undergo functional magnetic resonance imaging (fMRI) assessments at baseline and at multiple time points post-surgery. The study will evaluate various metabolic indicators and complications associated with weight loss to better understand the relationship between brain function and obesity-related health outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 16-65 with a BMI over 37.5 kg/m² or over 32.5 kg/m² with diabetes.

Not a fit: Patients with secondary causes of obesity, severe organ dysfunction, or contraindications for laparoscopic surgery may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding of obesity subtypes and tailored interventions for better metabolic health outcomes.

How similar studies have performed: While there have been studies on obesity and brain function, this specific approach focusing on subtypes and their metabolic implications is relatively novel.
