NCT ID NCT07704229
First seen Jul 15, 2026 · Last updated Jul 17, 2026 · Updated 2 times
Summary
This study investigates how sleeve gastrectomy, a common weight-loss surgery, impacts brain health and cognitive function in adults with severe obesity. Researchers will use brain scans and thinking tests to measure changes in brain age and mental performance over time. The goal is to understand why some patients see cognitive improvements after surgery while others do not, and to identify factors that predict better brain outcomes.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- sleeve gastrectomy (a surgical procedure that removes part of the stomach to promote weight loss)
- What this could lead to
- If successful, this research could reveal why some people experience brain health improvements after weight-loss surgery and help develop personalized strategies to protect cognitive function.
- What could go wrong
- This is an observational study, not a controlled trial, so it cannot prove cause and effect. Results may not apply to all people with obesity, and long-term cognitive benefits remain uncertain.
