Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Bariatric surgery is the most effective, long-term treatment for morbid obesity, and consistent with previous findings, individuals who lose significant weight after surgery also have improved cognition or "brain function". The mechanisms behind these cognitive improvements are currently unknown, but are the focus of much research effort. The goal of this pilot study is to thoroughly describe these changes in surgical versus medical weight loss patients over time in a repeated measures fashion.
