Summary

This study will test if weight-loss surgery can improve thinking skills like memory and attention. Researchers will use a virtual reality game and standard tests to measure brain function in 42 adults with severe obesity before and after surgery. The goal is to see if losing weight through surgery leads to measurable improvements in cognitive performance.
