NCT ID: NCT01815216 Suspended - Obesity Clinical Trials

Effect of Gastric Bypass Surgery on Brain Responses

Start date: March 2013
Phase: N/A
Study type: Interventional

After obesity surgery gastric bypass (GBP) patients usually lose more than 50% of its former preponderance in relative short time (~ 2 years). But knowledge of the underlying biological mechanisms of decline in body weight is still inadequate. This project intends to examine patients' background activity in the brain (i.e. "the resting state activity") and brain volume using MRI both before and one year after surgery.
