Conditions studied: Obesity, Memory Deficits

In brief

1. Briefly describe the purpose of this protocol. First purpose of the study is to understand the inheritance of morbid obesity. 2. Briefly summarize how participants are recruited. Volunteers will first learn of LABS-2a research opportunity at the Bariatric Surgery Informational meetings. 3. Briefly describe the procedures subjects will undergo. Participants will be asked to complete a set of memory tests. Fat and Liver samples will be removed during their weight loss surgery, specifically for this research study. 4. If applicable, briefly describe survey/interview instruments used. Memory tests will be performed to assess cognition. 5. Briefly describe how the data will be analyzed to address the purpose of the protocol. The memory test data collected and compared against well established norms. Tissue samples will stored in a repository to be genetically studied for an indefinite amount of time. Genetic studies will be related to the disease of obesity and associated comorbidities brought on by the disease.
