About this trial
The goal of this study is to determine if weight loss or changes in dietary intake can help prevent of delay adults with Down syndrome from developing Alzheimer's Disease
Adults with Down syndrome without dementia will be randomized to either a weight loss group or a general health education control group. The weight loss group will be asked to follow a reduced energy diet, attend monthly education sessions delivered remotely and self-monitor diet and body weight using commercially available web-based applications. The control group will be asked to attend remotely delivered monthly education sessions on general health education topics.
All participants will come to the University of Kansas Medical Center, 3 times across 12 months for a blood draw, cognitive testing, a MRI, assessment of height and weight, and assessment of diet intake.
