Who could benefit from this research
✓Could help
Ideal participants are adolescents aged 12-20 with obesity and adults 21+ with obesity who are willing to receive GLP-1RA treatment and participate in brain imaging and behavioral assessments.
✕Less likely to help
Some individuals may experience limited weight loss or side effects from GLP-1RA treatment, and not all will respond.
What this research studies
This project explores how a class of diabetes medicines, GLP-1 receptor agonists, changes brain activity related to hunger and weight control in teens versus adults. It will use brain imaging and behavioral assessments to understand differences during adolescence, a time of heightened neural plasticity. The study will examine changes in brain circuits that regulate appetite and measure weight loss and appetite sensations over time. By comparing adolescents to adults, researchers hope to identify age-specific effects that could guide future obesity treatments.
Why it matters
Potential benefit: If successful, teens and adults with obesity could receive more effective, brain-targeted treatments that support weight loss and healthier eating behaviors.
How similar studies have gone: Previous studies show GLP-1RAs can cause weight loss, but this study uniquely compares adolescent and adult brain responses.
