Summary
This study looked at how ghrelin, a hormone released when you're hungry, affects brain chemicals linked to motivation. Researchers gave ghrelin or a saltwater placebo to 26 healthy adults and people with depression, then used brain scans to measure dopamine activity and motivation to work for rewards. The goal was to understand if boosting ghrelin could help treat low motivation in depression.
