Inflammation may hijack the Brain's reward system in depressed women

NCT ID NCT03848715

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looked at how inflammation affects the brain's reward system in 40 younger women with depression. Participants received either an endotoxin (to trigger temporary inflammation) or a placebo, and researchers measured changes in how they responded to rewards like money or smiling faces. The goal was to better understand the link between inflammation and depression, which could help identify new ways to intervene.
