Depression
Investigational / off-label
Last updated 2026-07-12 06:04 UTCResearch on GLP-1 drugs and depression shows mixed findings, including reports of both antidepressant effects (e.g., neurogenesis enhancement, improved memory performance) and associations with suicidal ideation or psychiatric adverse events in some studies and pharmacovigilance analyses.
