Objective:

To evaluate the association of GLP-1 receptor agonists with psychiatric outcomes in patients with depression or anxiety receiving noninsulin antidiabetic therapy.

Key Findings:
  • Semaglutide was associated with a 42% lower risk of worsening mental illness compared to nonuse.
  • Liraglutide showed a more modest reduction in risk.
  • Exenatide and dulaglutide did not show a difference in risk.
  • Semaglutide was linked to lower risks of worsening depression, anxiety, and substance use disorder.
  • At the class level, GLP-1 receptor agonists were associated with a lower risk of self-harm.
Interpretation:

The findings suggest that semaglutide may have protective effects on mental health in patients with depression or anxiety, while liraglutide also shows some benefits.

Limitations:
  • Causality cannot be established due to the observational nature of the study.
  • Lack of data on symptom severity, body mass index, and glycemic control.
  • Limited statistical power for less frequently used agents.
Conclusion:

Semaglutide and, to a lesser extent, liraglutide are associated with significantly lower risks of worsening mental illness in patients with depression or anxiety.
