What Is Cardio-Metabolic Depression?

What's the link between mood disorders and obesity or insulin resistance? Susan J. Noonan, MD, MPH, shares what she learned at the 4th annual Precision Psychiatry .

There, Roger McIntyre, MD, FRCPC, presented on what he calls "cardio-metabolic depression." According to research, mood disorders like MDD or bipolar disorder seem to have a connection with insulin resistance or obesity. Patients who have metabolic obesity are more likely to have insulin resistance and impaired cognition. While the exact mechanism is unknown, GLP-1 agonists may have a promising antidepressant effect in a subgroup of patients who have cardio-metabolic depressive disorders.
