96. Hormones and Depression: Why SSRIs Are Not the Full Answer

Think about how many of your patients walk in with the same story. Low mood. Zero motivation. Brain fog that will not lift. They feel like a different version of themselves, and nothing they have tried has brought them back. You run a standard panel. Everything comes back normal. And the next step in the algorithm is an SSRI.But here is the question nobody seems to be asking: did anyone check their hormones?In this episode, Nico Misleh, MSN, FNP-C challenges the framework that has dominated depression treatment for three decades, the idea that depression is a disease caused by low serotonin. He walks through Dr. Joanna Moncrieff's 2022 umbrella review that found no consistent evidence linking serotonin levels to depression, and then builds the clinical case for why testosterone, progesterone, estradiol, and thyroid should be among the first things you evaluate in a depressed patient, not the last. Testosterone drives dopaminergic function, motivation, and cognitive clarity. Progesterone converts to allopregnanolone, a neurosteroid that modulates GABA receptors, the same calming pathway that benzodiazepines act on, without the dramatically ill effects. Estradiol upregulates serotonin receptors and modulates dopamine in the prefrontal cortex. When these hormones are deficient, the clinical presentation looks exactly like major depressive disorder. And putting that patient on an SSRI without checking any of them is the equivalent of treating chest pain with tablets without ever running an EKG.The HRT University Master Course is jointly accredited through Pinnacle Conference LLC (ACCME, ACPE, ANCC) and offers 30 CE credits across six modules covering metabolic foundations, male HRT, female HRT, advanced female endocrinology, thyroid optimization, and adjunct hormones.Explore the Master Course: https://bit.ly/4twBb0DJoin the Free Newsletter: https://nicomislenp.kit.com/8050eeea5fFacebook Community: https://www.facebook.com/groups/1179376819949373/Website: https://hrtuniversity.comFollow HRT University on Instagram: @hrtuniversity
