Why The Serotonin Imbalance Story Does Not Hold Up In Research

Antidepressants are treated like a settled science, but the deeper you look, the more the details matter. I walk through what big meta-analyses have found when antidepressants are compared to a standard placebo and then to an active placebo that makes people feel like they got the real medication. That distinction changes the story, especially when we ask who benefits most and how large the medication-specific effect really is for the average person. We also take on the serotonin imbalance narrative head-on. A major 2022 review in Science examined hundreds of studies that aimed to prove a serotonin deficiency model of depression and found the evidence just doesn’t support that simple explanation. If the “chemical imbalance” message is shaky, it affects how we think about informed consent, expectations, and what it means when someone feels better after starting a prescription. The placebo effect becomes part of the conversation, not as an insult, but as a powerful reminder that belief and context can change symptoms across many areas of medicine. From there, we talk about what can happen months or years into antidepressant use: dose increases, switching meds, stacking medications, and the very real fear of coming off because side effects and withdrawal can be rough. I also share how we approach depression and anxiety at Capital District Neurofeedback by using neurofeedback to help change the brain in more predictable ways and support lasting improvement. If this challenges what you’ve been told about antidepressants, subscribe, share this with someone who needs it, and leave a review with the question you want answered next.
