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.

Dispelling the myths about antidepressants. There were two meta-analytic studies, these are huge studies, that looked at the impact of antidepressants about 10 years ago and another one about eight years ago. Both of these studies found the same thing, and it was essentially this. Antidepressants work fairly well when we compare it to a sugar pill, a placebo that has no effect. But compare it to a lie placebo, a drug that makes the person think got the real McCoy, so to speak, we see that antidepressants make a difference for about six, maybe eight percent of the population. And these are the folks who are severely, severely depressed, often comatose depressed. So that data has been out there for quite a while. Also, then in March of 2022, a really seminal study came out in Science Magazine, which looked at over 300 studies which tried to prove the serotonin deficiency theory behind antidepressants correct. Most of these studies were conducted by the pharmaceutical industry. And in that summary journal article, they concluded that not one of the studies demonstrated that there was a serotonin deficiency involved with antidepressants. Now, do a lot of people feel better after taking it? Yes, no doubt. You may be one of those folks. But what we do know is if we give individuals, adults, children a sort of li placebo, something that kind of creates symptoms similar, we get almost identical effect. So it is the belief in that medication that is really making the big difference. And yet when we believe, we know that there is power in belief. However, the challenge becomes that uh when we look at antidepressant medication, if many of you went down this path, six months or a year later you're you're going, oh, I'm not feeling quite. Oh, let's give you a little more. Oh, let's try this one. Oh, we can add this, it's gonna amplify what's happening. And so the sort of story goes on in ways to keep feeding this methodology, which is now well proven that there is no serotonin issue that's involved in depression. And thus a lot of this is based upon the public believing in it. Now, if you have any question about the power of placebo, it is worth doing your research. Whether we look at surgeries or whether we look at medications, we look at cancer treatment, we see over and over again, if I believe, if I believe in the treatment, the treatment is likely to make things better. And yet, over time, what we see with antidepressants is six months, a year, three years, ten years. You look at somebody who's on an antidepressant and you ask them if they're happy, unlikely that you'll get that they're happy. They're afraid to come off of it because the side effects are so horrendous. It has to be done carefully. Here in our clinic at Capital District Neurofeedback, we often help our clients either get off of medications or if they're off medications, we help them with depression. Because with neurofeedback, we're able to actually change the brain in predictable ways to improve that brain's performance and to actually help folks get happier and find more ease and less anxiety in their life. But if you're interested in this issue of antidepressants and their effectiveness, just search for meta-analysis of antidepressants. You'll find one large study done here, one in Europe. You'll also in March 22, uh, 2022 find that science journal article which reviews the mythology of the serotonin uh effect of antidepressants. Alrighty. Well, if you have questions about neural feedback and how it can help you or someone in your family, just give me a call or set up a free consult. You can do that on my website. No charge, you just get to ask questions. I hope you find this helpful. I'm Dr. Randy Cale. I look forward to chatting with you perhaps. Take care, I'm not sure.
