The psychiatry profession has finally come clean and confessed on a national media outlet that there is no evidence to support the Serotonin Theory of Depression. Today, on NPR’s Morning Edition there is a segment about the chemical imbalance theory, and virtually all the psychiatrists who are interviewed acknowledge that the there was never any evidence in support of the idea that low serotonin causes depression. But then, amazingly, they go on to say that it is perfectly fine to tell patients that serotonin imbalance causes depression even though they know this isn’t the case.
Several years ago in PLoS Medicine we wrote a long piece about the serotonin theory and the disconnect between what research psychiatrists say in professional journals and textbooks and what the advertisements say. While the advertisements presented the theory as scientific fact, the scientific sources clearly did not. Given the enormous marketing programs that pushed this theory combined with the media’s lack of skepticism, we were sympathetic to the general public who could hardly be faulted for thinking that theory had some foundation in fact. Following the publication of our piece a reporter contacted us and suggested that we were attacking a well accepted theory. We pointed out to the reporter that we weren’t attacking a sacred cow but that instead we were pointing out the mainstream psychiatry didn’t even accept this theory. We urged the reporter to contact the FDA, NIMH, APA, etc and ask them about the science behind the advertisements. He did, and as expected, an expert from the FDA explained that the theory was really just a metaphor. The problem is that patients who heard their physician explain the serotonin theory thought they were hearing real science. They weren’t told it was a metaphor and hence thought it was a fact. When a doctor talks about high cholesterol, diabetes, or hypothyroidism, they are talking about scientific measurement, not a metaphor. How is a patient with high cholesterol and depression who listens to their doctor’s explanation of their conditions supposed to know when the doctor has moved from science to metaphor?
