What evidence challenges the chemical imbalance theory of depression?
There is no evidence that you have a chemical imbalance in your brain if you are depressed. So therefore, there's no evidence that that antidepressant you're being offered is going to correct that. They haven't asked that question about what antidepressants might be doing by just messing about with our normal brain chemistry. If you subscribe to this idea that you have a brain chemical imbalance, you actually do worse. You have worse outcomes. The psychiatric profession really seemed to me to just want to shut down the debate. They didn't want people to get an inkling that actually depression has not been proven to be a biological condition.
How prevalent is antidepressant use in society?
How many people in our society are on these drugs?
So it's something like 8.7 million people in England who take them.
In England?
In England.
So one out of five people of the adult population is on antidepressants.
Almost one out of five are taking antidepressants, which is absolutely staggering, isn't it?
Joanna Moncrief, welcome to Trigonometry.
Thank you for having me.
What are the historical misconceptions about depression?
Oh, it's great to have you on. You're one of the people who was instrumental in challenging what is the effective consensus on depression, the idea of it being that it's the product of a chemical imbalance, which is something that was, I think it's fair to say, effectively debunked in the last couple of years. So what is depression and why do we have this false idea of it?
Well, I hope I've debunked that idea, but I think it's actually still quite prevalent. You can still find it on websites and things like that, that depression is caused by lack of serotonin or whatever. So we've had this idea since the 1990s that depression is caused by an abnormality, an imbalance of brain chemicals. Before that, people used to think of depression as a reaction to bad circumstances, you know, unemployment, divorce, child abuse, childhood trauma. And they saw it as an understandable reaction. Of course, there would be variations between different people. Some people would react more strongly to being made redundant than others. But fundamentally, it was an understandable human reaction.
And then in the 1990s, The pharmaceutical industry released a new range of antidepressant drugs. They wanted to persuade people to take these drugs rather than the old benzodiazepines, which were prescribed for anxiety and which had got this really bad reputation because they caused quite severe dependency problems.
What does the latest research say about serotonin and depression?
And so to distinguish these new antidepressants from the old benzodiazepines, they persuaded people. They put out this idea, basically, that depression is a medical disorder that is caused by an abnormality in the brain, specifically a deficiency of serotonin, which their new drugs happen to be able to put right. So that's where the idea comes from, this idea that depression is this medical condition. But it was superimposed onto people's underlying sort of intuition about what depression was, which was quite different.
And the sort of undercurrent on what you're saying is this was a for-profit motivation that caused this to happen.
Yes, yes. I mean, that idea that depression was caused by a chemical imbalance, an abnormality or deficiency of brain neurotransmitters was around. It was first proposed by psychiatrists and researchers working in the 1960s. Again, in the context of developing drugs for emotional problems. But it wasn't sort of widely accepted, certainly among the general public.
How do SSRIs work and what are their effects?
And so it was the 1990s when the pharmaceutical industry got involved and conducted these very thorough promotional campaigns that really spread this idea. And yes, of course, they did it in order to sell more drugs.
And what does the evidence show about this? Is there any evidence to support the chemical imbalance theory? And if there isn't, what is the evidence telling us about what depression is and where it comes from?
So I did a big review of the evidence, which was published in 2022. And I wrote my book because of the reaction we got to publishing that paper. the astonishment of lots of members of the public and the media that actually there wasn't good evidence for this theory and pushback from the psychiatric profession itself.
