In short

Over-diagnosis and over-medicalisation—when medical labels, screening, and tests do more harm than good, even if the diagnosis is technically correct.

Guest background

Dr Suzanne O’Sullivan is an NHS neurologist with 30 years’ experience and author of The Age of Diagnosis, which argues that people and clinicians must weigh diagnosis trade-offs.

Key claims

  1. Over-diagnosis is not misdiagnosis; it’s identifying the point where diagnosis causes more harm than benefit.
  2. Harms come from “classification/nocebo effects”: mild symptoms get amplified, people undergo unnecessary scans/tests, and anxiety can redirect life.
  3. Over-detection arises from excessive screening and from advanced technology (e.g., MRI, rapid genetic testing) that finds abnormalities unlikely to matter.
  4. Population-level evidence is needed; individual outcomes can look “successful” while overall all-cause mortality doesn’t improve.

Notable examples

  • Stephanie and her daughter Abigail: a genetic epilepsy/walking condition was found after years; the diagnosis clarified cause but may have stolen “healthy years” and shifted identity toward illness.
  • Cancer screening: JAMA all-cause mortality findings suggest cancer screening reduces cancer deaths but often doesn’t reduce all-cause mortality because many treated cases were never destined to become lethal.
  • Prostate cancer: high rates of abnormal cells (Detroit postmortems) make PSA screening prone to over-diagnosis; solution proposed includes screening high-risk people and distinguishing “screen-detected” from symptomatic cancers.
  • Neurodiversity/ADHD/autism: rising diagnoses reflect broadened criteria (DSM changes), not necessarily more autism; late diagnoses can validate but may also limit identity and expectations.
  • Valentina/Huntington’s: she avoided genetic testing for ~20 years to protect her children and preserve hope; later symptoms were real, but her brain’s expectations shaped perceived decline; test was negative.

1:46Amol Rajan:Hello and welcome to Radical. We have got an absolute cracker of an episode for you today. Look, what we try and do, what I've tried to do actually for quite a long time now, is to shift some of the focus of public conversation, especially in the news industry, from events from the here and now to the deep underlying trends. And my guest today is someone who has spent 30 years in neurology, understanding our brains as an NHS doctor and writing books, which have been read by a huge number of people about those trends as they pertain to medicine and public health. She is Dr. Suzanne O'Sullivan, most recently the author of The Age of Diagnosis, and she thinks that we are getting diagnosis wrong, basically because we're doing too much of it.

2:30Amol Rajan:She wrote this book because she thinks that we all need to think much, much harder about the trade-offs that are involved in getting a diagnosis. Diagnosis is wonderful. It's an important stage in treating people who are not well. It offers clarity and maybe a bit of catharsis, but also a path to a better future. And yet, diagnosis, in ways that, to be honest, I hadn't really thought much about before I started reading her book and preparing for this conversation, diagnosis has trade-offs. It has trade-offs at the individual level and at the social level. And if we have a society which, as she sees it, is both being over-diagnosed and over-medicalised but not actually getting much better, Well, maybe we need to think a bit harder about what diagnosis actually involves.

3:14Amol Rajan:I should say as well, when I put out a punt for questions on social media, lots and lots and lots of you got in touch. She answers your questions in our bonus episode, which is going to come out on Monday. But I've also tried very hard in this conversation, not only to swat up on the science, but to make sure that in a way that is fair, accurate and impartial, we put the appropriate pushback and scrutiny to her positions. And as you'll hear, she engages very meaningfully with all of that.

3:45Amol Rajan:Dr. Suzanne O'Sullivan, welcome to Radical Thank you so much for having me on Can I start off by saying I think there's a couple of really important sort of, as it were, clarifications which will help people understand what we're going to talk about We're going to spend the first half of this really sort of laying out your argument and then the second half testing it and I think that there's a kind of very important misconception that we should address right at the beginning which is that people should know overdiagnosis is not the same thing as misdiagnosis. Could you just explain the difference please?

4:17Yeah so I think it's absolutely crucial because I think when the general public hear the word overdiagnosis very often that's kind of assumed to mean people are complaining about nothing, that there's nothing wrong, that the diagnosis was wrong. That's very much not what it is. So overdiagnosis is just trying to identify the point at which a medical diagnosis does more harm than good. When I wrote The Age of Diagnosis, I started with a story that I hoped would help people to understand this issue. So a story of Stephanie and Abigail. Stephanie is a patient of mine. I've known her for over 20 years.

4:54She developed epilepsy when she was in her 20s, I think. Nobody really knew what was causing her epilepsy.

5:01Amol Rajan:Epilepsy is one of your specialisms, I should say. Yeah, so I'm a specialist in epilepsy and she came to see me after seeing lots of other doctors. She saw me. I was able to confirm the diagnosis, but I'll be absolutely honest. I've failed to make her better and I'm still failing to make her better. I never really understood what was wrong with her. And then I think it was about 10, 15 years into our journey together, we realised she was having difficulty walking. And I'll admit again, I didn't know what the cause of this was. I'm not coming across as a great doctor at this point, but this neurology is a very difficult, you know, we struggle a great deal to explain a lot of the diseases that we work with.

5:41Then one day in a conversation with Stephanie and her husband, her husband made a remark that just kind of opened the whole kind of mystery up to be explored. He said, Stephanie walks just like Abigail. Abigail was her 15 year old daughter. and Abigail I learned who I knew about Abigail. I understood Abigail to be perfectly healthy child, but I learned that she was teased in school for having a funny walk. Other kids called her the penguin. She was not bothered by this. She was just a very pragmatic young woman. You know, if she couldn't run, she went swimming instead, for example. But the minute I heard this bit of information, it really was the sort of thing that neurologists just love and doctors love.

6:22you know here is a little clue to what might be going on with my patient if mum has difficulty walking and the child has difficulty walking well maybe I'm dealing with a genetic condition it took quite a long time then for us to kind of unfold the actual cause but what I did I regretted for many years after which is having learned that Abigail had this funny walk as her parents described it I sent her to a neurologist along with her mother they had loads of genetic tests and it was revealed that they had a genetic condition that causes epilepsy and walking difficulties. Now, this is sort of just a perfect example of overdiagnosis, because on the one hand, I'd done exactly what I'm trained to do.

7:03I had found the rare diagnosis. I'd found the explanation. I'd got an advanced diagnosis for this 15-year-old girl so she wouldn't have to go on the medical kind of odyssey that her mum had gone on. I should have been celebrating. But after the fact, I just thought, well, what kind of favor did I do this 15-year-old child? You know, this was an untreatable genetic condition. Yes, I had saved her having lots of tests in the future, but I'd also potentially done what overdiagnosis does, which is I'd given her a diagnosis before it was necessary when it wasn't really going to move her life forward in any really positive way.

7:43So I could potentially have changed her entire relationship with her body. She could have, This walking difficulty that she didn't even worry about at all could have suddenly become the focus of her anxious attention. She could have started focusing on the things she couldn't do. So instead of just thinking of herself as a girl who's great at swimming and yoga and terrible at running, she might have started thinking of herself as a girl who's terrible at running. And that's the problem with an unnecessary medical diagnosis is, yes, a diagnosis brings a little bit of help for some people or a lot of help for other people.

8:16but it also bring harms. And that's what overdiagnosis is, when the harm outweighs the benefit.

8:22Amol Rajan:The diagnosis, the appeal of diagnosis is that in times of difficulty, it provides some sort of catharsis. It provides clarity. It provides potentially some certainty, but it also provides a route to getting better. Isn't the cost of overdiagnosis, even in that particular case, worth it because it comes from a prevailing scientific effort and cultural effort to understand why things are going wrong and why people aren't feeling well. I think that's certainly the way people think about it, but I doubt it. I mean, people think that an answer is better than any answer is better than no answer. But the difficulty is that if you diagnose somebody with, say, a genetic condition, and now a lot of people are potentially learning of risks of things like Alzheimer's through genetics.

9:14So this is becoming commoner. If you make that diagnosis and the problem is untreatable, then you are instantly turning someone into a patient who is not yet a patient. And I put it in a kind of quite a crass way. When you turn someone into a patient, they can begin acting like a patient. So what you can do is, let's say that Abigail was 15 when she got her diagnosis and she might not have had any medical problem that actually needed treatment for another 15, 20 years. But I could have, with that medical diagnosis, stolen those 20 years. And it's that I think we underestimate in this conversation, the value of hope and the value, you know, if you're 15, you're dreaming about what will I be?

9:58What will I do? What kind of family will I have? Where do I want to travel? I could have stolen all those dreams from her.

10:04Amol Rajan:So can I start with another sort of, just as we get going, the The misconception which you want to address, which is that you're saying over diagnosis is a problem. It's not about misdiagnosis. You're not saying we shouldn't get things wrong. You want things to be right. You just want an assessment of the trade off. But that sort of presupposes something else, which is that one of the arguments of your book is that we've because diagnosis of severe diseases has been incredibly useful and has formed an industry. People think diagnosis of mild diseases is also useful. and actually the second part doesn't necessarily follow the first.

10:40Amol Rajan:Is that right? Yeah, I think that's precisely right. I think, you know, so we've had this kind of thirst for diagnosis, which is based on really good intentions and assumptions that sound really sound. So if you can... You want to make people better. That's what you do as a doctor. Precisely, you find diseases and you treat them. And we think that that works the same for everybody. and it sounds great in theory but it doesn't it hasn't worked out so great in practice so if you I always think of it as a kind of a harm benefit ratio of diagnosis if you take someone with a symptomatic disease which is disabling them so they can't function as they would want to or they can't function in society then the benefit of treatment is huge because that person is not able to function normally they have symptoms they need help the harm of that diagnosis is quite small because if you're already not functioning normally, you know, that effect of labeling or turning a person into a patient is very small because they already are apparently ill.

11:40They are already apparently not functioning. So the label isn't terribly important. But if you accept it in a positive way to help them access treatment. But if you take people at the other end of a spectrum where their symptoms or difficulties are very minimal, so they're not terribly apparent and they're not necessarily getting enormously in the way of life, then what that person stands to gain from the diagnosis is quite small. But they are precisely the people who can be harmed by what I would call the classification effect or the nocebo effect. You can call it lots of different things. That's where you've got mild difficulties.

12:16Now you've given them a medical name and that medical name can focus lots of attention on the symptoms, reinforcing them. It can also send people on a trajectory to scans and tests and things that will lead nowhere. So again, we're back into this kind of area of stealing people's healthy years with tests and labels when it wasn't necessary.

12:37Amol Rajan:Just before we come back, I want to come back to nocebo. It's such an interesting idea. I have to say I wasn't familiar with it before. Lots of people will be familiar with the idea of placebo, of course. Nocebo is something different. Just before we come to that, there are two other overs which I want to talk about. There's overdiagnosis. There's also overmedicalization and overdetection. overdetection. These all obviously the Venn diagrams intersect but just tell us what you mean specifically with over medicalisation and overdetection. So these are the sort of two ways that overdiagnosis most often arises.

13:02So overdetection arises by two means really. First of all through excessive screening for health conditions. So I guess in about the 1970s we began trying to keep people healthy by finding diseases and disorders at the earliest stages so we actively seek out problems, which means we're finding problems in milder and milder and milder forms. But the milder a form you find something in, the more likely you are to mistake something normal for a disease. The second way that over detection occurs is with our amazing technology. You know, you used to, you know, the very first whole human genome, it took 13 years to sequence it.

13:41We can now do the same sequencing in a day. So we can find genetic problems like in a day, which is incredible. And we've got MRI scans. I was a junior doctor in the 1990s. The MRI scan just came in then. Now we have generations later MRI scans. Until we got those, we didn't actually know what the inside of a healthy human body looked like because you don't investigate healthy human bodies. So we've got all these amazing ways of looking at the body now. And that means we are over-detecting. We're finding things that probably would never have cause problems if we didn't find them.

14:14Amol Rajan:What is the nocebo effect? So everyone's familiar I think with the placebo effect or most people are which is that you know the if you believe a treatment will work it can alleviate your symptoms and that actually which always amazes me a little bit is that even works even if you know something is a placebo you can get relief from it. The nocebo effect is the exact opposite so if you believe that something might make you sick then you may begin inadvertently experiencing symptoms of illness. And I think, you know, examples of it are everywhere. You know, if you were eating your dinner in a restaurant and you turned around and you saw the chef coughing into the next meal that he was about to serve, you know, what's the first thing that happens is you feel sick or if you know you've been exposed to a particular infectious disease, that's a very powerful way of kind of examine, you examine your own body for symptoms or difficulties and then you immediately start noticing things.

15:08So nocebo effect is really the power of the mind to kind of misinterpret bodily changes for abnormal and mistake them for symptoms so that you feel sick. And that's one of the biggest causes of concern for labeling, giving people medical labels.

15:24Amol Rajan:So the question of whether or not something is an overdiagnosis rests on whether or not the diagnosis itself, not whether it's correct or not, but whether or not it does more harm than good. Isn't there a kind of epistemological problem here, which is that you can't know before you've done it, whether it causes more harm than good? You have to sort of live out the 15 years. You are precisely right. And that's why I think this problem is continuing to accrue in every single aspect of medicine. So I think often when you talk about over-diagnosis, people just think about mental health problems because that's the kind of area in which we talk about it most.

15:57And I think I didn't define over-medicalisation, which is where we sort of apply medical labels to normal human experiences. But actually, overdiagnosis is happening in every field of medicine for precisely the reason you say. Fifty years ago, we decided we'd screen more people. We got better technology that allowed us to screen people more carefully. We began looking for mental health disorders in milder and more atypical forms. And because at the point at which we diagnose people, it all seems to be going swimmingly. So if you diagnose someone with very asymptomatic, small abnormal cells that look cancerous and you say they're cancerous based on your experience and then you treat them and that person doesn't die of cancer, well, then fantastic.

16:45Then you've reinforced your own belief that you're doing the right thing. And it's similar, I think, with the expansion of mental health labels. They often come and feel very validating in the moment. and therefore both patient and doctor and scientist feels like it's all going great and that something very positive is being done. It is very, very hard to measure over-diagnosis in that individual way. I think the way that you can spot it is by looking at populations. So if you look at what's the reason for much more cancer screening and doing much more tests and looking for something like cancer is that down the road you prevent cancer deaths.

17:24So we should all be much healthier as a result of these screening programs. And similarly, if we screen for and find milder forms of mental health problems, then somewhere down the road, we should be seeing a very positive impact on the population. We're all much mentally healthier and suicide rates are going down. I think that's the difficulty in spotting overdiagnosis, why it isn't being spotted. But I would say if we look downstream at populations, I'll give you kind of a more scientific example. So there was a good study in the Journal of the American Medical Association looked at all cause mortalities in people undergoing cancer screening.

18:00So if you look at cancer screening, you can look at cancer deaths. And obviously, if you're screening loads of people for cancer and treating every one of them, you would expect cancer deaths to go down. And they do. But then if you look at something else called all cause mortality, deaths for any reason, what you find is most cancer screening programs don't save any lives at all. And it seems very counterintuitive. But the likely reasoning for this is that if you screen lots of people for cancer, you will save lives for sure. But for every life you save, maybe something in the region of 10 people will be treated for cancer who never needed to be treated.

18:39Amol Rajan:So this was the thing that I found most revelatory about your book and the argument that you've made. And obviously I've done a try. I'm not going to pretend for a minute to be some sort of medical expert, but I've tried to understand the science of what you've been saying. Take prostate cancer. A lot of high profile men get prostate cancer. A lot of men get enlarged prostates. And some people's enlarged prostate is confused for cancer. and a lot of famous men with access to microphones, which have millions of people at the other end of it, get prostate cancer. And people who are in that category include, for instance, David Cameron, former Prime Minister, Steve McQueen, the brilliant director.

19:17Amol Rajan:He's black and I think, I don't know if he had it or someone in his family had it, but I think black men are more likely to get prostate cancer. Rishi Sunak, the former Prime Minister, has not, as far as I know, had prostate cancer, but he's a big advocate for early screening, as is Nick Jones, who's the founder of the Soho House. members club and a very successful businessman and they have been very public in asking for more prostate cancer screening what's what's the argument against that okay so there's a reason that we don't have standard prostate screening because um the rates of medical over diagnosis with it with the current type of prostate screening is incredibly high so if i give the example of a study that was carried out in detroit where they looked at men who had died in accidents and various things not prostate related.

20:03And they did postmortems. In men over the age of 50, 45 % of them had abnormal cells in their prostate. And in men over 60, 70 % had abnormal cells in their prostate. So what we're learning...

20:15Amol Rajan:So just because that's not the same thing as cancer. So they had abnormal cells that if they had been screened for cancer could have been mistaken for cancer. So the problem is... But they didn't necessarily have cancer. Well, this is the problem, is we're not very good at determining... So we find these abnormal cells. We've got this amazing technology now that allows us to find abnormal cells at a very early stage that are asymptomatic in people, in breasts, in prostates. And when we find these abnormal cells, we cannot easily distinguish the ones that will grow into a malignant life-threatening cancer and the ones that will just sit there for the rest of your life and you would never have known they existed if you hadn't been screened.

20:54But we call them all cancer.

20:56Amol Rajan:And do we treat lots of people? Are you saying that 10 times number you came up with a moment ago? Are you saying that we treat 10 times, we treat for every one person we correctly identify as having, say, prostate cancer, we treat 10 men in this case for prostate cancer that don't have prostate cancer, they just have abnormal cells? Yeah, exactly that. So let's say for breast cancer, a Cochrane review, so a Cochrane review is a review of all available evidence, looked at 2 ,000 women screened for cancer and estimated that you save one life from breast cancer when you screen 2 ,000 women, but you treat 10 other women who never needed to be treated.

21:36And that's pretty much the same for most cancers that are subject to screening. It's particularly high in prostate cancer. So it is the part of the health economics that scientists have accepted is that when you screen for cancer, you will treat some people who never needed to be treated. And we're taking a long time to figure out how many excess people have to be treated to save one life.

21:59Amol Rajan:So on your point that you can have over-diagnosis and under-diagnosis, does that explain why there might be, would that justify policy and funding discrepancies in the treatment and screening of different cancers? For instance, just from this weekend, there was a piece in the UK press saying, researchers say, this is one view, researchers say it no longer makes sense to reject prostate cancer screening on the one hand, while endorsing screening for breast cancer on the other. Dr Sigrid Carlson, who led a study at the German Cancer Research Centre, said, and I quote, if prostate cancer screening were extended to the wider population, then the outcomes are likely to be very similar to breast cancer.

22:36I think that prostate cancer is particularly prone to overdiagnosis because the PSA test that we currently use just isn't that reliable. So prostate, you know, there is a reason that the government does not recommend that we have standard prostate screening with PSA. and that's because so many people would be treated unnecessarily. In the breast cancer, people are also treated unnecessarily, but at lower rates, which is why that has been tolerated. But what I would say is the solution to this is probably twofold. First of all, screening is more useful in high-risk people. So you gave the example of someone who is black who had a family history of prostate cancer.

23:16That's a high-risk individual. If you take somebody with a high risk of developing a disease and you screen them for it and you get a positive test, then you are doing a much more useful type of screening than a type of screening that takes loads of low-risk people and applies the same test to them. So I think the first thing we can do is screen high-risk individuals and that will make screening a bit more meaningful. But I think the other thing we need to do is kind of make some sort of distinction between a cancer found on screening and a symptomatic cancer. So the moment if you go in and you have breast cancer screening and they find some abnormal cells, you will be told that there are cancer cells.

23:58Now, what would anyone do in response to that? You would immediately be terrified and say, you know, give me everything, throw the book at it, you know. Whereas these using the same phrases, using the term cancer for a screened abnormal cell and symptomatic cancers is, I think, problematic. What would be better is that if we had a slightly different name for these screen cancers.

24:21Amol Rajan:That distinction is obviously very, very useful. But just, I mean, without kind of getting into the impossibility of utilitarian judgments, wouldn't, would it be worth 10, to take the example of prostate cancer, 10 blokes being treated wrongly for having abnormal cells in their prostate if it saved one person from prostate cancer? And that in turn depends on whether the one person you save from prostate cancer is your dad or not. And isn't there an upside to over-diagnosis and over-medicalization, which is the social, and obviously we'll come to the downsides as you see them and argue in your book, but that hyper-awareness can make people lead healthier lives.

25:00Amol Rajan:For instance, just to give one example of it, my dear beloved dad died partly of complications of type 2 diabetes. I've been overweight most of my life. I know I don't look at Suzanne. I look incredibly fit and healthy. I was about to say that. Yes, exactly. A rippling torso of extreme physical exuberance. If you're South Asian, if you've been overweight, and if you're over 40, you put in your kind of know your risk score and the NHS thing, chances are me getting type 2 diabetes are high. Watching my dad die with a bunch of tubes coming out of his body during Omicron, I decided to get fit. And this has been a great spur to me.

25:35Amol Rajan:The danger of someone saying you've got a risk of being type 2 diabetes has been a spur to action. Isn't it useful for us to have a better understanding of our potential ailments in the future if it makes us lead better lives now? I guess it depends, first of all, on what intervention you're talking about. So let's say, you know, if we're talking blood pressure screening and the outcome of, you know, again, we're talking similar sort of statistics to prevent one stroke, you treat 150 people. but you know the harm to those 150 people well I would suggest that we neglect it but you know it's mostly people becoming more mindful about their health etc so one can live with that and but can can one live with them having a prostate operation that potentially foreshortens a person's life through complications or causes impotence you know I think we don't we don't think about these 10 people enough.

26:28And it may be that a person would still have the screening knowing that these sort of statistics exist, but I suppose my problem is they don't know. So how many women who go for breast cancer screening or prostate screening realise that they could actually enter what we call a watchful waiting programme, meaning not every cell that you find on screening will grow into a malignant cancer. You don't have to panic immediately like you would with a symptomatic cancer. What you could do is say to your doctor, well, will you do another scan in three months' time and then three months after that? And if this thing is just not changing, then perhaps I'll just wait.

27:06So it's not so much that we should say, well, let's stop screening. We need to be more public about this sort of over-diagnosis, over-treatment. People may still choose it.

27:16Amol Rajan:And give people better information, for instance, about the kind of watchful wait scheme. Can I just ask you just to lay out a couple of other aspects of your argument? And one way of doing this, I want to ask you about the role of the pharmaceutical industry and whether or not we have a generation of snowflakes, which is a term that you usefully avoid. But it's one of the things that people listening to this, I know because they've messaged me, want me to ask you about. Before we get there, one of the arguments of your book and other podcasts you've done is that this tendency towards overdiagnosis, for reasons you're humble enough to admit you don't fully understand, does seem to afflict women more.

27:49Yeah.

27:49Amol Rajan:A couple of possibilities. You say women's bodies are noisier, menstruation's a monthly thing. Why might it be that this is more of a female phenomenon? I mean, I absolutely don't want to pretend that I know the answer, but I certainly think that women are more inclined to sort of be victim to this kind of over-labelling. You call it a gathering of labels. Yeah, and I think a little bit of it is cultural, societal. You know, that women, although things have changed a great deal for women, women have difficulty getting their voices heard sometimes. You know, there certainly is a neglect of women, of conditions that only affect women like endometriosis.

28:29So a way for a woman to be heard is through these labels sometimes. So I think they give a woman a voice and they give an opportunity for somebody to ask for help in a culturally salient way that tracks the kind of help that a person wants or needs.

28:49Amol Rajan:I was going to say perhaps the people with endometriosis would say that seeing it from their point of view, they desperately need that help. And we've not understood the pain that they're going through until recent years. And it's about time, if you think, I mean, when I read about this, I think there's centuries of women who suffered basically in silence, going through terrible pain. Isn't there kind of a social benefit to the fact that we do give salience to those voices and we do say that your hurt means something. Well, I think the, so I'm not saying, by the way, endometriosis is overdiagnosed.

29:19I'm saying that conditions like that that were neglected are an example of the way women's voices haven't been heard. But the solution to that is not to apply as many diagnoses as possible to women so they can now catch up with men, but rather to improve diagnosis and to improve your listening to women. So we don't need really to...

29:41Amol Rajan:You shouldn't require a diagnosis for that voice to be heard. No, that's what I don't understand is why do we need it? One other aspect of this is pharmaceuticals. To what extent is it the case, there are people who think this, that over-diagnosis and the move towards medicalisation is a problem of capitalism rather than culture? In other words, a few mostly very big, very powerful firms stand to gain enormous amounts of money from medicalising everyday life. Do you know, people always ask me about pharmaceutical companies at festivals and things. And I always kind of, I am not someone who believes that there's some terrible great capitalist conspiracy that has caused this.

30:22I'm not saying the pharmaceutical companies play no role whatsoever, but I would consider them opportunists rather than the cause of this problem. So if you look at it doesn't matter, there's no drug for autism, but autism diagnosis are growing exponentially. So you don't need a pharmaceutical company to be there for this to happen. I think that it's much more come from a scientific medical drive to find more diagnosis that is then being met by people desperate for answers. And then these people are looping back into each other. You know, I, the doctor, am desperate to give you an answer. So you, the patient, are desperate to get an answer.

31:01And together we've kind of created this situation. And then you have outside forces coming along like pharmaceutical companies who I consider to be more opportunistic on a situation that's been created by society, doctors society and patient society.

31:16Amol Rajan:Let's get into neurodiversity and address it very head on. are more people in say British society in the year 2026 more people neurodiverse by which we actually mean a diverse number of things for instance ADHD and autism are there more people who are neurodiverse or are more people claiming to be neurodiverse who in fact are not so let's just start with this neurodiverse term so that's not a medical term it came from a sociologist who described this idea that, you know, everybody is diverse. And she created the term neurodiversity to kind of give respect to the concept that there are people who are more diverse than others, for example.

32:00So a lot of people now would consider themselves neurodiverse, but that's not medical. But if we look at neurodevelopmental conditions, autism and ADHD, those diagnoses have risen exponentially. I mean, autism used to be diagnosed at a rate about one in 2 ,500 children, let's say 50 years ago. And now it's closer to kind of one in 36 children or one in 100 adults.

32:25Amol Rajan:Why has that rise happened? This rise has happened not because there are more people who are autistic, but because we have changed the meaning and the description of what autism is. So if we go back to the 1960s or 1940s, autism was someone who was described as severe autistic aloneness, someone who was 0 % interested in people, who was nonverbal, who was learning disabled. And then we move into the 1960s and someone said, you know, I think I recognise the characteristics of autism being communication problems and obsessional kind of traits. Inability to make eye contact or preference not to make eye contact.

33:05Or repetitive behaviours. I think I'm seeing those things that you described in these severely disabled children, I think I'm seeing them in less disabled children. And therefore autism became a spectrum that was now being diagnosed in much milder forms. And then we move forward and people say, well, I'm seeing this same traits in people without learning disability who are not, who don't have them, who can speak and are able to communicate. So every kind of couple of decades, we slightly relax what we understand autism to be. And then every time that we get a new edition of the DSM, the Diagnostic and Statistical Manual of Mental Disorders, we slightly relax the diagnostic criteria to allow the diagnosis in people with lesser difficulties, more atypical difficulties in older people.

33:52So we don't have more people with what autism is. We are diagnosing more people because of how we change the criteria.

34:00Amol Rajan:Is that possibly because we massively and radically underdiagnosed it in the past? Do you know, I don't doubt that we've underdiagnosed it in the past. If I think about my own school years, let's say 70s, 80s in Ireland, you know, my class of 120 people, was anybody recognised have any special learning need of any sort? They weren't that I knew of. And there must have been kids who would have benefited if they'd got extra support. So I don't doubt for a moment that people used to be neglected. But we're back into this situation of desperately looking for more and more people in order to correct that neglect.

34:34I would suggest that we've long ago corrected that neglect and we've wandered heavily into over-diagnosis.

34:40Amol Rajan:Isn't it a good thing if they've been accurately diagnosed? And can you see how, even if we might have an urge towards sometimes over-diagnosis, it might be a sort of over-correction for the fact that we're so under-diagnosed these people who desperately needed to know earlier? Let's think about over-diagnosis and this idea, and I hear this all the time, that somebody who's had a terribly difficult life, Like I spoke to a young woman when I was writing this book called Poppy, and she's now in her 20s. You know, she'd had mental health problems since she was 12. She began self-harming when she was about 12.

35:16She tried to take her life, her own life when she was 13. She'd had anorexia. This was in the background of loads of social problems, bullying. She was grappling with her sexuality. She suffered an assault that went as far as police action, etc. So loads of big, big, big things happening in her life and very serious mental health problems running alongside them. She tried loads of different therapies and she didn't find that they helped her a lot. And then her mid-twenties, she got a diagnosis of autism and she felt enormously validated. Now, this is something I hit against all the time is this feeling of validation and understanding and how great it feels to a person.

35:59And I definitely don't want to take that away from anybody. So I don't want anybody who feels validated by a diagnosis to worry about anything I'm saying. If it's helping you, it's helping you. But I still think we have to challenge the idea of being validated by a diagnosis a little bit, especially in younger people. because if your understanding of yourself is through the language of biology and internal brain networks and let's remind ourselves that autism is a neurodevelopmental brain disorder it is a disorder of the brain and if you understand yourself through the concept of a brain disorder that has the potential to be very limiting for you going forward doesn't have the

36:43Amol Rajan:potential to be emancipatory as well i interviewed name drop for a second forgive me I interviewed Greta Thunberg and she's got Asperger's by the way people describe it people say Asperger's and Asperger's and I've looked it up so many times I'm going to say Asperger's she described it as Asperger's she said it's her superpower it's allowed her to have this hyper propensity to focus I cover technology companies for a living I was a media editor for a long time spent a huge amount of time in Silicon Valley Silicon Valley if you ask Bill Gates by the way Bill Gates who kind of said to me she hadn't really said before that he was probably on the autism spectrum You know, people who run big technology companies, including Elon Musk, who's got Asperger's and spoken about it.

37:22Amol Rajan:They sort of celebrate it now. Hasn't some good come of all of this? We sort of, you know, understanding yourself through, as you said, neurodevelopment disorder can also be an emancipatory thing. Because you think as a society, we're saying, great, you've got this special ability. Go for it. So we're back in the territory of like, of course, some good has come. But has the good been outweighed by the harm? And I would suggest it has. I think often in these conversations, we talk about, you know, who has autism now? Anthony Hopkins, Greta Thunberg. Elon Musk. You know, these are exceptional people.

37:57And these are, you know, I don't think that they're very representative of the community. And we now have this, you know, and it's not terribly helpful, I don't think, to, you know, I hear a lot of people who are very successful people in the media industry, in comedy, etc. declaring their diagnosis in a way that is in this kind of superpower kind of language. But you know what is going to happen to the average 16-year-old who's given one of these diagnoses is that they will not become a worldwide famous figure who gets a stand-up comedian tour and a book deal.

38:34Amol Rajan:But why couldn't it be helpful to them? Well, it could be helpful to them, but it could also be harmful. And that's what we need to understand. So what happens to a person who's 16 and you conceptualize their difficulties through this language of a brain disorder, then you are immediately making concrete something that they cannot do. You cannot do it because you have a brain disorder, which immediately makes it feel insurmountable. You can completely change a person's identity. Have you seen that? All the time. I mean, within my own clinical practice, so I'm a full-time NHS doctor and I see people who have complex kind of brain diseases and multiple other diagnoses.

39:16And my own personal, this is anecdotal, but my own personal experience amongst my patients is that these diagnoses lead nowhere beyond that moment of validation. And when I was researching this book, The Age of Diagnosis, every single person I spoke to who had been diagnosed as an adult with ADHD or autism felt enormous validation. They absolutely would not agree with me if we were to have a discussion with me saying, I fear the diagnosis done you more harm than good. But every single person, like this young woman I mentioned a moment ago, Poppy, who got a late diagnosis and felt validated, all sorts of kind of support was given to her on the basis of an autism diagnosis.

39:59She went to college to study marine biology and she was given extra time and different sorts of support. But she ended up dropping out of college anyway because the support really wasn't the answer. These diagnoses, first of all, they're getting in the way of an examination of life. So what Poppy might, you know, Poppy's life was incredibly difficult. And I did not feel that it was very helpful to her to locate her problem as an internal fixed biological problem in her brain, which seemed to distract somehow from the bullying, the assaults and the terrible things that had happened in her life.

40:32And this really worries me is that we are almost kind of, I know that people feel like these diagnoses are relieving them of blame, but I sometimes see it as actually the opposite. You know, it's you are subject to this kind of abuse or this terrible thing happened to you because you are vulnerable because of your brain disorder.

40:52Amol Rajan:You're saying that more people actually don't have this kind of superpower moment a la Elon, Greta, Chris Packham, Bill Gates. more people because with autism Simon Baron-Cohen makes a distinction between um autism as a difference and autism as a disability and I suppose the people I'm thinking of who I've interviewed about this are celebrating their difference and trying to turn it something positive but for other people it's maybe more at the disability end of it and it's something that traps them almost yeah the difficulty is that you know if the minute what you should be saying to a child is this is what you're good at.

41:29But what a diagnosis sometimes says is these are all the things you can't do. It also makes promises to a child that I don't think the world will keep, which is it says now you have this diagnosis, you can go out into the world and say I have these special needs. Can you please change the world to accommodate me? That's a very romantic idea. And I know that in schools it is happening to a certain degree that we give people extra time or we give people quiet rooms and universities that will continue. But will it continue into the workplace. Some people should say, will say it should, it just should.

42:00But unfortunately, a better, I don't think it will. And I would suggest a better way of supporting children is to help them, first of all, if they're bad at certain things, help them to figure out if they can overcome them. And if they can't overcome them, help them to find their place in the world, a place that suits them, rather than asking them the world, giving them the really unrealistic expectation that the world will bend over to accommodate their difficulties.

43:01Amol Rajan:hi this is alex kantrowitz i'm the host of big technology podcast a longtime reporter and an on-air contributor to cnbc and if you're like me you're trying to figure out how artificial intelligence is changing the business world and our lives so each week on big technology I bring on key actors from companies building AI tech and outsiders trying to influence it, asking where this is all going. They come from places like NVIDIA, Microsoft, Amazon, and plenty more.

Puerto Rico has been building it for decades. as a U.S. jurisdiction operating under U.S. federal law, regulatory standards, and market protections. Here, global companies manufacture life-saving medicines, advanced technologies, and critical products at scale. And with competitive tax incentives designed to support investment and expansion, companies don't just start here, they grow here. Not culture or business, culture and business. Puerto Rico.

44:25Amol Rajan:there's a wonderful story in your book about a woman called Valentina who I just wondered if you could recount um uh briefly for us because what you're partly talking about we'll get into the social effects in a moment but you're talking about what individuals equipped with knowledge of themselves can and cannot do when they approach the world and how it too much knowledge almost over diagnosis can make them approach the world in a way that's suboptimal and valentina kind of embodies this yeah so valentina is this incredible woman um when she was 28 she was pregnant with her first child and she discovered that her mother had huntington's disease now huntington's disease for those who don't know is a genetic condition it if your parent has it, you have a 50-50 chance of getting it.

45:09It is a neurodegenerative condition that's really quite distressing to see, distressing to experience. It can often begin with personality change, psychiatric symptoms that are a little bit kind of overlap with human experience, but then get worse and worse. And you get physical disability, you get involuntary movements. And it declines over, say, 15 years until you're at the point where you have a severe dementia, you can't move, you can't swallow, you can't speak and it foreshortens life. Now when Valentina learned that her mother had this condition she instantly went from being a perfectly healthy woman to having a 50-50 chance of getting Huntington's and worse still her unborn child immediately had a 25 % chance of getting Huntington's.

45:54So you can imagine how absolutely devastating that was for her. Now there is a genetic test, she could have instantly had a genetic test to find out if she was positive or negative. She met a genetic counsellor, someone experienced in helping her to understand whether that test would be useful to her, and she decided against it. She realised that if she had the test and it was positive, you know, this was her first child she was expecting, it would massively overshadow this huge experience. So she decided, you know, to live with the hope that it would be negative would be better than living with the certainty it was positive.

46:28She got on with her life. She had a second child. And over the years, she continued to choose not to test because of the implications it would have had for her kids. If she tested positive, their risk would immediately go up. And because she wanted to just enjoy living her life. But over those years, she also began to get lots of symptoms of Huntington's. We've got to keep in mind she'd seen exactly what happened to her mother. so she noticed her mother first had personality change and then Valentina realizes she's getting more sort of easily angered and she starts getting into fights with her husband which she wouldn't have done earlier in the marriage then she began to notice physical changes she's bumping into things she notices she can't plan and she gets easily flustered every time she walks into an airport the multitasking was just too much for her she'd just fall apart it's overwhelming yeah And this kind of, she kept, she could feel these symptoms.

47:24Her sister had identical symptoms and tested and was positive. Valentina was aware that she was declining. She waited until her kids were both 18. So this is about 20 years after her initial learning about her mom. And she realized she was so symptomatic, she was becoming disabled and she really needed to test. and she discussed it with her kids, explained the implications to them and went and had the test during the pandemic. And I mean, it was so moving. She described to me the moment of getting the test results and she went into the hospital. During the pandemic, the doctor was wearing a face mask and she's desperately trying to read the doctor's expression as they come down the corridor.

48:04This moment she's waiting 20 years for, you know, she's been thinking about. It was huge. And then she walked into the clinic room and the doctor pulled down the mask and the doctor started smiling and she knew instantly the test was negative. She did not have Huntington's and every symptom that she thought was due to Huntington's was not. Now, I start the book with that story because it was so powerful and it's so important to me for people to understand how your relationship with your body changes, not just with a diagnosis, but even with the threat of a diagnosis. And this is a real biological phenomenon I need people to understand because I think some people would hear Valentina's story and they would think, oh, she was imagining it.

48:44You know, it wasn't real. The symptoms weren't really there. These were real symptoms that were really bothering her. And the way that these manifest is, you know, our brains are expectation machines. They interpret the world the way we expect the world to be. So if you expect to feel a certain, we're back to the placebo-nocebo effect again. If you expect a certain physical change in a certain situation, you might experience it. And when you start paying attention to your body, there is so much to be noticed that you don't notice when you're healthy. So, for example, everybody fights with their husband.

49:21But, you know, this became something that was really heightened in Valentina's awareness because she'd seen it in her mom as an early sign of the disorder. Everybody hates airports. So she noticed these things. And once you notice them, that heightens them, that activates your body. And you get into a loop.

49:40Amol Rajan:You kind of amplify. It's precisely that. You know, the more you notice, the more you worry, the more you notice and so forth. What's the moral of the Valentina story? The moral of the story is to understand that a diagnosis or a medical label changes your relationship with yourself and changes your relationship with your body. The Huntington's disease community, only about 10 % of people who could have that test have the test because that community have learned that there is great value in living with hope. there is great value in living with the possibility of any kind of future how do you feel about the as it were we'll come back to this sort of scientific um or the pushback from the some parts of the scientific community and other people have been in touch with me in a second but the politicization of your book so did you kind of want when you wrote this book to address the broader issues around for instance welfare and neats and the huge rise in disability and sickness benefit you know my agenda in writing this book is entirely about improving the care for the kind of people i care for you know so i'm a doctor in full-time practice and i see you know i qualified in 1991 but just in the last 10 years i'm seeing increasing numbers of young people people in their 20s getting label upon label upon label and i have no problem with how many labels a person gets if at the end of it their lives are better or their symptoms are better but I just see people accruing labels and they're not leading where they should so I had no sort of political agenda of of any sort and I certainly don't find it terribly useful when we think about sort of the if I get drawn too much into the political agenda because then you know people mistake it for you know oh you want to save money I'm not trying to take anything away from people.

51:30I want better care, not to take anything away from people.

51:34Amol Rajan:I should say, reading the book, you're a doctor. You're a doctor with decades of experience. And I think there is a sort of, I think no one could doubt there's a sort of compassionate, a kind of graceful and caring approach and tone. But there are some people who hate the fact that you're here and the fact that I've invited you on and who hate me for it. And And I feel that it's important to give them their voice. And there are some people who won't forgive it. And by the way, I'm very conscious of inviting you on. We'll gain lots of listeners and we'll lose some as well. And I just want to put to you one kind of, if I may say, typical in the positive sense of it, response.

52:11Amol Rajan:Where some people have said, for instance, to me, they messaged me on Instagram, I'm not going to name this person because they may not have wanted to be named. I'm really sad to see her, as in Suzanne's views, brackets, not expertise in neurodivergence, platformed. By the way, there's a criticism of me there, which I'll address in a minute. I love your show, but she is not an expert on ND neurodiversity. Her hot takes are dangerous. She doesn't listen to ND folks who tell her their lives are better post-diagnosis and instead judges them for being less successful by her measures of being social and ambitious.

52:40Amol Rajan:And this is the bit that bites. Autistic people with no intellectual disability are nine times more likely to die by suicide. So this is not just an interesting take. It's damaging and genuinely dangerous. Let me address a bit of that that's directed towards me. And there are others who said the same thing. So the P word, by which I mean platforming. I find that people tend to use the word platforming when they say you're giving voice to someone who they disagree with. And there's often an argument on a technical or practical issue about, you know, should you have in the room at the same time, someone who has a different view.

53:11Amol Rajan:Just that point about having someone else in the room with a different point of view, it's just not practical. And sometimes I think it's suboptimal. And I think part of the job of journalism is to be informed and apply scepticism and scrutiny. Secondly, I do want to have a huge range of people on this podcast, including people that sometimes really piss off our listeners. And I think there's probably a minority in your case that will be pissed off and others who will approve of it. What about, so I make no apology for getting on people on this podcast who some listeners will disagree with. In fact, I actually, I'm sorry to say, I think there's a virtue to that.

53:44Amol Rajan:And I think that in the world, you're going to encounter people you disagree with. I hope I've applied some scrutiny to what you've said, and I'm going to continue to. What do you say to the argument, A, you're not an expert on neurodiversity, B, you don't listen to neurodiverse folks, and C, you judge them by your measures of being social and ambitious? Yeah. So, I mean, first of all, you know, I am a full-time neurologist. If anyone is qualified to talk about brain disorders, I would hope that I am. Many of my patients have severe autism. I totally agree. I'm not a researcher in autism, but I think something very interesting happened in the last couple of weeks, which was Uta Frith, who's extremely renowned scientist in the field of autism.

54:30I mean, many of the current researchers who are most prominent in this area, you know, were her PhD students. She is sort of the godmother of autism. She came out and expressed similar views to me recently, and she was immediately attacked. So somebody who doesn't like a particular person's point of view will find a reason to attack them, whether they are a very specific researcher in autism or whether they aren't. And I know that people who find my views difficult will find ways to try and undermine me. But I haven't heard any very convincing arguments that undermine my argument. I think that something interesting is raised in when you mentioned about suicides.

55:09I want to make it super, super clear that I'm not arguing that a person who currently has a diagnosis of autism has nothing wrong with them. I'm not arguing, you know, that we're talking autism. You can have a diagnosis of autism and if you don't, you know, get lost, I'm not going to help you at all. I'm arguing that we currently conceptualize lots of different kinds of suffering as autism and that it is the label and the conceptualizing something as a brain disorder that is the potential harmful bit. I would hope that a GP, a psychiatrist, a psychologist, a teacher, a parent, anyone would notice struggling to the level of suicidal intent without a label of autism.

55:50So my argument is not that, you know, I think we mentioned the word a little earlier, snowflakes or, you know, these people are complaining about nothing. I come from a place of assuming that someone's gone to the trouble of getting diagnosis, that that means something is bothering them and they definitely need support. The question I'm asking is whether that support is best served through a medical label like autism.

56:15Amol Rajan:What about long COVID? There's a chapter in the book in The Age of Diagnosis about Lyme disease and long COVID. Lyme disease is a whole other podcast. Let's focus on long COVID. Does long COVID exist? Yeah, so long COVID exists. The question is about the underlying pathological mechanism for long COVID. So I think it's useful for people to understand the kind of how the term long COVID and the condition we now call kind of post-COVID syndrome, long COVID, came about. It came about through a tweet. An Italian woman tweeted something about chronic symptoms in people who had mild COVID and she used the hashtag LongCovid and that was in May 2020.

56:56So this came about through a kind of a social movement in which people who were suffering in the pandemic, who had not been hospitalised, who had relatively mild COVID symptoms, were struggling with significant mental and physical symptoms. They came together as a movement on social media, which began in May 2020 and just took on enormous momentum. The term long COVID kind of sounds a little bit like it might have come from a medical person and that it was a medical concept. But actually, it was a social movement that was seeking to find support for people who were suffering in a different way during the pandemic.

57:36But it quickly found itself in the mouth of journalists and then politicians and then the scientific community. And what we now know is that long COVID is a very significant condition that has caused serious symptoms and disability for some people and that it seems to behave very, very differently to COVID. So COVID-19, it affected people who are older, who had comorbidities, who are often male, and people had a limited range of symptoms with it. Long COVID has a much wider range of symptoms. It affects a different community, you know, healthier people, younger people, less comorbidities, more women, less people with diabetes.

58:27So these are kind of different conditions. And through that, I would say that long COVID has many of the hallmarks of a psychosomatic condition. Now, the minute I say psychosomatic, people will just hear, there's nothing wrong with you. It's a dismissal. It doesn't mean that you weren't really suffering. I, as a neurologist, the sickest patients I see are people with psychosomatic conditions. These are real physical symptoms that arise out of a psychological mechanism. them there's lots of clues that long covid is not for everybody it's probably a mix of things but for a large proportion of people is psychosomatic for example there was a huge study um done in the uk on children and young people 30 000 people studied and they found that there was a greater correlation between loneliness and long covid symptoms than there was between sort of contracting

59:15Amol Rajan:the virus you will have seen in the bjgp which is the home of general practice of family medicine And it's a pretty punchy headline. It says your new book, The Age of Diagnosis, talks about her curious characterization of long COVID as a psychosomatic condition. Let me just, for our listeners, put to you what they say. This is written by a GP, this review. She talks about, as in you, talk about patient activists rather than advocates. And they say, your language is a giveaway. Activists conjures up the image of agitators, disruptors that need to be brought back into line. Advocates are simply people who stand up for people who have no voice.

59:48Amol Rajan:her suspicion about the expertise of patients runs deep. And then it says, the fact is she, Susanna Sullivan, could have found many people involved in pushing research in long COVID forward who are both medical doctors or medical researchers and long COVID patients. She argues that science must take precedence and ignores the huge research literature that makes the case for long COVID, most definitely not being a psychosomatic condition, cherry picking some research that seems to support her view. Yeah, I would say that I spoke to somebody who had long COVID who recovered, a professor of infectious diseases who had long COVID and then sort of really struggled because he was a professor of infectious diseases.

1:00:27He believed that you got an infection and then you just got better. And when he wasn't getting better, you know, he couldn't believe that his symptoms were that bad. And he found a community of people with long COVID and they advised him that, you know, he needed to stop dominating his symptoms and he needed to learn to live with them. and to rest more, etc. And that doctor, though, being a kind of scientist, sought other opinions. So first he followed this advice, which was accommodate to your symptoms rather than dominating them. And then he found a group in Norway called Recovery Norway, and they offered an alternative perspective, which is this hope of recovery through incrementally building up your activity.

1:01:11And he made a full recovery. So I put that story about long COVID in the book, But the difficulty is that he recovered and that's a challenge for some people. That's a challenge for the story of long COVID that says you will not recover. Recovery stories are quite difficult. And this is where I really struggle with illness, some kind of illness activism and also illness identities, which is if your identity is so interwoven to your illness that if you lose the illness, you lose your support group and you lose your identity, then how do you get better? So I told a story of long COVID in the book, but because it was a recovery story, it wasn't considered to be the right story per se.

1:01:55I think the biggest difficulty in this conversation is the minute you say psychosomatic, people just think, oh, well, that's just nonsense. You know, that means you were imagining it, etc. If we believed that psychosomatic symptoms were real and disabling and just as significant as a disease process, then none of these arguments would have to happen. What do you believe? I believe that the sickest patients, so I look after people with seizures. So many of those will have epilepsy. Epilepsy is a very serious brain disease. But let's say at different times, a quarter, a third of those would have seizures that are purely psychosomatically driven.

1:02:34And I would consider epilepsy is a life-threatening disease. it's very very serious but in many ways I would consider my patients with psychosomatic disorders to be sicker because it's less life-threatening however the symptoms are often worse so a person with epilepsy might have a seizure once a year once a week the person with psychosomatic seizure has 10 a day a person with epilepsy can take a tablet to get better a person with psychosomatic disorder has a real unraveling of of a complex brain mind problem to try and solve to get better Often people with psychosomatic disorders, their seizures are longer, they're more frequent, they're worse and they're harder to treat.

1:03:13I see that every day of my working life. So I believe that these are some of the most difficult disorders to live with. And I think that the narrative that long COVID cannot be psychosomatic comes from people who do not respect the severity of that brain mind problem.

1:03:30Amol Rajan:Just as a final thought, what's your sort of advice for individuals listening to this? And what's the kind of advice that as a society we should take away for individuals who you've provoked to think a little bit about what they do or don't want to know? So I never want to sort of say to someone, don't get that test or don't get that diagnosis. What I want is for people to get an understanding of both the negative, potential negative sides of a diagnosis and the positive sides so that they can enter into a conversation with their doctor that is knowledgeable on both sides. So it's not really about not being diagnosed.

1:04:06It's about understanding those downsides so that you can be prepared for them and make an informed choice about them. But more than anything, it's hard for an individual to solve this. I think the health service science doctors need to solve it, really.

1:04:20Amol Rajan:And at a social level, as a people, as a country, what do you want us to do differently? I want us to help people without labelling them. You know, we talk about suicidal people and, you know, we believe that we can help them by giving them a particular label. Well, why can't we recognize suffering and help suffering without having to give a brain disorder label to justify it? I don't understand why society can't figure that out. Well, maybe we'll get a little bit closer to it after listening to this podcast. Susanna Sullivan, Dr. Susanna Sullivan, it's a real pleasure and a privilege talking to you.

1:04:50Amol Rajan:Thank you so much. And thanks for sticking around to answer our listening questions as well. Thank you very much.

1:05:02Amol Rajan:What a very striking thing about Suzanne is that she's a doctor. She's very, very measured. She has a compassionate tone. And if you read her book or if you listen to her on this podcast or indeed other podcasts, I think you could say that what she's trying to do is not cause controversy, not fix political problems, but make patients, who she has spent many, many decades working with and trying to make better, just trying to make them think harder about some of their choices. And I feel genuinely, and it's the great privilege of what I do, that I learn an awful lot from that podcast and that conversation, particularly, for instance, the fact that when you think about something like prostate cancer screening, something I've thought about an awful lot, thought about it a lot after my friend and colleague, George Allagia, died of bowel cancer, saying that we all need to be screened earlier.

1:05:45Amol Rajan:I didn't know that lots and lots of people are treated for cancer when in fact they don't have it. And what she's really just asking us to do, I think, is to be conscious that a diagnosis, which is an appealing thing, a satisfying thing, a cathartic moment, it seems to offer clarity and certainty and a way forward. A diagnosis is a tradeoff. And at different times and different stages in your life, that knowledge or information that a diagnosis can give, A, that knowledge and information can be wrong. and B, it comes with trade-offs for how you live your life that we should just think a little bit more carefully about.

1:06:20Amol Rajan:It's worth saying there are lots and lots of controversial subjects in there, including about neurodiversity, and I hope you feel that I pushed back properly and fairly on all of that stuff and represented the views of those of you who got in touch with me to say that you had some qualms with Suzanne's thinking. She actually engages really meaningfully with all of those criticisms in our bonus Q &A episode.

Dr Suzanne O’Sullivan thinks that we are getting diagnosis wrong.

In this episode the neurologist and author of The Age of Diagnosis explains how advances in screening have led to certain diseases being over-detected and why she thinks giving a condition a label can sometimes do more harm than good.

And Amol asks about some of the criticism she’s faced since her book was published last year.
