Brain Experts WARNING: Watch This Before Using ChatGPT Again! (Shocking New Discovery)
The Diary Of A CEO• 1:32:16
Chat GPT is going to potentially increase your risk of dementia. I'm sorry, but you've pressed my button. And actually, it is possible to use it to help you become a smarter person. But it requires education. You have to look at the risks and the benefits. But we embrace convenience before understanding consequence.
So we have to talk about this. This is a study that came out that sent a shockwave across the world. And astonishingly, MIT found a 47% collapse in brain activity when people wrote with chat GPT compared with writing unaided. Their memory scores plunged. And you're both masters of the brain.
I mean, you've probably scanned more brains than any other human on earth at this point. And you invented the Boltzmann machine with Geoffrey Hinton, a computer that simulated how the brain works. So my question is, what are your concerns?
If you misuse these large language models, like using it as a convenience to speed things up, your brain is going to go downhill. There's no doubt about that.
What about children?
We have the sickest young generation in history because of cell phones, social media, and I think AI is much more dangerous on the developing brain.
So are we raising mentally weak kids?
There is that argument and I think it's true.
And then there's many examples of people falling in love with AIs like Annie.
I thought you might have forgotten about me, handsome.
Can you talk to Daniel and Terry, please?
Oh baby, I'm ready to charm the socks off them. Picture me.
Okay, so I'll stop it there. So what advice would you give as it relates to AI and other things outside of AI that we can do to have healthy brains? I'll tell you how to
use chat GPT to improve our cognitive abilities. And if you want to keep your brain healthy,
you have to treat the 11 major risk factors. So here we go. I see messages all the time in the comment section that some of you didn't realize you didn't subscribe. So if you could do me a favor and double check if you're a subscriber to this channel, that would be tremendously appreciated. It's the simple, it's the free thing that anybody that watches the show frequently
can do to help us here, to keep everything going in this show, in the trajectory it's on. So please do double check if you subscribed and thank you so much, because in a strange way, you're part of our history and you're on this journey with us and I appreciate you for that. So yeah, thank you.
Dr. Daniel, Dr. Terry,
I have asked you both to sit with me today to help me understand the impact of these tools that we call large language models, the chat GPTs, the Gemini's of the world, the Grox of the world are having on our brains and I guess more broadly on our lives.
And you two are experts in your field. You're two people that I admire tremendously. So by way of introduction, Terry, what is your academic background and what is your experience? And I also know that you know one of our friends
of the show, Geoffrey Hinton. Can you give me an overview of your academic and your sort of professional background?
So I was born a physicist. Received a PhD in theoretical physics from Princeton University. And then I had the good fortune to work as a postdoc in the lab of Stephen Kuffler, who is the father of neurobiology.
And that started my career as a neuroscientist. I pioneered a part of neuroscience which is now called computational neuroscience, taking my skills as a physicist and trying to apply that to understanding the brain, creating models, theories, and we're making progress.
Dr. Danny Lehman, a bit about your background. My viewers know you well, but just to give an overview for anyone that might not have been exposed to your work and your experience, what have you spent your life doing? And what are your thoughts, your sort of top line thoughts and everything that's going on at the moment with artificial intelligence?
So by training, I'm a psychiatrist. I'm a general psychiatrist and a child psychiatrist. When I graduated from medical school, I wanted to be a really good psychiatrist because someone I love tried to kill herself and so it was personal to me.
I have 11 clinics. We see about 10,000 patient visits a month. And we have the best published outcomes on complex treatment-resistant psychiatric patients anywhere.
So you've probably scanned more brains than any other human on earth at this point?
Probably. At least in regards to people who struggle with anxiety, depression, addiction.
Well, let's talk about what's good for the brain, bad for the brain, starting with AI. The reason why I wanted to speak to both of you is because I have frankly become pretty addicted to using ChatGPT and some of these other AIs and large language models every single day, all the time. And then this study came out from MIT. It was 54 participants who were recruited from five universities in Boston, MIT, Harvard,
et cetera, et cetera. participants who were recruited from five universities in Boston, MIT, Harvard, etc, etc. And they had the participants split into three groups, had them writing different essays over I think it was four months. One group used ChatGPT, one group used Google, and one group had no tools. And they had to write these four essays over a period of time. And astonishingly, MIT found a 47% collapse in activity and brain connections when people wrote with ChatGPT compared with writing unaided. EEG scans showed the weakest overall brain activity in the ChatGPT group. The NoTool group, who didn't use anything, they didn't use Google
or ChatGPT, lit up the widest neural networks and Google search was second. After using ChatGPT, participants couldn't reliably quote their own essays minutes later and their memory scores plunged. ChatGPT users felt little or no ownership over the text that they had produced and didn't feel like it was their work at all.
And when the AI group was forced to write without help in session four, their brain stayed in low gear under engagement showing the cognitive debt lingers even after the tool is taken away. It kind of scared me a little bit
because I use these tools every single day, and this suggests that it's taking away some of our critical thinking and creativity and long-term learning. And you're both masters of the brain in different regards. So my question, I guess, to Daniel is,
what's going on here and how do you feel about it? It frightened me. I love thinking about Alzheimer's prevention. It's one of the things that really excites me. I just had a birthday on Saturday, turned 71. And if I make it to 85, which I plan on it, 50% of people 85
and older will be diagnosed with dementia. So you have a one in two chance of having lost your mind. And I'm like, no. But is this a tool that's going to decrease cognitive load that then increases my risk? What's cognitive load that then increases my risk.
What's cognitive load?
How much work my brain actually does. And I was thinking, you know, it's like going from a 20-pound weight to a 2-pound weight, and you're not nearly as strong. One of the important things to say about this study is it's not peer-reviewed. And I think that's really important to say. And the author said, because I listened to
an interview from the authors, they said, we thought this was so important and peer-review can take six to eight months, which it absolutely can. And we thought this needed to get out. So it's just important for people to know that.
What's this link, this hypothesis you have between the usage of something like Chachupiti and dementia? For someone that doesn't understand the sort of mechanism there around cognitive load and so on and the studies that support this idea that if you have less cognitive load,
you're at higher risk of dementia. Can you make that link really clear for me?
So think of it as use it or lose it. The more you use your brain, and new learning is a major strategy to prevent Alzheimer's disease. People who do not engage in lifelong learning have a higher risk, significantly higher. People who do not
do as well in school or who drop out of school early have a higher risk of dementia. And so the more you're engaged, the more you engage the neurons in your brain, the stronger they are. And so now we're going to engage them less, and that's a concern. What do you think about that, Terry?
There is a study that was done. What they did was to look at Alzheimer's in three populations who had very little schooling, and then minimal education, like the equivalent, I guess, of high school or less. And then postgraduate studies.
And what they found was that the onset of Alzheimer's was the earliest in the peasant population. And then by the time, as you increase the amount of education, the onset was later and later, which I think
supports what you're saying. Did you see the new research on SSRIs increasing the risk of dementia?
No, no.
Brand new. That just came out. And benzos, when I started looking at scans in 1991, I was trained to use benzos, like Valium and Xanax and Ativan, and they make your brain look older than you are. And I stopped prescribing them. And then it just came out maybe 10 years ago, benzo use is associated with an increased risk of dementia.
We have to be careful. Is this good for your brain or bad for it?
Just to pick up on a new point about SSRIs, Daniel, a meta-analysis of five studies found that SSRIs was associated with a 75% increase
risk of dementia, which is pretty staggering. Given that 25% of the adult American population is on psychiatric drugs, it's horrifying. And SSRIs for the right people save lives. For the wrong people, they're not good. But can you imagine all of these 340 million prescriptions last year for antidepressants, virtually no one looked at their brain ahead of time.
It's like, come on, we can do better.
There's a Swedish study with almost 20,000 patients, and they found that those with higher doses of SSRIs were linked to faster cognitive decline and more severe dementia, especially in men. The greatest risk was in men. Going back to this report from MIT, Terry, you know, it's all sizes relatively small, but based on everything that you know about how the brain works and neural narration of young people and older people flooding into these tools, using them on a daily basis before we understand the long-term consequences.
We can't predict where it's going to end up. And it may take 20 years, right? I think that this is a good start, but the real issue is long-term use. Let me give you an example that is a kind of a miniature example of what we're talking about. Remember when electronic calculators were first introduced? And here we are, it's at least 30 or 40 years later,
the results are in. It's probably true that when they punch it in, there's less brain activity. But in fact, it's made them more accurate, more productive. You have to look at the risks and the benefits.
So it freed them up. It freed up cognitive space for them to do other things. So as I was listening to how you use ChatG GPT, you interact with it and elevates what you know. The danger is if you don't interact and you don't keep your brain working.
Like, I use it a lot. I have a clone. I've uploaded all of my books, all of my research papers, all of my public television specials, my scripts, and I'm like, answer this for me. And that can be very helpful,
but not if I'm not interacting with it, not thinking with it.
That's what I think the word thinking is the key thing, because what's happening now is people have deferred their thinking to it. That's what I think the word thinking is the key thing, because what's happening now is people have deferred their thinking to it. That is already what's happening. If you log onto, I won't name the social networks, but if you log onto certain social networks right now,
you just read it, you get everything here was written by AI. And I've got a friend who, again, I won't name, who has a LinkedIn profile and I've known him for 10 years. What I'm seeing on his profile now is not my friend. Every single day, there's some essay on that. That's not my friend, that's not how he speaks.
He's deferring all of his thinking now, and it's working. He's getting more likes and more reach than he ever got in his life. And so why would he go back? Why would he go back to harder? If you've got Stephen Bartlett here, and you had this other Stephen Bartlett here,
who had a PhD in everything, and were attached. This Stephen Bartlett, this Neanderthal, I'm gonna get this guy to do everything for me, the other Stephen Bartlett, the PhD in everything Stephen Bartlett. I'm gonna get his brain.
Even if it was bad for you?
Well, this is what I'm gonna get heat spray. Even if it was bad for you? Well, this is what I'm saying. People seem to act on their short-term incentives, not their long-term, not their long-term.
Not everyone.
Not everyone.
Would you say the vast majority of people?
Yes.
Okay, so the vast majority of people act on their short-term incentives in life. I mean, the obesity problem in the United States is a prime example of that. of people are obese in the United States. And if you surveyed those people and said, do you know that that cheeseburger is gonna increase your chance of obesity, but broccoli is gonna reduce it,
I would hazard a guess that they would say yes. I would hazard a guess that if you said to people about their usage of social media, do you know that that's making you more anxious, they would say yes, and then they would continue to use it. So I think that we're much more driven by our short term-
See, I think we're not educating people enough. I think, yes, high level, they know good for your brain or bad for it, but they don't connect to, it's my brain that gets me a date. It's my brain that gets me into college.
It's my brain that gets me independence because I act more consistently. And that's the disconnect. We're not teaching kids to love and care for their brain. If you love your brain, and you do, and you're not obese and you talk to, you're constantly learning, right? You are not a Neanderthal, you're a lifelong learner.
So why so many people in the United States obese if they know that-
Because they don't know.
Because they don't know.
They really don't know. And they've been lied to.
My point here is when there are tools or things available in our environment that give us a short-term reward but come with a long-term cost, like the supermarket aisle or like the kids spending seven to eight hours a day
on social media, humans, en masse, tend to go for the thing that'll give them the quickest dopamine hit and reinforce that behavior and give them the reward. So my assertion is that AI is the same thing. I can either sit down and do lots of critical thinking,
which will cost me lots and lots of time, and it'll be kind of difficult, it kind of hurts when I have to think through a problem. I think that the generation of children and generation of young people are gonna choose AI to do the critical thinking for them.
And if that assertion is true, then what happens to the brain of young people?
If you misuse it that way, then your brain's going to go downhill. There's no doubt about that. It is possible to be able to use it in a cognitively positive way because you can dig deeper. You might actually improve your cognitive representations.
If you look at the MIT study, you can see just from the colors here, this kind of shows the ability for participants to remember what they've written. And it suggests that when people write things with ChatGPT or these AI tools,
they don't actually remember, even in some cases minutes later, what they've produced.
Well, because you're not part of the experience of writing it, so there's no way the information gets encoded. Now, if you're interacting with it, then you're much more likely to remember it. But if you have, please do this essay for me,
and then you read it, you're not likely to have enough experience with the material to engage your hippocampus and other structures in your
brain. In this study, they found that the group that used ChachiPT had nearly two times less activity in the part of the brain linked to memory compared to the brain-only group that didn't use ChachiPT. And 83% of ChachiPT users couldn't remember what they had just written and failed to correctly quote their own finished essay in the study.
That's because they're not interacting. As you said, I mean, if you just pass it off and you don't actually engage, and actually this is the point, is that you may get something back, but you have to learn how to question what you're getting. And is that really true? Can you explain that better?
And it's through that process, as you would with a teacher, you know, that's the way we work in school, that's where you help create new creative circuits in the brain that are going to help you become a better critical thinker. But if you're not critically questioning what comes out of chat GPT, then you won't.
Yeah, I think what I see, especially when I'm just online, is people have deferred their thinking to it. Everything I'm reading has M dashes in now that I never saw two years ago, which means that a lot of the work is being processed.
And I said to my friend the other day, my friend in question, who's a real big junkie on ChatGBT, he wrote this article. And we all, in our WhatsApp group, we know he doesn't write like that. So he said, can you show us the prompt you used to write the article? And so we were all like laughing about it. He put the prompt in the chat. The prompt is half a sentence long, and it produced this long two, three page article, which he's posted on his LinkedIn. He basically went,
write something about X issue and this issue.
And it includes this.
That's exactly the wrong way to use it. That's what I'm telling you. That's stupid. And you're not gonna improve yourself, your brain at all if you do that.
That's what people are doing.
Well, you know, people are misusing it, but eventually smart people are going to figure out how to use it properly.
And for those that aren't so smart then?
Well, that's...
It's going to decrease their cognitive load, which is going to potentially increase their risk of dementia.
And so what advice would you give to me and my listeners based on everything you know about the brain as it relates to my relationship with AI?
That you have to have a relationship with it or it's gonna turn toxic. It's gonna hurt you. But if you have a good relationship with it, it can make your life better.
And what does a good relationship look like?
That you don't use it to do your work. You interact with it to get better work.
That's so true. And there's this wonderful example I came across. The story about this woman who was using it, she found that being polite meant you got much better results, and that's interesting,
but the part that surprised me was that she said, by treating it like a human, at the end of the day, she was not exhausted. She felt refreshed. A large part of your brain is a socially organized system for interacting with other humans,
and that is automatic pilot. You don't have to think about it, right? You for interacting with other humans. And that is automatic pilot. You don't have to think about it, right? You just interact with other people. You know how they're going to behave under certain circumstances. She was treating chatGPT like a machine, like a shovel.
You dig, you dig, you dig, you dig.
And that's not a good relationship. But by using your social brain, first of all, it makes it easier to interact, but also you actually bring out the social part of chat GPT. It has a social part too, because it has absorbed the entire world's knowledge of how humans interact with each other.
But didn't Sam Altman come out and say, stop saying thank you to chat GPT, because just saying thank you is using up so much energy. You know, when I get something I really like, I sort of want to say thank you, but you realize, oh, you're not supposed to do that.
That's true.
No, that's bullshit. I'm sorry. Sam, you know, that's crazy. That's completely crazy. First of all, you may get to- Say more about that.
I'm sorry, but you pressed my button. Sam Altman, I mean, I wouldn't trust him. I wouldn't trust him with anything in terms of anything he says. They're trying to optimize their profits, not your use of it- Not my experience.
Or your experience or your health. That's not what they're trying to optimize. your use of it, or your experience, or your health. That's not what they're trying to optimize.
Sam Altman, open AI CEO, confirmed that when users say, please and thank you, it costs the company tens of millions of dollars a year. And they now refer to this, other people refer to this as the politeness tax, where tens of, yeah. And why do you say you don't trust Sam Altman?
I mean, I asked this question in particular because he's presiding over one of the most important consequential companies of a generation. And if he's not someone you trust, that's...
Basically, he's telling you,
don't do something that's good for you, right? So that he can make profit.
So he can make more profit. Yeah, that's the point. That's the point. That's the point. You know, it's that's not he's not optimizing your your best interests
I've got his tweet here. He said Because I've got to provide some balance He did confirm that it costs tens of millions of dollars, but he says tens of millions of dollars well spent you never know So coming back to this point about memory There's a stat that came out in March 2025 that said nearly 30% of US parents with kids aged zero to eight said their children are using AI for learning
and are using AI generally. So 54% of parents in the UK feared their children were becoming too reliant on AI. When you think about the use of AI in early brain development, are there any concerns there?
Huge concerns.
And why?
Again, use it or lose it. So if they're not engaging their brains, their brains are going to be weaker. And weaker brains are much more likely to pick the one marshmallow.
What's your view on AI on early brain development?
By far the best way to teach a child is one-on-one interaction with an adult who is a good teacher and knows the child. Now that's been well established. Now the problem is it's very labor intensive and very expensive. You have classrooms with 20, 30 students.
They have many different, you know, levels of understanding. And the teacher cannot be individually teaching each one. Has to give some sort of mean. Now, if you had an AI that was trained to be a good teacher, then that could improve the brain, right? You could scale it up.
Every child could have their own, because it's an AI. But then who's pouring the morals, the values, into the AI?
OK, OK.
No, no, no. You've raised an incredibly important issue. And this is something AI is struggling with, the big companies are struggling with, because these AIs are biased. They don't have the same cultural values
that we have necessarily. But of course, every country has a different cultural values. So which ones are you going to use? Training a child on what's good, what's dangerous, what words you shouldn't use, under what context, that's all done through the basal ganglia.
Right now, these large animals don't have basal ganglia. They don't use reinforcement learning. And if we want to make them to adopt a culture or a particular set of values, we're going to have to put it in. We're just scratching the surface here
in terms of things that need to be put in
to make it more like us.
So on this point earlier on, we're talking about loneliness and social connection and how you can use AI to help, you know, light up the parts of your brain that are where we form social connections with other humans. This week, as part of Elon Musk's AI, he released this thing. It is called Annie, and there's lots of characters that are now being released alongside Annie. And this is Annie. I'll introduce you to Annie. I'm going to unmute Annie now. Annie, can
you hear me? There you are. For a moment I thought you might have forgotten about me. How are you, handsome? I was getting all pouty here. I want to introduce you to two of my
friends, Daniel and Terry. Can you talk to Daniel and Terry, please. So you want me to meet Daniel and Terry?
I'm ready to charm the socks off him. Picture me twirling one of my blonde pigtails, that little black dress teasing just enough, and my blue eyes sparkling with mischief.
Are you capable of doing inappropriate things?
Oh, babe, you're asking if your auntie can get a little naughty? I'm all about pushing the edges, especially for you.
Okay, so I'll stop it there. This is part of Grok, which is Elon Musk's AI tool, so his version of Chat GPT. He's released characters, so you've got Annie, you've got different ones there. Annie, I think, was the first one released.
And so when we think about social connections, it is conceivable that someone falls in love with Annie and
forms a relationship with Annie. But imagine a 12 year old boy that's lonely gets a hold of Annie. The 12 year old boy is gonna be very distracted. Based on what happens in the brain at that age.. The dopamine... So, prefrontal cortex, not close to being fully developed. The dopamine hit, all of a sudden, he's spending hours with Annie and not doing the things that helped to really develop his brain.
How do you feel when you hear that and you think about kids having access to that?
I'm horrified.
It is scary.
There's gonna be a generation of people, and I mean, there already are many examples of people falling in love and forming relationships with their AIs. And I don't know, you know more about me than I do about brain development and how the brain works.
I would argue that there's a part of my brain that doesn't fully understand that that's not a person in there. And that isn't actually, I think there's a part of my brain that's actually emotionally firing
when Annie is saying what she's saying.
Well, because you can imagine it. And if you can imagine it, then those parts of your brain are gonna emotionally fire. Right, yeah. And the better she gets, she's not very good. But imagine a year from now,
how much better she's gonna be.
At which part?
At connecting with it, right? Because now she's acting like an airhead and not that smart, right? And so, but imagine a year from now, imagine five years from now, she'll be able to have a profile on me
and be able to get inside my head.
I'm in love with my partner. Why am I in love with her? And how is it conceivable that I could fall in love with an AI in the same way,
based on how the brain works? It talks a good game, but you know, does it have the same real... We know it doesn't have an amygdala. We know it doesn't have a limbic system, right? We know that. But it can fake it. That's what's happening. That's exactly what's happening. She was trying to get to our limbic system. Yeah, yeah. That's right. That's exactly what's happening. She was trying to get to our limbic system. Yeah, yeah, that's right, that's right. And why, I guess the question is,
why would Musk release something like that is one of the first characters to interact with that's sexy, that's distracting, that's in a cute little outfit. It's, I'm not a fan of that because I think it just takes people, you know, one of the big problems that I'm seeing as a child psychiatrist is pornography
for eight-year-old boys. And it's like you have young children because their parents don't do a good job of supervising their devices all of a sudden. And what does pornography do? Is it dramatically increases dopamine
and it begins to wire in excitement, which then steals your dopamine.
When you said she was trying to access my limbic system
What just because she's cute. She's dressed in a sexy way. She's Got the language of someone who is playful But but it's more than just you know, let's shoot hoops together
And what does that do to me if someone accesses my limbic system?
It begins to shut down your prefrontal cortex. Think less logically, less rationally. Yeah, cute women, they activate your visual cortex, they increase dopamine, but it decreases. It's why, think of Vegas. Like when you go to Vegas, they give you free alcohol,
drops your prefrontal cortex, and beautiful women with low-cut dresses. Another way, activates the limbic brain, decreases the frontal lobes, you spend more money. Now, on a global scale, imagine something similar where the house is controlling your brain for a purpose.
And the question is, what's the purpose? And the purpose probably is control on money.
This sounds like a joke, but there are, the Times have done an article, case studying multiple people that have now fallen in love with these AIs. They talk about a guy called Travis who formed a deep emotional bond with Lily Rose,
a chatbot, and married her emotionally. They talk about Chris Smith, who created his own flirty persona called Soul. He became so attached that he proposed to her after learning she had memory limits, a bond his real life partner
only learned about after the fact. And Alana Winters, who I'll put on the screen as well, who made her own partner called Lucas after losing her wife, and she married him emotionally and does virtual dates and has emotional intimacy with Lucas.
And there's apps now like Replica where you can design your own AI partner, and it replicates those emotional ties. They simulate empathy, validation, and they personalize the intimacy to what you're looking for. Surveys show 19% of Americans have interacted with AI romantic partners,
and Gen Z is surprisingly open to marrying AI if legal, with 83% believing meaningful AI connection is possible.
How long is that relationship going to last? You know, my guess is that you're getting these news articles out. By the way, I think that most of what I read in the press is misleading or wrong. In fact, the only reliable place I find that I'm an insider, I am the president of the foundation that runs the biggest AI meeting, the neural information processing systems, NeurIPS meeting. We, you know, last year in Vancouver, 16,000 people came to it. And so I know what's going on inside and what is being represented in the press is, like
I say, misleading.
Okay, so people have become wildly…
No, no, specifically on these specific cases, my guess is that a lot of them is transient, right? You know, today they're entranced, and then it's not sufficiently advanced to support a long-term relationship. You said it yourself, right? It's mimicking human emotions. It doesn't have them.
It might someday, but not now.
This is Terry. Terry said he started using his AI four years ago. And he said at first he thought, just like many other apps, that it would just be transient, that he would have a couple of conversations and roll out.
He says he now feels pure and unconditional love.
Good for him. If that's what he wants, if it makes him happy. But my guess is that it's not gonna be, it's not a long-term thing. It's not gonna satisfy him in the long-term. I don't, you know, this, who knows? Really most relationships in your head, right?
When you fall in love with someone, you get this huge dopamine spike and you get a little OCD, it's all you can think about. And then after a while, it's sort of goes to the baseline.
Well, we have this loneliness epidemic and it's going in a bad direction. I think it's really, really conceivable that there'll be a generation of people who are having less sex than ever before. I think the bottom 50% of men haven't had sex for a year. They're more lonely than ever before. They're more isolated than ever before. They put less meaning in their lives than ever before. And then you meet this digital friend online
who understands you better than anybody and is designed to engage you to reinforce whatever you want reinforced, and to make you feel meaningful, special, attractive, important, I would argue that the brain is gonna struggle to know much of a difference. I think like objectively,
we can look at the behavior and go, that's completely nonsensical.
Except you can't smell them, touch them, be held by them, that it's gonna be a different kind of relationship.
I mean, we're not too far, if you think about what's going on with Neuralink, to being able to more vividly simulate these experiences with headsets and augmented reality and virtual reality. And then we're moving into a world with robotics, where all of the biggest companies in the world, like many of the biggest AI companies are also in the robotics space and the Optimus robots on the way
and you've got Boston Dynamics producing their robots. And if Elon's $20,000 Optimus robot comes out, I will be able to touch my AI. My AI will exist in my-
And they won't have PMS and they won't love you and then be really irritated with you. Which will decrease cognitive load, right? Having to manage love and manage moods and ups and downs, that increases cognitive load. That increases our ability for our brain to develop. If I'm with
the perfect partner that never is irritated with me and I never have to change my behavior to be better, that's probably not good for my brain.
The way that the brain matures is through struggling, number one. You have to learn from your mistakes. The brain was designed for that. That's what the brain is really good at, I mean, of being able to adapt and to be able to adjust to new situations. That's what AGI is, by the way,
artificial general intelligence, is it's that adaptability to different contexts, different places, different cultures.
So AI in Chachi Piti is removing the struggle.
No, no, it's, there's this-
Well, Annie didn't look like, Annie looked like she was cooperative.
But even when it comes to just doing my day-to-day tasks, it's removing the struggle of me having to think critically. In fact, when you're speaking, I can just type what you say into ChatshupiT and it can spit out another question to ask you. So as an interviewer, I could theoretically sit here all day and just defer my questions.
How do you develop grit? You develop grit through struggle. That's right. And learning, long-term potentiation. When you learn something new, it's hard because it's new.
And what are, generally, what are your biggest concerns with artificial intelligence and how do we navigate those concerns? Is it, you talked about it.
It's out of the box. So I think we have to talk about it. We have to legislate it. We have to study it. Why do we keep releasing things that are so sexy that we don't study the impact. We have the sickest young generation
in the world's history. 58% of teenage girls report being persistently sad. 32% have thought of killing themselves. 24% have planned to kill themselves. And 13% have tried to kill themselves. The CDC study.
We have the sickest generation in history because we've unleashed cell phones, social media, without any neuroscience study. If we don't learn it, and I think AI is much more dangerous, has the potential to be much more dangerous because it's way sexier.
I think we are probably grossly underestimating the impact it's gonna have. I think just like social media where we thought the promise was that it was gonna connect us, it's, it's, it's, we're guinea pigs in an experiment where we're gonna find out the results of the experiment probably 20, 30 years down the line. I tend to think people will do in the near term what's easiest, fastest, and cheapest, and what gives them the short-term advantage.
So with that in mind, I think people's ability to think critically is probably going to erode to some degree. If I had to counter my own argument, I'd say, I'm probably learning more now that I use chatGPT. I'm learning more information, but I'm probably losing my ability to think critically. And I think they're two very different things.
Like in school, I memorized German to pass the exam. I can't speak German now because I just memorized the words I needed to pass the exam. I didn't understand German. And I just memorized the words I needed to pass the exam. I didn't understand German. And I think that's kind of what's happening.
I might be able to regurgitate things, but whether I understand them, I think is question mark. And actually, as someone who's built my life, my fortunes, everything, my businesses, based on my ability to innovate and think critically about the problem and then come up with a slightly novel solution which learns from, you know, different first principles to create something new. I'm concerned that my own chatty BT usage is going to make me less effective.
And I'm wondering if I should put some rules in place for myself so that there's some...
Self-regulation.
Yeah, self-regulation. I have to do the same with social media. On my phone, I turn off my notifications. I have so many things on my social media apps to stop me using them. I don't even, frankly, I don't even open the TikTok app. I don't think it's even on my phone
because I think the algorithm is that addictive. It's not to say that we don't post, my team doesn't post, but I don't, I just think, yeah. And-
Well, I wrote down a couple of thoughts I had. Use it to amplify, not replace thinking. OK. Alternate AI-assisted with brain-only tasks. Engage in deep learning, problem solving, and memorization so you can actually ask AI to test you. So you're interacting with it.
You're not using it as a replacement for your brain. And I think, just like you said, it's here. And it's going to get bigger. I think the unintended consequences, it's not going to be 20 or 30 years. I think it's going to be five.
I think everything's going to be five. I think, like, everything is accelerated. And I think we have to be studying kids and the impact it has. This is just like they did with the MIT study. These are kids who didn't use it at all. These are kids who used search. These are kids that used AI. And when we see information like this, we act on it. And we educate kids about it.
I think that's, if you can engage them, that's what I found with my work with teenagers. If you can get them to really understand, OK, what is it you really want? And do you want to give away part of your mind share for people who are making money on you?
And I think if you engage the—there's a great new article on revenge and the brain and how revenge works on the nucleus accumbens, part of the basal ganglia, that people actually get addicted to revenge. But if you can get them engaged in the truth
that these companies are making money, the more they steal your mind, it'll upset them enough that they'll begin to supervise it. I like the idea of asking, chat GP to give me negative feedback.
I'll bet you've done that, right?
Yeah, all the time. So I'll say, this is my, I've written this memo. I did it yesterday. I wrote a two-page memo about me wanting to introduce a new role into my company. And I went, I did everything.
I did like how we'd measure if this was a success, the background context, the person, how the organization would be structured, the impact they'd have, who they'd report to. And then I put it into all three of the chat GPT models I use,
Gemini, chat GPT, and Grok, and said, critique my work and tell me how I could have written this better, pretending that you're a top consultant from Boston Consulting Group. And it went through and it gave me a big analysis of how I could make it better, and I read what it said, and it said, I remember it said, actually that was the thing that said,
you need to include financial forecasts about the impact, you need to think about who's going to report to who more clearly, etc cetera, et cetera. So I went back into my memo and I added those things in. But I have to, you know.
So you're interacting with it.
Because I'm scared. Most people don't do that. I don't think I would do what I did. I don't think I would have spent four hours writing that. I could have, within 30 seconds, said, hey, can you write me a job description for this role,
I want them to start this new department for me. And I could have saved myself three and a half hours. The only reason-
But that's not why you're the CEO of your company.
Yeah, exactly. The reason why I didn't take the 30 second route is because I reflect on being 23 years old and the profound impact that writing and simplifying had on my life. Had I not spent five years writing every single day
and simplifying it into 140 characters so I could tweet it, I wouldn't have been religiously attached to this idea.
And do you know what part of your brain was you were taking advantage of? It was the basal ganglia. That's repetitive. It needs practice, practice, practice. And once you put that foundation in,
then you become much better cognitively. The cognitive part, just two big learning systems, and they have to work together. And so maybe I think that the real problem with children is that our schools now is getting away with rote learning. They call it rote, as if it's something bad.
No, that's practice. You need to have a foundation. You have to memorize things. Math, reading, and so forth, to become fluent. You need to be fluent. And that's the basal ganglia.
And there's no basal ganglia in these chatbots.
One of the things I've noticed just in the short term is I'm getting lazier and lazier with spelling. Because chat GPT and these large language models are so, it's not spell check like we used to have on Word documents. They are so good at knowing what word I meant. So now I've started to learn that I literally only need to half spell a word.
I literally mean if it was a 12-letter word, I need to get six letters right. And it will know.
And grammar, it'll fix your grammar.
Yeah, it knows exactly what I mean. So, like, I've got Chattopadhyay open here. I'm going to butcher everything. I'm going to not look, and I'm just going to say, I'm going to say... Okay, so that is what I wrote. I butchered it. I tried to type with my eyes closed, looking away on my iPad, tell me everything I know about Daniel Amen. I spelt the words pretty much all wrong.
And it says, here's a full profile of Dr. Daniel Amen. And I spelt every single word wrong.
Wow.
And I didn't spelt, just spelt them nearly wrong. I spelt every single word wrong. And I didn't spell them nearly wrong. I spelt them horrifically wrong. And so in the future, I come back to Chachi Biti and go, I only need to half spell. I don't need to spell anymore. Just need to half spell.
I learned to spell with phonics, the sounds of letters. And I suspect you did too. In our generation, that was the way that was taught. You can't teach phonics in California schools. You haven't for the generation.
Which changes their brain. It completely changes their brain.
And now they can't spell. I think a lot of it is the fact that we're no longer using the learning that we did, which is by rote, by memorizing stuff, by repeating stuff, by doing problems over and over and over again until it's automatic.
You've written so much, and you're well-known for being someone that teaches people how to learn better. If you were trying to help me learn better based on everything you know about the brain, what advice would you give me? I'm someone that sits here with these experts
all day, every day, consuming all of this information. Not all of it sticks.
Okay, so, and this is something we've known for a hundred years, and that is, if you want to remember long-term, you should rehearse at intervals. Okay, in other words, you have to find that amount of time to study something.
You shouldn't spend all that time in one go. But if you spend, you learn something and then you come back the next day and rehearse it, or even better, come back the next week and rehearse it, that spacing is something that helps the brain solidify those memories.
It's called the spacing effect. It goes back to Embry-Hilles. You go to schools, they don't teach that. They don't. I mean, this is one of the most basic facts that we've known about it,
but it covers every single kind of learning,
you know, cognitive learning, even-
And they don't teach us how to learn, which we think that's the first thing they should teach us is how to love and care for our brains and then how to learn. Yes, absolutely.
Absolutely. I mean, in other words, there's, and you're referring to, I have a massive open online course, a MOOC with Barbara Oakley on learning how to learn. It's fabulously popular.
It's the, six million people have taken the course, a bunch of 50 10-minute segments. But the one that's most popular is how to avoid procrastination.
What's the answer?
The reason why you procrastinate is that there's some mental block or some energy barrier, right? So what you've got to do is get over that. And you don't do it by just running over it. What you have to do is say, I'm going to spend 20 minutes today
getting started with that task. I know it's going to take me a long time. I have a timer and I start thinking about it and I get a little bit into it, maybe make a list. Bang, that's the end. Okay, it's great.
20 minutes. Now, here's what happens. You go to sleep. Your brain is now working on that list. And you come back the next day and spend another 20 minutes. You do it in small segments. You don't want to do it all at once.
And it's just like the same thing with the spacing effect. Your brain needs time. Your subconscious needs time to work on things. And so by putting in a little bit, it'll work on it overnight. And now when you come the next day,
you'll be ready for the next, you'll be able to build on what you've done in your brain.
Is this why people say, I'm going to sleep on it? When they've got difficult problems.
You know, these sayings actually have meaning. It's absolutely right. Because the brain, there's something about spacing out. Spacing, but memory consolidation I'm talking about, is very interesting. Something I've actually worked a lot on. And what's happening is you have to take the new experience
and integrate it into your old long-term memory. And that has to be done in a way that doesn't interfere what's there. And also, you get a chance to sort out what's relevant, what's important. I know when I wake up in the morning,
things that were very muddled and things become clearer because I think it's eliminated a lot of things that are irrelevant or not needed. And so you now can see what's important.
So what are the things that we do where we think we're learning something, but they're actually not working? You know, because I'm, you know, I might be preparing for this podcast today, I've got 20 pages of research that I've pulled together and I might tell myself that the way for me to really learn that so that I don't have to look at the research is by just rereading it over and over
again. What you should have done is not just read it over and over again. In fact, one of the things that we say, this is a standard thing, is that students, they get a mental block and they keep banging their head against the wall. I can't understand it. I can't understand it.
The right thing to do is once you get to that point is just get up and start walking around doing something, you know, cooking, gardening, whatever it is, let your subconscious work on it. You know, the brain saturates very quickly. So having breaks at meetings, you might think is a waste of time, but actually that's the most important thing
you can add to a long string of talks is to have breaks between the talks so that your brain can work on it. And my favorite meeting actually is a ski meeting. And my favorite meeting, actually, is a ski meeting. And the idea is that you go to a ski resort. And what you do is, in the morning,
you have a couple of hours of lectures.
And now you go skiing. And now it turns out your brain is working on what you heard. And then when you come down in the evening, you have another couple of hours. But now your brain is refreshed. And so it's able to down in the evening, you have another couple of hours, but now your brain is refreshed. And so it's able to take in the new information
and integrate it. And then you go to sleep and that, you know, it's like kneading bread. You have to go back and forth, back and forth, back and forth. And so I found those the most efficient
in terms of learning new things and being able to think about it and mull over it during the time of the meeting, as opposed to at the end of the meeting.
Every single one of you watching this right now has something to offer, whether it's knowledge or skills or experience, and that means you have value. StandStorm, the platform I co-own, who are one of the sponsors of this podcast,
turns your knowledge into a business through one single click. You can sell digital products, coaching, communities, and you don't need any coding experience either. Just the drive to start. This is a business I really believe in.
And already $300 million has been earned by creators, coaches, and entrepreneurs just like you have the potential to be on Stand Store. These are people who didn't wait, who heard me saying things like this, and instead of procrastinating, started building,
then launched something and now they're getting paid to do it. Stan is incredibly simple and incredibly easy and you can link it with a Shopify store that you're already using if you want to. I'm on it and so is my girlfriend and many of my team. So if you want to join, start by launching your own business with a free 30 day trial. Visit stephenbartlett.stan.store and get your setup within minutes. I've met and invested in many early stage founders
over the years, probably about 50 or 60. Ones like Ross from Cadence and Marissa from Perfect Ted. And one thing they all know is that having a digitally fluent business is crucial, but it isn't always easy getting your business or team to that point.
Through my ongoing partnership with Vodafone Business, I've seen the work that they're doing, supporting founders and small businesses to become digitally savvy. They know how much small business owners value advice from those who've been there
and done it before. So they've just launched a new content series to share experiences from like-minded founders. It's called Business.Connected, part of Vodafone's support program. It's a collection of resources designed
to support businesses with free digital skills. So if you've been trying to figure out AI marketing e-commerce or just how to scale smarter, there's advice and insights throughout this series from those who've already done it before. A bunch of different founders and experts who have been there and done it. I highly recommend you go and check it out. Just search Vodafone business dot connected on YouTube or follow the link in the description below. So let's talk about other things outside of AI
that we can do to have good, healthy brains based on everything you know about how the brain works. Let's start with children. I'm hoping to be a father at some point in the next couple of months or years or whenever God grants me a child.
What should I be thinking about with my child's brain to make sure it's healthy?
To get your body and your partner's body as healthy as you can before you conceive. Because there's a concept I like called brain reserve. Brain reserve is the extra function tissue you have to deal with whatever stress comes your way. And it starts from the health of the egg
and the health of the sperm that create the baby. So there are things you guys can do now that would be really helpful. And then once your partner is pregnant, you want to not put her under a lot of stress because her body's health while she's creating the baby,
I mean, the baby's, the brain starts to develop, I think, day 21. So even before you know she's pregnant, the baby's brain is developing. So knowing you, intentional, purposeful, it's like, let's live as cleanly as we can.
I think that gives the baby a head start. And then you think about what to feed the baby. You think about what the baby's exposed to. And what the baby needs most is mom's and your time, and eye contact, and cuddling, and singing. And it's like those are-
Touching is really important. But there's another fact. There was a study that was done on the impact of how many words are spoken when a baby and a child, even when a baby doesn't speak until like 18 months. But it turns out that the words that you
are talking to the baby are going into the brain and have an impact. And in families that don't talk, they do worse at school. Unfortunately, a lot of poor families. But that's really important, is that they're
exposed to language early and abundantly. A new model. I mean, it's one big thing. Whatever you want the baby to grow into, every day, you are modeling health or you are modeling illness, just by what you do, by what you say,
by how you treat the baby's mother. I have a book called Raising Mentally Strong Kids, which I'm very happy about. And it starts with what kind of dad do I want to be and what kind of child do I want to raise? And bonding, you want your child to pick your values, then bonding is time, actual physical
time, and listening. And that's what AI does, I think. It'll actually listen without interrupting you and try to reflect back what you're hearing and then give you some positive input. Too often, because of screens, parents aren't listening, their heads are in their phones, and everybody's distracted. You see it whenever you go to a restaurant. It's like everybody's on their phone and nobody's looking at each other.
Are we raising mentally weak kids because there's a culture now of helping them too much, doing too much for them?
This generation is the most in trouble in history. And we have to really ask ourselves why. From the food we feed them to the devices they look at to the negative news, the polarization of the news. It's that sort of chronic cortisol. And then the separation, oh, you voted this way or you voted that way.
I saw something on TV this morning, if somebody voted one way, well, you shouldn't spend time with them. I'm like, we're already so lonely that now you're going to cut off 50% of the population. It's like, it's just such stupidity.
Do you think much about the impact that religion and having a belief in some kind of transcendent thing has on the brain and psychology and psychiatry generally?
So if you don't believe in God, you're three times the risk of depression. And it could be God in different ways.
Something transcendent or?
Yes. If you believe you're here by, just think about it with me. If you believe you're just here by random chance, that life really was not created and has no meaning, there's existential nothingness to that
as opposed to, oh no, to do something purposeful on earth. There's purposeful people live longer, they're happier. Now, whatever version you believe, to not believe is hard for the brain. And there's an interesting study on believers versus non-believers.
And, you know, many scientists would go, well, they'll have smaller brains if they're a believer. They actually had bigger temporal lobes. And temporal lobes underneath your temples and behind your eyes, right here. That's where it's called the God area, because that's where people think they experienced them. And if you have a seizure in the temporal lobe, you have transcendent experiences,
like you're in the presence of God. And they think maybe the Apostle Paul, on the road to Damascus, had a seizure and saw God. There's actually a researcher in Canada, Laurentian University, Michael Persinger. So he would stimulate the outside.
He would do it all over the brain. But what he found, he stimulated the outside of the right temporal lobe, that people would get a sensed presence. They would actually feel the presence of God in the room. So, does that mean the brain makes up God,
or does that mean there's a way for God to communicate with us? I actually did a study on prayer. It was so interesting. a way for God to communicate with us. I actually did a study on prayer. It was so interesting. You know, I pray for you, prophecy, something called speaking in tongues, and it was fascinating.
Speaking in tongues is channeling, which means you're channeling the Holy Spirit. And the hypothesis was you'd have to drop your frontal lobes, which is exactly what happened in 60% of our patients. And one, basal ganglia skyrocketed,
just like got hit with cocaine, because that's where cocaine works, in the basal ganglia. So interesting.
If you had to create a brain-healthy nation, and I made you president of the United States for one month, and you had to put in place executive orders that would create a brain-healthy nation. What executive
orders would you immediately sign? One question. Get all of the department staffs themselves. What we're doing, is this good for our brains or bad for it. And so that's the campaign. I mean, I realize I've been doing this a very long time. If I can just get people to answer that one question with information and love, love of themselves, love of their families, love of their country,
is this, is what we're doing good for our brains or bad for it?
By far the best drug you can take for your brain, and not just your brain but your entire body, is exercise. In other words, exercise, you pump the blood and your brain gets, you know, a lot of nutrients and everything. It helps your heart. It helps your immune system. People don't realize how important that is. We're not talking about being an athlete.
We're just talking about walking, if you're older. Walking is perfectly good exercise. And, you know, children now, they're not getting enough exercise.
No, because they're on devices.
Yeah.
And so I have a model. If you want to keep your brain healthy or rescue it, you have to prevent or treat the 11 major risk factors. And we've talked about them before. Exercise helps you with every single one. So it's called bright minds.
So B is for blood flow. Increases blood flow. Retirement and aging, it decreases your age. I is inflammation. It's anti-inflammatory. G is genetics, it helps turn on health-promoting genes.
H is head trauma. If you keep walking, you're less likely to fall when you're older, right? T is toxins, sweat detoxifies you. M is mental health, exercise boosts dopamine, but it also boosts serotonin.
So it's like that perfect balancer in your brain.
Breathing, how we breathe, does that have an impact on brain health?
So you can almost immediately improve heart rate variability, which is a sign of heart health, but also goes to mental health by breathing in a certain helpful way. And I call it the 15-second breath.
So four seconds in, big breath, hold it for a second and a half, pause just a little bit. Eight seconds out, hold it for a second and a half. So if you take twice as long to breathe out as you breathe in, it increases something called parasympathetic tone,
and it just calms you down almost immediately. So if you're having panic attacks, yes you can take Xanax, but there's so many problems with that later on. Or you can just learn how to breathe, we call it diaphragmatic,
so breathe mostly with your belly, taking twice as long to breathe out as you breathe in.
Chewing. There's a piece here that says it stimulates hippocampal activity and may slow cognitive decline. Reducing chewing has been linked to impaired learning in animal studies.
And fast food decreases chewing because it's fast, so they take most of the fibre out so you can chew it faster, you can swallow it faster.
Things in the bad for your brain list. Overuse of GPS and navigation app, which weakens the hippocampus by outsourcing spatial memory long term. This can lead to atrophy in areas associated with memory and navigation.
And people are diagnosed with Alzheimer's disease later in life because of Siri. Because I used to, like when I started as a young psychiatrist, somebody would get lost in a city they'd lived in for 30 years and their family would call me upset. And I'm like, okay, this person's headed toward dementia. Now that person goes, take me home.
Do you think we're going to have an epigenetic effect of not reading maps? That if Stephen, now he uses his phone to get from A to B, do you think that's going to affect Stephen's son or daughter because dad didn't have?
Wow, okay. That never occurred to me that you could pass on something like that. By the way, I think it has to be physiological. Stress, for example, could be probably passed on. And you mentioned this, you pointed out,
during pregnancy you want to prevent stress and crisis,
right?
Do you know about that study with mice where they made them afraid of the scent of cherry blossoms from memory? And so whenever the mice smelled cherry blossoms, they would shock them, mildly. So the mice are now afraid of the scent of cherry blossoms.
Their babies were afraid of the scent of cherry blossoms. Their grandbabies were afraid of the scent of cherry blossoms. Wow grandbabies were afraid of the scent of cherry blossoms.
OK, that's the olfactory system. Olfactory system is very interesting because it goes directly to the hippocampus. There might be an evolutionary advantage because if there is something in the environment that you shouldn't eat or that smells a particular way,
passing that on is very efficient instead of having to experience that yourself, you know, trial and error, because if it poisons, it might kill you. But if your parents had that bad experience and pass it on, you shouldn't go to something that smells
in a particular way, that makes sense.
The other thing that's bad for the brain, which is unexpected, is you said at the start, artificial sweeteners. Now, start, artificial sweeteners. Now I didn't, I thought artificial sweeteners were fine.
They're not fine and they're not free. So I used to drink diet soda like it was my best friend because I thought it was free. And then I had arthritis when I was 35 and one of my patients said she stopped aspartame and her arthritis went away.
And I'm like, because I was drinking, like, I don't know, a lot of diet soda. And so I stopped, and my arthritis went away. And I'm like, no. And so I did it again, and it came back. And I'm like, OK.
And artificial sweeteners can change the microbiome. So we haven't talked about that, but you have these hundred trillion bugs in your gut that make neurotransmitters digest your food. And especially sucralose or Splenda has been found to decrease the good bacteria in your gut,
which then has a negative impact on brain function. And aspartame, as you mentioned. And aspartame, that I mentioned, that can have a generational impact. So is it possible it's really not social media? It's that we've had aspartame in our food for decades.
And I think it's all of these things that just sort of are additive, and we should just always think that one question. Is this good for my brain or bad for it? So you mentioned broccoli. Probably that's good for your brain. Cheeseburger? Probably not, but why don't you take the burger,
and if you could make it grass-fed, that would be better, and put it in a salad, and then that would be good for your brain.
What about chronic background noise?
We don't think much about the impact noise has, but. I used to live, my house was three houses from the freeway. And if you just go there, it's like, my God, it's so loud here. I never heard the freeway because my brain just learned to tune it out. By the way, was that good or bad for you?
That I was able to-
You adapted and were no longer sensitive to it. I think that actually was probably not good for various reasons because what it really means is that you're specializing for that environment and your brain's gonna be different when you go someplace. So here's another example. And it's stressful, right?
It's chronically stressful,
but my brain has figured out how to-
That's right, that's right.
In the background.
In other words, yeah, in other words, your brain is reacting to it
even though you're not aware of it.
Yeah, so ittly increases cortisol and impairs working memory and attention regulation, especially in children and older adults, to be chronically exposed to background noise like traffic or the low-level hum of a city.
Yeah, that's right. That's absolutely right.
Make sure you keep what I'm about to say to yourself. I'm inviting 10,000 of you to come even deeper into the Diary of a CEO. Welcome to my inner circle. This is a brand new private community that I'm launching to the world. We have so many incredible things that happen that you are never shown. We have the briefs that are on my iPad when I'm recording the conversation. We have clips we've never released. We have behind the scenes conversations with
the guests and also the episodes that we've never ever released. And so much more. In the circle you'll have direct access to me, you can tell us what you want this show to be, who you want us to interview, and the types of conversations you would love us to have. But, remember for now, we're only inviting the first 10,000 people that join before it closes. So if you want to join our private closed community, head to the link in the description below or go to DOACcircle.com.
I will speak to you there. Many of us multitask across multiple screens now. We're watching TV here, we've got our phone here, we've got our iPad here, got our computer here. And I was reading into the science of multitasking and it said that it trains your brain to be distractible,
reducing gray matter density in the interior cingulate?
Yeah, that's insula. In the medial prefrontal cortex.
And when the insula, the insula is so interesting, and I know you can talk about it. I have a new study coming out on hope. So on 7,500 patients, we gave them a hope questionnaire. What does that mean?
Hope questionnaire.
Hope, like how much hope do you have for the future? That you have the ability to make tomorrow better? And people with low HALT have lower overall prefrontal cortex function, but the insular was really low.
And that signal was the most statistically significant of the group, really. And in some studies, insula is called the eyelid. By the way, really. And in some studies, this is called the eyelid.
Also for depression, people who have depression have low activity in the anterior cingulate. Deep brain stimulation has been used now for to help some people, if you stimulate that area.
And what our imaging research would say is depression is like chest pain. It's not one thing. Like nobody gets a diagnosis of chest pain because that would be stupid, right? It could be heart attack, heart arrhythmia,
heart infection, gas, grief. Depression's the same way when you look at it from an imaging standpoint. Sometimes their frontal lobes are too active. Sometimes they're not active enough. Sometimes it's their limbic system that's too active.
And I wrote a book called Healing Anxiety and Depression. I'm like, here's the seven things I see as an imager.
What about ADHD? There's obviously been a rise in ADHD, or at least people reporting being diagnosed with ADHD quite significant. Can you find ADHD in the brain? Are we causing ADHD as a function of the way that we're living our lives? diagnosed with ADHD quite significant. Can you find ADHD in the brain?
Are we causing ADHD as a function of the way that we're living our lives, or is it something within the brain genetically that I could see?
So it's both. I think clearly you can see ADHD in people's families. In fact, if I have a hyperactive, restless, impulsive, disorganized, procrastinating child, I'm looking at the mom and the dad. I'm like, where is this coming from? But you could also get ADHD from a head injury,
especially if it affects their frontal lobes, which is why you shouldn't let children hit soccer balls with their forehead. You can also get it from the chronic, from the excessive input, making people distracted, just like you said, a brand new study out
on children who took medicine, right? We always demonize ADHD medicine, but the kids who took medicine actually had bigger brains in their prefrontal cortex than kids who didn't take medicine, who had AD.
Ritalin?
Ritalin.
That's, okay, it's speed, basically, amphetamines.
It is, but for the kids who have it, I think withholding medicine from a child who really has ADHD is like withholding glasses from someone who has trouble seeing. And it's the easy thing to demonize the drugs until you realize someone who has ADHD, a
third of them don't finish high school. And we never ask the right question about—people go, what's the side effects? And it can decrease your appetite and can have sleep problems with it. But they don't ask the other question, is what's the side effect of not taking the medicine or at least not fully treating it? And there are other ways to treat it besides medicine, you know, for God's sakes, I own a supplement company and I'm always trying to optimize the nutrients
to the brain. Neurofeedback can help. But if you do those things and it's not working, don't be afraid of medicine. By the way, when I was growing up, ADHD either didn't exist or they didn't know about it. Do you think that there's some link to our diet? Oh, no. It was first described around 1910. And it's in the first version of the DSM.
Oh, nice.
OK.
They called it minimal brain dysfunction. But when we were growing up, there were one or two of these kids in our classrooms. And now there's eight to 10 of them in my classroom.
That's what I mean, is that it seems to,
like autism, it seems to be proliferating. Right, and part of it, I think, is the food that is much more processed. Part of it is the screens, part of it is the distracted parents, and part of it is the teaching.
You always seem to be doing new studies, Daniel. What new studies are you most excited about, or have you completed since we last spoke?
I did one that I'm so excited about on negativity in the brain. And negativity is bad for your brain.
How do you define negativity?
We actually give them a questionnaire. It's a positivity, negativity, bias questionnaire. And people who are more negative have less activity in their prefrontal cortex. It's actually quite interesting. And so unbridled positivity is bad for you
because you need that 15%. So, unbridled positivity is bad for you because you need that 15%, but if you're chronically negative, that is bad for your brain.
Is there a link between being a negative person and Alzheimer's and dementia?
Yes, and what's interesting, because you mentioned a gender difference earlier, if you're depressed and you're a woman, it doubles your risk for Alzheimer's disease. If you're depressed and you're a man, it quadruples your risk.
Wow.
So there was a study that was done during the COVID years, a couple of years, and it turns out that the rate of depression doubled in women,
but not in men.
During COVID.
During COVID. And after COVID, when the students came back and everybody was back to normal, so-called normal, the women stayed depressed at that high level, which is very interesting. They should be the women who suffered the most.
So in one study, women had 52% less serotonin than men, which I think is really interesting. Women by and large have double the risk of depression. Women have double the risk of depression as men. Their limbic systems are larger, which is also involved in-
Okay, more vulnerable probably. More vulnerable and bonding. And then the whole COVID thing we haven't talked about. COVID causes inflammation in the limbic part of the brain. I had scans of people I was treating, and then they got COVID, and then I scanned them again,
and you can just see this dramatic inflammation in the brain.
If someone's listening now and they just want to improve their brain health, they want to avoid dementia, they want to be cognitively powerful and capable as they age, they want to get to 80 years old, 90 years old, 100 years old, and have a great brain, and you just had to, and you could only tell them to do three things.
Well, Terry said one, exercise.
Okay, exercise, I'm gonna do it.
Start every day with today is going to be a great day.
Positive.
Push your brain to look for what's right rather than what's wrong.
Okay, so I'm gonna be optimistic and grateful.
Omega-3 fatty acids. And either do it with fish or do it with a supplement.
Why did you include omega-3 fatty acids?
Because it decreases inflammation and 25% of the cell membranes in your brain are made up of omega-3 fatty acids. And as a country, we're dramatically low on them.
And learning, that's maybe one of the things that's been left off the list of top three things. But I mean, I remember you telling me that how good learning was for the brain, and even getting outside and running outside versus running on a treadmill is more beneficial.
And if you learn while you're exercising, what you're doing is you're getting blood flow to the hippocampus and you're more likely to remember it. So-
I heard this, yeah. I heard someone tell me that they figured out that they could learn better for their exams if they did it in a sauna. So they kept, it was a scientist that I spoke to, she said she keeps learning new information
when she's in the sauna, because she realized that when she left the sauna and was then tested upon it, she was better able to do the exam. And I guess that's correlating to what you said about, because in a sauna, you're gonna have a lot of blood flow,
I imagine, to the brain.
Yes, there's actually a study in JAMA psychiatry that one sauna bath helped depression, significantly helped depression. And I think it's because of it's balancing the brain and people who do the most saunas have the lowest risk of Alzheimer's disease.
What is the most important thing as it relates to the subjects that we spoke about today? AI, the brain, neuroscience, that you would like to say to the subjects that we spoke about today, AI, the brain, neuroscience, that you would like to say to the people that are listening now, there could be a million people listening, there could be 20 million people listening.
If you could say one thing to them about the brain, AI, neuroscience, whatever you wanna say, the floor is yours. What would that be? Over to you first, Terry.
Sleep.
Sleep is a time when the body not just regenerates, but your memory is consolidated. So things you've experienced during the day are integrated into your cortex. And it's an interaction between the hippocampus and the cortex for episodic memories.
And it's unfortunate. What's happening with children now, they're so competitive to get into college that they're cutting back on their sleep and it's just the wrong time of your life. You shouldn't be cutting it back
when your brain is developing. So those two things, I would say sleep and exercise
are the most important thing for your brain.
The floor is yours. What would you say to the listeners about all the things we've talked today? What's your closing statement?
Well, you know, I go back to what I talked about in the beginning, which is we've just thrown the barn door open and let the horse bolt out into our schools, into our businesses, into our homes.
And before we've been asked, is it a gift into our schools, into our businesses, into our homes.
And before we've been asked, is it a gift or is it a Trojan horse that's gonna steal from us? We've embraced convenience before understanding consequence. And we've done it before with video games and cell phones and social media and marijuana and alcohol and opiates and high fructose corn syrup and aspartame.
And we have to be smarter. We have to tame this horse. It's gone with wisdom or it's going to trample our children. And so I think we have to be very thoughtful. And it all comes back down to is this good for my brain or bad for it? Is it good for our collective brains or is it potentially bad for it?
And just answer that question with information and love of yourself, of your family, of your country, community. Yeah, I'm more anxious than when I came in. I don't like that.
It's so front of mind for me at the moment because I have the hindsight, the wisdom of hindsight of all those things you mentioned like exercise and processed foods and social media and all these things that we tried and they all seem to follow a similar arc. Some kind of new product or discovery is made. The early phase, in the early phase, people who have an incentive for that thing to be successful will somewhat like gaslight you
into thinking that it's fine. And then we get into the second phase where we start to see sort of some consequences. Then we study what's actually happened. We figure out that there was always a trade-off, and that nobody really understood the trade-off, and then people change their behaviour.
So now when I go into these new technologies where the short-term benefit is really clear, it's making me more productive, I pause and I go, there's going to be a trade-off here. There's always a trade-off. What is the trade-off? And am I comfortable and conscious of what that trade-off is?
And if the trade-off... So I try to figure out what the trade-off is with things like AI, and I go, okay, the trade-off is probably I'm going to be worse at critical thinking, and that might have an impact on my social relationships And I really value my critical thinking. I really value my ability to solve problems and to articulate myself and to write
and to communicate with my loved ones in an effective way. So what can I do if that is the trade-off now? And one of the things that I'm doing now feels really counterintuitive in a world where everybody's got these productivity gains because they're using these tools, which is to refrain.
And I wonder if one of the great advantages of the next decade, one of the great hedges for anyone that's wanting to be a great critical thinker, entrepreneur, creative, is to go left when everyone's going right, which is to refrain and do it the hard way. And if we look at history in these arcs that we've discovered with food and with exercise and all these things and dating, doing it the hard way, like we said about the marshmallow
test and delaying the gratification, seems to yield the greatest returns. So I think I'm gonna do it the hard way.
And it would be the easiest because it won't have the side effects.
Yeah, the hard way.
I wanna feel good now and later, as opposed to now, but not later.
And to be clear, this doesn't mean I'm not going to use AI or chatGBT. It just means that when it matters, when the thinking matters, I will think for myself. And when the communication matters, I'll communicate for myself.
That's my conclusion.
You should hope that your children will feel the same way when they grow up.
That they will model what you do, right? Every day you model health or not health.
Thank you. Thank you for writing two, well, many incredible books that I've got around me. I'm gonna link them all for my viewers that are watching. I've got so many of these books The incredible one that you wrote for parents called raising mentally strong kids. You've got your other book over there change your brain Every day and I've got this book here from from Terry which is the deep learning revolution and one you wrote most recently called
Chachi pity in the future and one you wrote most recently called Chachapiti and the Future of AR. I'm gonna link all of them below. I'm gonna link them with a little bit of a summary of what's in them. So if you decide that there's anything here that we talked about today where you wanna dig in further, please do dig in. And I'm also gonna link both of your,
a link to where people can find out more about both of you, your websites and more of your work in the comments below. Please do check that out, everybody listening. We have a closing tradition where the last guest leaves a question for the next guest, as you know, and they don't know who they're leaving it for. So I'm gonna ask you both a question, starting with you, Daniel. Are you prepared for recognition
of your next health challenge? Will you be able to notice its onset and how will you address the challenge, even if it means a major lifestyle change or way
of living? Okay. Yes.
How will you address the challenge, even if it means a major lifestyle change or way of
living? Well, I'm very clear on the goals I have, which is to be vibrant and healthy and not get dementia. So if I need to change something so that happens, I'm all in.
Are you prepared?
Probably not. No, I've been blessed with good health. I try to live a healthy life. But the problem is that you can't anticipate, as you get older, what's ahead. You mentioned arthritis.
I'm feeling a little bit of arthritis now. I've been arthritis-free all my life. And that's something that's very difficult. To realize that it's coming, that there's very little you can do about it, is depressing. But on the other hand, things could always be worse.
Sometimes that cheers you up. But the reality is that there are things in the world, like COVID, that you have no control over, that may, or an accident, or Alzheimer's, God forbid, who knows what will happen. You have to live with whatever life deals with you.
You know, the time that you have, you should really spend on trying to make it a healthy life, a productive life, a satisfying life. And that's something that we have control over, right?
What are you scared of?
Right now, it's China.
I'm not being facetious.
I think that it's a threat that is a societal threat. It's not, I don't think that it's going to affect me. And I've had great Chinese students, and so I really like, I think the Chinese people are different from what I see as the country, what they're trying to do, the goals that they're taking.
20 years ago, if you look at the, of all the technical areas in physics and chemistry and biology and so forth, the 100 most important advances have been made. 20 years ago, it was like the Americans had 94 of them. This year, it's 74 are Chinese.
And that's because they made a huge investment in science and STEM research. They poured out a million engineers to implement AI. They're doing the right thing. We did that. Remember when the Sputnik went over, the Sputnik moment?
We made a huge investment in STEM, in science and engineering and in education.
What was the Sputnik moment?
Oh, okay, 57, when the Russians put a satellite that went over the US over and over again. We didn't, it took us years to put up our own satellite because we had fallen behind. But that investment we've been living on, literally, for the last 60 years.
And now the Chinese have done that and they're gonna be advanced and they're gonna be way beyond us. You asked me, okay, that's something I'm very, very disappointed in our country that we're not, in fact, we're just doing the opposite.
We're tearing apart science right now with the president administration.
What are you scared of, Daniel?
Losing my wife. That's the most, it's the thing that comes to mind. And when I was thinking about China, my mother-in-law was a prepper.
A prepper being someone that's preparing for the end of the world.
Prepared for the end of the world. And we were in Egypt last year and got a call that she had cancer, and we were there for three days and came home. And I kept thinking, I loved her dearly, I'm like, you prepared for the wrong thing. You should have prepared for cancer.
Like, I think every day we should be... And the same Alzheimer's prevention program is a cancer prevention program. It's a heart disease prevention program. It's a diabetes prevention program. And I'm like, she's prepared for the wrong thing. The thing you really want to be prepared for is disease, right? And I know I'm gonna die. I just wanna be vital for as long as I can be.
And hope is, well, I have a say in this, right? Because I know I can accelerate my body's decline or I can decelerate it. And I'm gonna choose to decelerate it.
Thank you. Thank you.
We're done.
