Don't Let Artificial Intelligence Steal Your Intelligence
Home / Blog /
I want to start with a warning. Not about artificial intelligence itself — but about what happens to your brain when you stop doing the things AI can now do for you.
I have spent nearly four decades studying the human brain, first at Johns Hopkins and then at Harvard Medical School, and the single most dangerous misconception I encounter — in patients, in students, in the brightest people I know — is the belief that the brain is like a computer. That it arrives at its peak somewhere in early adulthood, runs well for a while, and then inevitably begins to slow.
That is simply not true. And in the age of AI, it is a misconception with consequences we are only beginning to understand.
Your Brain Is Not a Computer
A computer is a fixed system. You can upgrade its parts, expand its memory, replace its components — but its fundamental architecture does not change in response to how it is used. The brain does exactly the opposite.
Your brain is a living organ. At a microscopic level, it is changing right now — building new connections, reinforcing pathways that are used, and allowing pathways that are neglected to quietly weaken. This is not a metaphor. This is the biology.
There is a structure deep inside your brain called the hippocampus. It is roughly the size of your thumb, tucked at the base of the temporal lobe, and it is the engine of your memory and learning. What the science shows with clarity is this: the hippocampus grows when it is challenged, and it shrinks when it is not.
London taxi drivers who spend years memorizing every street and shortcut in one of the most complex urban environments on Earth have measurably larger hippocampi than average. The same has been documented in people who learn a new language, master a musical instrument, or take on demanding cognitive tasks that require navigating genuine uncertainty.
Use it, and it grows. Neglect it, and it atrophies.
That is not a figure of speech. That is what the MRI shows.
The Two Ways to Use AI
I am not here to tell you that AI is dangerous. It is not — not inherently. And it is not going away. We are living through the most remarkable technological revolution in human history, and I believe AI will continue to grow more powerful, more capable, and more integrated into how we work and live.
But there are two fundamentally different ways to engage with it — and they have opposite effects on your brain.
The first way is to use AI as a thinking partner. You engage with it to explore a subject more deeply, to process vast amounts of information, to pressure-test your own reasoning, to evaluate what is true and what is not. In this mode, your brain is working. You are bringing your own knowledge, your own judgment, and your own curiosity to the interaction. Your hippocampus is engaged. This kind of use is healthy.
The second way is to use AI as a substitute for thinking. You ask it to write the email you could have written yourself. You ask it for directions before you leave, instead of making even a partial attempt to recall the route. You let it summarize the article rather than reading it carefully and formulating your own understanding. In this mode, your brain is bypassed — not extended. And every time it is bypassed, the mental muscle that would have done that work gets a little weaker.
None of these individual shortcuts feel consequential. That is precisely what makes them worth paying attention to.
What I Do Personally
I want to be transparent about something. Everything I am about to share with you, I do not prescribe from a distance. I practice it myself — as an experiment I am running on my own brain.
I memorize phone numbers. I memorize credit card numbers. I make a deliberate point of learning the names of everyone I meet — the bank teller, the waiter, the colleague I just crossed paths with at a conference. None of this takes extraordinary effort. But each of these small acts requires my brain to encode, hold, and retrieve information rather than outsourcing that work to a device.
I deliberately skip GPS when I already know, or can reasonably figure out, how to get somewhere. When I write — whether it is a paper, a talk, or a message — I write first, and then I ask AI to critique what I have written. Not the other way around.
And I dance once a week with my wife.
I mention dancing specifically because I want you to understand what is happening in the brain during that hour. You are listening to music and tracking rhythm, which activates the auditory and motor cortices simultaneously. You are coordinating movement with another person, which requires continuous social and spatial processing. You are staying present and responsive to what your partner is doing in real time. You are navigating physical space. The brain does not experience this as recreation. It experiences it as one of the most complex, multi-layered demands you can place on it. Neuroscience loves that kind of demand.
The broader point is simple: there are opportunities to exercise your brain woven into every day. The question is whether you take them, or whether you hand them to AI.
What I See in the Clinic
Every day, I meet patients in their fifties and sixties who are frightened. Their memory is slipping in ways that feel new. Their thinking feels slower. They come in wanting to know whether what they are experiencing is the beginning of Alzheimer’s, or something else — something that might be reversible.
What I tell them, backed by research and by the results of my clinical experience treating thousands of patients, is this: your brain has not given up on you. But you may have given up on your brain.
Prevention is not a pill. It is a practice. It is a daily decision to challenge yourself rather than to offload the challenge. To be curious rather than comfortable. To make your brain work for the answer rather than reaching for something that will retrieve it instantly.
The research is clear on what works: aerobic exercise triggers the growth of new brain cells in the hippocampus. Deep sleep activates the glymphatic system, which clears the toxic proteins associated with Alzheimer’s. Stress management protects the hippocampus from the long-term damage of cortisol. Nutritional strategies — particularly the Mediterranean and MIND diets — have been shown to meaningfully reduce the risk of cognitive decline. And cognitive training, the kind that is genuinely challenging rather than merely familiar, builds the neural reserve that protects your brain as it ages.
These are not luxury habits for people with extra time. They are the practices that determine what kind of brain you are living in at seventy, at eighty, at ninety.
The Most Transformative Technology You Already Own
AI will keep improving. It will become more capable. It will continue to offer to do things that your brain used to have to do itself. And there will always be a case for letting it — in the right context, for the right tasks.
But here is what no algorithm can replicate: the feeling of solving a hard problem and finding your way through it. The satisfaction of remembering something you worked hard to learn. The confidence that comes with a mind that has been trained, stretched, and trusted.
Your brain is not a relic of a pre-AI world. It is your greatest asset. And unlike every device you own, it does not become obsolete with use. It becomes more powerful every time you demand something of it.
So make the demand — every day. Learn something new. Memorize something that feels unnecessary. Write the email yourself. Take the route without the GPS. Dance. Engage. Challenge.
The most transformative technology available to you is not in your pocket. It has been with you since the day you were born.
Protect it. Train it. Trust it.
The more you use it, the stronger it gets.

Menopause, HRT, and Your Brain Fog
What if the brain fog you’re feeling in your 40s or 50s isn’t just normal aging, but your brain reacting to the hormonal changes of menopause?
I want to tell you about a patient of mine, and about two brand-new studies that are changing how we think about hormones, menopause, and Alzheimer’s disease. The answer is more encouraging than you might think. Stay with me to the end, because I’ll also tell you exactly what I would do if I were you.
A few years ago, a lawyer in her late 40s came to see me.
She told me she felt slower handling her cases. She was less articulate than she used to be. She kept forgetting things: appointments and why she’d walked into a room. Her mother had died of Alzheimer’s, and she was terrified she was next. She wanted me to fix it, immediately.
She was serious. She was panicked. And honestly, I understood why.
I’ll tell you what we actually found, and what happened to her, later in this article. But first, let me explain what’s happening in women like her.
Why Menopause Can Change How Your Brain Feels
When a woman goes through menopause, her estrogen levels drop dramatically.
We usually think of estrogen as a reproductive hormone. But it does far more than that. There are estrogen receptors throughout the brain. Estrogen helps brain cells communicate with one another. It supports the connections between neurons. It affects the neurotransmitters involved in mood, sleep, and memory. It even influences the parts of the brain in charge of temperature regulation, appetite, and weight management.
So when estrogen falls during menopause, it makes sense that some women notice changes in how their brain functions. It makes sense that they might experience brain fog, trouble finding the right word, mood swings, or a feeling of being less sharp than they used to be.
Many women also experience hot flashes, weight gain, sleep apnea, and metabolic issues around this time, all of which can affect memory and thinking indirectly.
For years, scientists have wondered whether losing estrogen might help explain why women are so much more likely than men to develop Alzheimer’s disease. We still don’t have a definitive answer. But two brand-new studies are giving us some real clues. If you’ve heard conflicting things about hormone replacement therapy over the past twenty years, these two studies are a big part of why that conversation is finally starting to change.
Two New Studies Worth Knowing About
The first was published on August 12 in the journal Neurology, by researchers at Stanford.
Instead of simply asking women whether they had memory problems, the researchers looked inside their brains. They studied more than 21,000 women, including thousands whose brains were examined after they passed away. Women who had used estrogen-only hormone therapy had 35% lower odds of showing Alzheimer’s-related damage in their brains, and 39% lower odds of ever being diagnosed with any form of dementia.
The second study was published on August 26 in the journal Alzheimer’s & Dementia. Researchers from the University of Exeter and the University of East Anglia followed more than 183,000 postmenopausal women in the UK for over 13 years.
Women who had used HRT had a 16% lower risk of Alzheimer’s disease. And among women who had gone through a surgical menopause, those who used HRT had about a 26% lower risk of developing any form of dementia. This study found the biggest benefit in women who started HRT between the ages of 46 and 56.
Both studies point to something researchers call the window of opportunity. The idea is that estrogen may help the brain most when it is started around the time of menopause, rather than decades later. In other words, timing may matter more than we used to think.
I do want to be careful here. Both of these are observational studies. They show an association between hormone therapy and lower dementia risk, not proof that HRT prevents dementia. The researchers behind both studies have said the same thing, and they’ve called for randomized clinical trials to test the question properly. I agree with them. But after twenty years of fear and confusion around this topic, findings this large and this consistent are genuinely reassuring.
What Actually Happened to My Patient
Now, back to the terrified lawyer: she had Alzheimer’s.
Her workup told a very different story than the one she feared. She was sleeping poorly. She was working full time, raising three teenage sons, and taking on extra projects after hours to try to earn a promotion. On top of all that, she had gained weight, and she was not exercising.
When we went through it together, she understood that her symptoms were not caused by Alzheimer’s disease. They were the product of exhaustion, stress, poor sleep, and a body under strain. And that meant they were fixable.
She completed our 12-week Brain Fitness Program, and my brain coaches helped her improve her exercise routine, her diet, her sleep, her stress levels, and her brain training. In parallel, her own doctor started her on hormone replacement therapy.
Twelve weeks later, her memory had gone from the 40th percentile for her age to the 80th percentile. She was thrilled. And she stopped worrying about Alzheimer’s disease.
Her story is the whole point, really. Her fog was real. But it was not what she was most afraid of, and it responded to the right combination of changes.
So Should You Take HRT to Protect Your Brain?
This is the question I get most often, so let me answer it honestly.
Not for that reason alone, and not yet. We do not yet have the gold-standard proof from a randomized clinical trial to recommend HRT specifically for cognitive symptoms.
But if you are also struggling with hot flashes, vaginal dryness, or other menopausal symptoms, then HRT for a couple of years can be a very reasonable option, one worth discussing seriously with your doctor. And these new studies are reassuring, not alarming.
Please keep one thing in mind. Your brain does not exist in isolation. Sleep, exercise, nutrition, stress, brain training, and your hormones are all connected. Hormones may be one piece of the puzzle, but they are not the whole picture, exactly as I saw with my patient.
What I Want You to Do
If you are at this stage of life and wondering whether HRT is right for you, talk to your doctor about your own personal history and risk factors. That conversation is the single most important next step you can take. Every woman’s situation is different, and this is a decision to make with a physician who knows your history, not one to make from a newsletter or a video.
And regardless of what your hormones are doing, you should always work on the five pillars of brain health:
- Walk daily, and exercise about three hours a week.
- Sleep 7 to 8 hours a night.
- Eat a Mediterranean diet.
- Reduce your stress, and consider meditation or yoga.
- Challenge your brain with a fun hobby at least once a week.
The fog you’re feeling is not a life sentence. Very often, like it was for my patient, it’s a signal, and a signal is something you can act on.

AI Is Changing Your Brain, Here's How.
How many days do you think it takes to start losing a skill you’ve had for decades?
For me, the answer was three.
A few weeks ago, I got into a self-driving car for the first time and let it take me around my town. It was smooth. It was relaxing. And honestly, it was a little bit magical. I sat there with my hands barely on the wheel, watching the car make its own decisions.
Three days later, I got behind the wheel of my own car again. This time with no assistance. Just me. And something felt off. It was slightly difficult to manage the heavy traffic on a busy highway. My sense of the road felt a little rusty.
It had only been three days, and I could already feel the difference.
That small moment stuck with me. Because as a neurologist who has spent forty years studying the brain, I knew exactly what was happening. My brain had not lost the skill of driving. But the parts of my brain responsible for it had quietly relaxed, because for three days they simply did not have to work that hard.
Negative Neuroplasticity: The Part Nobody Talks About
This is what I call negative neuroplasticity.
Your brain is not fixed. It is not a piece of hardware that stays the same your whole life. Your brain is living tissue, and it changes its shape, its structure, and its strength based on how you use it every single day.
Think of your brain like a muscle. If you work your biceps and triceps, they grow. If you stop using them, they shrink. Your brain grows and shrinks in the same way, in response to your lifestyle and your environment. The parts you use and challenge often get stronger. That is positive neuroplasticity. The parts you stop using quietly fade and shrink. That is negative neuroplasticity.
And we have seen this before, long before AI arrived.
When calculators became common, our collective ability to do math in our heads got weaker. When GPS became common, our sense of direction got weaker too. So here is the honest question all of us need to ask: if AI can now write our emails, solve our problems, remember our facts, and even drive our cars, what happens to the parts of our brains that used to do all of that work?
What the Research Is Starting to Show
There is new research beginning to answer that question, and the results are worth paying attention to.
In one study, researchers had people write essays in one of three ways: completely on their own, using a search engine, or using ChatGPT. The whole time, machines measured their brain activity. The group that used ChatGPT showed the weakest brain engagement of the three. And afterward, many of them could barely remember what they had just written, because in a very real sense, they had not actually written it themselves.
We are seeing the same pattern in medicine.
In one study, experienced doctors used an AI tool to help them spot polyps during colonoscopies. After they grew used to working alongside the AI, their detection rate without it actually dropped, compared to how they performed before they ever used the tool. These were skilled physicians, quietly losing a bit of their edge, simply because the tool had been doing that part of the thinking for them.
To me, this all makes perfect sense. The activity in the parts of our brain that we stop using and challenging gradually fades away.
This Is Not About Fearing AI
I want to be very clear about something, because this is not a message about fearing AI or rejecting it.
I use AI every single day. I think of it almost like one of my staff members. I let it handle the tedious, minor parts of my work, the things that do not require my judgment or my creativity. But I still do the hard thinking myself. The writing. The decisions. The real work. Because I know that “use it or lose it” applies to my brain just as much as it applies to my muscles.
Here is the strange thing. We already understand this instinct perfectly well when it comes to our bodies. We just have not caught up yet when it comes to our brains.
Think about how life used to require constant movement. People walked to work. They rolled their windows up with their own hands. They pushed in a clutch and changed gears with their own feet, over and over, every time they drove. All of that built-in movement quietly kept our bodies strong, without anyone ever thinking of it as exercise.
Today, machines do almost all of that work for us. We press a button, and the window rolls up. We slide into an automatic car and never touch a gear again. And what did we do as a society, once daily life stopped giving us that movement for free? We built gyms. We started going to Zumba classes, yoga classes, and Pilates. We began taking long walks on purpose, specifically to give our muscles the workout that daily life no longer provided automatically.
This is exactly the position we are now in with our brains.
AI is quietly becoming the automatic window button and the automatic transmission for our minds. It removes the friction, and it feels wonderful in the moment. But if we are not careful, we are quietly losing the mental exercise that daily life used to give us for free, when we had to remember phone numbers, do math, navigate our own cities, and write our own thoughts from a blank page.
Six Ways I Build a Gym for My Own Brain
So, just as we built gyms for our bodies once our environment stopped providing free exercise, we now need to build a gym for our brains. These are small, deliberate exercises we choose on purpose, precisely because daily life no longer forces us to do them.
Here are six exercises I personally do. Not because I read them in a textbook, but because I know they are important for keeping my own brain sharp.
1. I minimize using GPS on purpose: When I am driving somewhere I have been before, I make myself recall the way, even if it takes an extra moment of thinking. That small effort keeps my hippocampus and other memory areas active and engaged.
2. I memorize names: I work to remember the names of all my students and every person I meet, every single day. Holding a name in my mind and pulling it back later sounds almost too simple to matter. But that daily repetition is exactly what keeps my memory strong, the same way a short walk keeps my heart healthy.
3. I protect at least one block of deep, unassisted thinking: No AI, no shortcuts. Just my own mind, working hard on a project from beginning to end.
4. I keep authorship of anything that truly matters. I let AI carry the tedious, minor parts of my work, but the real writing, the real decisions, and the real thinking stay mine.
5. I take up hobbies that challenge my mind: Learning new dance steps is at the top of my list, and this one is for pure joy as much as it is for my brain. I am willing to bet you already have a small wish list in the back of your mind, something you have always wanted to learn from scratch or finally get better at. The science is clear that a new, challenging skill grows your brain in a matter of weeks. So pick the one hobby that sounds the most fun, and enjoy practicing it until you get really good at it.
6. I use AI to challenge me, not replace me: After I write an essay or prepare a presentation, I ask AI to critique my work and push back on it. I also use AI as a tutor when I need to understand something complex. In other words, I use AI to stimulate my brain, not to replace it.
The Brain You Have Is the Result of Your Daily Choices
So here is what I want to leave you with.
AI is not going to make you stupid. But how you use it will absolutely shape whether your brain stays sharp or slowly grows weaker.
Your brain, like your body, becomes what you ask of it every single day. The brain you have, sharp or dull, strong or weak, is the result of your daily choices. Just as the shape of your body is in your hands, so is the shape of your brain.

What Is a Brain Portfolio?
Let me start with a simple question.
If you were managing a $10 million investment portfolio, would you put all of it into a single stock?
Of course not. You would diversify. You would spread your money across different types of assets. You would manage your risk, monitor your performance, and make adjustments over time. That is simply what anyone serious about money does.
Now I want you to think about your brain the same way.
Your Brain Is an Asset
Your brain is an asset too. In fact, it may be the single most important asset you have. It allows you to think, make decisions, solve problems, lead your organization, manage your finances, and maintain your relationships.
And yet most of us do not manage our brain the way we manage a financial portfolio. Instead, we wait. We wait until there is a problem. We wait until our memory starts to slip, or until we are exhausted, stressed, and burned out. And only then do we ask, “What can I do about it now? Do I have early signs of Alzheimer’s disease?”
I believe we should approach brain health very differently. We should look at the brain the way we look at a financial portfolio. I call it your brain portfolio.
Just as a financial portfolio has different asset classes, your brain portfolio has five major assets: exercise, sleep, diet, stress management, and brain training.
And the key idea, the one I want you to hold onto, is diversification. You do not want to pour all of your brain health investment into a single area. Exercise is extremely important, but exercise alone is not enough. A good night’s sleep is important, but sleep alone is not enough. Eating well is important, but diet alone is not enough. You need to invest across all five. Each one contributes something different, and together they build a far stronger brain.
Let me walk you through each asset.
Asset One: Exercise
Think of exercise as one of the highest-performing assets you have.
When you exercise, you are not simply strengthening your muscles and your heart. You are increasing blood flow to the brain, supporting the growth and maintenance of brain connections, and helping to regulate blood pressure, glucose, and inflammation, all of which matter for optimal brain health.
Exercise also helps grow new neurons in the hippocampus, the memory center of your brain. And it strengthens the frontal lobes, the regions critical for emotional regulation and decision-making.
So exercise is not just a fitness investment. It is an important investment in your brain capital.
Asset Two: Sleep
Sleep is your brain’s maintenance department.
While you sleep, your brain is not shutting down. During deep sleep, your brain clears out the metabolic waste that accumulates throughout the day. This remarkable cleaning and rinsing process is your brain’s waste management system. At the same time, the parts of your brain responsible for consolidating memories, regulating emotions, and making decisions are refreshed and restored.
If you consistently under-invest in sleep, eventually you pay the price. The waste that does not get rinsed out accumulates night after night, week after week, year after year. Over time, that buildup contributes to significant brain shrinkage.
Regularly sleeping fewer than six hours a night carries serious long-term consequences, including an accelerated risk of developing Alzheimer’s disease.
Asset Three: Diet
I think of diet as the raw material your brain uses every single day.
Your brain requires energy, essential fats, vitamins, minerals, and other nutrients to function properly. A good diet provides the building blocks for your brain cells and blood vessels.
So when you choose what to eat, you are not simply deciding what goes into your stomach. You are deciding what resources you are providing to one of the most valuable organs in your body. You are supplying the raw material your brain needs to function at its peak.
Asset Four: Stress Management
Your fourth asset is stress management, and I think of it as risk management for the brain.
Some stress is normal and even healthy. But chronic, unmanaged stress can become a major risk factor for both mental and physical health.
You do not need to eliminate every stressful situation, which is neither possible nor the goal. What you need is to reduce stress where you can and learn to manage the rest effectively. That means learning how to recover from stress: creating periods of calm, maintaining meaningful relationships, and making sure your brain has enough time to recharge.
Asset Five: Brain Training
The fifth asset is brain training, and here the rule is simple: your brain is a use-it-or-lose-it organ.
When you learn something new, you challenge your attention and stimulate the parts of your brain responsible for problem-solving. When you play music or take on intellectually demanding activities, you give your brain the chance to build new neural networks.
The regions you stimulate with new hobbies and new learning, such as picking up a new language, literally grow larger. It works just like your muscles, which grow in proportion to how much you challenge them with exercise.
Your brain remains an active, adaptable asset throughout your entire life, not just in childhood. You can expand and grow your brain at any age.
The Real Power Is in the Portfolio
Here is the part that matters most. These five assets do not operate independently. They interact.
Exercise can improve your sleep. Better sleep improves your attention and emotional regulation. A healthy diet supplies the energy and nutrients your brain needs to function well. Stress management improves both your sleep and your decision-making. And brain training gives your brain the stimulation it needs to stay adaptable.
The real power comes from the portfolio as a whole.
This is exactly how we think about financial diversification. We do not ask, “Which single stock will make me rich?” We ask, “How can I build a diversified portfolio that performs well and manages risk over time?”
We should ask the same question about our brains: How can I build a diversified brain portfolio that helps me maintain my memory, focus, creativity, resilience, and independence as I grow older?
Monitor, Rebalance, and Start Now
There is one more principle from finance worth borrowing. You need to monitor your portfolio.
You do not invest once and forget about it. You review your performance, identify your weaknesses, rebalance, and make adjustments when your circumstances change. The same should be true for your brain health.
Maybe your exercise is strong, but your sleep is weak. Maybe your diet is excellent, but you are carrying too much chronic stress. Maybe you are physically active but intellectually under-stimulated.
The goal is not perfection. The goal is balance.
And you may be wondering when the best time is to start paying attention to your brain portfolio. The answer is now. When it comes to your brain, prevention is a far better strategy than waiting for a major problem to appear.
A Note for Executives and Leaders
For executives, business leaders, and CEOs, I think this concept is especially important.
You spend your professional life managing financial assets, human capital, operational risk, and long-term growth. But none of those assets matter very much if your own brain is not functioning at its peak. Your brain is the executive system behind every single decision you make.
So I encourage you to think about your brain the same way you think about your financial portfolio. Diversify. Invest consistently. Manage your risk. Monitor your performance. And rebalance when necessary.
Your brain is not simply another organ in your body. It is the most important asset you have, and it is built to grow and expand throughout your life.
Look into the five pillars of your brain health and build a brain portfolio that will last you a lifetime. The earlier you start, the more likely you are to enjoy strong cognitive returns for many years to come.
That is how you become not just a successful executive, but a brain super ager.
