The Best Morning Routine for a Sharper Brain
What you do in the first hour after you wake up matters more for your brain than anything else you do all day.
I know that sounds like a big claim. But once you understand what’s happening inside your head first thing in the morning, I think you’ll agree, and you’ll want to treat that hour differently starting tomorrow.
Let me explain the science, and then walk you through the exact four-step routine I recommend.
Why the First Hour Matters So Much
While you sleep, your brain runs a kind of cleanup crew called the glymphatic system. It flushes out the cellular waste your neurons produce throughout the day. So the moment you wake up, your brain is at its cleanest and most primed state.
That’s exactly why the first hour of your day carries so much weight. Your brain doesn’t just react to your day; it helps create it. What you feed it in those early minutes, in thoughts and in actions, sets the tone for everything that follows.
Here’s how I recommend using that hour, step by step.
Step 1: Don’t Rush Out of Bed
When you open your eyes, resist the urge to jump up, and whatever you do, don’t reach for your phone yet.
Instead, take a few minutes to think through your life. I like to focus on three sets of thoughts.
First, reconnect with your passions and your long-term goals. Visualize the life you’re working toward and the things that bring you the most joy.
Second, remind yourself that you’re capable of far more than you give yourself credit for. Most of the people you admire got where they are through effort, not luck. You can achieve any goal you set for yourself.
Third, tell yourself that things today will work out in your favor. Picture having a great day. And remind yourself that even when setbacks happen, they often become the first step toward something better.
A couple of minutes of this is enough to shift your whole mindset before your feet even touch the floor.
Step 2: Breathe and Feel Grateful
Still in bed, spend about five minutes on slow breathing or a short meditation.
Use this time to think about all the wonderful things you already have in your life. As you take each deep breath, remind yourself how fortunate you truly are. This isn’t about ignoring your challenges. It’s about setting the emotional tone of your day with energy and enthusiasm instead of stress and rush.
This step matters more than it might seem, and here’s why.
Chronically high levels of the stress hormone cortisol are toxic to your brain. When cortisol stays elevated day after day, it acts almost like a slow poison to the hippocampus, the part of your brain responsible for learning and memory, and the very region that shrinks first in Alzheimer’s disease.
A few minutes of gratitude and calm breathing is one of the simplest ways to keep that stress response in check. You are, quite literally, protecting the part of your brain you rely on to stay sharp and remember your life.
Step 3: Get Up and Move
By now you’ve spent about seven minutes still in bed, and your mind is already in a good place. Now it’s time to actually get up and move.
If you can, do some exercise or yoga every morning. A short run, a bike ride, a swim, or a simple stretching routine gets your neurons firing even if it’s only for 10 to 15 minutes.
If morning exercise isn’t possible for you, use this time for your daily family routines instead, like getting the kids ready for school. Either way, you’re moving your body and your mind into the rhythm of the day. Consistency matters far more here than intensity.
And if you need to check your emails or messages, this is the time. But don’t waste any of your precious morning on social media.
There’s real evidence behind the exercise piece specifically. A 2024 study found that twelve weeks of exercise was associated with significant changes in the hippocampus and improved neuroplasticity, your brain’s ability to learn and adapt. Your muscles aren’t the only thing that gets larger and stronger when you exercise. Your brain does too.
Step 4: Fuel Your Brain
Once you’ve moved your body or handled your morning chores, it’s time to eat.
An ideal breakfast for a sharper brain is built around protein and fiber, with coffee or tea if you like. You can alternate through the week so it never gets boring. One morning, try an omelet with vegetables and a slice of whole-grain toast. Another, oatmeal with blueberries and milk.
Rotate in nuts, berries, olive oil, leafy greens, poultry, or fish when you can. These are staples of the Mediterranean diet, which research shows can slow cognitive decline.
None of this requires a complicated meal plan. It just takes a little intention before you walk out the door.
The Bigger Picture: You Can Shape Your Brain
Having gone through a series of rejuvenating thoughts, some movement, and a healthy breakfast, you head out the door full of energy, ready to take on the world.
Here’s what I most want you to remember. Neuroplasticity is the most remarkable property of the human brain. It means you are not stuck with the brain you have today. You can actively shape and strengthen it, improving both how you experience life right now and how sharp you stay decades from now.
The morning is the single best window each day to prime your brain for the highest levels of neuroplasticity. And the routine itself is not complicated:
Warm up your mind with positive thoughts for two minutes. Add five minutes of deep breathing and gratitude. Move your body for 10 to 15 minutes. Finish with a high-protein, high-fiber breakfast. Then step out of the house full of positive thoughts and energy.
These four simple morning steps will help you have a great day today and stay sharp for years to come.

What Sugar Really Does to Your Brain (and How Ozempic Fits In)
What if I told you that eating a donut can do something to your brain that looks a lot like what cocaine does to it?
I know that sounds dramatic. But by the time you finish reading this, I think you’ll see it differently. Because the truth is that sugar isn’t just fattening, it’s actually toxic to your brain. Obesity can shrink your brain at any age. And the new class of weight-loss drugs everyone is talking about may be doing something in the brain that goes well beyond the number on the scale.
Let me walk you through what actually happens when you eat.
The Sugar Spike and the Crash That Follows
When you eat sugar, your blood glucose rises. Your pancreas responds by releasing insulin, a hormone that works like a key, unlocking your cells so glucose can get inside and be turned into energy.
The type of food matters enormously here. Complex carbohydrates like fruits and vegetables cause a slow, gentle rise in blood sugar. But a donut or a bowl of ice cream causes a sharp spike, which triggers a flood of insulin. That surge of insulin then pushes your blood sugar too low, and that crash is what leaves you hungry and craving sugar again an hour later.
Repeat that cycle day after day, and it often leads somewhere you don’t want to go: diabetes and obesity.
Three Ways This Cycle Quietly Damages Your Health
Over time, this pattern of sugar spikes and insulin surges causes three deeper problems.
First, your cells can become resistant to insulin. Sugar starts building up in your blood instead of getting inside your cells where it belongs. This is called insulin resistance, and it’s an early step toward metabolic syndrome and diabetes.
Second, excess sugar binds to proteins throughout your body in a process called glycation. Too much glycation impairs how those proteins function. This is part of why patients with poorly controlled diabetes can lose sensation in their toes, lose their vision, or damage their kidneys to the point of needing dialysis.
Third, high sugar levels generate free radicals and inflammation everywhere — throughout your body and inside your brain.
Why Sugar Is Toxic to Your Brain
This is where it gets personal for me as a neurologist.
In animal studies, high sugar levels reduce the number of dendrites, the branches on your neurons that receive connections from other neurons. Fewer connections mean less communication between brain cells, and that shows up in real life as brain fog and memory loss.
A high-sugar diet also reduces neurogenesis, the birth of new neurons in your hippocampus, which is your brain’s memory center. In other words, sugar makes it harder for your brain to build the very cells you rely on to learn and remember.
And in human studies, obesity is consistently linked to a smaller hippocampus and a higher risk of disease.
Brain Shrinkage Happens at Every Age
Here’s what surprises most people: this isn’t just a concern for older adults.
Brain atrophy linked to excess body fat shows up across every age group. Even children are not spared. When obesity affects a young brain, some of the academic struggles we see in kids may actually be tied to changes in the hippocampus and other brain regions.
There’s also a circulation piece to this story. In people with multiple risk factors, researchers have found lower blood flow throughout the brain, along with lower scores on memory and other brain functions. Less fuel reaching the brain means less capacity to think, focus, and remember.
Why We Eat and Why Willpower Isn’t the Whole Story
So why do we eat in the first place, and what actually controls our eating behavior?
Part of the answer is hormonal. Chemicals in your blood, leptin, insulin, and others, tell your brain when to stop eating, while ghrelin, the “hunger hormone,” tells your brain to eat more.
But eating isn’t only about hunger. Your brain’s reward system, the same circuitry involved in addiction, lights up when you eat, and especially when you eat sugar. Over time, this creates craving and tolerance. You crave sugar constantly, and you need more of it to feel the same satisfaction you once got from less.
Your prefrontal cortex is supposed to act as the brake on all of this, the part of your brain that helps you stop after the first bite. But in obesity, the prefrontal cortex doesn’t work as well, and your willpower around food shrinks along with it.
I want to be clear about what this means: eating too much is not simply a lack of discipline. For many people, it reflects a genuine addiction to food. That’s not an excuse; it’s a starting point for real solutions.
Where Ozempic Fits In
This brings us to the newest piece of the puzzle.
Medications like Ozempic work in three places at once. In the pancreas, they increase insulin and lower a hormone called glucagon. In the stomach, they slow digestion so you feel full faster and for longer. And in the brain, they reduce appetite directly, quieting the cravings that drive addictive eating.
Many patients on these drugs describe something fascinating: a quieting of what’s been called “food noise,” the constant mental chatter about food that runs in the background all day. Researchers are now studying whether these same medications might help with Alzheimer’s prevention, and even with addiction to alcohol, smoking, or other behaviors, since they appear to turn down the brain’s reward and addictive pathways.
But turning down the reward system isn’t free of trade-offs. Some patients report depression, fatigue, or even brain fog. This is still very much an active area of research, and I’ll be watching it closely.
What I Want You to Remember
Your brain is not separate from the food you eat. Every sugar spike and every extra pound leaves a mark on every organ in your body and on your brain.
If you want to stay sharp, the path is clear. Eat healthy food in reasonable portions. Exercise often. When you are fit, your brain simply works better.
People have known the essence of this for centuries: healthy body, healthy mind. What’s different now is that, for the first time, we have the scientific data to understand exactly how it works and how you can use that knowledge to take back control of your eating and protect your brain for decades to come.

Why Exercise Is the Most Important Pillar of Brain Health
I want to talk to you about the single most important thing you can do for your brain.
In my work as a neurologist, I describe five pillars of brain health: fitness, sleep, nutrition, mindset, and brain training. Each of them matters. Each of them, done well, makes your brain measurably stronger. But they are not equal, and by far the most important pillar of brain health is exercise and fitness.
I know that “exercise is good for you” sounds like advice you have heard a thousand times. What most people have never heard is why, what actually happens inside your brain and your cells when you move your body. Once you understand the biology, exercise stops being a chore on your to-do list and becomes more like a superpower.
Let me walk you through it.
Tiny Factories Power Your Cells, and You Can Build More of Them
Inside every one of your cells are small structures called mitochondria. Think of them as tiny factories that generate ATP, the energy currency of your body. Everything you do requires ATP. Your brain runs on it. So does your heart, your kidneys, your muscles, your skin. Nothing in your body works without the energy these little factories produce.
Here is the part that should concern you: with aging, both the number and the function of your mitochondria decline with every decade of life. It is one of the quiet engines of aging, operating silently in the background, long before you feel any difference.
And here is the part that should excite you: exercise reverses that decline.
When you exercise, you increase the number of mitochondria inside your cells. More factories. More energy. More capacity in every organ of your body, including your brain. If you want to rejuvenate every cell in your body at the most fundamental level, this is how you do it. And the best way to build more mitochondria is to build your fitness stamina.
More Blood Vessels, More Oxygen, More Nutrition
The second thing exercise does is expand your brain’s supply lines.
Physical activity increases the number of capillaries, the small blood vessels that deliver blood throughout your brain, your retina, your skin, and every other organ. More vessels mean more blood flow. More blood flow means more oxygen and more nutrition reaching every cell in your body.
Your brain is one of the most metabolically demanding organs you have. It depends, moment to moment, on a rich and steady supply of oxygen and nutrients. When you exercise regularly, you are literally upgrading the infrastructure that feeds it.
Exercise Grows the Part of Your Brain That Remembers
The third effect is, to me, the most remarkable of all.
Deep inside your temporal lobe sits a structure roughly the size of your thumb called the hippocampus. It is the ground zero for learning and memory in your brain. And when you exercise, you increase the number of neurons and synapses inside your hippocampus.
Let that sink in. Physical movement, walking, swimming, dancing, and playing tennis, causes new brain cells and new connections to form in the exact region that determines how well you learn and remember.
The downstream benefits are exactly what you would expect. People who exercise have a larger hippocampus and a larger cortex. They have better memory. They sleep better and enjoy a better mood. They are far less likely to develop Alzheimer’s disease decades later and less likely to suffer heart attacks and strokes along the way.
There are very few things in medicine I would call a no-brainer. Exercise is one of them.
The One Number That Predicts Your Brain’s Future
So what does it actually mean to be “fit”?
Fitness means stamina and endurance. How many flights of stairs can you climb? How far can you walk without stopping? These everyday questions point to something we can measure precisely, a number called VO2 max.
VO2 max is the total amount of oxygen your body can consume at peak exercise, usually measured in milliliters of oxygen per minute per kilogram of body weight. It is the gold-standard measure of cardiovascular fitness and endurance.
And it turns out to be far more than a fitness statistic. People with a higher VO2 max have more mitochondria in their cells, a bigger hippocampus, and a far lower likelihood of developing Alzheimer’s disease. It is a remarkable measurement, a single number that can tell you, today, what is likely to happen to your brain in the future.
You can measure your VO2 max precisely at a gym or a doctor’s office. But there are also simple ways to estimate it: walk one or two miles, then record your time, your heart rate, and your weight, and calculate your approximate VO2 max. I strongly recommend that you measure it and use that number as your baseline. What gets measured gets improved.
How to Build Your Fitness: The Right Way
If you have not been active, the path forward is simpler than you think. Here is what I tell my patients:
Start slowly. Do not go from nothing to a lot in one week. Begin with walking, and increase the amount of exercise you do on a weekly basis. Gradual, consistent progress is what builds mitochondria and what prevents injury and burnout.
Be persistent and win the first step. Some mornings, you will wake up and not feel like going for a walk. Do not negotiate with that feeling. Just get up and go. Once you have put your shoes on and stepped outside, the rest is easy. The first step is the difficult part; everything after it takes care of itself.
Find the exercise you actually like. If you don’t enjoy the gym, don’t go to the gym, go for a walk. If you don’t like running, play tennis. If you don’t like tennis, take dancing lessons. Do something you genuinely enjoy, because the best exercise is the one you will still be doing three months from now. Remember: the more active you are, the more mitochondria you generate.
My Prescription
Exercise is the most important thing you can do for your brain, and you need to do it every day.
My recommendation is simple: remain active every single day. Walk 5,000 steps or more as much as you can. Get at least three hours of real exercise each week, and make sure it is something you enjoy.
Do this consistently, and you will be doing the best possible service for your brain and your body. You will live longer. And you will stay sharp well into your 80s and 90s.

How to Become a Brain SuperAger
Our understanding of what happens to the brain has changed completely in the past five to ten years. We are living through a major paradigm shift in how we view aging — and what we believe happens to the brain as we grow older.
The popular belief is that once you hit midlife, your memory fades, your thinking slows, and there is nothing you can do about it. Recent scientific discoveries, including my own research publications, tell a very different story.
I am a neurologist and a professor at Johns Hopkins with four decades of clinical and research experience in memory and Alzheimer’s disease. I want to introduce you to one of the most exciting concepts in modern medicine: becoming a Brain SuperAger.
What is a Brain SuperAger?
A Brain SuperAger is someone in their 80s or 90s who performs like a person 20 or 30 years younger.
My own grandmother was one. Even at 90, she loved volunteering in her community, joining her prayer groups, and reading books. She was vibrant and full of life until her very last days.
SuperAgers like my grandmother are not born special. Every day, they make choices that keep their brains healthy — and you can make those same choices, too. A person who exercises regularly, eats well, sleeps well, manages stress, and smiles often can remain strong and functional well into old age. Give your brain the right conditions, and it will thrive and grow. It will keep you sharp and vibrant for life. Neglect it, and it will shrink — bringing memory loss, confusion, and dementia.
The 10 ways we quietly shrink our brains
These are the most important ways we neglect the brain and cause it to shrink. Each one does its damage silently, in midlife, long before any symptoms appear.
- Chronic stress. Elevated cortisol damages the hippocampus, the thumb-sized region critical for learning and memory. The more years of chronic stress, the more the hippocampus shrinks.
- Poor diet. Highly processed foods and foods high in sugar impair brain function at a cellular level.
- Sedentary lifestyle. Physical inactivity reduces blood flow to the brain and lets brain cells shrink and fade.
- Poor sleep. During sleep, the brain literally cleans itself. Without it, toxic proteins such as amyloid accumulate and form plaques.
- Social isolation. Loneliness is one of the most powerful predictors of cognitive decline.
- Untreated depression or anxiety. These are not only mood disorders — over time, they physically shrink the brain.
- Uncontrolled high blood pressure. Vascular damage quietly erodes brain tissue for years before any symptoms appear.
- Obesity and metabolic syndrome. Insulin resistance in the brain is a key driver of memory loss and cognitive decline.
- Hearing and vision loss. When the brain stops receiving adequate sensory input, it begins to shrink.
- Low cognitive engagement. A brain that is not challenged is a brain that is not growing.
The good news is that every one of these factors can be addressed — often without medication — through better lifestyle choices. People who care for their brain every day, the same way they care for their skin, really do become SuperAgers.
What decades of research reveal
Researchers at Northwestern, Rush, Harvard, Johns Hopkins, and many other leading institutions have spent decades studying SuperAgers — people in their 80s who stay sharp and independent. What they found is remarkable.
These individuals carry no special genes. They have no special features. They have not discovered a secret supplement or a magic intervention. What they share is a pattern of healthy, consistent lifestyle habits maintained over decades. They exercise and stay active. They keep strong social connections. They sleep well. They eat diets rich in vegetables, healthy fats, and lean proteins. They keep learning — an instrument, a language, a curiosity about the world. Their brain MRIs show less atrophy and larger hippocampal volume than their peers. This is not anecdote. It is what science consistently shows across decades of research at the world’s leading universities.
Change how you think about aging
The most important step toward becoming a SuperAger is to change how you think about aging and the brain.
There is a deeply harmful narrative in our culture that cognitive decline is inevitable — that it simply happens, and nothing can be done. I have spent 40 years watching patients internalize that story and then unconsciously live it out. Do not accept that narrative.
If you are in your 50s, 60s, or 70s and feel you are not as sharp as you were a decade ago, that feeling is a signal, not a verdict. It is your brain telling you that something on the list of 10 factors needs attention. Go through them one by one and ask yourself honestly: Am I sleeping enough? Am I moving enough? Am I under chronic stress? Am I socially connected? Am I eating in a way that serves my brain?
Then begin to address whatever you find — on your own, with the guidance of my book The Invincible Brain, or with a health professional. Address those issues, and you will see a difference in your thinking within weeks. Your brain is far more adaptable than you believe. Neuroplasticity does not stop at 60 or 70; the capacity to grow, heal, and sharpen is present throughout your lifespan.
The 5 Pillars of Brain Health
Most of what I have described comes down to five pillars — the foundations of becoming a SuperAger.
- Regular exercise. Just 30 minutes of walking, five days a week, increases the size of your hippocampus and boosts BDNF, the brain’s growth hormone.
- Brain-healthy nutrition. A Mediterranean-style diet rich in olive oil, fish, leafy greens, nuts, and berries has been shown in multiple large studies to lower the risk of Alzheimer’s and slow cognitive decline.
- Optimal sleep. Seven to eight hours of quality sleep each night lets the brain flush out toxic proteins. Sleep is not passive — it is active brain maintenance.
- Stress reduction. Chronic stress is one of the fastest ways to age the brain. Mindfulness, social connection, time in nature, and regular exercise all protect and nourish it.
- Cognitive engagement. Challenging the brain with novel, complex activities — a new skill, a hard problem, structured brain training — builds cognitive reserve and expands resilience.
These pillars work together. Strengthen one, and you tend to strengthen the others, and the cumulative effect over time is profound.
Becoming a SuperAger is not about perfection. It is about awareness, intention, and consistency. Your brain responds to how you treat it, and the choices you make today are quietly shaping the brain you will live with tomorrow. You do not have to accept cognitive decline as your destiny. You can aim, instead, to become a Brain SuperAger.

How Your Brain Rewires Itself to Make You More Intelligent
By Dr. Majid Fotuhi, MD, PhD
Right now, while you’re reading this, something extraordinary is happening inside your head.
Each of the billions of neurons in your brain is connected to thousands of other neurons through contact points called synapses. As you pay attention to these words, your neurons are strengthening some of those synaptic connections and building new ones. New proteins are arriving and getting installed in the branches of your neurons. New synapses are being formed and remodeled in real time with no conscious effort from you whatsoever.
This process is called neuroplasticity. And once you truly understand it, it has the potential to change the way you see yourself — and what you believe you’re capable of.
Your Brain Is Not Fixed
For most of human history, scientists believed that the brain was essentially a static organ. You were born with a certain number of brain cells, and once adulthood arrived, the structure of your brain was largely set. Learning was possible, of course, but the underlying hardware was thought to be fixed.
We now know this is wrong.
Your brain is a living, dynamic, constantly changing structure. Every time you practice a new skill, neurons build new connections between different areas of your brain. The more you practice, the more those connections are refined and strengthened. Over time, what was once effortful becomes automatic — not because your personality or willpower changed, but because the physical architecture of your brain changed.
The more roads your brain builds, the faster and more efficiently information moves between different regions. And the result of that expanded network is something we call intelligence.
Intelligence Is Something You Build
This is one of the most important insights I’ve shared in my 35 years of studying the brain. Intelligence is not a fixed quantity you’re born with. It is the result of new synaptic connections forming between neurons.
Think of your brain like a city. When a city builds new streets, new highways, and upgrades its existing roads, communication between neighborhoods becomes faster and more efficient. Commerce increases. Ideas move more quickly. The city becomes more capable.
Your brain works the same way. Every new skill you practice, every subject you study, every challenge you push through, these experiences are literally building new roads inside your head. And those roads make you more intelligent.
This is not a metaphor. It is neuroscience.
What the Research Shows
The evidence for neuroplasticity is extensive and growing more robust with each decade of research.
One of the most cited studies examined London taxi drivers, who are required to memorize thousands of city streets before they can be licensed. Researchers found that these drivers had a measurably larger hippocampus — the brain region most critical for memory and spatial navigation — than non-drivers. The more years they had been driving, the more pronounced the difference.
Medical students provide another compelling example. Studies have shown that students who study intensively for three months in preparation for qualifying exams demonstrate measurable growth in hippocampal volume over that short window. When they stop studying after the exam, the growth levels off. The brain responds directly to the demands we place on it.
Musicians who begin practicing in childhood develop thicker connections between their left and right brain hemispheres than non-musicians. People who become fluent in a second language develop a more robust network of synaptic connections throughout the brain — and that additional cognitive reserve appears to protect them against cognitive decline decades later. Athletes who practice their sport extensively develop more elaborate and efficient neural networks for processing movement and spatial information.
Practice does not just build skills. It builds brains.
My Own Experience With Neuroplasticity
I did not always believe this about intelligence. Not because I hadn’t read the research, but because I hadn’t yet applied it to myself.
When I came to America in 1987, I had been accepted to Johns Hopkins for a doctoral degree in neuroscience. I should have been excited. Instead, I was frightened. I was trying to improve my English, adapt to an entirely new culture, and keep pace intellectually with some of the sharpest students in the country.
I remember sitting in an advanced neuroscience seminar, struggling to follow every word, and thinking: how on earth am I going to pass my qualifying exams?
I could not have imagined, sitting in that lecture hall, that I would one day become a neurologist and professor at the very institution that was intimidating me. I could not have imagined writing four books about the brain, one of which would become a USA TODAY bestseller.
The more I studied neuroplasticity, the more my confidence grew. The science showed me, again and again, that we all have the capacity to grow our brain — at any age, in any field. I had been underestimating my own neurons. And I had been wrong to do so.
What This Means for You
The most important thing I want you to take from this is simple: your brain has no limit for learning.
It does not matter how old you are. It does not matter how you performed in school. It does not matter whether you think of yourself as “a smart person” or not. These assessments were formed before you understood what your brain is actually capable of.
Every person who has ever mastered a new skill — learning a second language, becoming an exceptional athlete, developing expertise in a field they knew nothing about — started exactly where you are right now. Their brain was not different from yours. They simply gave their neurons the opportunity to build new roads and new connections. And those connections changed everything.
Your neurons know how to find each other. They know how to form new synapses. You do not need to teach them. You do not need to oversee the construction process. You just need to give them something worth building — and the patience to keep practicing.
Neuroplasticity does not stop at 25, or 40, or 60, or 80. It continues across your entire lifespan. I have seen it in my patients. I have seen it in my research. And I have lived it myself.
Every time you choose curiosity over comfort, every time you push yourself to learn something new, your neurons are reaching out and finding each other. Your brain is always waiting for you to give it that something new that’s worth building.
You really can become more intelligent — in any field you choose, at any age. The biology is on your side.

You Can Get Smarter. Neuroscience Proves It.
I want to start with something I hear almost every week, from patients, from students, from some of the most accomplished people I know.
“I’m just not as smart as other people.”
Sometimes it comes out directly, like that. More often it arrives dressed in other language. Someone describes a co-worker who always has the answer in the meeting. A sibling who seems to grasp ideas without effort. A friend who navigates social situations with a ease they can’t replicate. And beneath all of it, the same quiet conclusion: some people are just built differently. Some people got more of whatever “it” is.
Once, a teenage patient came to see me with her mother because she felt she would never be as smart as her older sister. She was getting A’s in every subject except math and physics. She loved drawing, writing, singing, and acting — she was the star of her school’s theater group — but in her mind, none of that counted. She couldn’t understand the equations. And in her world, that meant she wasn’t smart.
I want to tell you what I told her. And I want to explain the neuroscience behind it, because this is not a motivational speech. This is biology.
What Intelligence Actually Is
When we talk about the brain and higher-level thinking, we often confuse three words that mean very different things: cognitive skills, talents, and intelligence.
Cognitive skills are the higher brain functions you use every day — reading, writing, navigating a conversation, doing your taxes, following a recipe. Talents are cognitive skills that go one step further: playing a musical instrument, excelling at a sport, writing beautifully, creating visual art. And intelligence simply means doing any of these cognitive skills at an exceptionally high level.
Here is what neuroscience tells us about all three: they are the result of networks of neurons connecting and firing in two parts of your brain — the cortex and the hippocampus. The cortex is the outer layer of your brain, and the hippocampus is an extension of the cortex that sits deep inside your temporal lobe, roughly the size of your thumb. Together, they form the biological foundation for everything you think, learn, and remember.
And what is the most important thing I can tell you about those structures?
They are highly malleable. They can change. They change for the better every single time you use them. When you challenge them by doing something difficult — something genuinely unfamiliar and demanding — you make them grow larger and stronger. They are, in the most literal neurological sense, like your muscles. The more you challenge them, the larger and stronger they get.
There Are 30 Forms of Intelligence — Not Two
In my book, The Invincible Brain, I describe 30 different forms of intelligence. Not two. Not the handful that get tested on standardized exams. Thirty.
There is emotional intelligence — your ability to perceive and manage feelings in yourself and others. Social intelligence — your ability to connect with almost anyone in any room. There is body movement and dexterity intelligence. Musical intelligence. Cooking intelligence. Humor intelligence — yes, being a genuinely funny person is a form of intelligence, and a sophisticated one at that. There is navigational intelligence, digital intelligence, street-smart intelligence, happiness intelligence, and many more.
My point is not simply that the definition of intelligence is broader than we thought. My point is that the way we have been measuring and talking about intelligence — in schools, in workplaces, in the way we size each other up — has been systematically wrong. We have taken two or three narrow cognitive domains, elevated them above everything else, and allowed millions of people to walk away from childhood and adolescence believing they came up short.
My teenage patient had extraordinary intelligence for visual art, narrative writing, performance, and musical expression. Her cortex and hippocampus had grown and specialized to be exceptional in those areas. They had not, yet, been challenged enough in math and physics. But that was not a fixed condition. It was a starting point.
The Patient Who Scored in the 99th Percentile
After I explained to her the malleability of the cortex and hippocampus — that these structures change every time they are challenged, and that she could genuinely become excellent at math and physics if she committed to challenging them — something shifted.
She had been telling herself a story. A story that said: I am not the kind of person who is good at this. That story was not just discouraging. At a neurological level, it was an active obstacle, because it was removing the effort and practice that growth requires. Once she stopped believing the ceiling was fixed, she began working as though it wasn’t.
With some tutoring support and consistent daily practice, she improved steadily. And when she sat for her SAT exam, she scored in the 99th percentile — meaning she had performed exceptionally well across every dimension of that test, including the mathematical sections she had once believed were beyond her.
She had not discovered hidden talent she never knew was there. She had built it. That is what the brain does when you give it the right conditions.
Intelligence Is Not Fixed
I want to be as clear as possible on this point, because it runs counter to a very deep cultural assumption: intelligence is not fixed. Not at 16, not at 45, not at 70.
Every part of your cortex and hippocampus can grow stronger with practice. The science is unambiguous on this. The more you use your brain — the more you engage it in genuinely challenging, unfamiliar work — the more those neuronal networks consolidate and expand. You can acquire any talent you wish to have. There is no ceiling imposed by biology. The only ceiling that is real is the one built from a belief that the ceiling is real.
We should never tell our children they are not good at something. And we should stop telling ourselves that, too.
Five Steps to Become One Notch Smarter in Three Months
I want to give you something concrete. Not a philosophy — a method. Five steps that, practiced with genuine commitment over ninety days, will make you measurably better in any field you choose. Not the best in the world. One notch better than you are today. Which is all it ever takes.
Step 1: Shift the narrative in your head. You have to genuinely believe — not just tell yourself — that you can get better at almost anything. Because you can. The science is on your side. Every story you carry about what you’re “just not good at” is a story about where you haven’t practiced yet, not about what your brain is capable of.
Step 2: Make a list. Write down the things you would love to be good at. Dancing. Chess. Math. Cooking. Public speaking. Remembering names. Learning a language. Whatever genuinely excites you — not what impresses other people. Just make your list and be honest about it.
Step 3: Choose one. From that list, identify the one skill or hobby that would bring the most joy to your life if you became genuinely good at it. The one you feel most passionate about. Decide on that single thing. Focus matters here — the brain builds its networks through repetition of a specific demand, not through scattered effort across a dozen things simultaneously.
Step 4: Practice it every day — even for a few minutes. Take a class. Watch a YouTube series. Find a mentor. But whatever you do, touch it daily. You don’t need hours. You don’t need a perfect structure. You need to challenge that specific part of your cortex and hippocampus consistently enough that those neuronal networks have a reason to consolidate. Your only goal is to be slightly better than you were yesterday.
Step 5: Be persistent — and be proud of your mistakes. This step matters more than any of the others. Three months of consistent practice, even modest practice, will produce measurable change in the brain. That is not a promise — that is what the MRI shows. But persistence is the prerequisite.
And here is something I want you to hold onto: every time you make a mistake in the process of learning something difficult, you are among the rare few who had the courage to step outside their comfort zone. Most people don’t do that. Most people stay comfortable and tell themselves they’re not as capable as others. You’re different. Give yourself credit for that.
What 40 Years of Studying the Brain Has Taught Me
I have spent nearly four decades studying the brain, mostly at Johns Hopkins and Harvard Medical School. I have treated thousands of patients across a very wide range of cognitive conditions — from children with attention challenges to adults in the early stages of Alzheimer’s. And the one thing I know with certainty, after all of that research and all of those patients, is this:
Your brain has far more capacity than you have ever used. It is far more intelligent than you think it is.
Every day you choose to challenge it — in any domain, at any level — you are making that foundation larger and stronger. And every day you tell yourself the story that you’ve already reached your ceiling, you are choosing not to.
Start today. Just one notch. Just try to be slightly better at one thing than you were yesterday.
In three months, you will be much, much better than you are today.

Don't Let Artificial Intelligence Steal Your Intelligence
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.

Your Brain on Alcohol: How Much is Too Much?
If you’ve kept up with your readings – meaning our blogs – you’ll recognize the term “brain shrinkers.” However, if you’re new to our posts and thus have no clue what a brain shrinker is, no worries, I’ll give you the gist. Brain shrinkers – what I’ll refer to as “shrinkers” moving forward – consist of anything that cause your brain to shrink over time. This includes psychological disorders such as depression and anxiety, chronic stress, lifestyle habits such as poor diet choices, lack of physical activity, drug and alcohol abuse, insomnia, so on and so forth. And while I could spend this time discussing why and how each shrinker damages your beautiful brain, I’m not going to do that. Instead, we’re going to talk about the one shrinker that’s most intoxicating. You know the one – booze.
Before you fall down the proverbial rabbit hole and start worrying that I’m going to tell you to stop drinking altogether, wait to hear what I have to say. Frankly, I don’t care about the single glass of wine that you have with dinner a few times a week. Even moderate alcohol consumption, defined by the Center for Disease Control (CDC) as one to two drinks (which can be one or two of a) 12 oz. beer with 5% alcohol; b) 8 oz. malt liquor with 7% alcohol; c) 5 oz. wine with 12% alcohol; d) 1.5 oz. of 80-proof with 40% alcohol) per evening is not cause for serious concern, although some research has shown that it can increase a woman’s likelihood of developing breast cancer by 0.55% over the course of her lifetime. What I’m most concerned about, however, is a pattern of heavy alcohol use. No, that one night two weeks ago when you drank five or more alcoholic beverages on a single occasion (i.e., binge drinking) does not qualify. However, if you’re a man consuming 15 or more drinks in a week, or a woman consuming eight or more drinks in a week, that’s cause for concern.
Your Body on Alcohol
So, what happens when you drink? Well, as you down your first beer, that liquid gold is absorbed through your stomach lining into your bloodstream, followed by diffusion into your body’s tissues. After 20 minutes, your liver starts to metabolize the alcohol; one ounce every hour. So, if you drink until your blood alcohol content (BAC) reaches the legal limit (0.08), it’ll take about five and a half hours to leave your body. While the amount of time it takes to expel the alcohol from your system does not vary widely from person to person, several factors do effect BAC and the amount of time it takes to reach the legal limit.
Factors that affect absorption and tolerance:
Biological Sex: Dehydrogenase, the enzyme that breaks down alcohol in your tummy, is lower in women than in men. So, if Jill and her buddy Joe drink the same amount in the same amount of time, Jill will have a higher BAC.

Hormones: They impact your body’s ability to process alcohol. Drinking the same amount of alcohol during menstruation will result in higher BAC.
Body Fat/Weight: Women usually have greater percentages of body fat and lower percentages of water compared to their male counterparts. So, even if Ann and Dave weigh the same, Ann will likely achieve a higher BAC at a faster rate.
Your Brain on Alcohol
It takes roughly five minutes for alcohol to reach your brain and 10 minutes for you to notice behavioral/emotional changes. You know that feeling of euphoria that you get within several minutes of starting to drink? Yeah, that’s normal, it happens during the early stages. Subsequent stages of alcohol consumption include depression and disorientation (0.05 BAC), excitement (0.09-0.25), and confusion (0.18-0.3), to name a few; increase in BAC gives rise to new feelings and behaviors.
As I’m sure you know, drinking impacts several regions of the brain. When you’ve reached the “excitement” stage and are experiencing slurred speech, blurred vision, feelings of impulsivity, and loss of fine motor skills, that’s a result of your frontal, occipital, temporal, and parietal lobes being affected. If we’re being technical, what’s really happening is alteration of neuron membranes, enzymes, ion channels, and receptors. What’s important for you to know is that moderate drinking and rare binges won’t have any long-term effects on your brain. As Dr. Fotuhi states in his book “Boost Your Brain,” “drink no alcohol and your brain will experience the usual degradation that happens with age; drink some and you’ll see reduced damage; drink too much and injury to the brain shoots through the roof.”

That brings me to the topic of long-term brain damage. As I’m sure you’ve heard before, alcohol abuse kills brain cells. The areas impacted the most include your cerebellum, cortex, and hippocampus, the areas responsible for hand-eye coordination, balance, decision-making, and general task and cognitive performance. Abuse of alcohol also damages myelin (i.e., the protective coat around the axon of the neuron; the highway that enables chemical messages to get from one neuron to another), which results in severe nerve damage. Some alcoholics may even develop a disorder called Wernicke-Korsakoff syndrome, a disease that causes vision, coordination, walking, memory, and learning impairments.
Reminders:
–You can drink, just don’t overdo it. One glass of wine with dinner won’t do you any harm, but if you’re a male having more than 15 drinks within a week, or a female having more than eight drinks within a week, that’s way too much.
–Be nice to your liver. Remember, the liver starts to metabolize drinks after one hour. If you drink until your BAC reaches the legal limit, it’ll take around five and a half hours to completely expel it from your body.
–Different factors affect BAC. If you’re a female and you’re drinking with your male friend, remember that you will achieve a higher BAC in a shorter amount of time – blame higher percentage of body fat, hormones, and dehydrogenase levels!
-You drink too much, but you don’t know what your next step should be. Contact the National Drug and Alcohol Treatment Referral Routing Service, available at 1-800-662-HELP. You’re not alone. Don’t be afraid to ask for help.

Alcohol’s Effect on Brain and Behavior
Factors that Affect How Alcohol is Absorbed and Metabolized
Your Brain on Stress
Stress levels are on the rise in America. While stress affects your day-to-day quality of life, it can also create a host of health conditions and impact your brain both structurally and functionally. In order to prevent this damage, it is important to understand the connection between your brain and stress. what stress is actually doing to your brain.
When you experience stress, the brain triggers the release of a hormone called cortisol into your bloodstream. Small amounts of cortisol can help you focus and take action in a high pressure situation; for example, you can function better when you sit down to take a test or when you meet a not-so-friendly bear on your camping trip. However, too much cortisol can shrink the brain, damage your memory capacity, and impair communication between different regions of the brain.
Damage to Memory
In a particularly stressful time of life, you may have more trouble remembering your doctor’s appointment or where you left your car keys. This is because stress directly impacts short term memory and can inhibit your ability to make long term memories. Studies show that even mild exposures to stress before a memory retention test result in worse scores. Research also shows that individuals with higher levels of cortisol had smaller hippocampi – the region of your brain that is critical for learning and memory. This is because stress can kill brain cells and make it harder for new neurons to survive. If you have fewer neurons in your hippocampus, your memory function will decline and over time you will have a higher risk for developing Alzheimer’s disease. Too much stress can erase the benefits of lifestyle factors that have been shown to be helpful for better cognitive performance and longevity (factors such as eating healthier, exercising, learning new skills, and sleeping well).
Damage to Executive Function
Not only does stress make it harder for you to remember the name of the coworker you just met, researchers found that individuals who experience chronic stress, have less gray matter (or brain volume) in their prefrontal cortexes. This region of the brain right behind your eyes is important for tasks such as planning, decision making, problem solving, self-control, and emotion regulation. This could explain why you experience more frequent mood swings, or why making a simple decision may feel more difficult during periods of high stress.
Damage to Communication
High levels of cortisol in the bloodstream, especially for long periods of time, can shrink and impair several areas of the brain. But stress can also change how the different brain regions communicate with each other. New research has found that chronic stress can result in the abnormal overproduction of myelin; a fatty substance that helps speed up the transmission of electrical signals between neurons.
Too much myelin can disrupt the brain’s sensitive balance of communication. Studies found that in people who developed PTSD, excess cortisol from stressful experiences led to an excess of myelin. The excess production of myelin may have strengthened the connection between the part of the brain responsible for learning and memory (the hippocampus) and the part responsible for fight-or-flight responses (the amygdala). A faster connection between these two areas can result in stronger fear responses to a given situation. These findings suggest that increased cortisol may make it more likely for someone to develop depression, PTSD, or other mental disorders because the excess myelin disrupted the brain’s normal communication patterns. This new area of neuroscience research suggests that when it comes to the brain, too much of a good thing – high levels of myelin and stronger connections — can potentially do more harm than good.
While reading this article, you may have felt your own stress levels rise as you learned about the negative impacts of stress. However, because of something called neuroplasticity, the brain has an incredible capacity to bounce back and repair itself. Introducing a few routines in your day-to-day life such as meditation, exercise, and getting the proper amount of sleep can significantly reduce your cortisol levels and protect your brain from the effects of stress. The good news is that a just few simple practices can significantly boost the level of neuroplasticity in your brain and make you feel calmer and happier.

Social Media and Eating Disorders: What's the Connection?
Social media has changed the way we connect with each other and the ways we think about ourselves. The number of people using these platforms skyrocketed in recent years and society is only just beginning to understand its negative effect on body image. While there is no single cause of eating disorders, researchers have found strong links between social media use and the development of eating disorders.
Eating disorders are a major public health issue and can cause serious long-term health problems including heart failure, neurological damage, and gastroparesis. Sadly, data shows that the number of eating disorders cases is on the rise, especially among adolescents. 69% of children now have their own smartphones by the age of 12, and 72% of teens now use social media daily. Only recently have studies begun to examine how those platforms impact an individual’s self-concept.
Since human beings are inherently social creatures, the lure of social media is clear. While these platforms offer many opportunities for new connections and interactions, they also allows for rampant social comparison. Popular culture promotes a particular type of appearance as “ideal”, which currently centers around thinness. Before social media, people may have seen this standard on TV or in magazines, but now they have the opportunity to actively engage with it in a social context.
Social media has a highly interactive format and encourages connection, not only with friends and peers, but also to various celebrities, models, and brands. It feels far more personal and offers the illusion that the user is less emotionally separated from the people they admire or aspire to emulate. Thus, these platforms have potential to create a deeper emotional impact on their users than they may be aware of.
While there are many positive aspects to these platforms, there is also a potential for significant damage. With its interactive format, social media offers a constant and active space to engage in social comparison. With photo and video editing features, beauty standards become increasingly unrealistic and can easily lead to severe body dissatisfaction. Young people, women especially, have been found to be particularly vulnerable to the effects of social media.
Teens, “tweens” (children aged 8-12), and young adults are in a time characterized by many bodily and developmental changes, all while attempting to figure out who they are. In this stage, they are wired to be more absorbed in their social relationships and they are more likely to internalize feedback they get from their surroundings as they attempt to form their own identity. Additionally, the parts of the brain responsible for reasoning and decision-making are not yet fully developed, which can increase the risk for confusing the perfectly edited photos or videos on social media for actual reality. Not only do these combined factors increase the risk for negative body image, but also the risk of developing anxiety and depression.
When examining this phenomenon, one study found that having even just one social media account was associated with greater thin ideal int
ernalization, body surveillance, and drive for thinness in a large sample of adolescent girls. Additionally, higher numbers of friends or followers and more time spent on social media platforms was correlated with higher level of body dissatisfaction. Other studies found that those who used social media consistently were more likely to have negative body image and engage in disordered eating behaviors such as food restriction and compulsive exercise. Overall, research has consistently shown that there is a strong connection between developing an eating disorder and social media use.
While there are multiple factors that determine whether an individual develops an eating disorder, research shows that use of social media increases the risk, especially in adolescents. This does not mean that you should never use social media. However, it does mean that you should be aware of how it may be affecting your own self-image and self-esteem in order to prevent this damage.
Disordered eating behaviors often go hand in hand with anxiety. If you are feeling unusually stressed out or anxious lately, check out this post to learn how neurofeedback at NeuroGrow Brain Fitness Center can help! To schedule an appointment, click here or email us at info@neurogrow.com.
