In this episode of The Diary of a CEO, featuring Dr Ann McKee and Narrator, The Brain Doctor: This Is The Fastest Way To Get Dementia & Its More Common Than You Think! explores revealed: Everyday Sports Hits That Quietly Destroy Young Athletes’ Brains Neuropathologist Dr. Ann McKee explains chronic traumatic encephalopathy (CTE), a progressive, trauma‑induced brain disease that can lead to early dementia, severe personality changes, and suicide, even in young athletes. Drawing on nearly 10,000 brain autopsies and the world’s largest CTE brain bank, she links small, repetitive head impacts in sports, military service, and domestic violence to widespread tau protein damage in the brain.
Revealed: Everyday Sports Hits That Quietly Destroy Young Athletes’ Brains
Neuropathologist Dr. Ann McKee explains chronic traumatic encephalopathy (CTE), a progressive, trauma‑induced brain disease that can lead to early dementia, severe personality changes, and suicide, even in young athletes. Drawing on nearly 10,000 brain autopsies and the world’s largest CTE brain bank, she links small, repetitive head impacts in sports, military service, and domestic violence to widespread tau protein damage in the brain.
McKee details shocking prevalence data: over 90% of studied NFL players, about 90% of college players, and 41% of contact‑sport athletes who died before 30 had CTE. Case studies such as 18‑year‑old high school player Wyatt Bramwell, college player Owen Thomas, and NFL star Aaron Hernandez show how subtle mood and behavior changes can escalate to tragedy.
She also describes fierce institutional resistance from major sports leagues, especially the NFL, which initially tried to discredit her work and later structured settlements that exclude future CTE cases. Despite slow progress, she argues the disease is largely preventable and calls for reduced head impacts, delayed full contact for youth, better education, and continuous player monitoring.
In the final section, McKee connects CTE to the broader landscape of dementia, contrasting it with Alzheimer’s and emphasizing the roles of inflammation, small vessel disease, lifestyle factors, and sleep in protecting long‑term brain health.
Key Takeaways
CTE is a distinct, trauma‑induced dementia that starts young and often goes unrecognized.
Chronic traumatic encephalopathy is caused by small, repetitive head impacts—often subconcussive blows that don’t cause obvious symptoms. ...

Repetitive head impacts in sports carry a far higher CTE risk than most people realize.
In McKee’s brain bank data, over 92–95% of examined former NFL players and about 90% of college players had CTE. ...

Early CTE symptoms are usually psychiatric and behavioral, not memory loss—so they are easily misattributed.
In young athletes, CTE commonly presents as depression, emotional volatility, irritability, impulsivity, poor judgment, aggression, and a “short fuse,” sometimes accompanied by early memory and cognitive changes. ...

Helmets prevent skull fractures, not the brain movement that drives CTE.
A helmet protects the skull bone and reduces catastrophic bleeds from fractures but cannot stop the brain from moving and stretching inside the skull during rapid acceleration and rotation. ...

CTE progression can continue even after head impacts stop, driven by inflammation and aging.
CTE severity is influenced by both years of exposure and age at death. ...

The disease is largely preventable if sports aggressively reduce head impacts, especially in youth.
McKee argues that “you cut out the hits to the head, you cut out this disease. ...

Broader brain‑health habits—vascular health, stress, sleep, and mental stimulation—modify dementia risk.
For Alzheimer’s and age‑related dementias, McKee emphasizes cardiovascular health (managing blood pressure, blood sugar, cholesterol), avoiding diabetes, limiting alcohol, and reducing chronic stress to protect small brain vessels and the blood–brain barrier. ...

Notable Quotes
“You cut out the hits to the head, you cut out this disease. It’s entirely preventable.”
— Dr. Ann McKee
“Every time you see it in a young person, you just can’t get over it. It stops you in your tracks.”
— Dr. Ann McKee
“The important hits are the hits that don’t cause symptoms, are not considered concussion.”
— Dr. Ann McKee
“Helmets protect the bone, but not the brain.”
— Dr. Ann McKee

Transcript Preview
In a study of 152 young athletes, most of them had brain damage from small, repetitive hits to the head, and it really destroys a person's life. That is shocking news, but medical professionals don't take it seriously, and the NFL wanted me to present my findings, but they didn't believe me. And so, there was a huge effort to really discredit me.
Dr. Ann McKee is the world-leading brain scientist who runs the world's biggest brain bank. She's revealing groundbreaking research on the serious life-threatening consequences of playing sport.
These injuries are acceleration/deceleration very rapidly, and twisting of the brain, and that frays the nerve cells, and then over time, the disease progresses, and this protein called tau, it stains brown, and it starts spreading through the brain. And we have lots of evidence that this is happening in contact sports, but also in military veterans, domestic violence, et cetera. And it causes depression, personality changes, aggressive and violent behaviors, or maybe the person takes their own life. Look at Aaron Hernandez and Wyatt Bramwell, 18 years old, he was an American football player, and he videotaped himself before taking his own life.
My head is pretty messed up and damaged. The voices and demons in my head just started to take over everything I wanted to do.
It was his dying wish to donate his brain.
Yeah. I saw multiple CTE lesions in many parts of his brain.
Caused by playing tackle football for several years.
Yes, and every time you see it in a young person, you just can't get over it.
It's a lot for you to carry.
There's some days that are darker than others, but we're not where I'd like us to be.
What do we do about this?
We have to-

Dr. McKee, what is the mission that you're on in, with your life and your professional endeavors?
Well, my mission in life has taken abrupt change about 17 years ago when I first saw, uh, CTE in the brain of a football player, and I realized that, uh, that the play of football was associated with, uh, a chronic and progressive neurodegenerative disease. So, my first two cases, uh, in football players were 45-year-old men, and I was stunned, uh, to see CTE in their brains, c- 45 is extremely young for a neurodegenerative disease. And then my third case was actually an 18-year-old, where I saw, uh, the beginnings of CTE in the brain of a high school player, and I've never looked back since then. Uh, i- th- when you talk to the families and you hear the tragedy that, that they experienced, the, the heartache of, of living with these people who change before their eyes, their personality changes, their mood changes, they become people they don't recognize, uh, and then they live through often a, an accidental death, or maybe the person takes their own life, and it's a result of, of almost a coincidence of seeing that, those changes in the brains of American football players, I, I immediately just wanted to eradicate this disease.
