Ancient Neurosurgery and Modern Brain Scams

A Hole Lot of Nonsense: Surgery Before Science

People once drilled holes in skulls to cure madness

And in some cases… it actually helped. Well, if you consider madness what happens if you get a stroke from too much pressure in your brain from trauma

That’s the wild part.

While visiting the Surgeons’ Hall Museum in Edinburgh, I saw ancient skulls with round holes cut into them—evidence of trepanation, one of the world’s oldest surgeries. Even more shocking? Many of those patients survived. Some healed so well that they lived for years.

But let’s back up.

What is trepanation?

It’s the act of scraping or drilling a hole in your skull. Ancient people did it across continents—from South America to Europe.

We don’t know exactly why. Some may have used it to relieve pressure after a head injury. Others might have believed it released evil spirits.

Here’s the thing: it sometimes worked.

Today, we know that pressure in the brain—from a bleed, swelling, or injury—can be deadly. Modern medicine sometimes calls for drilling a hole or even removing part of the skull to save a patient’s life.

The ancients may have stumbled onto something real. Or they may have been guessing.

That’s the danger when we mix luck with ritual. If one patient improves, people assume the treatment works—even if there’s no science behind it.

Dr. Cotton and the colon cure

Jump ahead to the 1900s.

Dr. Henry Cotton believed mental illness came from hidden infections in the body. So what did he do? He had his surgeons remove teeth, tonsils, stomachs, and colons—even when patients showed no symptoms.

Many died. Most didn’t improve.

Still, Cotton was praised in journals and trusted by major institutions. His confidence overshadowed the lack of results.

It’s a painful reminder that being sure of yourself doesn’t make you right. Sounds like modern-day influencers - confidence beyond erudition.

Today’s brain hacks: same pattern, better packaging

Right now, people are terrified of dementia. That fear fuels a massive market for brain supplements. One of the biggest sellers? Lion’s Mane mushrooms.

They’re in powders, coffees, and pricey pills. Some lab research suggests benefits, but actual human studies? Weak at best.

Meanwhile, studies show that eating a Mediterranean or MIND-style diet can reduce your risk of dementia by up to 50%. But those diets don’t come in fancy bottles.

Instead of focusing on real food, we chase the next shiny pill.

And let’s talk about PRP…

PRP stands for platelet-rich plasma. Some orthopedic surgeons spin down your blood, pull out platelets, and inject it back into sore joints. They claim it speeds healing.

The truth? There’s little evidence that PRP works for most uses. But it’s expensive. And because it sounds high-tech, people trust it.

The orthopedic surgeon gets the thousands of dollars for it because insurance won't cover it. They won't cover it because it isn't a researched treatment. But if your surgeon says here take this and you will recover faster - what to do?

I should know—I co-authored one of the first papers on PRP for diabetic wounds, where it actually showed benefit.

But that’s a far cry from injecting it into tennis elbows for cash.

We’ve upgraded the tools. Not always the thinking.

What history teaches us

When I look around this museum, the lesson is clear:

We’ve always wanted to help. But good intentions without good science can hurt people.

Real medical progress comes from questioning our own assumptions. It comes from saying, “Let’s study this,” instead of, “Let’s just try it.” Whether it’s trepanning or turmeric, we need to ask:

Does this really work—or are we just hoping it does?

>> Dr. Terry Simpson: Right now, I am standing in the Surgeons Hall Museum

Speaker:

in Edinburgh. It's one of the oldest

Speaker:

surgical museums in the world, filled with

Speaker:

skulls, saws and surgical tools that tell

Speaker:

the stories of medicine's slow,

Speaker:

stumbling progress. And today, we're going to talk about

Speaker:

one of the oldest and sometimes the most horrifying

Speaker:

ideas in medicine and surgery. That the best way to

Speaker:

treat mental illness was to drill a hole in

Speaker:

your head.

Speaker:

I'm Dr. Terry Simpson, your chief medical

Speaker:

explanationist, on site at the

Speaker:

Surgeons Hall Museum in Edinburgh.

Speaker:

And this is Fork U Fork

Speaker:

University, where we unpack the weird,

Speaker:

wild and too often wrong history

Speaker:

of food, medicine and surgery. And we look at

Speaker:

how bad ideas never really die.

Speaker:

They just rebrand.

Speaker:

Let's start today with trepanation, the

Speaker:

practice of drilling or scraping a hole in the

Speaker:

skull. It's one of the oldest known

Speaker:

surgeries in human history. And here at the

Speaker:

Surgeons Hall Museum in Edinburgh, you can

Speaker:

see the actual ancient skulls with neat

Speaker:

round holes carved into them. Some of these

Speaker:

skulls show clear signs of healing,

Speaker:

meaning the patients survived, some of them

Speaker:

for a long time. But why did they do it?

Speaker:

That's the part we don't know.

Speaker:

Maybe they did it to relieve pressure from a head injury.

Speaker:

Maybe they thought they were letting out evil spirits.

Speaker:

Maybe, just maybe, they figured out by

Speaker:

observation that people sometimes got better

Speaker:

when they drilled. Were they scientists

Speaker:

or shamans, healers or hopeful butchers?

Speaker:

Sadly, that data is lost. But we

Speaker:

do have some disturbing data today. We

Speaker:

do drill holes in the skull, but we do it for some really

Speaker:

good reasons. If someone has increased

Speaker:

intracranial pressure after trauma, meaning high

Speaker:

pressure in their brain, we drill a hole. Or

Speaker:

sometimes if they have a subdural hematoma or a brain

Speaker:

bleed, we drill a hole to remove the clot, to relieve

Speaker:

the pressure on the brain. So you don't have stroke like symptoms or

Speaker:

lose second grade. And in some severe

Speaker:

brain injuries, we even remove a portion of the

Speaker:

skull to let the brain swell without

Speaker:

compression. So trepanation as a

Speaker:

technique isn't the problem. The problem

Speaker:

was a lack of understanding about why it works sometimes

Speaker:

and not others. And before we did the

Speaker:

research, we made things up,

Speaker:

meaning we saw it work once and assumed it was always

Speaker:

the answer. We saw a survivor and declared it

Speaker:

a cure. It's the oldest mistake in

Speaker:

medicine and one we and the

Speaker:

public keep repeating. Fast

Speaker:

forward to the 20th century. Take Dr.

Speaker:

Henry Cotton, a psychiatrist who believed that mental

Speaker:

illness came from hidden infections in the body. So what

Speaker:

did he do? He had his surgeons remove teeth,

Speaker:

tonsils, gallbladders and pieces of colon to

Speaker:

cure psychosis. Many of his patients

Speaker:

died and the rest didn't improve. But he

Speaker:

was celebrated in medical journals. He ran a major

Speaker:

institution, he lectured. He wasn't a

Speaker:

fringe player. He was medicine's main stage.

Speaker:

And that's the real horror. Even

Speaker:

when evidence showed that his surgeries caused harm, his

Speaker:

reputation protected him. Because confidence

Speaker:

often beats data. Hello,

Speaker:

Gary Brecke and Paul Saladino.

Speaker:

Today we don't drill holes in the skull to release

Speaker:

spirits. But we still try to hack the brain

Speaker:

with products that offer less harm but just

Speaker:

as little proof. One of the biggest fears in

Speaker:

America today is dementia. So why do people

Speaker:

turn to things like lion mane's mushroom? Because

Speaker:

it promises to regrow brain cells, boost memory and

Speaker:

prevent Alzheimer's. Some lab studies are

Speaker:

promising, but real clinic evidence, almost

Speaker:

none and has never been repleted.

Speaker:

Still, it is a booming industry.

Speaker:

A $50 a bottle, memory gummies, mushroom

Speaker:

coffee, neurotropics. Meanwhile, two real

Speaker:

diets, the mind and Mediterranean diets, can

Speaker:

reduce dementia risk by almost half.

Speaker:

But eating well doesn't make anybody rich.

Speaker:

We chase the shiny pill and ignore the

Speaker:

olive oil. Let's look at orthopedic

Speaker:

surgery. Some surgeons offer

Speaker:

platelet derived growth factor for injections. They

Speaker:

spin your blood, pull out the platelets and inject them

Speaker:

back. The idea, boost healing,

Speaker:

help your recovery. The evidence,

Speaker:

weak or absent from most uses. And I should know because

Speaker:

I helped publish one of the first studies showing

Speaker:

platelet derived factor helped with

Speaker:

patients with diabetic wounds. That was valid,

Speaker:

but now it's used from everything from tennis elbow to torn

Speaker:

knees to post op shoulders with no proof

Speaker:

but high building codes because that is not

Speaker:

covered by insurance. So it is

Speaker:

a tax on your health care from the

Speaker:

orthopedic surgeon to you that

Speaker:

you pay for. Because the orthopedic surgeon, the

Speaker:

person that you have your confidence in, says this

Speaker:

will help you heal better and recover faster. And

Speaker:

you're just giving your orthopedic surgeon an extra 2000 bucks

Speaker:

to feel good and get a band aid. It's

Speaker:

trepanation with better lighting and

Speaker:

sterile gloves. As I walk through this

Speaker:

museum, one thing is clear. We've always

Speaker:

meant well. But meaning well isn't

Speaker:

enough. Progress in medicine and surgery

Speaker:

means being willing to say we're wrong.

Speaker:

It means asking, does this actually help people?

Speaker:

Science moves forward when we replace story with

Speaker:

evidence. That goes for trepening and

Speaker:

lion's mane mushroom.

This episode was written and recorded by me, Dr. Terri

Speaker:

Simpson, standing right here in the halls of the Royal College of

Speaker:

Surgeons in Edinburgh. You can find references and

Speaker:

more@yourdoctorsorders.com and

Speaker:

forku.com and while I am a board

Speaker:

certified surgeon, I am not your

Speaker:

physician. If you're tempted by PRP Brain

Speaker:

Mushrooms or the next TikTok Brain Booster,

Speaker:

talk to a real doctor and a registered

Speaker:

dietitian. Not to your chiropractor, not

Speaker:

the shaman in Luaman, and not the guy who

Speaker:

drilled a hole in your head for clarity.

Speaker:

This episode was produced by Simpler Media and the man with

Speaker:

more wisdom than any mushroom Evotera.

Speaker:

Have a good week.

Speaker:

Hey Evo, if a wellness influencer told you

Speaker:

mental clarity comes from drilling a hole in your skull,

Speaker:

would you try that? Or do you think a good

Speaker:

IPA would serve just as well?

Speaker:

>> Speaker B: Aye, right. Craft beer might be just the thing

Speaker:

for you, but you're up there in the Scottish

Speaker:

Highlands, so I'd be thinking there, Dr.

Speaker:

Simpson, that a nice single malt might be more what

Speaker:

you're looking for. I can't tell if that's Scottish

Speaker:

or pirate. Anyhow.

Not everything you put in your mouth is good for you.

There’s a lot of medical information thrown around out there. How are you to know what information you can trust, and what’s just plain old quackery? You can’t rely on your own “google fu”. You can’t count on quality medical advice from Facebook. You need a doctor in your corner.

On each episode of Your Doctor’s Orders, Dr. Terry Simpson will cut through the clutter and noise that always seems to follow the latest medical news. He has the unique perspective of a surgeon who has spent years doing molecular virology research and as a skeptic with academic credentials. He’ll help you develop the critical thinking skills so you can recognize evidence-based medicine, busting myths along the way.

The most common medical myths are often disguised as seemingly harmless “food as medicine”. By offering their own brand of medicine via foods, These hucksters are trying to practice medicine without a license. And though they’ll claim “nutrition is not taught in medical schools”, it turns out that’s a myth too. In fact, there’s an entire medical subspecialty called Culinary Medicine, and Dr. Simpson is certified as a Culinary Medicine Specialist.

Where today's nutritional advice is the realm of hucksters, Dr. Simpson is taking it back to the realm of science.
