Your Brain Doesn't Get Sick Overnight: Genetics, Alzheimer's & the Business of Chronic Illness

What if Alzheimer's doesn't begin when someone starts forgetting things? What if the changes happening inside the brain have been building for years, even decades, before the first symptoms appear?

And what if some of those changes are connected to things we're already dealing with every day, like blood sugar, cholesterol, inflammation, hormones, and the health of our cells?

This episode is personal.

After watching my grandfather slowly deteriorate from dementia, I recently discovered that I carry APOE4/E4, a genetic combination associated with a significantly increased risk of Alzheimer's disease.

That discovery sent me down a rabbit hole.

I wanted to understand how insulin resistance can affect the brain, why cholesterol matters for more than heart health, how inflammation and cellular damage may contribute to cognitive decline, and what my genetics could tell me about my own future.

And the more I learned, the more questions I had about the way we approach healthcare.

Because why are we so focused on managing chronic disease after it develops instead of paying closer attention to what's happening in the body years beforehand?

And why does a country that spends so much money on healthcare still struggle to make prevention a priority?

We're going there in this episode.

I'm breaking down the science in everyday language, sharing my own genetic findings, and exploring everything from women's hormones and brain health to resistance training, creatine, GLP-1 medications, and emerging cellular medicine.

We're also talking about the financial incentives behind chronic illness in America, research happening outside the United States, and why I believe we need to stay curious, ask uncomfortable questions, and stop assuming that everything worth knowing has already been discovered.

But more than anything, this episode is about what happens when understanding your biology changes the way you approach your health.

Because I can't change my genetics.

And I can't change what happened to my grandfather.

But I can change what I do with the information I have today.

The workout hasn't changed. My reason for doing it has.

And maybe, after listening, yours will too.

Your DNA is not a sentence. It's information.
