Dementia and Cholesterol Weird 60% Connection

It may surprise you just how much cholesterol affects your risk of dementia.

Turns out, having the wrong cholesterol increases your dementia risk by a whopping 60%.

But here’s the twist—it’s not about keeping cholesterol low, according to a new study in Neurology.

The connection between dementia and cholesterol is actually pretty weird.

Researchers analyzed 9,846 adults (65+) from Australia and the U.S. They tested cholesterol levels every year for three years—then tracked their brain health for 5.5 years.

What did they find?

• People with the biggest cholesterol swings were 60% more likely to develop dementia.
• Those with unstable cholesterol had faster memory decline, slower thinking, and worse verbal fluency.
• LDL (bad cholesterol) swings were the worst—strongly linked to dementia and cognitive decline.
• HDL (good cholesterol) and triglyceride fluctuations? No clear effect.

So what’s the fix?

Be consistent.

Most people’s cholesterol jumps around because they flip between healthy and unhealthy habits.

The key is to stay steady with:

• Diet: Avoid extreme diet changes or going on and off healthy eating.
• Exercise: Keep moving—don’t go all-in for a few months and quit.
• Lifestyle: Sleep, hydration, and stress management matter too.

Here’s why it works…

Cholesterol restricts blood flow to your brain, reducing oxygen levels.

And low oxygen levels are the real root cause behind almost all types of dementia.

The good news? You can easily boost oxygen in your brain without drugs. Here’s a simple technique that does just that…

And if you’re worried about cholesterol, the easiest way to fix it is to cut out this one sneaky ingredient you probably don’t even know you’re eating…
