Is Alzheimer’s Disease Type 3 Diabetes? What You Can Do to Protect Your Brain Health

The Gajer Practice Blogs

Hello Gajer Practice Community,

There’s an emerging field of research that’s shedding new light on Alzheimer’s disease—and it may have a lot to do with insulin resistance. Some researchers are now referring to Alzheimer’s as “Type 3 diabetes” because it appears to be strongly linked to the way our brain uses glucose, much like Type 2 diabetes impacts the body.

What Is Type 3 Diabetes?

  • When we talk about diabetes, we typically think of how the body struggles to process sugar (glucose), leading to high blood sugar levels and insulin resistance. What researchers have found is that a similar process may be happening in the brain for those with Alzheimer’s. The brain becomes resistant to insulin, which is vital for memory and cognitive function. Without proper insulin signaling, the brain can’t use glucose efficiently, leading to cognitive decline and the formation of amyloid plaques and tau tangles—hallmarks of Alzheimer’s disease.

How Insulin Resistance Affects the Brain

  • Just like Type 2 diabetes, insulin resistance in the brain leads to chronic inflammation and damages neurons, making it harder for the brain to process information, form memories, and function normally. Studies show that people with Type 2 diabetes have an increased risk of developing Alzheimer’s later in life, suggesting that the connection between glucose metabolism and brain health is crucial.

Reducing Your Risk of Alzheimer’s

  • The good news is that, just like Type 2 diabetes, you can take steps to reduce your risk of Alzheimer’s disease by addressing factors that improve your insulin sensitivity and overall brain health. Here are some strategies to help protect your brain:

1. Maintain a Healthy Diet

  • A low-sugar, low-refined-carb diet can improve insulin sensitivity and reduce inflammation in the brain. Consider following a diet rich in vegetables, healthy fats (like olive oil and omega-3s), and lean protein. This means steer clear of desserts (aside from special occasions), white bread and pasta and eat dark leafy greens, broccoli, olive oil, avocado, chicken, and fish.

2. Exercise Regularly

  • Exercise is one of the best ways to boost insulin sensitivity and improve brain health. Aerobic exercise like walking, cycling, and swimming can help improve blood flow to the brain and reduce the risk of cognitive decline. Resistance training can also be enormously powerful as healthy muscle greatly improves insulin sensitivity.

3. Manage Blood Sugar Levels

  • If you have pre-diabetes or Type 2 diabetes, controlling your blood sugar levels is essential for reducing your risk of Alzheimer’s. Work with your healthcare provider to monitor and manage your blood sugar, and consider lifestyle changes or medications as needed.

4. Sleep Well

  • Sleep plays a crucial role in memory formation and brain detoxification. Getting at least 7-8 hours of quality sleep each night can reduce the buildup of toxins like beta-amyloid, which is associated with Alzheimer’s.

5. Stay Mentally Active

  • Engage in activities that challenge your brain, such as puzzles, reading, learning new skills, or socializing. Keeping your mind active strengthens neural connections and helps protect against cognitive decline.

6. Reduce Stress

  • Chronic stress increases levels of cortisol, which can harm brain cells and lead to inflammation. Practices like meditation, yoga, or deep breathing can help manage stress and protect your brain over time.

Take Action Now

  • We can’t control all the factors that contribute to Alzheimer’s, but by making healthy choices that support insulin sensitivity and brain health, you can greatly reduce your risk. If you’re concerned about Alzheimer’s or your brain health, I encourage you to come in for a consultation. We’ll work together to develop a personalized plan to protect your cognitive function for years to come.

Warmly,

Dr. Aleksandra Gajer

6 Signs That Perimenopause Is Here

Dear readers, Most women I see in clinic for perimenopause have been told, somewhere along the way, that what they are feeling is "just stress," "just aging," or "just life." Many have been told they are "too young".

The Science of Aging: What We Know and What We Can Do About It

Nobody thinks about their muscle until it's gone. That's the honest truth. Most of my patients come to me focused on fat — how to lose it, where it's coming from, why it won't budge. And fat matters, absolutely. But underneath that conversation is one I think is even more important, especially as we age.
